Re: Thinkin\' about a 1.3 DOHC swap
Okay, too much information! Could a custom two piece intake manifold be built? I could (in my dreams anyway) take the EFI intake off a GTI DOHC, run it thru a band saw to cut the short runners off. This would give me four short runners bolted to the DOHC head. Then have a machine shop mill the runner openings into a flat plane, and have a custom flat aluminum flange welded or brazed to the runners. Not expensive yet! Next I would take flat aluminum stock and make a plate to go between a stock 1.3 SOHC intake and the new flange on the DOHC runners. This plate would block the water outlets on the SOHC intake, and adapt the original Sammy bolt pattern to the custom flange. We're talking maybe $150.00, plus sacrificing a GTI intake manifold. The result, my stock intake or any modified Sammy intake would bolt to the GTI motor. My only questions are, would the bolts fit in the small space? Would the intake make the DOHC motor too wide for the engine compartment? I don't have the DOHC motors yet.
