Fellas, shortly gonna start round two of mods to my car. It's a BA xr6T . What I've got- -FG xr6turbo motor whilst retaining the my old 35/40 and intake manifold etc... -mal wood opt 3+ -T56 gearbox (as of next weekend) -4inch dump 3inch xforce exhaust Unsure about cat -actuator Tune+60lb deka injectors made 272rwkw at XFT What I'm on the border of purchasing- Process west surgey with 044 Process west stage 2.3 which includes stage 2 cooler, cold side piping hot side piping plus batt relocation and CAI Now the question is, I would love to crack 500rwhp what other mods would help support this ie turbo, plenum, valve springs..?? Also what's the likelihood of the engine coping with such power levels?? Cheers
