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?!... |
as far as im aware the Ca20 wasnt done as a turbo (et suffix) only N/A with e suffix. ive heard the cranks arent as tough as CA18ET cranks either (unusally tough for a OEM engine crank spec). wouldnt mind looking into buying a couple undamaged of Ca20 cranks if you can get them though and shipping them over?
Bren from Apex performance has had some custom 2litre cranks made for the DETs, but around £1200 each iirc they are also 8 stud fitting for the flywheel and need the DET oil pump & sump and youd need to have the bottom timing belt pulley modified to fit the larger DET crank nose diameter, but all do-able if ya doing a serious build
