I just did a compression test on my 94 GSR, turbo'd. Got 210psi on the outers, 170+ on the two inner cylinders. Dropped some oil in, got 270psi across the board. So it looks like rings are bad. I have a dyno scheduled in 2 weeks at Church automotive for my Hondata install. I can't build it until next summer. Should I tune it anyway? Or stay FMU and keep the boost down for a while? Thanks for the input.

On the upside, I just put on 3" downpipe back custom exhaust w/3" Magnaflow muffler and flexpipe! Sounds pretty nice, spools nice.

if you want that motor to last till next summer, dont boost it, put it back to stock. Boosting it will make it worse.

DON'T waste your money tuning it now.

FIX the engine then tune it....

You can do what mase said and go back to stock, or add 20w-50 and some tuning just for saftey until the rebuild.

If it would last till summer, I should be able to afford a complete buildup--sleeved, rods, head, etc. Right now, I'm tapped. The motor has 138,000 miles, been boosted for a while. I don't know how long bad rings last. I have Hondata and 440's to put in, just need a tune to make work. I wonder if I could just use a base map to get by? If the cylinder walls aren't too bad, how much would just rings be to get me by? I can take the head off, I just don't do internal work.
