GS, try calling Anson at Filcarrozeria. He can advise you & hook you up with speed demons. Tell him Doc Rick referred you. New webers are kinda expensive & since you are in an experimental stage, baka mapamahal. Most of the guys i know are offroaders so I'm not sure if they can help. Sammy engines come in 660cc also & may fit. The multicab engine may work, it is modified like a bike also. If things dont work out, get a 96 sentra & stick in a 2.0 engine. Good luck & pls give an update, intriga ako sa project mo!l
