As far as using stock things, can it use stock injectors, throttlebody and vacume lines/hoses as well as the iacv valve?

Just looked at a couple of pages, its advertised as a plenum in some, and as a intake manifold in others.... so is it a full manifold or just the plenum?

Yes it's a full manifold and uses all the stock parts. pretty much comes with everything you need

EDIT: forgot, you need an adapter to use the stock TB. It's designed for the Q45 TB

As far as the Q45 TB, do you need anything to make that work? Do you use the Q45 TPS and it just works as far as voltage and everything, or do you have to get something to compensate like a z32 maf. Or, do you simply just use the tps from the Rb25 in the q45 tb?

IF you have a SI Rb25 you can just plug in the Q45 TPS, if you have a SII you have to splice the wires.

No, the q45 TB is to big for stock rb25 intake manifold! I believe 80 or 90 mm

Does the Q45 throttle body vary with years? I know that the q45 uses 2 different ignitor chips for their different years, so Im wondering if the throttle body is any different?

I have a series 1 rb25.

That one, that's a good price BTW. I paid $100 without a TPS and had to spend $60 buying one.
