[btimola]

Hi guys, first z. Always liked them. I wanted a gtr but too hard to find a good used one. Ive owned like 7 vws all turbo and the z is definately lacking. I cant drive a non turbo doesnt feel right anymore. Anyways its a 2009 touring sport. Has an exhaust already. Got it for 20k w 3yr warranty.

I have a friend who has an 09 as well. His is stillen supercharged. Has navigation, a custom sub and box, suspension, header, etc. Hes repoing it this week or so. He pays 690 a month! I pay half what he does with a warranty! Anyways, hes willing to sell me the full charger in exchange for my oem parts. Before the bank takes it. 3,000 for the charger, injectors, pump, etc, sub, box, amp, header. Wed go halfs on the install which is only 600. However, i called stillen and they said id need to gonto uprev to tune it. Its 900 bucks and an 8hr drive round trip and id need to tow the car there. Is there a way to just swap ecus? Or would the keys and car trip out? Please help id really want it its very cheap at that price. Also it already has 25k miles on the charger, do they last? Thanx, also how bout the navi is it hard to swap for the regular bose unit?
