I've read through 9 pages of threads, after searching for "ACV" and what not, including reviewing RX7Carl and Pratches tutorial (very nice work BTW)... Most threads relate to soley removing the exhaust and the rat's nest - so now I have some specific questions for an "in between" job.

I have an un-molested '83 GSL that I'm about to install a complete RB exhaust system on. I am not removing the rat's nest, don't see any need to with potential cruise, A/C, etc vacuum problems - and frankly, the color is still good on those little adhesive dots that go on my solenoids - so I'm leaving them.

All I want to do is remove the stock exhaust, air pump and ACV.

1) According to the tutorial - there are electrical connections to the ACV. Is this for all years? If so, what should I do with them?

2) There seems to be potentially two block off plates often mentioned. I have an ACV plate only - what's the second plate for?

3) There's mention of a cat to carb intake hose. Is this for all years? If there one, and do I just plug it at the carb intake?

4) EXACLTY how many hoses lead to the ACV? Do you end up capping them all at their point of origin?

5) Are there holes that need to be plugged around the exhaust port, beyond what the flange/gasket will cover?

6) The metal/wire duct that runs from the heat exchanger to the air cleaner - cap the cleaner inlet?

Thanks for any help anyone can provide before I rip my daily driver apart!

If I'm not mistaken (I've done the rats nest removal on a number of 7s) you have to pull out the rats nest if you remove the ACV. The rats nest stuff gets signals from that and other wierd stuff on there.

If you don't have to worry about emissions, remove all of it!! You will take a look at your engine and say "damn, that looks better."

You will also be better off having brand new lines so that you know you're good to go for a while. There's fewer stuff to worry about that way.

Do like my Dad always told me. "If you're going to do something, do it right. Don't half-*** it, boy!" Doing half of the emissions removal will most likely just result in problems.

I know that's not the exact answer you were looking for, but, I'm just trying to keep you out of more problems.

Man, I hope you're wrong. No biggie - but damn, the tutorial doesn't mention anything about cruise control vacuum (unless I missed it)...

Re-read it. It allows for the use of CC and A/C. We're still gentlemen after all.

But if your that bent on keeping the nest, it wont hurt anything to just remove the ACV, cover it, leave the wires and **** hangin and bolt on your new RB exhaust.

Sorry RX7Carl - admitted B student. I'll go back and re-read. The CC issue was holding me from taking out the rat's nest... well, and the actual work involved.

Part of being a B student is an inherent laziness, however subtle...

Hay. I've had 2 complete RB exaust systems installed Header back w/ no problem on 81s. The rats nest was gone from 1 w/ bare bones SP in place -RB intake w/ Holley. The other kept most stock uppers w/ manual secondarys. I don't know the details but it works well.
