So after having this z22 sit in my garage I am going to start playing with it. It is out of a 720 that I swapped a ka24e into and got rid of a few years ago unsure of what car/truck it is going to go in at the moment thinking of finding a single cab rwd 720 for it (will need to go south to get one they rust to pieces up here) or a d21 that came with a z24i. Really just wanting to learn a bit while I mess up I mean rebuild this engine . Parts for it are cheap (compared to an rb26dett ) and seems to be a decent amount of info out there on them. Will be the first time measuring bearing clearances and such. The farthest I have been into an engine is replacing the shortblock on my subaru (fucking ej20s and their rod bearings).
So far the plans are:
z22 bottom end/head
ka24e truck pistons
cast iron ka24e ported to somewhat match z22 exhaust ports
z24i distributor for a trigger
z20e intake manifold
z24 head gasket
things I am still researching are:
ka24 piston-valve clearance in a z22 (some posts seem to say the pistons will need reliefs but that may just be for bigger cams?)
higher capacity oil pump
turbo (have an old turbo off my rb26dett that may work if not maybe an rb20 turbo as they are dirt cheap and plentiful)
boost/power goals thinking somewhere between 5-10psi would like to see 150whp would be over a 100% increase in power so might be a bit lofty
rod/head bolts? L20B arp rod bolts most likely unsure if they will work will need to measure the ones I pulled out and see if I can find the specs on the l20b ones. I believe they take the same rods so may be in luck. Not too sure for head bolts they seemed quite tiny compared to the arp studs I used in my ej20k but they are also not going into an aluminum block.
Still lots to read into, if anyone has done this before would love to hear from them.
