I am (slowly as time tight) building Mk2 ABF with ported head, Eaton M62 (Merc kompressor, not smaller mini M45). This has also been ported and the roller vanes have been coated with a heat resistant finish.
This will be fast road 'every day use' car so wont be a tempramental dyno queen, but built to be solid, torquey and reliable.
Air con bracket will be adapted, ARP head studs and maybe rod bolts, then wit MS or similar.
There will be some fabricaion but that's half the fun I think. It' all going without toomuch of a hitch so far.
