Been there, done that. :duh:
Much better to get boost manageable and get your timing and MIVEC in a good spot. I dropped 1-2psi and gained a considerable amount of torque and boost control over running the higher boost. Hot air is well, hot air. :shades:
Pretty much... all that happens is your manifold temps go up since the intercooler is air to air and will only cool so much even if very efficient it will eventually heatsoak... Generally 28 psi peak is about the limit for the turbo... MIVEC,timing,fuel provide better gains in the HP area. Boost is great for torque numbers.
Any larger turbo just flows cooler than the stocker and produces more power...
Granted in higher elevations you can run a bit more boost since air is less dense... but there is still a limit.
I see it point less. Then to get...
UICP - response
3 Port - Boost management
TP - exhaust flow
CBE - exhaust flow
Intake - smoother flow / volume.
With those you max the stock turbo. I seen the range from 5000-6500 rpm. Depending on bolt on's.
Really at point no point wasting money on bolt-ons. Better to save for a larger turbo. Will gain more benefits. Then adding DP, Piping, Larger Intake, Intercooler, WGA, etc...
Can't make chicken salad out of chicken shit... once you are out of flow there is no magical way to get more...
