What is the max a/r size on the exhaust side of the turbo that we can run on our cars? Please inform me?

 

You can put anything you want on. Doesn't mean its gonna go anywhere. And that is almost an impossible question to answer without knowing your goals or anything

 

this is a dumb question. what are your power goals? what do you intend on doing with the car? lag sucks on the street FYI, it gets old real quick

 

Yeah it does. I wanna twincharge again

 

im currently running an 84 a/r t3 exhaust housing and a 70 a/r compressor housing(gt35). the exhaust housing isnt the problem, its the compressor housing. i have maybe 1/2 inch firewall clearence. i used a large exhaust housing because i wanted a fuel efficient daily driver with a lot of power. im currently building the motor for 25 lbs of boost. with the 84 a/r exhaust housing im not boosting till ~4500 rpm which was my goal.

 

My goal is 400whp and I'm don't know if I want to twincharge or just go turbo. If I went twincharge there is no one in Ohio that would tune for it. So I have to just turbo it. I have a turbo that is 57trim with the cold side being 63 a/r and the hot side being 96a/r. I'm thinking with this turbo I will be spoolin for days bc the hot side is pretty big lol.

 

96 is wayyyyyyy to big. 60-1 ball bearing

 

where do you even find a 57 trim with a hot side that big? What the heck was it for a rotary motor?

 

What's the max rpm you are planning to run? Where do you want the power band? Size engine?

 

I'm planning on 8k rpm and I want my power to be midrange or up top. My engine size is 2.0l.

 

gt3582 should be good. mine spools at ~4500 on my 2.2 auto so that will put you right were you want to be.

 

I think you'd be happy with a GT30r.. Spools quicker than the GT35r and you can still get 400 hp out of it. No need to get that large of turbo if you are only looking for 400..

 

Ok. What turbo did you select already or is that still up in the air?

 

I have a t04b turbo right now. Just need to get exhaust and intake manifold and the other mic. stuff. You know anyone that my have some good deals on intake and exhaust manifold?

 

400whp power goal....GT2871R you'll get 400 and a huge powerband
