I was planning to get 4g63, VW golf gti or BMW ones as they are cheap to get compared to the nissan ones.

That would be very interesting! especially with 200cc+ extra 88mm stroke.

I would love the longer rods as they work best with these horrible shallow port design and the ca20e block can go to 85.5mm bores with ease as they are cast as 84.5mm and can take 2mm more with ease and proven with boost.

The full counterweight cd20 crank Ive got only accepts the ca18det oil pump and Ill be using either 85 or 86 mm pistons first have to do some sonic testing and x-raying of the bores. Id prefer 85mm for extra wall thickness.
