Re: pistons

[Bruce Bell <bbell@csn.org>]

I don't have a direct source for pistons. And I can't attest to quality or
longevity of any manufacurers pistons. When I talked to Ron at Ron's parts
about my idea of using the Eurovan crank (fall '84) his first thought was
that pistons could be the major problem. I suggested the pistons he and
other tuners were using in their 2.0 litre VW's with the 94.5mm stroke.
Milling 0.5mm from the tops would not be a problem. It is possible that
there is enough deck clearence that nothing has to come off the top of the
piston. In that case static compression on a 10V would be about 10.7:1. I
know that Tectonics used to sell these pistons in 10:1 and 8.5:1
configurations. I've heard that Tectonics no longer has these in stock as
they are doing their builds with the factory 92.5/8mm crank now. I'd check
with Ron's, Eurospec, and other VW tuners. Perhaps there is a vendor on this
list that would care to enlighten us on this subject. Eurorace sells a
forged piston, don't know who makes it though. Seems to me there are enough
of those stroked VW's out there we could get some sense of quality.

>Bruno K. said that they don't last, although he didn't give any sources of
the pistons. I can have pistons made if I can't get confimation. Checked
with my local dealer, EV crank is approx. $900. but none are available in
US. However, I did locate 2 motors from salvage yards. Whatever I hear will
be checked fully by a top automotive engineer. Whatever he says is gospel.
