I have both a 1.8L 8V and a 1.8L 16V available in close proximty to me. which one do I want???? Whats the HP rating on the 8V? I imagine I could turbo it quite easily at a future date. Could i put a 20V head on it? also anyone know the engine size that came in a 1982 rabbit convertable? Gracias M Blain
