(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...

If you're running carburetors, it would be best if you were to change the cam and lifters along with changing the pistons to 96mm. If you're running EFI, you need to be aware that significant adjustments will need to be made to the FI system, and choices of effective cams are basically reduced to stock or Jake Raby's special camshaft for EFI. 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.
