I'm really happy at how well our new intake for the manifold for the Porsche 928 has turned out! Is is called the "Hi-Rise 654" manifold, and is designed to perform best on our 6.54 liter 928 engines. It will be going to the engine dyno very soon for testing and measurement.

We have now been supplying our re-manufactured intermediate plates for a little over a year and have had no trouble with them in the field.

This is not merely an intermediate plate with a machined center; we manufacture a new center section and replace it completely, making sure that your clutch stack height is right and your clamping force is what it should be.

At $720 with core exchange, they are less expensive than a new one, and certainly less of a "chance" than a used one (if you can find one).

We have models for all pinned twin-disc clutches from 1980-86.
We do not make one for the 78-79 concentric clutches.


I have had a number of requests over the years from our International customers wondering if they could buy our cylinder liners, pistons, rods, and stroker crank so they could build there own 6.5L locally and save the expense of shipping an engine around the planet.

Here you go!

All the same high-quality parts we use ourselves and have been proven to provide great reliability in your 928.

Compression ratios are available from 8.5:1 to 12:1, and we can set you up for anything from high boost to naturally-aspirated.

Call or write with any questions. I have one crank in stock right now (and others on order), so current lead-time would be about 8 weeks to have the pistons made up to what you need.
