They designed their own manifolds and had them cast up I believe. The ones they probably have for sale now must be old stock......they were all the go back when the 637's were current. I would be certain that you could just buy a new manifold from one of those guys if you wanted to do most of the work. Surely they would be happy to get rid of the manifolds.

637 with a towoomba turbo kit would do 140klms/hr!!!
I used to be indecisive, but now I'm not so sure.
i don't know the answer, but if the manifolds are the same for 4d33 & 4d34, then this might be the go?

I believe that this, or a similar eBay link, has been suggested in another thread.
I think it was Alan that noted that this manifold design does not have a wastegate port.
My attempt to build something to go somewhere else...

140km/hr they are hair raising enough at 100 on our roads
Would be great to find who still has these manifolds

I believe the pictures I saw of the Superior Turbo setup had the airlines running around the back of the engine. A kit for $2,600, how much for a 3 inch exhaust, any warranty. I'm more than capable of fitting a kit myself but I would hate to have problems with it. DanOriginally Posted by Tonkatuff

You can modify the standard exhaust manifold to take a turbo on the 4.2.

That was what i was wondering alan the exhaust is a flat mount to the manifold socan you just machine an adapter plate. Still have oil lines etc.
Dan i don't know all the details, the mob is in sydney and have a lot of info on the net, they were very helpful.

Mine has an adaptor plate welded to the manifold with the old outlet welded up, I will take a pic and post it, i also seem to remember seeing a name somewhere of who installed it.
