ok i have a b20v. a friend of mine gave me a gsr block complete i was thinking of taking the crackshaft and connecting rods out of the gsr block and putting them on my b20 block with 84.5mm pistons would that work good on my set up?? my gsr head is pretty much finish i have all supertech valves springs n retainers with ctr cams.

 

that would be counter productive. going from 89mm stroke to 87.2mm stroke you will just loose tq. it will be more reliable in the upper rpms but not really worth it, sell the gsr block and buy some decent rod bolts or other parts.

 

so it will b more reliable than the b20 parts!! koo thanx! and if i go tuned it how much power would i get u think?? with a 100 shot of nitrous........

 

I used an 87.2mm ITR crank on my b20 and made 165lbs of torque. There are no issues with using the GS-R crank. Mine revs smooth as hell to 9300

 

itr better koo wat about rods??

 

Sell the B20, take money and sleeve the B18C.

 

them sleeve how much???
