i have a stock d15b vtec
my turbo is a t3/t4 .50 AR..is that too big or would i spool it?what RPM?

thanks

 

what manifold, what exhaust? the .50 a/r is the compressor housing? what about the turbine housing?

btw, welcome to hmt. post some pics of your rex, ritz.

 

I'm gonna guess it's a generic ssautocrap t3/to4e 50 trim with a .63 exhaust a/r...the $200 2 week special. I think he's just confused about the difference between trim and a/r.

 

You need to know trim.
Learn to read a compressor map and understand the flow requirements for your motor at HP.
I know nothing of VTEC, but my old school 2.4L motor (sub 300hp) the t3/t04 V-trim was too big. It'd spool, but there are better more efficient turbos out there for small displacement.
55AR.. I forget the trim.

 

im using a ching chang chong meyow turbo on this springs progject ...... t3/4 .57 trim .63 hot and cold.... its on a b18 and it is plenty eficient......

it will spool on the d16, but imo its a little to big for that motor...

 

I had the same setup on the d15b for a little while. It took forever to spool that turbo. Like 5500 rpm!! ------- sucks. At that point full boost to 11 psi is almost instant. Welcome to HMT and turbo lag **** smoker.

 

Yes.









Your next post should be ****. You have been warned. Welcome to HMT ****.

 

Wow. You guys sure took it easy on him. lol

 

I think that is my problem....
