Al,

How is your set up different than the one Ed A. had that didn't work t= oo well? It was also

one throttle split into two runners.

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 th= e group.

The inlets are 42mm (appx 1.65 in.). Is this t= oo big to the point that they would be incompatible with the injectors?&nbs= p; 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 R= enesis injectors?

This setup also would allow the use of a lightweight airb= ox thus simplifying the intake system from a manufacturing stand= point.

Thanks in advance,

Bryan
