I will be and Currently AM doing the 420a to 4g63t 6bolt swap in my 95 2gnt talon. I picked up a fwd 5spd turbo 91 eclipse for $250. Needs rebuilt but have tons of parts and resources. It had a snapped balance shaft belt and it made the timing belt skip a tooth. But tore it down and all looked well. Havent got around to checking the head yet. I will be documenting my progress since noone seems to have done it yet. Please dont hate 2gnt owners. lol
Oh and i have TONS of 420a parts for sale...if interested just contact me. i may ship items. but prefer pickup
