Zetec Engine Mounts

I ordered my Tiger Cat kit with the 'Zetec option pack' and, amongst other things, this included engine mounts suitable for the Zetec. These were originally designed for the Super Six and when fitting the engine, it became apparent to me that these wouldn't really be suitable for the Cat. This wasn't entirely a surprise as nobody had built a Cat with a Zetec when I started building mine.

The first problem was that the nearside engine mounting plate was too far back for the mount. This brought two possible solutions, either extending the plate forwards or modifying the engine mounts. I chose to extend the plate forwards. This is no longer a problem as Tiger now supply the chassis with an extended nearside engine mounting plate suitable for the Zetec mounts.

The ideal solution would be to have replaced the original mounting plate with another one, welded in place with a supporting cross member underneath providing extra support. Without any welding equipment, my solution was to bolt a steel plate on top of the existing mounting plate that sat over the side chassis rail to provide the extra support.

The next problem came when I fit the engine and mounts into the car. With the Tiger supplied mounts, the clearance from the front of the sump to the floor was around 35mm. I wasn't particularly happy with this as it seemed far too low. The obvious solution was to make new engine mounts. I made these on the car, with the engine supported on blocks, then removed them, affixed them to jigs and took them to my Dads next door neighbour to be welded.

I made the mounts using 60mm outer diameter round tube with 3mm thick walls and 3mm thick steel plates. These gave me around 90mm of clearance between the sump and the floor which I was a lot happier with. Diagrams showing the dimensions of my mounts are below. The first two are scale drawings of the top mounting plates which bolt to the engine. The lower two are side profile diagrams showing how far horizontally and vertically the mounts extend.
