Cast twinscroll manifold???

[rr06rs]

does anyone know if one exists??? I could see a large market for these if someone came up with one that paired the cylinders correctly!

None currently for a DSM, HKS used to make one for a T4 flange and later OnGreen copied it. The only downside is the gate passages are joined to a common flange. Technically, an EVO 8/9 manifold is a bolt-on to a DSM head, if you wanted to get creative making an adapter to bolt a divided T3 or T4 turbo to it.

Hmmmm.....that IS an idea.... I wonder how much room you would have for fitment?

Get rid of your ac move the alternator to the back and dump powersteering it would work. On my first gen ive done all that so it theoretically would be very easy for me to toss on an evo manifold and pick up some of the fp evo style turbos.

I'm not looking to run any EVO turbos. I'm talking about t3 and t4 twinscroll.

I think the biggest issue you'd have would be that in order to incorporate wastegates, you'd have to put them on the adapter, which would lower the turbo down pretty far. I don't think it'd be a deal breaker, though. I've considered fabbing something like this myself if I ever went back to a T3/4 frame turbo again. ATP makes something for EVOs already, you could theoretically buy one and cut it up and re-clock the outlet:

It still wouldn't clear the balance shaft tunnel on the front of the block without a 1" spacer at the head.

THIS IS VERY INTERESTING!!! I would LOVE to see someone use one of these with a ported EVO manifold and a 12-16cm ts hx40 housing. You'd have even faster spool than a ts tube mani and the topend of the .70 t3 housing, if not MORE!

As far as a divided ts adaptor for evo mani, yes there is one. Personally ive used one but I know of one person who had decent luck with it.
