I have been reading a LOT of rebuild and mods on here and I was just hoping to check in w/ the experts on what I am thinking of doing. My engine has been giving me trouble (oil in the cylinder). I thought it was likely valve stem seals and that was not it. I had the head looked at professionally. I thought about buying a used engine from someone on here too, which is still an option. But, knowing that my head is good I am thinking of rebuilding the short block now.
I already have put on:
- New fuel pump and carb
- New water pump
- New timing chain and tensioner
I am thinking about having the block bored to accept either:
- OGTS 2.0L pistons: https://www.opelgtsource.com/search/2788/details - the 1.9L Pistons are out of stock online at least
- Wossner Forged Pistons https://www.ebay.com/itm/Wossner-For...wAAOSwHaBWi9HE
I am also going to have the rods reconditioned and the crank turned, if needed. I will install all new bearings and new freeze plugs.
So my question is... are there any other modifications required to install 2.0L pistons in a 1.9 block with stock crank, head, cam, etc? Such as, will the wrist pin fit, valve clearance, etc?
