I'm trying to figure out my compression ratio
Using this C/R Calc ---> http://www.summitracing.com/expertad...sionCalculator
I'm not sure what to put for my
(Deck Clearance) and (Compressed Gasket Thickness)
Engine is 2001 B18C1
Here is what I have for the other
Bore: (diameter) 81.5mm
Stroke: 87.2mm
Cylinder Head Volume: 41.6cc
Effective Dome Volume: +7.70cc
Deck Clearance: ???????
Compressed Gasket Thickness: ??????
Number of Cylinders: 4
Here are the pistons I'm looking to use.

Not that there is anything wrong with what you are doing, but ordering engine internals for your Honda from Summit is kinda
CP, Wiseco, Arias, Manley, JE all make good pistons for your car.

Re: I'm trying to figure out my compression ratio
Without knowing what turbo I cant really help you, on a GSR typically yes unless your running something really small.

You're gonna hate that eBay turbo. Not to mention it has a t04b wheel so it's gonna make shitty power.

Re: I'm trying to figure out my compression ratio
How about this turbo? Will this be too big for a daily driver?

Re: I'm trying to figure out my compression ratio
Ya its mine. Its a billet 6262. It has a .82 a/r exhaust and a .70 a/r compressor cover. Its rated to the 700whp range, but I know alot of ppl who have made 750-800 on them. This will not be a effecient turbo for your setup. The powerband will be useless.

Re: I'm trying to figure out my compression ratio
if you smooth the chamber you'll have more than 41.6ccs also depends on what valves you use. personally i'm all about oem or ferrera.
piston wise, i really don't see a reason to build a 9:1 street engine
if you use the ferrera dished valves and shave the deck and block to being true along with an oem head gasket you should fall right around 10:1-1 to 10:5-1 with the below piston, it really all depends on how you work the combustion chamber and how much winds up being shaved
