I have now just started rebuilding my02 sti so ripping the engine out for a 2.1 build and was looking at a rotated setup but just been on scoobyclinics website and see a GT30 or a GT35....... which is the recommended turbo to get or that ppl use?

 

a bloke i use for work on my car has a rotated setup with the gt35 making well over 600hp with meth!

 

do you know what size housing and that he was using and im looking for a comfortable 550bhp so a 2.1 stroker kit and was thinking a GT30 but the GT35 looks good too just dont want it to be to laggy

 

i have,nt got a clue mate i can ask him for you though?

All i know is its a CDB fully forged etc etc and £££££££ lol

 

Hi there

If you are going with 2.1L,assume you will be running AVCS heads,if yes I would go down the route of the GT30,on 2.1L will be nice and spooly

Second bit what power you are thinking to run?! And from this I would go and decide which is best option,plus you are looking more for track or drag strip etc.

Are the AVCS head on the sti as standard or just the jdm version? And I looking for 550 bhp comfortable and it's just gonna be a weekend toy mate so dunno wether drag or track to be honest

 

Yes you have already AVCS on yours STi

For 550bhp I would go down the route of the GT30 and you should have nice and comfortable 550bhp without the doubts

What spec of the 2.1L you are looking to have built?



Jura

 

GT35 has been run on 2.1 but as Jura says a GT30 is the way to go for better spooling.SJ.

 

I haven't looked into full specs of the 2.1 build as of yet but that's the way I wanna go, so any help on specs would be helpful

 

Hi there

Depends on budget,speak to few builders here and ask them for spec

I would go with Mahle Pistons(just wish Cosworth pistons are available too for 2.1)
Rods: K1,Carrillo, Cosworth etc
Crank:EJ257
HG:Cosworth
Headstuds: 11mm Cosworth 260k psi if budget allow get 14mm headstud conversion
OEM Gasket rebuild kit
ACL Race Bearings

plus few other bits and bobs,really speak with engine builders here,I'm sure they will spec for you nice engine which will hold that power without the problem on longer run

yeah cool cheers for that mate much appreciated, im in no rush at all for the build as its just reshelling my car after the acciedent, so the budget is not a massive problem if i have to save then thats what ill have to do
