i'm in the process of piecing together a turbo kit for my 91 ls.
i did a compression test tonight and i wanted to make sure i did everything right.......
here is the procedure i followed;
1. removed all spark plugs
2. unplugged fuel pump(so cylinders wouldn't fill with fuel)
3. hooked up tester.
4. pushed gas pedal to the floor, pressed clutch in and cranked car
5. continued to crank until pressure stopped rising(4-6 cranks)
6. repeated for each cylinder

heres my results;

cyl. 1 215
cyl. 2 210
cyl. 3 200
cyl. 4 220

these seem great considering my car has 127k.

did i do everything right? if so boost here i come!!

i thought it seemed a little high to but i think i did everything right. my car does smoke, but mostlly on start up. i thinking valve seals. it uses about a qt every 1k. motor feels and runs strong though.
other thoughts?

thanx

Those sound pretty high. I have a b18b, 110,000 miles, burn about a quart every 1,000 miles, and the copression results were: 200, 185, 180, 200.
