Thread: SR20VE Pistons from CP Pistons ***Available Soon***

what is the difference between these and det pistons? like for example what is the difference with a ve 86mm 9:1 and a det 86 8.5:1?

Are these going to be lighter then factory pistons?

The Ve pistons at 9:1 have more dish than a 8.5:1 det piston. The 8.5:1 VE piston has a big dish.

I am all for these being made as long as they have deep valve reliefs for playing with cam timing and oversized valves. A lot of big number guys are gonna need it prob.

If I ever burn through these JEs I have now I will invest in these.

Need lightweight 87mm and 13-13.5 comp. N/A eq. full race motor.

What is everyone cranking these cam gears too?? When you say deeper, we need a better idea. The N1 cam centerline is 104 intake and 110 on exhaust. How much more/less are you going? At that centerline and oversized exhaust valve only indents a clayed piston about .080" and the intake doesn't touch. We need this feedback so the pistons will be right the first time.

Thanks,

Mark can you give me a call please. Thanks. I will give an explanation on the piston valve clearance

Making 92mm pistons for that new head gasket?

Whats the estimated time on when these will be available mark said next week in the first post? So like now...? Also i cant get on mazworxs website.

Can anyone tell me what compression ratio these 9:1 ve pistons give me with a gtir head?

The GTiR head is larger, about 48cc , which is more than the 41.8 or so of the VE, so the compression would be very low, about 6.6:1, should be able to run 50 lbs of boost?

Mike

The compression of these pistons would be about 7.9 to 1 compression
