Rob,
We need to see more pictures with the bodywork off, but I don't think it's a 'name brand'. It's obviously been doing AUTOCROSS in it's most recent life (C-Mod) and the tires/wheels/engine. The engine is a later model - probably a 1600 base with oversize jugs - the biggest I've seen is just under 2 liters - like 1950cc with dual weber carbs. It MIGHT have been based on a 'true vee' in the beginning, but I don't see anything but AX there now. The left side looks 'strange' to me - can't tell if the intake manifold is 'just laying there' or if it has been BROKEN OFF. The right side seems to have the direct intake with a carb on top, but only the manifold is on the left and it's not 'mounted'.
The rear suspension is definitely NOT 'original VW' - more like what I've seen on a few other 'real' vees.
Take the front cowl off and get a pic or 2 - someone might recognize something there... or you might find some info on a plate or tab there. Check the left side of the roll bar for a stamping .. something like .. 03-166 .. some 2 or 3 digits (probably vertically), a dash, then 2, 3 or 4 other digits. If there, those would have been stamped to mark the car when it received a log book for road racing and you might be able to dig up more info based on the numbers.
