Turbo: whats needed

[Anonymous]

Hi guys, havent quite bought my mr2 yet as im looking if its financially viable for the kindda perfromance i want. been looking at some ways of upping the power and it seems that a turbo kits is the cheapesty option while still being an effective one (the 2zz swap doesnt seem to be much of a gain for the price and the supercharger route is also very expensive). The kit i found was the MWR turbo kit, but on the same site it was also suggested that i buy a apexi power fc and some 630 cc injectors. what io would like to know is firstly are these "needed" or are they just being sold to me to make more money and secondly what else is needed for the car to run smooth. here is the link to the kit:

I appreciate any help and apolagise if this has already been posted.

thanks,

Yes, larger injectors and an ECU (piggyback or stand alone) is needed IMHO! Technically you can make kits work without these but it's risky and it's compromising the setup.

[Anonymous]

just to add, if i were to but the MWR kit it does say the kit comes with insteructions, could any1 tell me from experiance weather or not given alot of free time would i be able to fit this kit. my brother is mechanical minded, he did like a course in mechanics and also services cars etc and has like changed gearbox on his 200sx, we lifted an engine outta my ek4 civic and dismatled the loom etc. or would you advice i get this fitted by a specialist given the complexity of it being mid engine?

again thanks your help if given,
Tristan

If he can change a gearbox, he can fit a turbo kit, IMHO  s:) s:)

Before you go buying a turbo you need to learn how to drive the car first.

how do you know i dont?

And do you

I don't know the reputation of the MWR kit, but it's sensible to uprate the injectors .. however I would suggest the 630cc injectors are way beyond what is needed.

I would recommend a standalone ECU like the Apexi pfc, simply because it gives you the most opportunity to get the best from the kit. Some piggy backs can be stable but they can also suffer from map "competition" between the standard ecu and the piggy back. Also best to aim for the GT Garrett turbos over the T series as they spool up smoother and quicker.

Krank Vents are also a good recommendation and imho charge-cooler over intercooler, they're just more capable of giving a stable intake temperature that is consistent.

+1 not meant as a quick swipe honest.  If your used to RWD mid engined setups then fine.  Just don't think its like driving a FWD hot hatch with similar power or you'll end up in a hedge backwards

Also before you charge it, tyres makes and pressures!

[AmeR]

Just a note on what FGRob and SG have said there:

FWD hatchbacks, coupes etc drive completely different to the MR2, as do 200SXs and many other rear wheel drive front engine motors. It is worth having the car a little while and getting used to it and getting the suspension, bracing, etc more to your (and a turbo's) liking before boosting it. It's a great car even in standard guise and well worth getting to know it before increasing the power.

It isn't a questioning of your drivability nor experience (as I obviously do not know either of these), merely advice from people who have experience of these cars.  s:D s:D

First up, what sort of power and torque are you after?

For that kit, you will need to uprate your clutch as the standard one is unlikely to hold the torque.

Depending on how much power you want to make, you will need uprated injectors. Personally, even for their base kit, I reckon the injectors need to be upped significantly.

And of course, sort out chassis bracing and handling enhancements before adding power.

You could have a chat with Matt on here (Mattperformance) as by the time you have import cost and duty on the MWR kit you will be spending the sort of money his kits come in at.

probably true that, when i bought my Hass in from the states exchange rate was 2-1 and there was zero UK competition

with current Vat and duty and exchaneg rate, you may well be better buying domestic

though personally I prefer the emanage that comes with the US kit rather than the unichip Matt uses

[ChrisGB]

Forgot to add, whatever you set up with, the stock exhaust system will choke it, so some sort of aftermarket exhaust with a 2.5" bore, which is of course supplied with the MWR kit.

If you haven't got a '2 yet, then why not just go for one that is already turbo'd.....

never touch a car that has already been modified mate, cant know for sure whats done to it  s:) s:) . and as for the driving i will for a while be using the car as stock as im putting the arp perfromance kit on it, and ye i get the diff bewteen rear and front wheel drive and heard of the mr2's snappy oversteer, but i just prefer to jump in at the deep end (much to the annoyance of my brother and father). good point about the power, last car i had was only a ek4 vti civic and at 170bhp felt a bit slow. just to turn the convo slightly, what sort of import costs n tax would i be looking at for the below:

also i assume shipping costs are irrelevant of the tax and import costs?

thanks again guys

It should be providing the shipping invoice does not included it in the final price, you need to speak to the seller to make sure he excludes it.

Andy's car has the SP kit fitted by MattPerformance (member on here).  You'd be hard pushed to find a turbo kit more reliable than one of SPs.  I'd put money on it being a more reliable option because;

A) its a tried and tested kit, based on the Toyota TTE kit.
B) It was installed by MattPerformance (member) whos had a ton of experience on the MR2 and lots of practice with installing Turbos on them.
C) It was mapped by Redline tuning (correct me if I'm wrong Andy) who are good at mapping and again have done a fair few MR2 turbo's.

A bit of a far-reaching statement, surely the likes of an odd twin exhaust doesn't hurt. But one of the reasons why it is usually suggested buying a long standing club member's car, a lot more information about it available in the public domain i.e. here.   s:wink: :wink: s:wink:  , and you can also get a feel of the type of person that owned it.

At the end of the day the "cost" is what it takes to get it to your front door, whether its charged by the supplier or one you have to bear, like VAT, so always do your sums beforehand, and shipping costs ARE included in the landed cost for VAT and duty calculations.

That's why you need a shipping invoice, instead of your actual invoice which is what we do when shipping overseas.

Kit $2999
+ International shipping $1300
= $4299 = roughly £2600
+ Import tax may be around 5%
= £2730
+ VAT 20%

Total cost to get the kit to you may be around £3276

Isn't Matt doing the 200bhp SP kit fitted for not that much more than that, was about £3500 IIRC

[muffdan]

Dave, the shipping quote calculated is for a body kit; not a turbo kit. Bit of a topic drift there catching you out!  s:) s:)

Maybe you are tempted then, missing your turbo'd '2?   s:wink: :wink: s:wink:  

For the record all the above is correct. We are all entitled to our opinions, but if/when I sell my car I will sleep very easy at night knowing how well it has been looked after and treated.

To the OP - i spent a lot of time looking at the turbo options and every time it came back to the SP one in terms of overall value (reliability, performance, complete package, fitment etc...). Will look forward to hearing what car and turbo options you end up going for.

Andy.

[Wabbitkilla]

I agree with all of the above, except .... go with a standalone ECU ... Apexi PFC preferably cost/function considered.
