Assuming my existing turbo is dead, which it appears to be.

A question to those of you that have fitted garrett turbos around this size.

What worked for you?

I believe that getting a GT35R with T4 compatable housing (0.63) would work best from my limited investigation.

Looking at being able to get 600hp eventually and wanted turbo that would handle it. I have an 200 block / greys+greens / RS500 intercooler already so at least I have a start, will need to think about throttle body though. (note not sure on injectors, would need siemens once got to that I assume)

What housing sizes and specs worked... what other bits did you change...

Thanks

On further investigation it seems that for my car on the road a bit that GT30 will be better, not as much power but broader, still getting advise though... I only know one person that has a GT30 on, dont know any with GT35.... and as you know it also depends on the rest of the cars setup

 

is there a gt30 with a internal of 35 spec?

 

3076 is probably closest.

Couple of guys with them on SR20's making 500+

if you have that amount of power you should really use 8 grey injecters

 

if buying injectors; you are much better off with siemens 83lbs

 

Gavan;

what turbo do you have currently? the problem with wanting 600hp eventually means you wont be using the right turbo for the time being. That means you'll have a turbo too big and it will be nasty to drive and probably be a bit laggy

a gt3076 will get you circa 550hp with the correct other bits (cams, ported head, inlet, injectors etc), as will a Roller Bearing t4. if you want 600hp then i think you'll need to look at the gt3082(aka gt3040r)

i "think" anything over a gt3071r will have to be externally gated

with regards to the inlet, a hart inlet should do the trick nicely

 

opps, old thread!
