(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...

The Bus pistons have a larger dish which is in large part responsible for their low compression ratio. The US-spec 914 pistons have a smaller dish. Some old European 914 pistons have a dish that's smaller yet, while most of the ones we find now have flat tops.
The Bus pistons are likely cheaper because there are more Buses out there than 2.0 914s that people want to keep the stock displacement and compression ratio on. Also likely because the vehicles they are going into have a "VW" on the front... --DD |

Thought was that my heads are cut to a higher compression and maybe that would be a way of lowering it? I do not have any number to work with.. Then I when I found out these pistons pricing difference is so extreme I thought maybe there was something I was missing.. Thank you for confirming it.. Porsche Shops get $130.00 an hour VW shops get $90.00.. Kinda Of a CRUX for the halfbreed.. 914 pistons 1300.00 VW pistons 400.00 diference?? 10cc's.. Thats about $90.00 a Cubic Centimeter!! Following that Math and Marketing.. A 1971 displacement would cost $177,390.00. VW BUGATI shops get $300.00 an hour same as a Brain Surgeon.. I do not need a brain surgery to figure out what is going on!! |
