Whoa, nice find dude! I didn't know a chassis could be picked up for that sort of price. Given all the bespoke components made of exotic materials, I can't help but think you got quite a bargain.
Considering this forum's interests, you should disassemble it, measure, photograph and make drawings for all the parts, then post them here!
What are you planning to do for:
I imagine motorcycle dampers will get you into the size range you need, while being relatively inexpensive. Torsion springs I'm sure will be a challenge, if their not on the car already. Hopefully you can fit larger diameter wheels and run non-F1 tires.
I don't know of any way you could race this, but money no object you could restore it and make some appearances in classics events. I'd say aim to make it road legal.
The H1V8 is nice and compact, as you say (and is already dry sumped), but are you sure you don't want to get up into the 700-800hp range this chassis was designed for?
75° odd fire V8 2.8 LITER, 170 cu. in. displacement (3.0 liter optional)
84mm Bore X 63mm Stroke (67 stroke optional)
4 cams, 32 valves via internal silent chain
530mm wide x 485mm long x 530mm high
400HP @ 10,000 rpm with stock street cams (higher spec. is available)
245 ft-lbs torque @ 7500 rpm
200 lbs engine weight
Billet nitrided steel 180° crank
4340 H-beam con-rods with ARP bolts
Billet 6061-T6 aluminum crankcase
Dry sump 0il system with 4 stage pump
7.25" or 5.5" Twin disc clutch
DTA S80 full sequential ECU
How much room do you have between the monocoque and the front face of the gearbox? If I understand correctly, the length of the engine (and whatever subframe you create) will only affect the fit of your bodywork. Everything else is flexible, being attached ahead of, or behind, the engine.
A turbo Mazda rotary could be another option (compact, high output):
Length 675mm x Width 549mm x Height 520mm
An LS-series V8 would be the most compact big
engine you could fit (like what run in LMPC). How amazing and unexpected would it be to have that sound coming out of the Earth Dreams
LS6 road engine dimensions:
730mm length x 627mm width x 717mm height
may be another way to complete your project. You could turn up at races and car shows with a new sponsor livery. Say, find a biodiesel supplier and drop in a turbodiesel. (again, how cool would that sound?) Find a battery or electric motor supplier, convert it to all electric.
Nice pics by the way, its always difficult to find high res imagery of modern F1 components:
