the compression calcs say that this will give about 11.5:1 CR

anyone tried it?

i searched and found nothing!

 

Well, US market B16 pistons in a B18C1 after having the head resurfaced usually come to about 11.6:1. It works great actually.

 

anyone know what the c/r would be with ctr pictons in a b18c1? otherwise, those b16 looks alright in there.

 

i use:

and
http://www.c-speedracing.com/h...c.php

to work out compression ratios...

Kendall - cheers, also do you know if the wrist pin etc is the same?

Personally, I'd rather be using the PR3/P30 pistons and a head that flows like hell as opposed to using PCT's at all.

Rings and wrist pins are indeed the same.

 

those are some nice site but em... what code are for the ctr pistons?

 

teh c-speed site has the codes:

whoa! over 13:1 with the ctr pistons in the gsr head/block. i don't think that would be cool. anybody tried this on regular pump gas?

 

i doubt there would be any point using cast PCTs with a 13:1 set up - you would spend some extra bucks on some forgies

 

I think u have to use b18 rods for the b16 pistons, because the deck height is different.
