i`d say add a couple of degrees of ignition timing, but with the crappy 91 octane we have, it`s not a good idea.

first one was put into the wrong area. but does it really matter?

but back on topic i was trying to find what is the most cost effective way to increase boost safely. ive come up with re machine the deck, metal head gasket, head studs, cams, adjustable cam gears and boost controller.

SUGGESTIONS AND IDEAS?

more boost = bigger turbo = later spool.
pump fuel (except e85) = low compression needed = later spool.
cams = bad VE = later spool.

Basically, more power = less throttle response. Unless you use race / e85 fuel and high comp engine, NOS or nitrometh. The last 2 are not really "safe".

I suggest you learn more about engines before spending money on yours. And be clear about your goals, because basically you cant achieve more HP and better response at the same time unless you go bigger displacement (and i mean real bigger, not a 2.2L stroker kit)

none of that will improve power or response though
and [pon-cams + 740s] = noob


[Response.... Drifting... Reliability... ]

If you can deal with an OEM turbocharger, 220-280 horsepower, you leave everything ALONE, stock turbo, stock exhaust, stock manifolds, stock cams, stock flywheel etc... and use the shortest, smallest, lightest, high quality intercooler AND plumbing possible.

There is your response, and reliability, and I believe it would also slide.
