Turbo selection (didnt find what i want to know in the search)
Hey gotta turbo selection question I didnt find anything in the search so if this is asked alot dont get mad. ;D
I am going to be boosting my 98 prelude h22a4. (i know all about the weak ringlands and sleeves) I bought a t04e .57 .63 turbo for my lude and i am planning on running 7 psi (for now). Will the to4e since it makes more CFM than a smaller turbo make more engine internal wear? |
Re:Turbo selection (didnt find what i want to know in the search)
I think psi. is psi. no matter what turbo is making it.There shouldnt be a difference.The bigger exhaust on that will just make the turbo more efficient at high RPMs.A smaller turbo say a .48 would stop boosting sooner than that .63.That .63 should make boost till redline on that engine.

just a regular t04e? not a hybrid? if so, thats waay too big

wrong. 7psi at 200 cfm aint 7psi at 1000 cfm..
CFM is the big number. much like a 6" pipe with 10psi and a 1/8" pipe with 10psi. more volume in the 6" |
Re:Turbo selection (didnt find what i want to know in the search)
I think it will be fine. As for more wear I don't think so. The larger turbo usually produces less heat than a smaller one. We did an SHO, upgraded from a grand national turbo to a TO4B 1.19 turbine, running 16psi non intercooled and it doesn't detonate like the intercooled GN turbo. Non Intercooled 9psi, 347whp. The point is, I don't think you have anything to worry about

a T4 is not to big. Actually for an H22 its about right, especially with the trim specs on the turbo. And the Dr. is right. 7 pounds with a rhb5 is different than 7 pounds with a t88. Think of a squirt gun and a water hose, they may both be putting out 7 pounds worth of pressure, but which is putting out more water? hmmmmmmmmm...........

he didnt say the trim specs, just the a/r's. i guess im not up on h22 turbos...i just think a straight t04e would be too big
