st205 side feed intake manifold, what gen 3sge can i take a manifold from Options

[afroman]

I searched and couldn't find what i was looking for. I also searched mr20c.com but most topics were about the 2nd gen 3s. i would like to go to a side feed intake manifold when i start to do my swap. I plan on going front mount and would like to simplify the intercooler piping and not having to run it close to the exhaust mani. so my question is what year 3sge. can i take a manifold from. also i if can some how find a beams mani would it be worth the money. if you think this is a stupid idea let me know im just trying to get my research done.

So then if I cut the ACIS wire that goes to my ECU, the ACIS should still work

Yes, the ACIS will still work, as long as its getting a vacuum signlal. From what I've read on the system, it looks like the ECU also forces the butterflies closed at a certain throttle position, which will be lost by disconnecting the VSV.

With the last 3SGE's I received, the canister on the back of the intake manifold was connected to the fuel pressure regulator, not the ACIS system - which doesn't match the diagrams I've seen. Is this the same with your motor?


BTW - nice description of the ACIS on the 7M:

I gotta do some research on this. I remember there was a diagram showing how the ACIS system works on the 3S-GE's but I lost it.
