abf is the engine code for the tall block 2.0l 16v, 9a and 6a are the engine codes for the short block 2.0l 16v. you should be looking at up to 170bhp for a standard well set up conversion into a mk2
So are we talking, Cams, gas flowed head, 4'2'1 manifold + exhaust system to achieve 170bhp for the ABF engine???
