Thank you Sonny...
The compression ratio is certainly greater than 10.0:1...

Does it look that high to you Sonny ???

It kinda looks like the piston from the SEMA show two years ago? Might you have scored a set

Yeah, Like Sonny I'd say close to 12:5:1. That dome is pretty big. (Just curious)What will be the stroke?

I just wanted to post a picture of my new naturally-aspirated (yes, no JRSC for this one... heheh) budget project.

What you will see below (I guess I need to convince Sonnyballs to help first... heheh) is a big bore GSR block and the high compression JE piston at TDC sticking out the top. I have chosen to use a '00 Si head with a big pile of Crower and Ferrea valvetrain products.

Anyone wanna guess what the effective CR will be ?!?

The stroke is stock GSR... 87.2mm
The bore is 84mm (+.120")
This makes an effective displacement of 1933cc's.

Here is a hint for all those who are guessing:

The pistons are 13.0:1 GSR pistons... however, I am using a Civic Si head (which has a larger combustion chamber), so it will in fact be less.

Nice... but you need to put a gsr head instead Are you going with the crower cams too?
