I had a 60trim/t3 .63AR before with a long runner turbo manifold...that netted 28psi by 4500rpms. 2.4L 8:1CR stock head. Im switching to a shorter ram horn manifold that wont loose as much thermal energy and exhaust velocity...and looking for a turbo that will make power sooner and hold the power to 8k. I'd like to make 400ft lbs by 3500 and make 400+whp from 4000-8000....i know it wont be linear, but I'd like to fatten the torque curve and work on turbo response. I'm thinking about a GT28R with an .82 Housing....but Im not sure it will make the power that I need. A 30R is a bit oversized for my goals, but has the response that Im looking for. i have a 3 bar map and standalone, so the PR wont make a difference as long as we dont go over 33+psi

 

Is this going to be on an SRT-4? K series? H series? S2000?

SRT4

 

GT2817rs if you have the money.

Otherwise using a 50 trim t04e wheel with a smaller stage II turbine wheel might work well.

Also looking into smaller Holsets with a split turbine housing might be a good idea. Split turbine housings have been known to improve spool time dramatically.

 

GT30r

 

I see it's going to be for an SRT-4. GT30R is going to be your best bet

 

I'd say GT3071R. The GT3076R would be nice, but I doubt if you would get to full boost and have 400+ lb-ft by 3500 rpm. The GT3076R seems to spool a bit later than the GT3071R.

Yeah. I missed the part about 3500RPM. The GT30R wont give you 400ft-lbs by 3500RPM. I would suggest trying a GT2871R with different turbine A/R combinations

 

Its an 2.4L Stratus block with SRT-4 Internals in a 1st gen...its all kinds of cluster fucked.

I think the 30r will do pretty well...only problem now is affording one lol.

 

dont need to say anything just look



gt3076r rocks

 

I bet that will carry very well to 8k rpms. Its too bad they didnt dyno it out to 8k.

30r is looking REALLY good. thanks guys

Stock Intake Manifold and Spacer
Stock Head besides cams...no PnP



tuning baby

mad props to owner

 

Here's a 3076R with a 0.82 a/r turbine housing on a F22C1...

Peak boost was 16 psi around 5000-5500 rpm IIRC dropping to 10 by redline (tuned that way- the injectors were maxed out and couldn't take more boost). This was on pump gas and 9.5:1 compression.
