Tubro question re: JE Pistons

[dswalterwi at gmail.com (Don Walter)]

JE Pistons is owned by WiseCo.  WiseCo is their premium pistons and are
better design.  They have many features that the JE's do not.  The best one
is that they use an offset wrist pin design to eliminate the piston slap and
the oil scraper ring is 3mm unlike the 1mm on the stock 2.0L engine.  You
will not have good luck trying to go through their distributors as they will
make you buy 8 pstons.  I called the company direct and they were happy to
take my order direct.  In fact they did not have an off the shelf 16V design
so they designed one on Solidworks for me. They added the domed area for the
squish area, although you would want a dish for lower compression.  Mine was
10.5:1  I sent them one of my pistons for verification.  I had them give me
an extra 0.050 cleareance for the valves. The best part is that they were
cheaper than their JE counterpart and they were custom made.  I paid $500 if
I recall.  Let me know if you want any other information.

Here is a link to my custom made pistons:
