I agree with you about the price but be patient, the stuff does keep popping up on ebay, allow £100 for two sets and stick to that if you want twin injector TBs.

I decided on the Porsche barrels after seeing a posting some time ago by "Wally" on the Shoptalkforums, Type 4 section. He used the barrels and pistons and modified the piston crowns and rods in an otherwise mostly standard 914 engine to give about 155bhp on carburetors. I've checked the cylinders and they could accomodate a stroke of up to 98mm

I have access to a really good machine shop so spacers are not a problem though head studs may be.

The heads are from a german company near Cologne and are very pricey but allow very cheap Type 1 exhaust manifolds in large bore sizes. Twin plugging is an option so this is why I'm interested in the VEMS to use in 8 cylinder lost spark mode to drive the twin plugs/COPS
