 #mpact prep for some fresh (and fast) E36 and E46 M3's  Part out or more mods?
 Anyone looking for a 450+whp turbo E36 for the price of a turbo kit and install? $10k firm, Custom kit, TT 60# software. 95 325 chassis, OBD2 2.8 motor. M3 subframes, trans, diff, etc. Coilovers, upgraded sway bars and rear chassis brace. New clutch. New 3" SS exhaust. Newer trans. Full m3 black interior and exterior parts. Car is a fun driver as it sits. Saggy headliner, currently not set up for ac. With paint correction and some minimal effort it can be a really nice car.  Nice dyno comparison of stock, Dinan piggyback, and BM3 stage 1 flash. Mods are Dinan exhaust, intercoolers, intakes for all runs. Dyno runs done in 4th gear, linked AWD. Rwd should see even higher numbers.
