I'm having trouble deciding on which turbo to get for my ls...I'm giving my best attempt at figuring out how to read compressor maps....but I don't want to trust my own guess. so any help with this would be appreciated. My goal is to have 250-275whp and run mid to low 13's on a stock block b18b1 in my eg.
the turbos i've been leaning towards is a t3/t4 with a .42 a/r compressor and .48 a/r turbine or a t3/t40e with a .50 a/r compressor and .63 a/r turbine and it's a 57 trim. but i've heard that any t3/t4 will be too big period but idk.
now i found someone selling a greddy kit in the classifieds in a local forum with an 18g turbo...how big is this turbo compared to a t3 or t3/t4? i know nothing about it, i'm awaiting his reply for more info...
any help will be greatly appreciated, thanks in advance.

good man

 

you'll find my setup in that thread, as well as many others, but real quick- dont get the t3 42/48. look for the 50 or 57 trim t3/t4

is the t3 42/48 too small i guess? ya i don't much about turbo trim sizes but i'm learning. my goal is 250-275whp, do you think the y3/t4 57trim would be able to take me there?
I've read through the thread and theres alot of variations on power levels of people with similar setups and my knowledge isn't enough, so i want all the help I can get to get me to my goal.
