From reading/lurking here, it seems as though ASP pulley and ECU tune seems to be the big thing. What about K&N filters? Or a larger exhaust?
Over Drive Pulley System - (ASP, EVO, Renntech) - Biggest Gain
SL55 Intake Y-pipe - Modest gain
K&N - Modest gain
Iridium Spark Plugs - Modest gain
The ASP Pulley / ECU Tune is a least expensive ODPS ($1,400). Renntech and EVO offer matched pulley/tune upgrades but cost more. ($2,800 - $3,400).
There are no real exhaust upgrades that produce measurable power only more sound. No A/M headers but I read a thread on the forum where someone had a custom header set built for around $2,800.
Internal engine components if you want to really wrench and spend.
How fast do you want to go and how much are you willing to spend are your only limitations.
