So im very interested in doing this swap. I have a msd dis 2 ignition box and i am wondering if that is going to change anything. The is capable of a main rpm limiter, a 2 step limiter and a timing retard. I intended to use it with no2 but never got around to it yet.

I bought a svt intake manifold with the injectors, tbody and wiring harness allready on it. I understand that i need the msd switch and some hoses, but what about the alt bracket. there was never final word if the stocker could be rigged. Also i was thinking about taking the ac off my car. would that effect any of the hoses i need and would it mess up the routing of my s-belt? I also have an svt block and head laying around. You said tom has the vct delete kit. And i could just toss that onto my car and have a very nice day?

First off I'm new to this site and I'm sorry for resurecting a thread that hasn't had a new post in over a month.

Now to topic, I have everything needed to install this manifold on my ZX2 except the pigtail harness for the IMRC. I bought a SVT fuel rail harness thinking the IMRC would be on there, well it wasn't. So I'm having a hard time finding this pigtail. Could anyone either direct me to a place to get one and/or tell me what prongs on the IMRC are needed for which wires?

A question about the MSD window switch and the IMRC-is it pulsed or constant feed power to the control box?
And has any thought been given to using a shift light (either a stand-alone unit or one in an aftermarket tach) to adjust the crossover point? Or to relace the MSD window switch completely?

Well lets bring this post back to life. Just finished the SVT intake swap this weekend. Only thing left is to work out the high idle/hanging revs.
Pics...





Instead of the MSD 8969 I used an 8950 rpm switch to control the IMRC. And I wired in a potentionometer to replace the rpm "pills" MSD sells. This way I can control the rpm switchover point.

To fix the hanging revs, I modded my IAC port, what I did was scuffed it with 80 grit sand paper, cleaned the port out with carb cleaner, allowed it to try, then filled it with 2 part epoxy.

Then, I drilled a 5/32" hole in it, and tapered the opening with the drill bit.

The revs and idle was a lot lower.

Another thing to check is make sure the manifold is mating against the intake ports on the head properly.
