i'm not to good with calculating numbers. so i need a little help.

the engine is a B20Z

84.5mm cylinder bores
Stock 3 layer headgasket
rod to stroke ratio is 1.539
46.2cc cylinder head chambers
customs JE pistions with a compression height of 1.181
dome height .120

if someone can take the time and figure out what the static CR would be in this engine i would really appreciate it. and try to be as accurate as possible if you can.

thanks

 

anyone?

 

i need the actual displacement of the piston.. unfortunately dome and compression height won't give it to me.. you'll need to cc it.. or you could try callin je and see if they know the volume.. also you'll need the deck clearance (how deep the piston sits in the hole).. i can use the stock deck clearance to give you a general idea but without the exact number the result i come up with won't be perfect..

 

thanks......i'll try to find out the rest of the specs.
