The displacement and compression boost add power at all RPM. By default you get 1004cc at 12.5:1. However, you can specify any bore; any compression ratio; you may have to wait a month. The kit comes with two pisons, rings for all, two pins, four clips, and a pair of pure copper head gaskets for 675USD. 825USD for ceramic crowns and treated skirts. Plus between 80USD and 100USD Priority International Shipping.
First, some proof that we have some knowledge of - and support for - the TR1. Click on any picture for a larger image. My sources inform me that the quality of fuel is better in Europe and the enthusiasts like to tinker. So it is with confidence that we sell these detonation-proof 12.5:1 pistons to our friends in the Old World.
NOTE: I need measuremnts for the depression around the bore. I plan on mfg a copper gasket that will squeeze into place. If your motor is apart, please send me these measurements; especially height. It will be slightly larger then a stock head gasket. Both the ID and OD should need a bit of persuasion with a plastic or rubber mallet to drop into place; the gasket should then stand a little proud of the bore ring. Tightening down the head will form it into its final shape. The TR1 was not sold stateside, so I need this so you'll get as good a seal as we do here. Whoever contacts me with this info first will get a free pair with any purchase.
