Is it available so I can get on with fabricating a turbo manifold. I'll be going 2.7 low comp with some nice pistons and probably running a Garrett T28 turbo for now. Only aiming for a reliable 300bhp and don't want too much lag.

If you could let me know where I can buy said flange I'll be a happy bunny. Thanks in advance

I guess they are probably not the cheapest, but I'm pretty sure Demon Tweeks can get manifold flanges cut if you supply them a gasket as a template.

I'm 99% sure it used to be in their Motorsport catalogue.

Cheers,

I had some made up a while ago.

Had them done in pairs for cyls 1-3 and 4-6.

Seem to recall they were about Ԛ£40 a pair or so, but I had three sets made which brought the cost down a bit.

Check that the gaskets are a decent match because they rarely seem to fit perfectly.

I wonder if it would be possible to put a gasket onto a scanner, scan it in and then export it somehow to a CNC mill? That would be rather cool if it works like that!
