I can't decide what to get. A garret t3/t4e 57 trim or 60 trim (a/r is .63). This will be on a LS (redline 6800) and I want to boost around 16psi (~300hp). Bottom is built but no sleeved. I want a turbo to not be soo laggy and to hit around full boost at 4300rpm. Which will be better and does the 57 trim and 60 trim make that big of a difference??

 

sounds like you should be getting the .48ar if you want full boost at that rpm

4300-4800 at 16psi maybe....

.48a/r is made for the ls

Didnt' you have another thread where everyone tried to explain to you that it doesn't matter the boost it takes to reach 300whp?

ya. my goal now is to hit low 300 around 16psi and then later on ill upgrade my 440cc to 550 and turn the boost up. t3/t4b wont be efficient soon so I might as well upgrade now. Just trying to figure wat turbo I should get now so later I can turn the boost up when I get more cash.

 

get the 57 trim. that's what i have and i get full boost at 4.3k. this trim is capable of doing 400+whp

.63 a/r .60 compressor .57 trim t3/t04e

Wont the 60 trim spool up faster?

 

on my t3/to4e 60 i spooled 10psi around 4400 with a mild exhaust leak. so 16 psi would be there fully (given you don't have any exhaust leaks), at around 4750.
