If you tweak the E.C.U, how do you handle smog checks? and finally If I go for the pulley mod is top or bottom better (blower pulley seems a lot easier to install) and do I have to upgrade the I.C. or will the blower cutout save my engine if the charge gets too hot. THANKS JEFF
Jeff - congrats on the purchase!
Tweak the ECU - LET did mine and I can not believe the difference. #1 on the list. I would guess you would have no smog issues.
Pulley - either will work. I chose the LET bottom pully, added bonus you get rid of the cheapo factory balancer (plastic - that is known to have issues) Kill 2 birds...
Doing these two there are no IC upgrades required- there is quite a bid of info coming about the heat exchangers on here. I do not see a big benefit at this point.
Choose an upgraded intake or at least K&Ns (also watch LET they have a nice one in the works) Needswings CAI is a great performer but you loose the factory engine covers.
Exhaust - Magnaflow has a nice setup but the SRT is not a direct bolt on - a "Y" pipe needs to be made.
Have fun - I am sure you will get a lot of responses!
EDIT* Phenolic spacers..Not sure you gain much but let me tell you once you open the intake you will want to add a oil catch.
