I finally bought a compression tester the other day, and got results for all four cylinders. Cylinders 1-4 all check out very consistent and even all the way across, maintaining around 180-185psi after several cranks of the piston reaching TDC. My battery isn't the greatest so it may not have been cranking at enogh RPM's to see proper results.
For reference, I wanted to get a little compression comparison going on so that I can get an idea of what people with healthy 5S's are running. I'm doing these checks to determine whether or not to lightly boost what I already have or to go for a newer 5SFE before the project begins. Post up figures if you have them, otherwise let me know what you think of mine and what route I should take with the motor. -------------------- 3rd gen ST205 3SGTE - Alive and boosting. |

tons of info on leak down testing
http://www.google.com/search?hl=en&q=leak+...G=Google+Search at 180,000 miles.... thats a lot of wear on the motor. it probably wont last long under boost, even even if your comp/leak down tests are good. if you do decide to boost it, have a backup motor handy (or at least plans to buy one). if your cool with the idea of having to replace the motor in a weekend then go ahead and boost it and see where it takes you. you have another daily driver now, so nows a good time to experiment with your car and see what type of power it can make. -------------------- 15PSI - 30MPG - Megasquirt Tuned
