i belive 9.5:1 is the compression, 8.5:1 is what you can buy for the low compression setups for turbos, if your talking pistons

i think i had the right idea i just worded it wrong. all pistons should be within 10 of each other. and i think they should still be around 60.
hopefully someone with a little more knowledge will jump in here. -------------------- Former: 96 GT 5 speed (i/p/e) Fate- rear ended by mack truck

you can squirt like 2-3 drops of oil in there and the pressure will increase if you have good compression if you don't have good compression it won't increase

I'll chime in with my compression test, even though it's a 7A-FE but maybe someone will find it useful. It was 211, 210, 210, 210 before turbo, After turbo is 211, 210, 90, 210.

Present - 3rd Gen 3S-GTE: Swap in progress QUOTE (SinisterSinner @ Dec 19, 2009 - 10:52 AM)  I dont want to even think of turbos, they blow up way too often... |
