Thinking of a turbo

[Garfy]

Good morning folk, there is a turbo build come up for sale on the Facebook page. I'm seriously thinking of buying it and am currently talking with the owner (believe he's a member here as well).

My friendly mechanic has quoted £1-2k to fit it over a couple of months in-between his normal work. Not really happy with that.

Anyone know of a workshop down south that would take a build like this on?

[Garfy]

1zz turbo kit

Unused and new
Garrett T28 turbo
manifold (ceramic coated)
elbo (ceramic coated)
down pipe to work with stock or other aftermarket system. Heat wrapped
All braided oil and water lines included.

Air to water chargecooler system with 19mm pipe work reduced to work with the only used item pace chargecooler (from a ford rs). craigdavid water pump

630cc bosch ev14 injectors with plug and play harness adapters.

ecu master back, plug and play harness
Bosch 4.9 wideband

You will need to sort a fitting for the oil return in your sump

You will need to sort a mounting for the charge cooler and the systems water tank

You will need to sort a fused switch power supply to the water pump for the chargecooler

You will need to wire up the wideband to the plug/play harness

As I did not finish my build the ecu has not been mapped.

[shnazzle]

It looked like a good deal to me.
The ecu+lambda+wiring off the shop comes to around 1100 already.
Won't lie, I was tempted. But I'm still firmly in the "not sure about aftermarket turbo" camp.

I was going to buy this kit today but ive decided to carry on building my own when time allows as ive other things going on at moment, its not a bad setup but does need some finishing off and i want to change a few things from how he has it setup so makes sense to carry on with my build as i already have a few bits and bobs.

Going turbo is something you need to think about carefully, a stock car is so little hassle and easy to live with everyday, fitting a turbo depending how far you go puts more stress on things and takes more looking after as well, great fun though as i found when i had one on car earlier this year before engine problems and hence why im building up another kit now engine is sorted.

[Garfy]

Well I've placed dibs on it 
I've spent the last four years mainly working on suspension and underneath the car.
I'm not looking for silly power just up to around the 190hp mark, I believe Damien was looking to get a lot more out of his build so hopefully turning down a little will not stress mine too much.

With one tool bag and a socket set and no garage it's going to be a little too big of a job for myself so I'll source some parts required (sump being one I know about) over the next few months and hopefully look into getting it all fitted early next year for the summer.

Do it, you'll never look back.

Completely transforms the car.

I did mine in the garage over a few months, quite therapeutic.

Please bare in mind that it won't be as reliable as a stock car. It will spit its dummy out. Its not the same as having a tte.

Buy it and sell the T28 on get a t25. Tune to 190 ft lb and leave it at that.

You must be the guy Damien told me was next in line when i changed my mind this morning, good luck with it all its certainly got plenty of potential to make a quick and reliable setup

[jvanzyl]

Have a chat with Dave @Oddshoes  and get some time with him... he's done plenty of turbos and is in Aylesbury..

[Ardent]

Or buy the one that's popped up for sale here.

Chatting on line with him now 🙂

[Garfy]

Went to see Dave (nice guy) he took me for a spin in his.

Very nice

Thinking 240 would be very nice now, bottom end of the safe limit I believe.

Oh dear, what have I gotten into 😁😁😁😁

Further down the road to turbo than I am already!

Single minded John, as I mentioned, I have this year to get the car where I want it.
Next year my focus shifts.

Besides, you have a lot more going on in your life than I have, my family is grown up.

Your time will come 😁

Dont get suckered chasing power down that road lies madness.

I'm considering putting that at the top of every page. 


It saddens me to see the number of people who are suffering unnecessarily with massive bills, unreliable cars and losing interest because of the chase for power.

If you go in expecting it, a budget set aside, risks calculated, mitigations in place.. Fair enough. But I fear people are expecting reliability of stock after shoving 100% more power through, changing the structure of the car, or putting in power plants never intended for the car.
All fun and games and all for modding, tinkering, trying new stuff, but go in informed and prepared.

The second you're considering "How can I do this as cheaply as possibly" you need to stop.

If you do it, do it right. If you don't want to do it right, accept the consequences.
If you can happily deal with the consequences of shoving the boost of a T28 on this tiny block, go for it (mapping, quality components, etc) otherwise go T25 low boost (like the proven TTE/SP200 setup). 

Rant over. I just want to stop seeing disappointed members

[thetyrant]

I would of thought a T28 is ok if you can keep the boost down enough, due to it being larger it will be a little more laggy than a T25 but wouldnt expect a huge difference if car is mapped properly.

Im going T25 again as i like the way it responded on the SP240 kit i had previously, despite it being old turbo technology it does the job and is reliable unit if looked after by all accounts

Further to the pursuit of more power:

One thing I've learned about power is - it's never enough.  As soon as one gets used to a certain level of power, it's so easy to want more.

My CBR 400 could destroy almost any car on acceleration, yet it was not considered a 'powerful' bike, by any means.  It is now possible to buy and ride a road-legal machine with 200 bhp, which is far beyond the riding talent of most people who have them.

I've just finished (with the help of a good friend) getting a long-term supercharger-on-a-two project to the point where it's properly use-able and reliable.  This was done in our own well equipped workshop with ourselves doing all the fabrication, design development and tuning.  The cost still ran well into four figures.  And, yes it's quite a bit quicker than the standard car.  But my old CBR400 would still have it for breakfast!

We did this project on a car I bought for peanuts, with a bad engine, with the idea of getting it all working and then putting the kit on my good car.  Of course. I had to rebuild and install an engine and put right all the faults the cheap car had, making it no longer a 'cheap' car!

Now it's running, am I going to put the kit into my good car?  Hell no.  It would ruin a nice rather original -all Toyota car, that is as it was intended to be by its designer..

It's making a little under 190 bhp, with low-down power delivery you only get from a screw-type supercharger, which was the original design concept.  Squeezing more out of a standard 1ZZ basic engine is asking for serious reliability problems down the road, I think.

That's my ten cents.

Mind you -I do rather like the supercharged car!

I agree. Do you know of a lightweight bonnet and rear deck?  ;-)

The only times I lack power is accelerating up steep inclines on the highway at illegal speed. More lightness I can do with all day.

Back on topic again I think TTE level of grunt and max output is quite enough for the Spyder on the public road. Things can go sideways, literally, quite quick enough.

[Gaz2405]

People just need to be true to themselves when getting into modifying a car beyond its intended uses/power limits.

Out of interest what's the cross over point for expenditure to achieve the equivalent of 190bhp/ per MR2 vs spending the required amount of money to lighten it to get the same power to weight ratio?

Just thinking with all these gripes about reliability, what would you have to spend to get the same performance?

Easy.
Say 1100 kg for a to 190 hp turboed car. That makes 5.78 kg per hp.
Mod the exhaust so the standard 1ZZ has 155 hp and you get the same at 896 kg.

Adding lightness involves a lot of parts deleting which is for free. You know what mine weighs and I spent a whiff over 2k€.
This is totally highjacking the thread though so best stop here.

More back on topic bear in mind that the power to weight is only a fragment of the story. A turbo adds disproportionately extra grunt. Extra power also adds extra top speed which lighness does not.
Lightness however improves cornering and braking.
It is nót a simple comparison and even the exact some kg/hp makes for tótally different cars.
I would say that the crux of the vfm is what rocks yoúr boat.

[1979scotte]

My turbo ac car weighed 1050.
Tbh the extra low down torque a turbo brings makes it a complete different animal IMHO.
Also adding lightness usually makes it less fun aa a daily driver although I'm sure petrus would disagree.

Power to weight of my turbo was probably 210
A 900kg roadster with stock 1zz would be 155 maybe
