Hello all,

I have a chance to purchase a TWM = throttle=20 body(see attch pic) at a very low price.  I have = a couple=20 questions for the group.

 

The inlets are 42mm (appx 1.65 = in.). =20 Is this too big to the point that they would be = incompatible with=20 the injectors?  I plan on using 1-1/8 and1-1/4 in=20 runners.

 

Also, the bosses are sized for = Bosch,=20 Rochestor, or Lucas injectors.  Does this necessarily = eliminate my=20 using the stock Renesis injectors?

 

This setup also would allow the use of = a=20 lightweight airbox  thus simplifying the intake system = from a=20 manufacturing standpoint.

 

Thanks in = advance,

Bryan
