so 140's not bad? that my comp on all 4 and it seemed kinda low compared to what its supposed to be, 195.

wtf 195 is a n/a motor 140 id say is still okay for an sr20deT a n/a motor fuck that would be low so yeah

sr20det hmm id say between 140-180 no more than maybe 5psi away from eachother

and

KA's i dont know above 180 maybe ?? and of course no more than 5 psi away from eachother either

Per fsm, sr20det compression numbers are 156 psi standard and 128 psi minimum. There can be no difference of 14 psi.

wordson07 · 03-07-2007, 07:51 PM

For ka24de per fsm, couldn't find info on ka24e, 179 psi standard and 151 psi minimum and there can be no difference of 14 psi.
