1998 Acura GS-R, bought w/ no motor-(stolen, recovered w/o engine, obviously) well i scored a 1997 1.8L LS motor, i am going to turbo, looking to push 325-400whp. DO I need to hone the pistons of this block to handle the stress of the boost? quoted at $1,200. I want to run 15-30 psi boost. Part #2 question: How much is a front wheel drive LSD (limited slip diff)? Can you buy a used one? This is costing ALOT more than originally expected, I mean like $5-$8 grand b-4 i go smoke wrx's(sti) and evo's, mustang's, and camaros!!!!!
