After the successful introduction of our Austin DS5 cylinder heads we have recently added new products to our DS5 inventory. These new parts are the perfect complement to the cylinder heads and provide a perfect opportunity to upgrade your engine if you're undertaking a rebuild. These parts are all exclusive to us and are not available anywhere else.

The Austin DS5 6 cylinder 4.0 Ltr engine, is very similar in design, to the 2.66 Ltr 4 cylinder Austin engine used in the Healey 100 and A90 Atlantic. The DS5 was used in the Jensen 541, 541R and 541S as well as in the early Jensen Interceptor.

Austin DS5 - Jensen - Dished Top Pistons 6cc

     Our Die Cast Pistons are made specially for us by Omega, one of Britain's leading competition piston manufacturers. They have the original dish of  6CC ideal for Fast Road Cars wanting a compression ratio higher than a 100M, providing the cylinder head and         block have not been skimmed.

    Being lighter and having a better design than the original they are not only stronger for performance use but are also quieter for road use. We have used metric sizes in order to take advantage of the latest ring technology and reduce crank case pressure.

    The sizes stated are the actual bore sizes, all clearances have been allowed for on the piston.

Please note that these are supplied as a set of 4 with gudgeon pins to suit standard clamp conrods. You will need 1 1/2 sets for your Jensen. 
Please contact us after purchasing online so that we can amend your order.

Austin DS5 - Jensen -NEW CAMSHAFTS

There are considerable differences between new and reground cams so the decision should be taken carefully. Manufactured to the original specifications with original lobe position. The oil feed to the centre journal is as standard and the lobes are made as large as possible to reduce wear. Using the best material available for long life and fully heat treated. Now also available as a Billet Blank for final profiling and heat treatment to your specification, by ourselves or your cam grinder.

Cam followers and lube sold separately.

PROFILES

  • DWR 1 Profile is the only camshaft which will fit without any valve pocket reliefs. This profile is similar to the original cam and so works well in any standard or mildly tuned car.
  • DWR 2 Profile is high lift with 300 degrees duration (may require valve pockets). This profile is very similar to the original ‘Works' profile and ideal for race and rally cars.
  • NOW AVAILABLE DWR 4 Profile is our Austin Healey 100/S interpretation with 278 degrees duration, this puts it midway between our DWR 1 and DWR 2 Profiles in performance terms, providing good power with very smooth delivery. This 100S profile is equally well suited to the Jensen Engine - ideal for a Mille Miglia type rally car.
