I’m lookin to pick up a b17a to throw in my gsr for my blown one and the seller says the compression test numbers are 170’s across the motor…I’ve read on here that stock they are supposed to be 184 across but then I see people with 200+ readings…so whats the deal???
Well in the helm’s manual it says as long as they are within a certain range of each other the actual number doesnt matter, as long as its not something extremly low. When i did my b18a monday they were 210 200 200 210. It also depends how long they spun the motor, if it was fully warmed up, and if the throttle was wide open.
midnightteg91 is pretty much right. as long as they are above 160ish and within 10psi of eachother then your alright.
