Re: Kiwi scratchbuilt

The starter/ flywheel with these Porsche trannies is somewhat of a mission but I have trodden a slightly different path on this one.

Primary concern was that I wanted a light and compact flywheel which really dictated a forward ring gear. I spent a lot of time looking at how to extend the starter nose forward to suit using the standard Porsche mounts. In the end there were too many problems to surmount and space was tight too.

So I decided a forward starter mounted off the adaptor plate was the best way to go. This made my new Hi Torque starter redundant because the direction of rotation is wrong when it is turned around. So I ordered a new 928 unit from 928 Motorsports.

Anyone in NZ want a brand new, unused, Hi Torque 930 starter at a good price? Fits G50 as well I believe.

I initially wanted to fit it to the LHS because of the dry sump lines on the RHS but after already doing a chop on a couple of chassis tubes it became obvious that configured that way there just wasn't room as my motor sits really low in the chassis. So had a really close look at the RHS and found I could just fit it in and the drysump lines too.

In the end it was quite simple to do and you can see how compact the flywheel is.
