i have large grs i/c which i will be fitting soon, im also running a standard turbo at the moment with a stage 3 head,cvh34 cam, standard bottom end with arp bolts, i want to have the safest power band out of the current engine, is it worth having a stage 3 turbo also fitted with the the grs?

 

what power do you want, and what rpm do you want to be using?

 

will be keeping the setup above but with standard rods, so im only looking to get 230 max if possible, not to sure what rpm the stage 3 starts to kick in so some advice would be helpful.

 

never driven a Stg3 RST, but i run a cossie T3 on my Xr2tt, and it will be the same on spool.


looking @ 3500 rpm for full boost, 250bhp ish max.

 

my stg 3 t3 was on full boost by 2800rpm

 

Matters what you call full boost?


my 4wd cos T3 hits 20psi by 3000, and 28psi by 3400 ish rpm.
