i have a small rear mount 60-1 behind my LQ4/T56. it gets to full boost at 3K. i want to get a bigger turbo but i know it will take more time to spool up. i will be setting it at 14psi w/meth. i was thinking between the 67 and the t70. i wanted to get a t76 but when should i get full boost around these bigger turbos or would it be better to ditch the sts and get something else.

 

ditch the STS.

 

Get a KBRacing front mount and go with the t70. What A/R you got on the exhaust side now?

 

two small twins, or a TVS.

 

I would step up to atleast a 70mm or go with a front mount

 

i contacted kbracing and i think im gonna do it, i think a t76 up FRONT w/quick spool valve should really help.

 

Get a 2-step too, so you can launch with some boost. :jugde:

 

wtf is a quick spool valve?

my mpt 70 spools very quick on my 6l front mount, don't think you'd make 14psi with one though. I've ran mine up to 13.5, but even at 12 the intake temps start to climb hard.
