Title: SP 240
Post by: Anonymous on December 17, 2006, 18:28
I am just basically thinking about going for the sp240 package. I got the TTET fitted early this year and love it but want more power. It have the SP exhaust and decat pipe waiting to be sent to me but I am worried that that will not be enough for me and in 6 months I will want more. The clutch on my car has started to slip now so that will need done in the near future so I was thinking of getting the clutch, exhaust/de-cat and sp stage 2 done at the same time but at about £3500 is it going to be worth it. What do you guys think ?? Would make it a very fast car, just in two minds about it.

I would love it, but can't really justify the expense. Goes for basic turbo as well.

Going to 240 is one of those diminishing return things, thats already been discussed. The higher the spec, the less you get for your money. In real life the extra you will add on is unlikely to give you the same "thrill" as did the turbo initially, and then doubts set in about value for money etc.

If money (and wife) was no object, I probably would.   s:wink: :wink: s:wink:

I was all for the SP240 upgrade but have since decided to go a different route and have bought a 1995 mk2 turbo.
The reasons simply are:
(i) the standard TTET is a fully daily useable option
(ii) the additional SP240 cost will not add greatly to the resale value
(iii) I have my doubts about what the SP240's additional power will have on the longevity of the engine (only time will tell)
(iv) I need a boot for DC weekends away, as I'm getting fed up with squeezing 3-5 days clothing in the MR2 bags only to see mk2 owners pull out suitcases from their boots!
(v) the SP240's cost seems open ended  s:? :? s:?   to add another £3-4000 on top of the TTET £4000 already spent IMO doesn't represent economical sense
and finally
(vi) maybe after 3 years of Roadster ownership it's time for a change  s:?: :?: s:?:

The cost really isn't worth it, unless you ignored the warranty aspect of the kit when you bought it. If losing the warranty doesn't bother you, and you can afford to throw that money away (you'll get none of it back when it comes to sell), then by all means go for it (power is fun!  s:D :D s:D ).

Personally, I wouldn't. It's not that much different to drive than the standard kit: At least, not unless you're tracking the car every weekend.

I plan to keep the car for another 4/5 years as I love it but get the feeling the odd time I want to change. I have looked at rx-8 and evo's lately but when it comes down to it I dont think I could get rid of her and the amount of dosh that I would loose just scared me. I have had it on the track twice and felt that I needed more power to keep up with the lotus guys but trackdays aren't my big thing really I have just got addicted to the feeling of getting pushed back into the seat.

 The de-cat pipe will give me a bit of boost but in 3-6 months time I think that it wont be enough. Does anyone know if SP have done other cars but there own??

Simon
I don't think so. I calculate less than 15 TTET's at SP and I'm sure if anybody had gone to stage 2 they'd have been at the Dyno Day or at least posted about it.
I cannot justify the cost, although I'm not saying it's too expensive as I'm sure the extra 40+bhp would be much appreciated by some but the additional items that need changing to make the car useable with this additional power makes the decision for you.
Uprated brakes (bigger disks mean bigger wheels etc). There's no point having the additional power if you cannot stop, I feel the stock brakes only just handle the stage 1 TTET.
Now if money was no object then I'd be in the queue, but unfortunately I have to justify the money spent to Deb and it's getting harder to do that based upon the cars impracticalities (ie luggage space), hence buying the mk2 turbo.
I've loved every single mile of the near 27,000 miles in my 2, especially the last 8,500 miles since the TTET was installed  s:D :D s:D  , but the spending on it has now had to stop  s:( :( s:(

Well the deed has nearly been done I am 90% sure that I am going to get the stage 2 TTET done in hopefully January. I was on the phone with Matt @ SP and he has answered all of my questions that I had. It's a fair chunk of money but it will be well spent if it gives me the fun and enjoyment that I have had with stage 1. Will be getting exhaust, decat pipe, clutch and Stage 2.

It's my christmas preseie to myself.  s:D :D s:D    s:D :D s:D

Good decision to go TTET (from your For Sale post).
Are you going stage 1 or straight through to SP240?
Don't know when you've got it scheduled to install but if your going to TTET stage 1, I'd willing meet up so you can have a spin in my car. Perhaps spin is the wrong word for it  s:wink: :wink: s:wink:

Yes I was, along with the SP wheels, car now looks and handles even better. Did you see us?

I'm going for the stage 1 as the car is still under warranty. I'm guessing that the additional mods involved in going stage 2 would invalidate it, otherwise I'd be seriously tempted.

Thanks for the offer David, I live in Kent though, perhaps when I take the car back for the install we could meet up.

Post by: muffdan on January 6, 2007, 12:49
I'm going for the stage 2 next month and can't wait, I think it's worth the £2k. I definitly notice a difference between SPs car and mine and I have the SP down pipe and back box. Matt said their car does a 0-60 of 4.9s measured by GPS speed not the car's speedo. That's very fast.

With regards to brakes, I find the limit is the same as the stock car; the grip of the tyres. If I brake very hard the ABS kicks in so I don't think there's a need to upgrade them.

If I'm not mistaken SP's car is running stock brakes too, they just have steel braded hoses. The hoses only improve the response/feel of the brake pedal, the stopping distances are the same as stock brakes. Thier car has no problems with stopping power or over heating etc. even on track days.

I don't think that I could justify going for the stage 2, especially whilst my car is not running 100% anyway (nought to do with the turbo I don't think) I have found that you get to the speed limit all too quickly with the stage 1, where would you use the extra power?

I was on the phone to Matt and he had said that some one was getting a strut brace fitted. Good decision and you will want more. Just out of interest my car only had 8k miles on it when I went TTET it will be interesting to see what hp it gets when dynoed before stage II.

Just to dig this up again Matt @ sp has said that the SP 240 will do 0-60 in 4.9 sec just wondering whaT 0-100 time you would expect. About 11 sec ??
Title:
Post by: loadswine on January 10, 2007, 23:24
I don't know about how many seconds to 100 mph, but when I had a ride in it on the track at Silverstone, it felt every bit as quick as that. Coming out of the pit lane, we were at similar speeds to things already out on the track and in the space of 1 corner had gone past a ferrari.
I can't really think you'd need a 2 faster than that on the road. The thing that struck me wasn't just how quick it was, but also how civilised.
There was no excess mechanical sounds other than a purposeful growl that grew with revs, and it didn't ever seem harsh.
A very well sorted package imho.

I got it done when I changed my insurance in December. I cost me £1080 which for insurance of my car in NI is quite good. The insurance over here is a rip off. A standard MR2 would be IRO £600 so with all my mods I was reasonably happy.

Title:
Post by: loadswine on January 22, 2007, 20:25
I guess it depends on how long you want the engine to last. I know there are a few guys pushing 260 plus , but without changing the internals, this must be getting near the limit for a standard block.
On the plus side, the smiles generated by that many horses in a 2 may offset any longevity worries.  s:) :) s:)

He is going to tune it to what the engine will take so it should be arround that mark or a little more as I remember him saying that my engine was stronger that there car when I got the TTET fitted. I think anything arround that mark with the tourque figures will be enough.

I planned the extra time because When I got the TTET fitted we were a bit short of time in the end and I had to hot foot it to stranrar in recond time (70mph all the way honest) and didn't want to have to do that again. I would have thought the Stage II would take a day or so. Are you getting tempted ??

They can, but for how long reliably no-one really knows. Considering that each engine is very different in terms of just what it can take, there may be one engine that falls over on 220bhp after a couple of months but another that lives with 280bhp for years.

I seem to recall from reading SC that it's generally the rods that go first in the 1ZZ rather than the pistons (assuming you have the correct fuelling and aren't detonating like a small tactical nuke - because if you are then forged pistons will only give you a bit of breathing room anyway)

Post by: muffdan on January 22, 2007, 21:52
Surely one of the reasons of buying the very expensive TTET (for me anyway) is that is should be bullet proof and comes with a warranty. The SP240 is a very appealing option to get more power from it, but even this is questionable if reliability was a reason for picking the TTET in the first place.

Would we want to push it even more? It would be far cheaper to have gone from stock to Thor Stage III, and then start tinkering with the internals for far higher power gains.

I personally will be going for the SP240 next month. (just waiting for my wife to drop our first offsprint next week). Matt as convinced me that it is developed well within the limits of the engine and not increasing TTET boost levels.... and I like the sound of a 4.9 0-60.

Post by: Anonymous on January 22, 2007, 21:59
ive asked the guys before at MWR

i was just checking old emails and they recommended low compression wiseco pistons and crower rods! they said that would allow me to run a higher boost assuming the tuning and injectors were set up for it!

Post by: Anonymous on January 22, 2007, 22:24
In all this you've got to remember that Toyota took quite a considerable time developing the turbo set up for the 2. There's obviously a limit to the engines capabilities, who knows where that is, but I've a good idea that the TTET was conservatively developed because of that limit.
I'd also like to know if the original 3 year turbo warranty is uneffected by the SP240 upgrade  s:?: :?: s:?:   And for those of you still under the manufacturers 3 year warranty which is honoured under the original TTET package will there be any difference in Toyota's stance  s:?: :?: s:?:

Spot on Dan, that is what I was getting at. I think the odd person on SC has had an engine go after a time, but can't remember their exact circumstances. Some people are quite happy to go for big numbers and when the engine blows drop out the engine and rebuild it.
That won't suit everyone.
I know that the engine isn't going to blow straight away, its just a matter of how long it lasts. I suppose Toyota builds a fairly robust lump in the first place to actually go down the route of an official conversion.
We won't know the answers to the longevity versus power issue until a more miles and more turbos have been done.
SP are confident in the 240 set up and don't doubt it, especially as they have achieved the numbers without cranking up the boost. The kit obviously has potential for more, but how brave do owners want to be?

Where do the limits of the chassis lie also?

Well then maybe its this.....  

the 1zz is "potentialy" strong.

It depends what your starting with, I was lucky a low miles incredible conditions and already a strong car. I virtualy could  keep up with the turbo's to some extent already.

So then based on a good car as a starting point. (Obviously I wouldnt recomend turboing a failing or faltering engine anyway)

Follow on options....

a) plug and play system

I didnt check my engine dont know what im working with or what I am building on ? its not mapped or tuned for my specific car and mods (even my cars personality and behaviour) but a lower power output to be sure its not blowing anything.

b) mapped and tested

The engine has been tuned to perform under various conditions it has had monitoring of boost and knock throughout the process so you are getting a certain amount of guarantee from it, ("there is no knocking at 12psi" - for example) The mixture is monitored with a wideband and all this info can go back into the tune.

------

So to sum up I dont think all turbo's will go bang in time or at some predefined power level, yes if you just blindly piled on the power. But that would be foly without gauges and monitoring.

I dont feel out there on the edge I know my engine is sound. Does everyone with a turbo kit ? I guess not.

To pick up on DavidM's points, warranty is indeed affected by the 240 package.  The TTE parts in themselves are effectively not affected but the warranty on the engine is invalidated.  That said, we have deliberately stuck with the TTE stock boost pressures and worked specifically with air flow (in and out) and fuel to achieve safe (albeit outside the realms of Toyota standards) performance gains.  Going beyond 240 is eminently possible but the laws of diminishing returns set in (especially if we are to keep our "safety margin").

Quote from: "bossman23780"did you ever consider uping the stock boost levels though?!

Of course but: Price vs performance vs reliability.  As per the other thread running, anything is possible.  Another 10ftlb and 20-30bhp would be relatively easy to achieve but we don't have confidence about longevity (theoretical calculations, determine that we are at the safe limit for this capacity of engine) so we won't go further and put our name to it without changing internals.  Ultimately, 400+bhp is possible but you have cooling issues (oil and water), valve issues, con rod (and poss) crank strength issues, driveline strength issues and other potential problems I'm sure.  We could theoretically put together a "stage 3" package but the market is so small that it doesn't make commercial sense.

you mention all those internal changes but im not wanting to push 400bhp

i personally would want just enough to push under the 4.5 sec barrier

For now.   s:twisted: :twisted: s:twisted:    s:twisted: :twisted: s:twisted:


this is going to be interesting seeing as how Matt has just mentioned that no extra Piggyback is used on teh SP240, I'm not seeing how it can be tuned persee?

Post by: muffdan on January 25, 2007, 12:03
Hm, a piggyback is used but maybe it replaces the TTET piggyback, rather than piggyback the piggyback? I don't actually know which.

Post by: TommyD on January 25, 2007, 12:12
SP's ecu replaces the TTET one on the SP240, allowing them to map it to the new injectors and fuel pressure.

Quote from: "bossman23780"[
you mention all those internal changes but I'm not wanting to push 400bhp

i personally would want just enough to push under the 4.5 sec barrier

To go further you need to increase boost.  If you increase boost, you increase piston crown temperatures beyond the limit of cast pistons (this is the theory, by the way), you could deal with this by introducing oil jets or forged pistons (or both), or a bigger/better intercooler.  To increase boost you're going to need a boost controller and if you're going to change the pistons you're going to need to open the engine in which case the upcost of changing rods as well is relatively low.  If you do that you're as well to shoot as high as you can but you'd probably want to uprate the radiator and introduce an oil cooler.  To get "a bit more" than the SP240 package with an IC upgrade is realistic but to get below 4.5 secs 0-60 you need more than 300bhp (based on our TVR experience) which would definitely require most of the enhancements I've mentioned.

so then what youre saying is, aswell as the mods needed for the SP240, i would need :

Pistons required
Rods recommended
Boost Controller required
Intercooler recommended
Radiator recommened
Oil Cooler recommended

i already got an upgrade on the radiator but would that be sufficant, its the C-One radiator and i thought these cars had oil coolers already or has it but it would just need upgrading?! so i wouldnt need any other engine parts then like cams, springs, valves .. etc

Just got in from my return from SP after getting stage II fitted. Totally awesome. At first I didn't think there was a lot of difference in that and TTET but once you get the chance to really boot it and rev the nuts of it, it really is superb. It now pulls to the red lin in every gear which I can say is so fast it is scary. The TTET is fast but this is super fast, I still haven't really got a chance to push it hard but what I have done has been awesome.

I have lots of pic's but am to tired to upload them will do it tomorrow including the dyno graph. It came out at 237bhp and 242lbf of tourque which as Matt has said was not the most powerfull map but is set up to be conservative as I don't want my enging to go pop.

I spotted our SP240 on a bit of YouTube footage - it's launching from the lights next to a 4 litre TVR Chimaera and a 5 litre TVR Griffith. The camera car is an Audi RS4.

The moment to look for is at 1:23    s:lol: :lol: s:lol:

I have had a chance to upload some of the pic's from the Stage II install last week.

Before picture taken at 7.30 after a long drive.

The work in progress for SP. Working on the Lotus supercharger.

The exhaust and decat pipe are on.

(http://i66.photobucket.com/albums/h247/simonmr2/Car_0151.jpg)
The old clutch has still a bit of life but it was changed for a exedy clutch. Which is harsh but I am getting used to it now.The clutch was sliping in 3rd and 4th so it had to go.

Oh it's red and clean. Bling.

(http://i66.photobucket.com/albums/h247/simonmr2/Car_0171.jpg)

It's on the dyno at WRC and the guys are doing the tune. I had never saw this being done and it was amazing but very loud and cold. The 2 guys from weltmeister that did the dyno really know there stuff.

(http://i66.photobucket.com/albums/h247/simonmr2/Car_0261.jpg)

The TTET power came out at 178bhp and 220lbf torque. Torque figure is wrong and I was told why but I really didn't understand it. But the bhp was about what I was expecting. Stage II came out at 237 bhp and 242 lbf of tourque.

(http://i66.photobucket.com/albums/h247/simonmr2/Car_0211.jpg)

The car is finished for now. I really do love the SP wheels and they really do help with the traction as well as the looks.

I watched the start of it then went back to the Hotel as it was getting quite late on and I was hungry and thirsty. Matt didn't want me to watch it as he wanted me to drive the car then see the dyno graph. There was a couple of other cars there getting dynoed and the owners of them were able to watch.

Phill good vid's loving your work, keep it up.

Post by: Anonymous on March 12, 2007, 22:13
Yeah it is still awesome there is so much power. As its now starting to dry up I have been able to push it a bit more and I know that there is even more left that I havent even got to yet. I have a trackday on Sunday and I think that it will be really interesting to see how it compares to the lotus guys that are going. My boss drives a cayman s and he near pooed his pants when he drove it. Just waiting on my FSB from SP should be here tomorrow and that will stiffen the front up.

No major problems had a bolt I needed to fix and the CEL which Matt is sorting out ATM so its basically nothing. I am really happy because I do look after the car but it does get a bit of abuse on a daily basis, that is what it's there for.

Bossman what's happening with yours ATM ?

well my car has had some other issues to deal with but should be ready at the end of the week! he says   s:? :? s:?   all the 240 bits are on just needs mapping!
but for the last few weeks ive been driving SP's 240 and just wondered what youre impressions were, so far i like   s:D :D s:D  

what clutch are you running, cus the SP one is so heavy, im running the TRD mine and its fantastic, but this takes some getting use to! makes me think what clutch to upgrade to   s:? :? s:?

I have the exedy cerametalic clutch which at first was a bit brutal but after a couple of thousand miles it has started to become more user friendly and I love it now. The thing about the sp240 is after a year of TTET driving it is really hard to change the way you drive I never took the TTET over 5K revs but now it's so much fun up there. What are your thoughts ?

I think its a really good upgrade, not quite sure if its worth 2K, but i would definitly say anyone with the TTET it is a must!   s8) 8) s8)  
got to say welldone to Matt and Chris and anyone else involved for making this setup feel just like the TTET, even tho you get the extra power it still feels so smooth and ive got to say it doesnt effect the mpg as much as would have thought aswell, dont know if you have noticed that Simon!

carnt say its changed my style! i always took the revs to the limit anyways  s:wink: :wink: s:wink:

Just a update on the SP240. After a couple of months now I have had the chance to reflect on how good it really is. I did a trackday on Sunday and it was totally awesome. On arrival I was checking out what other cars there were and I was really worried when I saw 3 elises and 4 exige's 1 was a supercharged. I know it's not a race but I wanted to show what it could really do. As it turned out the only car that was able to over take my was the exige s but I knew that would be the case.

The phat tyres really gave me loads mor traction on the snowy track and the new brakeline's with the RBF 600 really surprised me how late I could leave the braking. I had loads of people looking at the car as they were shocked how a MR2 was able to overtake them. The best one was drag racing a M3 down the back straight and then outbraking him into the hairpin priceless.

The was the car pulls in all gears really lends it to the track and I cant fault it one bit. I used Millers CVL for the first time and thought it was verry good but would only use it for trackdays as it's quite pricy.

A couple of pics from the day

So picked up my 2 today from SP and i like   s:) :) s:)  , its producing 225.9 BHP and 225 ft/lbs of torque, dont worry people (Liz   s:) :) s:)  ), theres a reason why, because im running the PPE High Flow Cat, oh and i now have the SP exhaust!

Well after driving mine for the first time and comparing it to SP's car that i have been driving daily for the past number of weeks, i definitly know my handles much better in the corners, im running the Sportivo stuts and thats the only difference that i can think of for me having an edge over the SP car.
Straight line speed, well the SP car still has the edge and with the fatter tyres and bigger wheels that SP have, the car does feel more planted but strangely not in the corners (oh and i didnt hold back in the SP car   s:wink: :wink: s:wink: ).
WOW, now not too sure what make SP's clutch is but i do know its a heavy duty one and it is HEAVY! i got in mine today and it was like butter, my first thoughts were, ITS BROKEN!
Quite pleased with the noise the car is producing, with the downpipe on SP, i thought it was a tad too aggresive for me whereas mine is suttle but it still has to go through the breaking in period!

Overall, im delighted with the car, so far that is   s:) :) s:)  going to give a few runs tommorrow   s:P :P s:P

Mine is a normalish TTET (but with the addition of the SP downpipe and exhaust) and it is putting out 203.5 and 211 ft/lbs torque.

Thats quite a good increase Bossman and I bet it drives lovely - but I thought it was called the SP 240 because that is approximately what it should put out?
