My 205 4X4 Cosworth
Discussion
I think you are pretty close on the weigh, I will have it corner weighted soon but expect around 1100 wish when you take in to account the running gear, bodykit and cage plus the added turbo and intercooler etc...so it could be near 1200. I will work out the power to Weight once I have the dyno plots and the car back to weigh it.
There is a fair bit of trim stripped out plus the old rear beams are pretty heavy but then I have an extra diff to consider.
We already know what is needed for 520 BHP but I need the new gearbox in first to handle the power. My supra diff is all built up and running the MK conversion to fit the Cassie. I am going for an oppliger close ratio long box as they can handle 700 BHP and the ratios are much closer so the top end will drop to 150 mph at 7200 but the engine will be in the sweet spot more of the time so acceleration should be vivid.
A similar spec car was quicker than the owners V10 Limbo but he had a much more laggy turbo and about 30 BHP less.

The Volvo 480 had just a single engine, but it was in the back. God, that feels like a lifetime ago now..........
Ah, better memory than me, and it was indeed a lifetime ago...........well, more than half of mine anyway. I was in my early twenties, had hair, and rode bikes back then! 
Basic spec:
Quaife front diff 3.9 ratio, supra rear diff 3.9 with weir kit, bad dampers, Wrc bladed adjustable anti roll bars front and rear, Wrc front and rear cradle with Wrc hubs, Wrc spec cage, close ratio 4x4 box built for 700 bhp.
Doors and boot are carbon Kevlar, bonnet is full carbon fibre and the wings are fibre glass and Kevlar.
The cage, cradle, connecting suspension rods and front suspension cradle are all in super strong but super light t45 steel. Hubs are billet alloy so we have saved a load of weight off a normal 205, plus the interior is stripped with just light buckets. The doors alone were over 25 kilos lighter (for the pair), bonnet is around 8 lighter and boot is 12 kilos lighter. The majority of the bolts on the car are titanium (every external bolt on the engine is titanium).
The engine is chassis mounted as per a Wrc escort Cossie so the front suspension can drop out on 4 bolts plus the top mounts and leaving the engine in situ.
It has a huge spec r intercooler now as these have proven to be the best as used on Rod Tarrys 200+ mph Sierra (same mapper as me)
The close ratio box has uprated viscous coupling for better split on the centre diff.

It has these hubs front and rear with huge wheel bearings and big discs all round
Front adjustable Track control arms, it has WRC style Adjustable compression struts too
Here it has the previous BTCC style 6 degree beam, before I stripped it out for the new rebuild. It has spent more time on my ramps than off it, sadly.
