Hi there guys! Love all the discussions and help thats been happening here.

Just would like to know I want to convert my B18c1 (GSR) to B20, but i got a few questions.

1. Do i need to bore my engine block to bigger size? Bore as in widening the holes for the pistons right?

2. 84mm 95mm 2.10L is the specifications from crower.com storker kits. I want to change my cams to type 3 Jun cams, would it fit? (the valve clearance) I think i read somewhere that the pistons might hit the valves cos of clearance problems.

1st 2nd 3rd

Duration|lift Duration|lift Duration|lift|Vc
Type3 INT 60 (240) 6.5|76 (304) 12.0|63 (252) 9.0 0.17 1004M-H003
EXH 63 (252) 8.7 76 (304) 11.5 60 (240) 6.2 0.19 1004M-H103

If anyone has the knowledge please help me out!! I wonder has anyone done this b4.. I hope to build a powerful B-series engine.

 

id say stay away from stroker kits. if you want more cc's, take your b18c and get it resleeved and bored to 85mm. youll need new pistons, and rods for them to go on. forged pistons dont fit stock rods w/o a machine shop.

 

New pistons? how about standard 2ltr crv pistons? with aftermarket rods? would this do the trick?

 

nickgmiller04 thanks for your great advice! Im sort of a newbie at this ... maybe i will think abt it and research somemore and ask u again later... hehehe
