Question For The MK1 RS2000 Guru's !

With an RS2000 Mk1 with bubble arches : building a look alike
Is the wheel track permitted to be wider than a standard Mk1 with standard guards with standard wheel track ?????
Jim

Any widening  of wheel base measurements require engineer certificate, Jim. You may have to check on bubble arches as guard extensions that arent fitted from factory will require certificate. I know officiandos will say yes they were fitted from factory (albeit SVO not passenger vehicle) Replicas or Tribute vehicles as they are now called will attract scrutiny by officialdom.Just the fact of needing a certificate for a pinto conversion is a pain because they were never built in Australia with a pinto in them :(((

Depends on the use of the vehicle.
For road registered use this would default to the original build codes/build date/specification for that exact vehicle.
For rallys (not road registered) would default to the conditions/class of entry.
For Escorts generally any bubble arch is added simply to permit the 7" or 8" wide tyres and still maintain the tyres well within the confines of the body work. Without the guard extensions the tyres would foul the original panel work and protrude outside the body.
However I have seen race teams significantly increasing the track width by completely reengineering the width of the suspension to improve handling and to fill out the the guard extensions.
Might be nice for a race car, but will cause a trauma for a road registered vehicle, with little if any advantage, execpt for perceived appearance.
 

I thought you were ok to do a 2litre in a Mk1 as long as you had the Mk2 running gear like struts, brakes, sway bar etc. As everyone knows both cars share the same platform.

The largest engine which was available in a Mk1 in Australia was the Twincam so 1598cc or whatever they were. So the 2litre falls in the size limits easily. However the RTA states you should now still check with an engineer.
 
Theoretically if your Mk2 isn't a 2litre it should be the same, as long as you had the 2litre brakes, struts, sway bar etc it was fine. Just because you had a model come out witht hat engine doesn't mean the rest of the car is up to handling that engine with standard suspension, brakes etc?

My last Mk1 had a 2litre with twin sidedraughts and both were engineered. So maybe it now is required.
Either way it wouldn't be hard to have engineered if RTA was persistent you needed it done.

From memory they imported 25 so they could be run at Bathurst.
I did know of one that was a road car.
I think the same was done with mk2's as well.
