My quest to design and build a mid-engined sports racer from scratch. It will comprise of many newly fabricated components along with repurposed parts from other vehicles such as the 2.5 Turbo engine from a Volvo 850 the running gear from Mazda Mx5 and the driveshafts from a sierra xr4x4. The body work is the only thing I have purchased and even that will be extensively modified and a complete front section made from a mould. Wish me luck.

Tonight I took some measurements and cut the drive shafts to length which allowed me to arrive at a final overall rear wheel width of 1818mm.  I'll get the shafts welded up tomorrow.


I also started making some engine mounts, the plasma cutter doesn't like 5mm plate much.  I got one engine mount plate done though.  To save time though I think I'm going to try and get hold of the OEM mounts.

Starting the chassis is drawing ever closer.

Land rover engine mount, I have been practicing with the plasma cutter doing round base circles for the eventual engine mounts.
Using Sierra outer stub axles and Volvo 850 inner shafts and CV meant that I would have to make or have made hybrid driveshafts.  For the purposes of setup I decided to cut, sleeve and weld the shafts that I had.  When I have decided on a final track width I can use the cut and shut shafts as an exact pattern for a driveshaft shop to produce.
Been working on the rear drive train.  Will be using a pair of Mx5 rear uprights but with modified Ford Sierra xr4x4 stub axles and uprights.  Had to machine a tiny bit off the Sierra hub but nothing major and was remarkably close to the Mx5 dimensions anyway.

The reason for wanting to use the Sierra stub axle was to be axle to have a replaceable CV joint plus removing the shaft without damaging the CV joint on an Mx5 stub axle is a PITA.  Also there are uprated parts available or the Sierra CV's and I am planing on throwing well over 300 HP at it.

The Start-This is the third scratch built car I have started, I am determined to see this through.

My Dad and I constructed a 12'x1700mm build table, you can see the donor Volvo engine sitting on the top.  The table still needs bracing to sure it up but is pretty sturdy.
