The EBay HEI Distributor arrived today and looks good. I didn't get a chance to hook it up today but I can only hope it works as good as it looks. I won't carry on about it as I know it's not really a turbo specific upgrade.
A few pics for those interested:
Found a SPA Turbo Wastegate, Fuel Regulator and Blow Off Valve that I like, but having trouble locating a suitable electric fuel pump (at a similarly suitable price of course). Next purchase will probably be the Offy Intake.
