(IMG:style_emoticons/default/confused24.gif) I am looking into purchasing 94mm Mahle DISHED pistons.. And I find limited info.. If I look at Mahle's on the web I see little or no product#'s. Bus 94mm Dished Pistons I can get for $300.00 and the porsche 914 94mm dished Pistons I can get for anywhere from $700 to $1300.00 They appear exactly the same except maybe the dish's CC which I get conlicting info on too.. 914 stock dish cc is either 15cc or 5cc depending where I look.. Now I am so confused that I would like to be able to identify what I can use and what is really on my car now?? Help...

Nothing has to be done to your crank for 96mm pistons. There are 2 versions of the 96mm however, one for the 1.7 and 1.8, which has something to do with the wrist pin offset (??) and another set for the 2.0. However, I don't think 96's will solve your high compression situation, you still have to figure deck height etc. and compression chamber volume to calc compression ratio. There are spacers available for the bottom on the cylinder where the cylinder base goes into the case that may be able to adjust for compression ratio. I don't know if 9:1 is too high a ratio as the euro 2L p's & c's have a 8:1 ratio (if set up for that ratio)
