I purchased this car in October 2013 with 145k on the clock. It was bone stock but needed a new clutch. After taking care of maintenance items over the next 6 months to a year, I eventually installed an LCR 'Stage 3 Killer' 20G turbo kit with an external wastegate, Walbro 255, Fuel Injector Development 1200cc/min injectors and a stronger clutch (6-puck, sprung disc) and ran E85. Never dyno'd the car, but it likely made around 350whp at 20-22psi.  After about a year, I decided to start collecting parts for a major overhaul of the car.  My main points of focus were a built engine, a turbo kit, ditching the OEM intake manifold, overbuilding the fuel system for my power goals, converting all of my rubber vacuum hoses to AN lines and fittings, and finally, a clutch to hold the power.  I'm now running a fully-built engine with CP 9:1 pistons, Manley 'Turbo Tuff' I-Beam rods, a DCR billet oil pump, a custom oil windage tray/crank scraper/baffle setup, ARP head studs, BC Stage 3 cams, BC valvesprings and retainers, Modern Performance adjustable cam gears, a race-ported cylinder head, and other goodies. I also completely re-vamped the car's fuel system-- Walbro 450 in-tank fuel pump, -6AN feed/return lines (braided PTFE), Fuelab 6-micron fuel filter, Fuelab 1:1 regulator, Boomba fuel rail, and ID2000 injectors. All of the vacuum hoses have been replaced with braided lines and AN fittings. The intake manifold is custom and uses an MPX 62mm throttle body from an SRT4-- it's also been fully ported. The car has a modified stock pressure plate along with a 4-puck sprung disc.  There's a lot more to list, and the car will never be "finished", but it keeps me busy. :)  Update (6/19/17) - I picked up a Haltech Elite 1500 ECU with a PNP harness for the SRT4. It'll take a little bit of modifying of the harness, but it should work great. I'll post some updates when I'm finished. Hoping to be able to dyno tune the car and then make it to Street Car Takeover in Denver in mid-July.
