I _think_ at least ONE mount will still need to be fabricated. The major
benefit is not the mounts but the throttle is cabled as opposed to the
'fly by wire' throttle in the current cars.

Maybe but I'd think an uprated model would be a good idea. Perhaps
grafting a pre pump onto the Mk1. Need flow rates demanded by boosted engine.

Adaptive fuel line section to tget it from current location to new
location, don't think rerunning the entire thing is ness.

I think you would want to use an A2 radiator- good cooling, doesn't need
16v upper hose ($$$), retains overflow jug.

Intercooler should not be _requiered_ if not tuned to high, but is recommended.
Oil cooler need not be custom, but is mandatory, would incorporate one
with thermostat.
