I was thinking of supercharging it with either a Eaton or Vortech Supercharger anyone know of a kit for this app, or would I have to Fab something up by my self, and how if anyones done this sort of thing?

oops. double post..

As a former Duke owner, I must ask one question: Why?

Cooter, I was wondering the same thing..

I think it might be cool to buy a cheap 84 coupe..take the duke out, sell it for parts/whatever.. and buy a turbo 2.0L 4cyl from a sunbird or something.. I'm not sure how easy it would be to retrofit into a Fiero, but it might be a fun project!

Because I thought it would be neat and what other ways can you increase hp in the Iron Duke? other than Nitrus, turbos, Overboring, camshaft ex.,and underdrive pullies?

ALRIGHT GUYS, I am going to have to go with baldlobo on this one. NOT VERY MANY PEOPLE even TRY to supe up our little Iron Duke's, while almost everyone try's to "swap" out our little engines. DON'T GET ME WRONG, I would love to swap out one of my 2.5's for a 3.8 supercharged ANY DAY. But that is the obvious. I give MUCH PROPS to baldlobo for his interest in the Iron Duke. I too am going to SUPE up one of my Iron Duke's (84 SE)!
You guys MAY flame me but, hey, THIS IS MY STANDING IN THIS.
MORE POWER TO YOU BALDLOBO!!!!

87 Coupe "IRON BEAST"
84 SE (project)

No harm intended, just curious. On my Duke, I added a GT muffler, MSD 6al, GM blaster coil and gutted airbox. If nothing else, it got over 30 MPG after the modifications.

I defense of the 'iron duke,' the light weight of it allows for great handling. I've owned three 4 bangers, rebuilt the 2.5 engine 3 times and know it well. About a year ago I finally upgraded to an 87Gt and would never go back to the 4 banger, but one shortcomming the 2.8 has that the 2.5 does not, is overall weight and more noticeably, weight distribution. The 2.8 gt is still damn good, but can't hold a candle to the 4 banger. I could throw my old 4 bangers into semi-tight freeway transitions at 90+ indicated MPH and not even get a wiggle or feel in danger. My 2.8 feels quite a bit heavier than my old 4's, even though the differences are slight. With stock set ups, I would never throw my 2.8 into like corners at like speeds. Being an aviation guy and a GSXR guy, I place much importance in removal of weight with the consequence of loss of HP. I agree with a previous member who alluded to a high performance 4 banger instead of upgrading to a 6. Most auto drivers or car enthusiasts never push their cars to their latteral G limits, hence don't care about a little added weight. When you road-race people on the street, you'll find that most of them are scared to death of corners and slow down more than neccessary, only to roll it on the straights. Corvette squids are noted for this behavior and it nausiats me. Anyone who knows aything about road-racing, knows that the race is won in the corners. With drag racing, it's obviously won in the straights.

The moral of this long story is that although the 4banger is pathetic on the HP end, the handling is superb.

thats the appeal of the 4 cam v6 to me. i don't know by how much but i've read it's lighter than a stock 2.8. maybe with battery relocation and wheel/tire upgrades handling might still be as good or nearly as good as with the 4 cly.

if nothing else maybe a quad 4 swap. with it's higher redline it would probaly take better advantage of a turbo anyway. i think id have a hard time convincing myself to go through all the trouble of a swap just to put in another 4 cly. though, unless i could do it really cheap.

A quad 4 with a turbo and intercooler can make 350 hp. Reliability(head gaskets) become a problem though. I have heard that many auto cross Fiero's use the quad 4 because it is so light and responsive and can make descent power.

Come on people I'm not asking for much just some help and no I'm not changing the bloody engine out I like the Iron Duke!!!!!

You are not going to find much help on making the Duke into a powerhouse. I have not seen many "over the counter" performance parts specifically for this rather lame engine. A header, performance exhaust, ram air type scoop, ignition box with coil and maybe a cam will be about the best you can do. Because you have the 84, it is a flat tapppet cam and a better one is not hard to find. The Holly intake and throttle body will be an improvement, but I dont know by how much. People have told me that the bottom end of these engines is the weak link and they dont like to turn the engines up very high. Go ahead and buy another head, have it ported/polished and decked. Match the intake to it. Get the header. More air in and out= more power! Just dont run it lean or piston death may end your day early.

Have fun!

what about daul holley tbi, i seen them on a iron duke forget the web site though. i check the holley web site and could not find the intake,maybe someone here may know. hope so, i like my iron duke too.
