Default how can i find out what compression are my pistons?

not sure where to ask this question but i decided to ask in FI. i bought a supercharged 98 GSR a few years back and wanted to turbo it now since i have my a turbo kit sitting in my garage from my old civic. I bought the GSR some what built with all the receipts. i was looking through the receipt and it shows that my GSR motor has ENDYN 81.5 mm pistons and the part # is BECFI 81.5. My question is does anybody know or knows where i can find out what compression are the pistons? i googled and can't find any info on the part # on the receipt. thanks in advance

email/call endyn. They have to be rollerwaves and the 81.5 is the bore size and becfi relates to a forced induction piston so it has to be one of these two

Bore Diameter Stroke Rod Length Compression Ratio Dome volume CC Pin Diameter Piston/Pin Weight (Grams) Comp. Height
81.5 mm 87.2 mm 5.433" 9.15-9.55:1 -7.6 21.0 mm 287/81 gm 1.185"

81.5 mm 87.2 mm 5.433" 9.63-10.08:1 -4.5 21.0 mm 290/81 gm 1.185"

www.theoldone.com

other than that the only way is to tear the motor down and physically measure the pistons

here's their number 817-924-9334

I plan on having them port my b16 head along with getting a set of rollerwave 13.86:1 pistons for my high compression turbo build.

You can never go wrong with any of ENDYNs products

yea, they make and offer some of the best products and services in the honda world and beyond.

They are going to be porting my head and I'm getting a 92mm billet forged b series crank from them as well as their secondary belt tensioner, modified oil pump, rollerwave pistons, a set of their valves, and maybe their girdle.

the nice part is that they are hardcore car guys that happen to run a business and offer amazing products and services. they are super nice on the phone as well and will give you any advice you need
