I have a 1974 2.0 with Reman Heads that are getting cc'd. Upon futher investigation it turns out I have VW Bus Pistons. I would like to put New Stock 914 Pistons in to replace these. I understand compresion math and deck hieght, shimming etc.. But would like to know what do I need to do Mechanically to do the swap without causing me more problems than I started with.. Car has run really well and is only getting reman heads because of a broken chunk with helicoil attached came off with exhaust hanging stud... Suposedley the car engine was rebuilt 8000 miles ago but i do not know the extent nor do I beleive anything I was told when I bought the car anymore though I do not think I was lied too just a differ of what is restored and what is rebuilt.. I would like to get away with the minumum right now and crack the case later when I am more edjucated and know better what I want out of my engine.. Stock is fine with me now and may stay that way but would hate to rebuild a car that runs well ..spend a lot more money getting it stock rebuilt only next year to decided i want more power or torque..

What is the respectable safe minumum to a Piston Swap like this..

"If you replace your existing pistons, be aware that you need to have the rods reconditioned and the new wristpins fitted to the small ends."

The good Dr gives sage advice but I would look into getting 96mm pistons for 2 reasons; I think they cost less than Euro piston sets and they are one of the first installations when 914 owners want more power. You are looking into installing a different set anyway, while you're in there ... (DW)

I agree w/ the DR. and your logic has truth too, but so far everything I have done to the car has been towards stock w/ often new for reliabilty or slight improvement. I would hate to change that around now and would also not want to half step a power modification especially with more money involved and my limited experience at this time.. I do not think I am ready plus if I drive it stock for awhile (year or two) then maybe I could appreciate further changes even more so as I would know the differnece..
