ok well my question is i wanna do ctr pistons in my b16 while i got it torn down the question i have it my head is milled 30 thousand and with the ctr piston my compression will be 12.5.1 but i worried about my clearances has anyone every tried this and i really dont wanna have to clay if i dont have to.

 

hmmm, you don't have this compression.

if mugen 0.3mm head gasket put more 0.5/1 comp. ratio.(stock is 0.7mm)

0.30mm don't give to you this compression.

if you only put the pistons, you have 11/1.
with 30 thousand you have around 11.3/1 comp.

i have ycp ctr pistons in my b16A2, with 0.10 milled block.
and the head is milled 0.30, like yours!

 

Do it, and buy my pistons.. LOL.

 

i just did the same setup. but i used .25 over ctr pistons. It runs good but the only prob. is that u have to retard the timing alittle on pump gas

 

i bought a b16 too and the ctr pistons gotta be put in but the guy i bought it from said the the compessions to high and that it might mess up my valves. i dont know what imma do. either buy stock b16 pistons or have my rods milled and put in. anyone got any options?

Where did you get these numbers? I am pretty sure stock B16 block/head with CTR's is well over 11:1.

 

zealautowerks compression calculator

If you add the head milling towards the bottom of the calculator you see that the CR is 13.2:1 with CTR pistons in a b16. The compression height on the CTR pistons is .73mm higher in addition to the large dome. I wouldn't try it without claying the motor.
