Ya ive been reading alot about F/I. and how the turbine works in conjunction with the engines exhaust and then the compression of air into the engine. air/fuel ratios arent really the big problem, I am an A student in ap chem, all i cant really yet understand is the compression that a motor can take with the pistons and how it changes with which pistons and the max the motor can then take along with the min. Then i dont know which turbo to use and what piping to use.

The turbo issue of super street 2002 with the gold supra on front .......8 stupid questions about turbo's ........Pretty much tells ya what questions to ask so no-one asks you a question about your question......(NOT A SUPER STREET FAN)

The B18b is just a 94 up LS the B18a is the same head and block just some better cams and shit like that, ten more Whp in the B18b vs.B18a.......JMO

it really depends on what the b18c1 was built for. i mean yousa y built, but is it built for high compression or low compression. before you buy it, you got make sure what the original intent that the previous owner built it up for, ya know? stock for stock... a b18b has lower compression and is better for boosting.
