I'm trying to decide which turbo to go with for my built 2.0L setup. I'm using a Dart block with custom Wiseco's yielding 8.9:1 after all machine work, 85x89mm bore/stroke. The head is RLZ ported, +1mm intake side, flows over 300cfm at .500 lift. I'm in the middle of picking the turbo I want to run on it. I talked with my tuner tonight (blundar) and he gave me some good insight. I want something that will start building boost by at least 45-5000. We will tune on pump gas (93 octane) and on race gas. I was looking into the GT4088R, but don't know on it now. I still need to get a manifold as well, looking at a topmount setup or a HyTech if I'm able to find one. Any insight or advice on what to go with is greatly appreciated.

 

gt35r or 30r will be good for 400-450hp range great streetable turbo

 

Yea, the car isn't a DD, but does see street use, I want to hit the 600 mark if I can at peak boost at say 30-35lbs on race gas. 450ish on pump.

 

i dont think the 40R would spool until after 5k. but since its a race car, who cares!

full throttle or no throttle!

 

600 easy on a 35R

 

Yup, 35r FTW

 

40r will spool as fast as a 35r with a twin sroll manifold.

I have one forsale, PM me

 

That's what I planned to do was a split scroll manifold to decrese spool time. I'll PM you man!

 

I say 35R FTW!!!

 

35R for sure

thats what im doim this year on my 84mm GE sleeved LS
