Im tring to put together a all motor B18a non vtec crx and i want it to run on pump gas what kind of comp ratio u think id have?and do u think it will work?
You guys are the fisrt people id trust with my motor.

B18a Motor
Ctr Pistons
Eagle H Beam Rods
Blanced Crank
Crower 404 Cams
Crower DUAL SPRING & TI RETAINERS
mild p&p
head milled .20

 

if the head and block are not milled then you should be around 11.4:1 which is perfectly fine on pump gas with tuning.

this is according to c-speed racing compression calculator.

Take your time and check everything at least 20 times to be sure everything is all good. plastigauge all the bearing clearances.
