I guess what I mean is does anybody think this would be possible in a fiero and how different are the 3100 intake ports (98 aluminum heads) from the 3800 s/c series 1,2,3 intake ports. I guess I could make a manifold out of sheet metal. Now theres a lost art. would there be any computer interface issues (I will be useing a stock fiero ECM would I need a chip or a new ECM).

As for installing an Eaton Supercharger on a 2.8L , you would have to fabricate a custom intake manifold. I don't know if he is still around but Don Hampton of Hampton Blowers ( CA.) used to offer a service for mounting roots type superchargers on odd engines. Don has the talent to mount just about any supercharger on any engine but again I don't know if he's still in business. Fageol Superchargers makes a Magnacharger blower kit for the 60*V6 but only for carbureted or TB FI applications. So the answer is yes it has been done and can be done but the question is how much money do you have to spend vs. the cost of a solid 3800SC engine. As for another option, Rotrex Superchargers once made a certrifugal blower kit for the 2.8L but it mounted where the A/C compressor normally goes. Rotrex Fiero (Dave) once ran this supercharger but has since removed it. Supercharging with it's requirements for belts, pulleys and special mounting is more expensive to do than turbocharging. If you want boost I recommend that you consider a turbocharger as it's comparatively inexpensive and easier to do an installtion.

Dennis you always seem to find a way to mention money I dont need money only sheet metal and a mig and maybee a weekend off now thats the hard part I only get one of those a month and all 2.8 pre-made manifolds wont work with my Aluminum 3100 heads. I guess I am going to weld one myself I know it will be easy but I am just so lazy never drive for a living it makes you lazy sometimes I wish I had an electric wheelchair so I didnt have to stand
Any word on the ECM upgrades needed and I refuse to pay someone $800 to wire a 3800 s/c I will not repeat will not do a swap that involves a different ECM I dont have the smarts or the $ for EFI so it ait happenin but custom chip making I am fine with.

Shure I belive some people just about as much as I belive Well nevermind if fabracation costs a lot of money I would never have a 81 Mazada truck with a 1951 Oliver combine front end on the rear. (total cost a few dollars in rods) But what do I know I cut cut and weld on stuff all the time. I guess its a sheet metal intake then last one of these I made went on a circle track car on that note I need to get a hold of BJ and see if me still has it.

Don't let people discourage you! I want to put a series II supercharger on a 1990 4.5 L Caddy motor. I would like to know how much boost can a normal ecm take with only a mild chip reprogram. Did all aluminum head 3.1's have port injection? It would be nice to find a TBI manifold for it so that only an adapter plate would be needed. It may take a long time for you to complete your project, (mine was started around 1995) But don't give up too soon. Anything can be done with enough endurance! Please let us know how things turn out even if it's a year or two from now. Good Luck! Mark

do a 3400 swap with 3600 non vvt heads then weld up a manifold to bolt the m90 to and get a decent ecm and get it chipped to run 14psi at most and show the 3800's what a 60V6 can do with there same set up. With a turbo people have taken the hybrid (head swapping) 60v6 and made well over 300hp and 300tq using 90% stock parts so its just a matter of doing it and not letting people discourage you. If you know how to weld, fiberglass, and be creative and do your research you can do anything to a fiero or if you have enough money you can pay some one else to do it and loose out on a great experience and be able to say "I built that with my own two hands".

positive thoughts and encouragement minus the know it all aditude I allmost thought I was on the wrong forum for a second I dont see why a 3800 blower couldn't be used with the 4.5 and some fabbed intake routing or you could get a Weiand SBC blower and fab a manifold if you were willing to swich to carb. But from what people say the heads on the 4.5 dont port very far and its not the best preformance engine but I would do it anyway myself ignore the naysayers you can do it. Some people, not to name names, think that If you do anything other than a 3800 s/c swap then you are wasteing your time these get old and boring I cant wait until the next fiero dead horse motor comes out so that they can start beating it
and all 2.8 pre-made manifolds wont work with my Aluminum 3100 heads. I guess I am going to weld one myself I know it will be easy but I am just so lazy never drive for a living it makes you lazy sometimes I wish I had an electric wheelchair so I didnt have to stand
