well how much HP you plan? How much boost on a GT28 do you plan? Your end goals will help us help you.
end goals usually go as deep as the pockets.

went to max out the gt25 first
im really only thinking about 12-14psi, aiming for 250whp, went to max out the gt25 first since cash well disappear fast on internals, and than ill go with a gt28r hopefully,
id probably recommend 9:1, maybe with a thick headgasket. that seems like the happy medium, 8.5 is overkill unless youre aiming for well over 300whp.just an update for all you people, finally got my other motor home, on the engine stand, head is off it, cylinder walls look GREAT! and the intake manifold had VTCS AND VICS deleted weird lol, but i well soon be starting to build, my k1 rods are ordered, ordering my wiseco pistions probably after christmas, i deciede to go with the 9:1 ratio so far, might change my mind, well have some more pics up soon, and a few more posts once i take the stock pistons out of my new block.
