not supra related, but my new mr2 is a toyotagt now, as the timing is 20c out and lamba reading 19,

 

ive put my car in as its onlt making 0.6bar on the t88-34d turbo, a load of checks were done today,

 

tested boost contoller (working fine)

wastegate

turbo for play, damage (no noticable damage)

timing (way out)

idle (way out)

compresion test (14 good)

etc

 

car is set up so lean its ready for DET:eek:

 

car has been left, and f-con is by-by and link with ryan g is in!

 

the car is not making much boost, so could be turbo related, so might needing to change,

 

What flange fittings are normally used on T88-34D Greddy turbos?

 

and what turbo for true 500hp

 

thanks

The greddy T88-34D is the biggest of the T88's and capable of 900+bhp. Awesome turbo :cool: perhaps too big for an MR2 I'd go T04R :)

 

isnt that really big also, is it likely to fit on my manifold?

 

Typical of Japanese tuned cars, make as much power as possible....Detonation? Nah dont worry about that!

 

Bearing in mind the T88 is MASSIVE on a Supra, id say a GT35R would be the best to go for.

 

 

yeh, typical japanese, i was hoping the worst on the compression test...........

 

whats the gt35r rated to, and do hks, greddy make units, or someone unlike monkey xs-power shite

GT35R is around the 450 - 500 bhp mark on the MR2

 

The GT35R is a Garret unit, not Precision or XS ;)

 

I suppose Greddy/HKS wise you may want to consider dropping down to a T78 or maybe an HKS T04z? I still reckon they may be too big, and you will just be paying for a name.

 

The T88 family is likely to be far too big for the Mr2, it just wont produce enough gas to spool it mate.

GT35R / GT3540 seem to be the turbos of choice, it's what the 10 second cars were running at TOTB if memory serves me right, one on a tired engine, one on a new untested one - on a proper setup you should be tempting high 9's

 

Worked OK on the handling course too.

 

Is yours still a 2 litre? The 88s seem to work OK for drag racing on the 2.2 cars but the GT turbos are catching up...

the problem might be the wastgate spring which has gone?

 

That won't be helping :)

 

If the budget allows for it get the know issues fixed, get mapped on the T88 and you might be quite happy with it.

 

It's never going to be an ultra responsive fast road and track car with that turbo but it'll be rather fun when it does eventually boost.

just to bump this thread up again.

 

the t88 is fine and working,

 

but will look to change to a gt35 after the new year,

 

now, are there many different types of gt35? which one would i be advised to get, and which to stay clear of?

 

many thanks, from the guys which dont take 4weeks to post a reply 'mr2 forum':D

Ok, i was going by the original question for 500bhp which would be great in a light car like an MR2.

With the extra lag the car would be slower in the first 4 gears imo and i bet you wont get full boost till past 4k with the gt35, which is not ideal for a track car imo.:)
