I just got a 93 Park Avenue Ultra for $550 bucks. 112k miles, just did full tuneup (plugs wires, fuel filter, valve cover gaskets, cleaned throttle body, new iac, new alternator, battery, oil and filter) Car sat three years non running. Had a bad cat converter in it so it has a pipe in place. As well as a Thrush Turbo muffler. Runs good but not as powerful as my 95 PA ultra. I have a complete gen 3 m62 with throttle body, sensors etc from another junkyard 95 pa ultra. Can i swap it out in place of my gen 2 blower. My gen 2 blower is a CJ rebuilt and looks and performs like new not hardly even greasy yet was just replaced before the Previous Owner stopped driving it. Or the other option im considering is a smaller (2.2") pulley on the gen 2. I think id need to do some pcm work to get the gen 3 supercharger to work properly correct? And if so could I swap the pcm from the junkyard car i got my supercharger from right into my 93? Sorry for so many questions but i just want to get some info before i tear it apart! Thanks

I don't think anything from a Series 2 engine will work on a 93 Series 1 engine.

And there isn't much in the lines of aftermarket upgrade parts for any Series 1 engines either. A pulley might be available, but I'm not sure. Most of the websites(3800performance.com etc) are Series 2 only.

Im looking to put a 95 series 1 supercharger setup on my 93. My 93 has the smaller throttle body and non epoxy coated rotors whereas the 95 has the expoxy and larger throttle body. Or even just put the rotor pack inside my 93 supercharger, if possible. I have everything (maf, iac, tps, throttle body and supercharger from the donor car) to swap my older style.

I'm not familiar with any of the Series 1 engines, so I couldn't tell you if any parts would swap over except for the 95 sensors are OBD 1.5 and may not work well in a OBD 1 system.

If your going to do that much work, why not a complete Series 2 transplant? Upgrade parts are plentiful with the Series 2.

From what I understand, the swap is possible, but tuning is a nightmare. It is not plug and play. Those that have done it have never been able to get it to run right, just good enough. There is also the computer concern, as they are not compatable.

Ok its looking like id be better off just swapping for a 2.2" pulley on my existing setup. It will be plenty fast then id think.

That seems like a pretty big leap from the standard 4" pulley. You need to have a way to scan for KR or your going to cause some serious damage. Best way to prevent that would be to get an intercooler for the */C. And I don't know of anyone that makes an intercooler kit for the Series 1.

Well, you should scan for KR, but I believe that era starts pully diameters at 2.5" or so.

You don't want to go much smaller anyway, I think the 2" is red lining the supercharger, and anything smaller than that you don't see any gain, because all it is doing is generating heat.

Also, with mods, plan on dumping money in the tranny. Series 1 is notorious for shredding differentials, especially when you start modifying. All that torque has to go somewhere.

I had it hooked to a scanner the other night and it was reading 0 KR. So ill get the new pulley. Will I need a new idler to compensate for the slack in the belt?

You need to monitor for KR after you install the new pulley.
