So after a year of talking about it, we finally got our act together and bought an Exocet shell.
The donor car is our track car (which incidentally never saw much track action due to always being a "project"), which was a 1990 MX5 but with the following gear:
- 1.8 SVT engine from Mk2.5
- Megasquirt 3 DIY Ecu with sequential spark (COPS) and injection + MS3 controlled VVT & EBC
- 6 speed gearbox from MK2.5
- LSD Fuji Diff from MK2.5
- Mesiter R coilovers
- de-powered steering rack (shorter ratio than manual rack)
- GT2871R Turbo with tubular manifold, divorced wastegate & 3" exhaust
- fibreglass bucket seats
We picked up the purple/orange shell on Thursday, that I think Stuart used as the promotional Exocet a few years ago; we loved the colours and this one was unique in its' own way with the rear wing and the stripe through the middle
I'm sure there will be fitment issues for the engine/turbo but I have some welding experience with stainless and aluminium and we are very lucky that we have a well fitted workshop at our disposal.
Our plan is to use a tubular lightweight subframe from Crap Engineering, sand/soda blast & paint all wishbones/rear subframe etc, replace all bushes with polybushes, replace all bearings, boots and basically inspect and replace all other components as required. We will also try to minimise weight were possible by using aluminium pulleys, and possibly a hybridstainless/aluminium home made exhaust. We will not be using the original harness and we will re-wire everything from scratch; we are electronic engineers by trade so wiring does not scare us. We may also look into using our own instrument cluster (we already manufacture a small LCD display with dual channel frequency inputs and various analogue options) but this decision will be made much further down the line.
We will also be fitting a custom direct port water injection system (mostly Aquamist parts) as I have some successful experience from fitting a direct port WI system to my 1.8T Audi TT (running large GTX30 turbo); much better ignition timing under boost, cleaner and cooler engine and more environmentally friendly emissions with no real drawbacks (as long as reliable failsafes are implemented). Since the Exocet will not be used in cold weather, no need to add methanol and we will use a simple domestic water distiller, reducing WI running costs to a minimum.
Further down the line, we will look into getting a forged engine built to get the most out of the turbo but this will be after it is up and running.
We are very excited and we will update this thread periodically with the progress; however we are not in a rush so the progress is likely to be slow and steady.

the manifold pushes the turbo out too far.
