AVAILABLE SPECIAL ORDER ONLY.
We have been working with the people
at JE on our pistons since 1978. Through our racing engine research and on
track experience we have continuously modified our designs for better
performance. We won four SCCA National Championships using the same piston
design you can now buy off our shelf. Professional engine builders all over
the world use our pistons.
- Compression of 12.5:1 is measured with standard cylinder head
height of 112mm and 114mm Reinze gasket
- With lightweight JE pins our piston/pin total weight is 15%
lighter than Borgo 10.4:1 and 10% lighter than
Our JE 2000 big valve race piston was developed to be as good as the
Cosworth pistons costing nearly double the price. Our pistons will bolt in
all but the most severely milled heads. The Cosworth can have interference
issues above .020 milling. A set of our pistons is still a bargain and make the
same power. This 84mm piston keeps the displacement under the FIA 2000cc limit
and fits the standard bores.
It is both convenient and cheap to be able to use the standard size
- Compression of 12.5:1 is measured with standard 112mm head &
1.4mm Reinz gasket
- Deeper valve reliefs accommodate most performance cams
- Larger valve reliefs will accommodate oversize 46mm intake and
41mm exhaust valves
