Porsche 944, 951, 968 L4: 2.5L 2479cc and 2.7L 2681cc (both 78.9mm stroke as used in 944 variants); 3.0L 2990cc (88mm stroke -- as used in 968, stroked version of scraper)   $79.95

Teflon® stock and knife-edged versions $199.95; the Teflon® version includes the rear screening found on the windage tray setup.

   Knife-edge:

Windage tray setups:  The windage trays have either the steel or Teflon bladed upstroke scraper removably built into the framework -- this is so the scraper can be adjusted without the screen in the way.  In addition, the windage tray setups have a downstroke scraper that bolts onto the frame.  The downstroke scraper was originally used in the 928 windage tray setup and has been adapted over.  The 944/968 engine is derived from the 928 V8.

These pictures show the assembly nested in a 951 pan with no modifications needed to the pan or baffle; the jig holds the bedplate the correct distance away from the pan (accounting for the 8mm thickness of the pan gasket):

You must first determine whether you have what we term an "early" or "late" style pan (968 and some earlier engines).  There are a number of different pan variations but for the windage tray it is the style of the internal ribs that is important.  The style of the internal ribs determines the screening pattern used.

This is the "early" style: 

This is the "late" style: 

$509.95 for the steel version; $609.95 for the Teflon bladed version.

We also make an oil pickup support bracket for the 944/951/968 engines that can be used with our products or by itself.  The customer uses the engine as a jig and the bracket can be brazed or welded into place: 

$49.95
