As far as i know, et and 20 pistons and rods are the same, the CA20 gets its extra capacity due to a longer stroke on the crank! hence, if someone ever wanted to build a serious ET or DET with a 2.0 capacity, use a CA20et crank!!!
Rare as rocking horse s**t to find and wicked expensive but the only job for some serious ponies!!!
Norris designs supply a stroker kit with this crank off the shelf, but u need a big fat wallet!!!
CA18DET rods and pistons would still make your CA20 bottom end stronger if your trying to get as much power as possible from it and a cheap upgrade! i can sort you out with a set if your stuck mate!
BTW, Any chance of findn me a ca20 inlet manifold bud?!...
