F20B Crankshaft in an H-Series motor?

[dakilla4ever]

I've heard plenty rumors but I figured someone on here would now the real answer. Will an F20B S2000 crankshaft and connecting rods work in an H-Series motor? I've heard that people have done it and easily spun the motor up to 9000 rpm's. Please enlighten me. If this is true I wouldn't mind trying it.

the thing to do is a f20b block with f23 crank and f23 rods with k20 pistons (f20b has the 95mm mains just like the f23 which has 95mm mains and 97mm stroke... the f20b block is stock 85mm cast iron sleeves... you bore it out to 86mm and fit the stock k20 pistons in it and you are ridin). similar setup with cut down h22 pistons on h-t made 255 whp

dakiller it's f20c. f20b came in an accord. I'm pretty sure you can get the new f22c (newest s2k) crank to work seeing that it's the same bore and stroke as the h22.


I think you would have to run the s2k's rods as well seeing that they are made a little stronger.

i just read the topic again and overlooked something. F20b is accord euro-r, f20c is s2000 00-03. f22c is s2000 04-current. F20b is pretty much a destroked h22a, the heads are the same. but as for as the block if you need more info check out accordinglydone.com
