400bhp Turbo
 

After a new turbo for my 2002 Bug STi.

Still has the factory turbo on it and am looking for around 400bhp with supporting mods.

What turbos have people used to achieve this power?

I have looked at the SC turbos but will a SC38 perform than a SC42 or is the 38 really just a 380bhp turbo.

SC 38 will need meth to hit 400 & even then it's not guaranteed. Go for a 42 but even then you will need supporting mods to achieve your goal.

Engine tuner T36 could be an option? :)

T36 is a bit bigger though, puts it right into the sc46+ range which appears to out spool it. Not aware of any back to backs being run to give a true comaprison

MD range?

Would like to see how the T36 spools on a 2.0ltr newage? Would it be quite laggy?

I have just had a SC38 fitted to my car. 53 plate STi

Only engine mods currently are full turbo back 3" cobra exhaust, panel K&N airfilter, OS map, made 371bhp 341 torque @ SRR 2 weeks ago :)
Very good turbo pulls 1.5 bar of boost all the way to about 6600rpm

I will be adding RCM headers, GGR cone airfilter, and a Wizards of NOS kit in the new year, to take the car where i want it to be.
Should quite comfortably see around 400+bhp ;)

i have bought one of these to go on my 2.1 build.
if its too laggy i will have to drop a gear before i accelerate. :thumb:

Nice spec mate.

Why didn't you go for the SC42 so you would get the 400bhp figure.?

As has been said on here many times before, some cars easily make power while others don't regardless of mods. In theory an SC42 should make 400bhp but there are plenty of cars that don't come close.

I did consider the sc42 and t36 before i made my choice.
The 38 covered off everything for me, good early spool plus good boost till the redline, i always had a plan to add nitros at some stage (having used the stuff for 7+years) but i wanted a drivable,fast, well sorted car, i dont really have any intension of figure chasing. (Done that in the past, and it wasnt fun oddly enough)
I run the 1/4 mile for fun, nitros helps hugely with that lol

There's issues with t36 that's why turbo technic aren't selling them any more

Can you tell me more ?

Passing oil that's all I know saw post on Facebook about them couple weeks ago

Lad I know has a t36 thats already in for a rebuild after 1000 miles. Saw the pics on facebook, smoking badly, oil contaminated and under performing. Apparently they use old t3 housings on them which is a 20 year old design and theyre also not roller bearing. I'm in the process of heading for 400 on mine and will probably go with one of the MD's as theyre proven/reliable.

Sc' & md's all tried and tested can't wrong with them.

Stay away from flavour of the month turbos like the t36

Dont Enginetuner sell them ?
I thought they were a quality turbo,it seems i am wrong.

Not anymore

Or you could go Owen Turbo with a spec for what you want. I have a Chevron/Owen standard position on mine on the standard 2 litre and it's defiantly not shy

May also look at getting a Blouch from the US as that basically what an SC is

Sc are customised versions though so unlikley to get as a good a result

Looking at the SC38 and the SC42, they both have a massive price difference. It is around £400 difference.

Stewart I don't really think they are same spec and you will get charged customs etc so not really a saving

And as for t36. I'm waiting for them to come back as I was told by Alan they had issues with oil return etc but it's very unlikely now as it's been ages so assuming it's being brushed under the carpet, funnily enough they now are recommending precision turbos hmmm?

So may aswell just go for a tried n tested turbo now

This is the sit rep. (Situation Report)

The T36 has been identified as the source of smoking from the exhaust in certain conditions. The tendency is to push oil through the ring seal on the overrun. Not every car that has one fitted has had this issue. We suspect the cause may be due to variations in the breathers exacerbating an existing issue.
That might explain why some do and some don't. Of course it's annoying being not obvious to begin with.
The T36 doesn't use "Old T3 housings" they are a variation and of course new. In any event the difficulty is in the core and not the housing.
I've been in touch with one owner who purchased one second hand and believes the turbo is the cause of lack of power. We aren't so sure having discussed it, as it doesn't match our findings on other cars.
Power has never been the issue, in fact we've had very good figures indeed, along with amazing spool from the roller bearing versions we've had on test.
Yes, the new ones will come with a roller bearing core.
We have always supplied all the turbos going, including all the ones spoken of. We like the T36 for several reasons. It's spooly, gives the power, is made in the UK and it's several hundred pounds cheaper than all the others.
We are in constant contact with TT and will be testing the latest version as soon as we have them. Anyone with an older plain core version that has any issues can contact me direct.

Nobody is brushing anything under any carpet!
We tested the Precision when it first arrived, we've supplied a few, we've also fitted several MDx555's. they all have their merits, and are not all the same.

Is it possible to run a safe 400bhp on a standard Bugeye STI engine?

Was thinking of doing this myself.

Lots of people have got away with that one, which is the healthy way to look at it! We hit 475 bhp from a stock STi engine recently.

Sorry Alan for being blunt, but I'm kind of getting fed up with waiting on this, hence my frustration :thumb:
I've now chosen to spend my money on a 6 speed so hopefully the t36 will be on the market when I'm ready again so we shall just wait and see and hopefully the tests are good when they are put right and no issues from them.
Then I will be more enthusiastic to buy as it ticks all my boxes the spec I'm building my car for :thumb:

Are the standard headers good for 400bhp or will they need upgrading.
