ok heres the question, can i put a b20 crank into a b18 block to increase the stroke of the motor ??? im having the block sent to benson so i can get it sleeved to 82mm and i have wiseco pistons that are 9.2 to 1...... would this be possible or would there be a lot of extra machining needed for the crank to clear......honda tunings new issue is about turning a b16 into a 2liter by putting an ls crank, and 85mm pistons in it, so i got to thinking, since right now im running a lsvtec and i have a full turbo setup sitting in my room, ( dont want to boost untill i have a built motor) why dont i just build a sleeved b20 or b18 stroker w/ b20 crank to achieve b20 the b20 stroke....... it would have more torque than an lsvtec although neither motors like to rev very high.... i just need some input from people who know what there talkin about.....

 

If your talking about the B18a/b and b20 motors, they both have the same stroke(89mm)...

Youll have to go with a custom crank and rods if you want to stroke it anymore...92mm is next then 94 and 95mm...I know Crower,Scat,and Eagle all make kits...
I say get it sleeved and bore it to 84mm. Youll get more displacement/torque and it wont hurt your rod ratio...
Theres only so much you can get out of the B series. I think its around 2.2 without a deckplate...
