120 - 140KW b18cr

Is the kit available for purchase? It's probably a huge rip off anyway. I'm sure another company would make a kit for it too

Toda make that kit fitted to the mugen car.

Also as far as bore and stroke increases, via sleeves and crank, it can all be done, B series can go 86 x 95 if displacement is what you're after.
