I have a 2004 Dodge SRT-4.
FWD 2.4 L 4-cylinder w/ stock turbo.
Modifications include 3" catless turbo back exhaust, 3" O2 housing, short ram intake, hot/cold side hard pipes w/ HKS SSQ3 blow off valve, big front mount intercooler, solid engine and transmission mounts, walboro 225 fuel pump, AGP fuel return line kit, AGP fuel pressure regulator, 650cc injectors, MSD coil, MSD spark plug wires, Diablo Sport Trinity tuner, Mopar short throw shifter.
As soon as I get back from deployment, I'm throwing money down for an engine rebuild, tranny rebuild, new axles, new or rebuilt turbo.
I'm going to sell her all together and get my hands on a 2005 Subaru WRX. Not an STi. Just a WRX. Immediate modifcations would include a catless turbo back exhaust and a tune. Boost leak test teh hell out of her and replace the intake system (manifold, throttle body, pipes, bov, intercooler). From there it'd be anyone elses guess. Depending on the necessity of replacement and the cost of parts it could go in a million directions. Also, immediate replacement of all gaskets would occur. And I do mean ALL gaskets.
