In the near future I will be swapping an lt1 into a 944 and was wondering what the possibilities of ITB where.I come from a vw background so ive seen plenty of itb's on 4 cylinders and was wondering if it is at all possible to run them on the lt1. I'm not trying to build a monster engine by any means I just want the wow factor of the itb's.

 

With enough fab'ing anything is possible.

Does that mean that it would be worth it to invest the time and money when the aftermarket t/b's are plenty good enough.

Things to consider are going to be managing two IAC (idle air controlers) and two TPS (throttle position sensors), not to mention two throttle cables. I highly doubt you'll ever get cruise control and TCS to work either.

So, my opinion is that there are other places to modify to get the "wow" factor.

 

I assume you're talking about 1 TB per cylinder?

In which case I would say PITA, the LT1 does not use an electronic throttle. That would be quite a bit of money. You'd have to fab a manifold, TBs, and a monster linkage. You might have an easier time converting the LT1 to dohc... Then you could put the water pump on one side, and the opti on the other

I know Maserati makes V8s w/ ITB, but that's pretty high end.

 

If anyone could help you, it would be Kinsler. They already make a manifold for the LS1/C5-R with 8 individual butterflies. Could probably work up something using their Gen 1 SBC parts.
