Turbo comparison
 

I was wondering how much better is:

a 57 trim with a .63 a/r turbine housing and a .70 a/r compressor housing

over a

57 trim with a .63 a/r turbine housing with a .50 a/r compressor side


what kind of whp can i see on a ls motor with about 15psi with these turbos?


thanks

Re: Turbo comparison
 

is this LS built? It will need to be with that big ass turbo you mentioned. With 15 psi you should be able to see the 350-400whp mark.

BTW: your second turbo you mentioned sucks. The first one is too damn big.

Re: Turbo comparison
 

so the .70a/r trim is good for a decent amount of whp

why is it to big?

Re: Turbo comparison
 

how does the second one suck and first one is too big? the only difference is the comp. a/r

Re: Turbo comparison
 

thats what i was thinking

Re: Turbo comparison
 

are they both t04e comp. housings? or is the .50 a t04b? either way, the .63 turbine in not too big and will spool fine, i had a straight t3 on my b16 with .63 turbine and spooled extremely quick. either one of those will be good on a b18

i know the .70 is a t04e the .50 might be a t04b
