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
