Hello Paul,
I have been looking at getting my engine mount at or in front of the
CG.
I have attached a Auto-cad 12 DXF file for you to look at.
This new arrangement lets me use the standard exhaust manifold and
turbo.
It also makes the 20mm pipes wider apart to house a wider radiator.
All the material I have in stock of offsets.

AN> Looks good with a few minor mods as shown.

AN> Keep the bottom of the oil pan as small as possible to minimize

AN> Mock it up and make sure the stock turbo fits. In my case the the rubber
AN> bushing holders had to be 29 inches apart. Your firewall
AN> mounting points may be further apart than mine giving you more
AN> room for the motor mount tubes.

Thank you for the quick response to my mount design.
At the moment I am 25 mm in front of the CG of the engine and PRSU, if
I go any further forward the standard boost regulator will hit the
20mm tube mount.
I would like achieve more bolts through the T bar flange as your
drawing and will have a look at this and see how wide I will need to
make the rubber mounts. The extra bolts is not that important as I
will weld the flange of the T bar transverse only to the sump 4 mm
plate.
I have some 40x40x3 Box section that would do the job but I than can't
get the bolts into the sump plate with this.

Don, I don't think this is a good place for the rad.
The Mustang II cowl is not deep enough to get enough ram air to it.
Also it is subject to heat radiation from the turbo.
I would put it vertically on the cool side (spark plug side)
of the engine.

Ops. I forgot the rendering. Here it is.
