The On3 Kit is actually quite popular here. I know of bunch of guys here run it. Great starter kit for the price.

I have the 78mm throttle body and quite like it. 78mm is overkill for a NA vehicle, as the air entering the intake manifold should optimize for both flow volume as well as velocity (larger flow cross-section means lower velocity with a constant flow volume). It does make your throttle more sensitive though, which is why I like it. I'm sure for a boosted car it'd be excellent.

I emailed BBK a while back asking them how their TB compared to Accufab, since they have the best flowing TB/plenum. BBK told me they didnt test the flow. In a product that is designed to flow air not testing CFM is either incompetence or stupidity. Either way it doesnt give me much faith in their product.

They are all better than stock. You will get 2-3 rwhp with a tb/plenum upgrade. The best is Accufab. It's the 3 rwhp. If I remember correctly, the BBK 75mm combo got 2 1/2 on a stock motor. The 78mm is a fairly new product.

78mm is not too big....but also not required on your application & mods. If you just get an aftermarket plenum (assuming you still have the factory piece) and use the factory TB you should be fine.

That said, the BBK 78mm is a nice set up, looks killer & is plenty to support future upgrades like F/I, cams, heads, etc. 263/294 is pretty impressive for your mods IMO!
