That was painful to read. Look man, its a turbocharged car, your throttle response is going to suck anyway unless you are already in the powerband. Just get you a big single throttle body and enjoy.

I'm not saying you shouldn't do this, as it would be sweet as f***, but it is a hell of a lot of work, and you have to be good at fabricating.

Wow. If the OP doesn't start making his post's easier to read and more coherent, I'm locking this, and anything else he/she does until then.

But we have to read what you post in order to help you. And there are some of us (ahem..me) that have english degrees that have to muscle through your posts and facepalm all the way.

An ITB setup is wonderful for response and midrange torque, but the necessary fabrication is not worth it. There was a poster on here at one point that made his own barrel ITB setup (he was German IIRC) and while wonderful engineering excercise, not at all worth the meager benefits over a properly tuned surge tank style manifold and runners. Lots of high HP RB26s have converted to a single TB. This a wonderful idea, and if you have the time, capacity and funds...go for it! But I suspect you are just bored and looking for something to chat about.

Oh, sorry then, I had assumed it was the "other" half of the plenum you recently won.

My first query for a pic way above was to see the actual setup of linkages and throttle for the itbs...

looks like its going to be a hot auction as its already quite high with a few days to go, along with a few fimilar bidders. Ive only ever seen one other nismo adaptor before.. it was far from cheap too.

I produced an adaptor similar in design for my throttles, it was a major headache so it may definately be worth the money it goes for.
