Would you consider 215 210 210 215 good numbers for a jdm type r? or would you consider that low?

 

i think they are suppose to be around 260 or 275 if i remember correctly. could be wrong tho.

 

negative. those numbers are fine. you're good to go.

 

ok. when i rebuilt mine a thought i had seen those numbers on a spec listing. sorry for wrong info. mine still came out a lil more than 215 tho. mine varied from 225 to 235. but i guess you wont see much of a difference in that anyways.

 

Listen to him, this is how he makes his living and deff knows what he is talking about.

 

 

x1 trust me im not trying to feed him bs.

 

well, compression number are affected by many many things.
-if you do it with throttle open/closed
-motor cold/warm
-if your motor has valve seals leaking/not
-gauge brand even makes a difference

All in all the most important thing about a compression test is the continuity across all cylinders. 10-15 variance is ok. more than that is worth continuing onto a leakdown test.

 

I'd seen something like that also.... I think its what they're at when they're brand new...

I always saw a little more than that even on my GSR... but like others have said, there's lots of variables to explain it...

 

Thanks yall..For all the feedback an info
