hello to all you sr20 gurus!
Im trying to get my car ready for the dyno.
I was doing some final checks over my engine and I just wanted to make sure I dont have a BIG problem before I strap on to the dyno and get tuned.
My compression readings are kinda low I think. I dont have an fsm for the sr,
but the one I have for the ka'd 89 240sx says lowest is supposed to be 149psi with a difference of 14psi/300 rpms.
number 1

number 4

As you can see, my numbers are above that, but just barely. I just lookin for some insight from all of you that have done tunes in the past.
Will i be able to get a solid tune with these numbers,
or should I say fuck it and rebuild?
I have a s13 redtop
stock bottom end
stage 1 cams +valve springs
freddy intake w, N14 TB
555 nismos
stock turbo
full exhaust + test pipe
hard pipes and front mount
Thank you guys for your time.
