#355614 here is the update on the engine. I have found that the 75mm vitaras are slightly smaller overall as the pictures below will show. 2.953 is the factory piston. Vitaras run 2.946-8 this is out of tolerance as it needs to be within .002 from what I read. this also may be enhanced with it being a lightly warn cylinder. you can also see that the dome side is smaller as well. 2.926 (vitara) 2.935 factory. luckily I have a few lines in my cylinders but no grooves. I plan on putting in 75mm srp's at this point after I verify that the bore has not been affected by the pistons.

keep in mind I measured and re-measured several times and the measurements were not the same all the time but they were consistently smaller for the 75mm vitaras.

#355619 Good, at least the wear on the block was minimal. Hopefully just the new pistons will be all you need to be on your way to boost. :thumb:
