sorry, numbers mixed up but I figure I had around 9:1, head was shaved alot, so guess I was around 9.5:1.

My spare 89 turbo block had 86 tbi pistons and LW rods.

the van has become my daily driver, and its a 2.5 tbi block with a g head on it, im figuring about 8.7:1 ? Its running a mitsu, large IC, and 13 psi fine.
