I'm only looking to rev to about 8500-8700, and I want to stay somewhere in the 9.5:1 - 10.5:1 compression range. The only thing is, it has to be somewhat reliable....

I've read up on the B16 rod/1G-GTE pistons, but the compression ratio is pretty low, and it would be even worse on the ZC... I was wondering if anyone had any specs on a non-turbo Supra piston... I like this idea because of the shorter rod length (which is compensated by the Supra piston). I know I wouldn't be able to get too crazy with compression ratio with this setup though.

I think my best bet would be to just get some H beams or other lightweight rods with the stock ZC pistons and the Y8 headgasket. My only concern is, would this be efficient? I know the aftermarket rods are built to be stronger, but it just bugs me to have a relatively "heavy" piston on top of the lightweight rod. It just seems to me that it would be hard to balance the bottom end like that...

Anyone have any ideas, or could you even make it through the babbling? TIA

 

the bad thing about ZC engine is there isnt alot of aftermarket parts available for it.
to be able to rev that high , you really need to get the bottom end balanced, blueprinted properly , proper rods and piston etc.
Stock ZC twin cam is save to be rev to 7800rpm.
