Hey has anyone heard of a ITB turbo application?
I was thinking about building a manifold using ITB's instead of running a single throttle body. Any info on why is will or will not work would be helpful.

Speak to Tony the Tiger and search for threads by him. He has had an ITB boosted teg for years.

R32-R34 Skyline GTR is ITB'd and turbo from the factory. So are pulsar GTiR's with the Sr20VET.

Plenty of people have itbs on turbo setups. The issue is making an intake plenum for them. There aren't any generic ones each is tailored to the application

I'm currently doing a 46mm itb setup on my motor

But where are you getting your itbs from? If its from a bike you need at least 1000cc and larger bikes. Mine came off a bmw k series bike

I have not put much thought into where I was going to source the ITBs from but, I saw they were available online. My thought was to machine a box on the intake end of the ITBs would fit in... It would almost look like a golden eagle manifold. My only question is, is it worth changing my current performer X setup?

that depends on so many things. TB size, plenum volume, etc.

Yea there's a lot that goes into plenum design

You need velocity stacks for each runner and runner length will have to be short to use a plenum due to clearance issues with the firewall. Now if you have a shaved/tucked bay and you've removed all of the mounting stud bs and such that goes with it you'll free up a few inches

Funny you say that, after my last post I was browsing though pics of ITB's and noticed there was not much room between the firewall and intakes. So I decided my current setup works well enough that it is not worth the hassle for my Daily D, at lease not yet.
