this was gunna be the build in my 4dr but i went with a Z6 instead... but yeah you can just get pistons and rods made for any model d16 engine.... the same goes for the Turbo manifold... the sleeves on those are actually slightly thicker than the SOHC's, I've seen several ppl post the block and run over 15 psi without cracking the sleeves... not saying you should ... but, with proper tuning it can be done... the only downside for me was that they come with composite headgaskets and with the boost i was planning on running i would've rather had a multi-layered steel one... cometic offers one, but it's for a 76mm bore... but you could have them make you one for stock bore or bore the cylinders... also, webcamshafts, gude, and i think exospeed offer cams for the ZC...
