what is the psi at cylinders ?

is it at 180 all the way or do i have bad piston rings ? i have 150.149.149.150 so can any one help ? what should i do replace the ring or swap motor an sr 20det? an if so swap it then ill sell it so i can have extra money 4 sr20det help please

well there are a few possibilties

worn rings are one reason, however you could have worn valves or valve seats

do a cyl leak down test and if at all possible hook up shop air to the cyls and see if you can hear where it is leaking from

they told me that its the piston ring s and they did the comp test so they told me that u might as well swap ka24de or just sr20det it what do u recommened ?

your comp seems pretty normal to me, as long as it doesnt drop past 120 you are good.

THose are great compression results.

if u fellas dont mind then what happens is that when i took it for a test drive an rode it when the vaccum hoses were not attached to the thing where they go to i dont have a air filter or a breather attached either but no check engine light on but the car dies what s up with that i know that i am going to get a battery new one from optima red or yellow top ? what do u guys recomend ? die hard interstate ? do u guys think that its the battery ?can any one help

put an air filter on and attatch the vac hoses, no engine will run right with them off.

HAHHAHAHHAHAHAHHAHAHAHHAHAHAHHHAHAHAHAHAHHAHAHAHAHAHH
AHAHAHAHAHHAHAHAHAHAHAHHAHAHHAHAHHAHAHAHAHHAHAHAHAHAH
AHHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAH.
WHy would you start at the battery??? THeres like absolutely no correlation between that and cylinder compression.

Nah man, it isnt your battery. The vacuums being disconnected would make it idle like shit and shutoff, Also the fact that you have no air filter on means that your intake air temperature is probably hanging out into nowhere, which would also make it die.
You should read some mechanic books or some shit man.

+1 you're fine dude.

and like everyone said. connect your vaccum hoses. car will run like crap without them. take your time, make sure everythings right.

the hoses r pluged up with rubber caps ,do u think even with those on it would still do that problem ? ill get a cone filter from apc . i heard that they just recently got a steel mesh kind ill go an buy that ill see what can i do but like put an air filter on and attatch the vac hoses, no engine will run right with them off. = right. my comp seems pretty normal to me, as long as it doesnt drop past 120 you are good. that what amd240 said .

try again grasshopper

man u guy are the best ohh yeahhh when the car is done beer is on me. thankz guys

^just do that.

i'll take a miller lite

OKAY..........

wow i'm glad i took a road trip rather then sitting here trying to figure out WTF he just said....

it's to early for this, cliffnotes?

cliffnotes: 1) wants to know if 150 149 149 150 is good compression.
2) wants to know if car will run right without any vaccum lines connected.
