how much power do u think i can make with the HKS GT2540 turbo kit, with FMIC, HKS headers, full HKS exhuast, ecutek (91 octane) stock 2.5 sti shortblock with 02 wrx heads, stock tranny. using 800cc injectors and walbro pump. 18psi....anywhare in the 300+???

yeah, 18 psi is not where that turbo would want to stop though, and neither would your butt dyno.

well i guess if its just a 25, you might not make as much as i was thinking... idunno i think you can get 300 since vf turbos are making 300 on any decent tune.

Wrong forum, try Factory Forced Induction.
