i have a 94 gsr i was thinking of putting an ls crank and rods in my b18c1 block and putting higher cp pistons in, is it worth it or should i just stick with the gsr internals and the high cp pistons?

 

y would u do that? just change the pistons everything else is fine

 

it depends on what you want out of the car

do you want straight line acceleration, or a car that you can auto cross and rev the crap out of?

 

just makin sure i would get the rite response. i dont really think the extra 5-9 tq is worth it. if i were to keep gsr rods and crank and have them micropolished and balanced with some 11:5:1 cp pistons and a stock gsr head... would someone with a stock b20z2 block and stock gsr head still be faster? just because its a 85mm?

 

for now the car is for drag because its a mild build but after i get the right suspention i want to get into circuit racing

 

and cant a gsr crank rev faster and handle higher rpms?

 

if you plan to circuit race then use the GSR crank and rods

 

how do you feel about knife edging but using the stock crank pulley...
i know about the harmonic balance and whatnot but i just want a 2nd opinion
