which is better in terms of spool times, effeciency for my z6?

 

What year of T-bird? There are two competely different turbos for the t-bird. IHI or T3?

Also, screw spool time, Low Spool time means low power!!!!!!

 

well i got a extra z6 motor stock... im gonna be running somewhere beteween 10-14psi of boost prolly start at 10 then go up, even though i have been told 7 is max on stock internals, i've read around and ppl on here are running up to 14. i was just wandering which is best for this application, i want to achieve 200-230hp with all my stock ----, porlly will be acquiring a new clutch too, mines awful screwy

 

With a good tune 12+psi won't be needed for 200whp. The 14b might run ou of huff a little up top at the psi. Need to know what year of T-bird to mke a jdgement call on that one. an '84 would be WAY better then an '87 though. T3 vs IHI.

7 is not max on stock internals, not by a long shot unless you can't tune worth a ----!

 

Yeah you don't want anything off of a t-bird from 87/88, they switched to smaller ihi turbos.

 

so then 87-under 2.3 turbo then a 14b then a ihi? in that order i know i can get that t3 turbo from my teacher erally cheap... was just wandering ty

Get the t3. even if it's nt from a t-bird, it better then an IHI or a 14b. More popular and easy towork with.

 

t3 hands down
u can upgrade
more support
better turbo

 

t3 60/63 will have the highest spool time and biggest top end, a .48 will have better spool at some expense of the top end but it should be faster than a 14b, even though the 14b is a good choice also
