MK3 2E code is direct fit, MK3 AGG and ADY are too but you need to change the dizzy for a 2E one. if you keep the std exhaust manifold and downpipe it all bolts together perfect without any modifications. some 4 branches will hit the tunnel due to the 2e being a taller block. several audi lumps as well as the 2 above will also fit, ABK being one I know of its the audi equivalent of the MK3 2.0 8v lump
