Well I am getting ready to do this later in the summer, DOCE style intake with Fuel Injection. But I was wondering if it would be better to use all the TB injector locatioins or if I would put the secondaries on the TB rail and still keep in the primary injectors in the intermediate housing?

If I think I understand what you're trying to say, you're going to lose the secondaries cause the throttle body injection manifold should replace both the upper and lower intake manifolds.&nbsp Keep in mind that the secondaries are placed in the lower intake manifold.

It really doesn't matter which holes you use, as the difference in placement is only going to be a matter of inches.

We had an interesting discussion about fuel injection phase angles on the Haltech Support list, and the Hitman mentioned that differing phase angles doesn't change the performance on a 13B that much.&nbsp This implies fuel injectors placement isn't that big of an issue...

Well Ted I was going to use the upper Racing beat manifold with the stock lower so that I could keep the 6PI, figuring that this TB set-up would take away from the bottom end power.
So I guess that I will just put them all on the TB so it will be a easier install.
