George,
I am only contemplating at this point. I have a chance to purchase this throttle body for a great price. So, I don't have a choice on the size. FWIW, the smallest they offer is 40mm anyway. I am just trying to get an idea if this a good option. I have heard that even though the engine is a 1.3L equivalent, it digests air more like a 2.3-2.5.
Again, the runners will taper right after the TB's to 1-1/4. I am thinking that this will help the velocity.

Bryan,
Why are you running 42mm, is there a narrowing of the throat that is say 38 or 40 mm?

Hello all,
I have a chance to purchase a TWM throttle body(see attch pic) at a very low price. I have a couple questions for the group.
The inlets are 42mm (appx 1.65 in.). Is this too big to the point that they would be incompatible with the injectors? I plan on using 1-1/8 and1-1/4 in runners.
Also, the bosses are sized for Bosch, Rochestor, or Lucas injectors. Does this necessarily eliminate my using the stock Renesis injectors?
This setup also would allow the use of a lightweight airbox thus simplifying the intake system from a manufacturing standpoint.
Thanks in advance,
Bryan
