In a Fiero with an LS4, if you look really hard, is there room for a Procharger?

Depending on the water pump you use, how your alternator is mounted, and if you have an a/c compressor run by the engine too, it could be possible.

A small turbo would be much easier to do, though.

Cantilever it off the front of the engine in the battery tray area or use a jackshaft (like the magnachargers) to drive the procharger mounted off the rear of the heads (over the transmission).

dobey, I am just not a fan of turbos. I will be doing a dual exhaust so it would be TT.

fieroguru, I believe that you have an LS4 Fiero? Or have done a swap? The jackshaft may be a way to go. Routing the air would be interesting. I was planning to use the upper part of the trunk for an after cooler.

Will, Yeah, I think it would be fun. Maybe you can pick me up a blem from the factory.

Correct, I did a LS4/F40 swap to my personal Fiero.

It will be an LS4/4T65E-HD.

So you think that it is possible?

If I go ahead with this project I would like to have the Procharger mounting and placement already determined to avoid doing something that will make it difficult or impossible later.

Thanks,

Steve

I certainly think its possible, but it will require extensive design and fabrication for either method.
There is quite a bit of room to work with in the engine bay:

correct me if im wrong but I seem to remember someone trying to put an LS2 manifold on an LS4 and it wouldnt line up and didnt fit. Was that you Fieroguru? I remember you working with the LS2 intake or trying too anyways

Several LS4's are currently running LS2 intake manifolds and the picture of my LS4 shown above has an LS2 intake on it as well. They can be made to fit and how much work that takes really depends on if you plan to keep DoD or not.

The picture you're referring to had the intake sitting backwards. They fit just fine after a small modification to the oil pressure sending unit boss on the valley cover.

Edit: Found the image you were talking about:
