The advantage of building your own car is that you can have whatever spec you want. Im using a jag xj40 so if you want to use a 190e then why not?
I've made my engine bay longer and wide though so you may need some chassis mods aswell. 
How long can i resist the temptation to drop a V8 in?

The 190 parts are far too heavy for a seven.
You can better try mx5 parts or 200sx.

From what I recall, the 190E uses multi-link rear end, rather then double wishbones. The Mk3 Toyota Supra that I have used as a donor uses a similar
setup. The problem that I found is that the point at which the rear trailing arm mounts to the chassis is pretty much exactly the same place the
driver and passenger would sit. I have decided to convert the Supra rear end into a double wishbone arrangement to get around this problem, which I am
hoping will work. It does make me think that perhaps I should have just used a more suitable rear end to start off with.

I've been looking at the190 as a possible donor for the second edition of the book.
The problems with the rear are that the rear uprights are fixed to five seperate links none of which are in plane with either the axle centreline or
the wheel mounting face.
I think this can be overcome by the fabication of a new upright with a machined bearing carrier, This also applies to the Vauxhall
Omega/Carlton/Senator range
There might be a way to use the original upright by fabricating top and botom bridging pieces, but I'm not that far on as yet.
The front upright may be usable, it has a top and bottom ball joint, which maybe suitable for mounting to a double wishbone/coilspringdamper
set-up.
Again I haven't done the calculations yet but with a blank canvas for wishbone pivots etc, it should be possible to get a workable geometry for
the upright.
As standard the upright steers from the rear, which could be a problem regarding engine clearance, but the steering arm is a bolt on unit and it may
be possible to swap them side for side or fabricate new arms which front steer.
The four cylinder engines are tall, about the same as the pinto, I don't think this will be a problem in the Haynes Roadster, but could be in a
Locost chassis.
The six cylinder engines are the same height but 300mm longer and quite heavy.
Gearbox wise the tunnel will need widening, probably about the same as for the MT75 mods on my forum.
Nothing is impossible, but you do need access to the right suspension software to ensure that any changes work, don't got bolting stuff on and
crossing your fingers.
If I can work out how to take diagrams from PDF's i'll post some pictures of the bits.
Cheers
Chris
Note to all: I really don't know when to leave well alone. I tried to get clever with the mods, then when they gave me a lifeline to see the
error of my ways, I tried to incite more trouble via u2u. So now I'm banned, never to return again. They should have done it years ago!
