I was reading somewhere that you can put an F20A(?If I remember right?) crank from an older 2.0L Lude into the b series( I don't remember if it was B16 or 18, I think it was 18) and make it a 2.0L stroker. As in, a B18A or B, if memory serves. Thus making it a 2.0L LS/VTEC....or just an LS for me, if this is correct.

Any truth to this claim?

 

the old prelude motor from the 88 & 89 Si's is B20A5.

I have one of these sitting around in my garage that I've been waiting to try and see if it will work in a newer B-series block. It has a 95mm storke, which is more than the 89mm of a B18B. It should fit from what I've been told, but I want to try it first hand to see.

I will take pics when I tear the old motor apart to note any irregulairities from the old motor. The B20A5 also had the 81mm bore as well, so it should fit.

 

Bad to the bone...that is what I was reffering to, however, there IS a DOHC 2.0L from the JDM accord that I have tracked down, and I think that that crank could very well be one to work as well.

 

Yes, the JDM 2L accord is an F20A motor.
I'm not sure what that will work in - probably the F-series block...as in the F22A, F23A from the 90+ accords. It's be interesting to see if the F22/23 crank would fit....I have an old F22A aswell, I can try the crank outta that and see if it fits in the B16/B18's.
