oh god. based on your post, u probably have no idea what your doing.your gonna need a manifold, intercooler, injectors, fuel management, oil lines, gauges, bov, external wastegate unless the turbo is internally gated, a stronger clutch preferably, and a long list of lil stuff here and there.
theres alot more to turboing a car then slapping onb a turbo and ur off.
pre-fabbed kits are gay. there way over priced and 9 times out of ten your limited to what u can do with them.
go to homemadeturbo.com. that site is geared to solely turboing a car. lots of good info, so u better read oll of it twice. i researched for 4 months befoe i felt i was ready to turbo my car. ive been turbod for several months now and am buildign a motor from the ground up and im learning shit still on a daily basis
