haha any shop will do it. Why are you checking it? Otherwise princess auto sells leak down testers and pressure gages.Than as someone already sad take 1 spark plug out at the time , screw the tester in the hole, crank the car for 2-3 sec with dizzy disconected. Add few drops of oil and re-crank , record pressure, move to next cylinder.Once all done reconect dizzy. ---

And don’t forget that the compressions should be consistent if you are planning on turboing. If you have 1 cylinder thats at 160psi and another thats at 180psi, its probably not going to be a safe set-up. They shouldn’t differ more than ~5psi. ---

Don’t get the gr kit . Just order parts 1 by 1etc just like everyone on ka-t does. Or if you want a kit get AMS JGS ets. And who cares what ur comp is,just blow it ip first if its shiety. Afterwards you can get another ka for cheap anyway than look for one with good comp etc. ---

i thought +/- 20psi between cylinders was the limit for a turbo setup… +/- 5psi would be amazing, and somewhat rare on higher mileage rings & seals ---

I had a 5psi difference on my KA24DE with 220k on it. If you have a 20psi difference on the 4 cylinders you are going to have more to worry about than turbo’ing it. ---

My SR was about 3 psi off between highest and lowest cylinder The FSM states + or - 20 PSI but i would not recomend over 10 and 5 is great ---

If your going to take it to a shop make sure they do both a leakdown and compression test. [Next page](https://forums.speedlife.net/t/compression-test/146147.md?page=2)
