So what is the journal size of the B230 rods. I know the B20/21 and early B23 mains are 55mm, and from '88 or so, they changed to the larger 63mm main bearings. I dont have any info on the big end sizes, but you say the B230 has smaller big end journals? So one could (off-center?) grind a stock B20 crank to a smaller size and fit B230 conrods? Is that what you mean?
If so: are the B230 conrods shorter (center-to-center) to be able to use the stock B20 24mm whrist pin pistons? Or would you need special shorter compression pistons (which would then be 2.5mm shorter)? (or is the whrist pin size different to start with?)
I've been looking into stroking a B20, so I'm eager to find out. All info would be appreciated!

Cheer, Ben
