Is it that there r 2 places on the zorst manifold for them to bolt on or r there 2 exhaust manifolds??

Twin turbos can be either connected by two seperate exhaust manifolds (using a balancer pipe in some cases) or a one-piece manifold with twin outlets built onto it. The former is far more popular than the latter and is representative of how the RB26DETTs come from the factory.

Don't know about the 34 Gio, but on the 33 there's 2, one for each....

Peter,

I think you got the last line out of context

Sorry for the confusion, Peter. Maybe my writing is not real clear but I meant what Bean said.

Quick question.....do they both come on at the same time or does 1 spool up before the other?

Do some twin turbo motors have a big & a small turbo that run secquentialy to overcome lag? Or would this just cause loads of probs?

RX7s, Legacy B4s and Supras.

Very complicated piping and tubing....and most people ditch them for a single

I agree to that,, MOST Supra owners who do turbo upgrades either go for normal twin, or a big singel.. they ditch the idea of sequential.. to my understanding its not vey effeciante when trying to make good HP numbers.

But the idea of the sequantial is still very nice am glade people have tried it and manufacturers are willing to take risks in making winkel engines and sequentials ,,
