few questions here,

1. was wondering if I could use the TB and MAF from a VG33E on my VG30I and what i would need to do it

2. if I could also use VG30E intake manifold

3. any good TB spacers and intakes out there?

4. is this true-->(throttle body and MasAirFlow sensor (Best bet is to just swap a VG33 plenum, TB, and intake plumbing, it's all 60mm. In fact, the MAF upgrade alone removes a HUGE bottleneck.)i beleave i herd it on this forum

1. I have no idea
2. yes, but you'll have some wiring to do. The TPS, MAF, etc wiring will have to be lengthened. Stuff will have to be moved around. Might be some work.
3. somebody makes stuff for the VG33, K&N has intakes, just make your own
4. I read that too, and I'm looking for those parts to try it out.

Welcome to N4W

so in theory that makes my vg30i into a vg30e?

Well, I guess I didn't go into enough detail. If you get rid of the stock TBI unit(and lower intake) for the VG30E of VG33E intake manifold, you'll be switching to a MPFI system with one injector per cylinder. Right now you have 2 injectors that are basically inside the throttle body. The computer you have now won't work with 6 injectors. You could buy the correct computer, or build one.

And wiring this all up might be a nightmare. The computer connection will probably be completely different.

I guess it might be cheaper to swap the whole engine out for a VG33E with a few miles on it. Then buy a new computer and harness, then lengthen it as necessary.

There's a thread about VG33 swaps that will have some more info.

Did that help at all? I wish I had some photos.

That's a VG30E from a 300ZX or something, but the important part is the lower intake plenum. You can see the small holes in each runner for the injectors.
