so im building a b16a2 for an all motor fun car to drive a little 1/4 mile and a little autocross and a lot of just cruising
ok now for the fun part, i want to put a lightweight crankshaft in it with new pistons ect but i was wondering if it was possible to buy a gsr or ITR crankshaft and rods and piston set because the bore is the same and to me it looks like the stroke will work but this is my first honda build and have only read online that all bseries parts fit each other and was told to ask my qustions here TY for your time

 

B16 block + GSR/ITR crank and rods = nope. The B18 block is taller than the B16 block, therefor you can't use that combo.

 

TY i couldnt find the deck hieght of the engines
where is a good place to buy an egal crankshaft and other parts im looking at importproformanceparts.net

 

B18 block is .354" taller IIRC.

I would check the marketplace if I were you.
