My 4 cyl engine in my fiero started knocking so I was hoping to put in a new engine! I don't know what's all out there and want something very cheap and has good gas mileage. Any ideas?

Welcome to the Forum!

New and Cheap probably don't go together. Do you mean new to you or new as in zero miles? Also, how cheap? How good are you with tools, fabrication, shop space, etc? Is that all you want is good gas mileage like in a daily driver?

There are many, many possibilities depending on what you are looking for from your car. Tell us a little more and I bet you will get plenty of feedback. (You will get lots of suggestions, that's why I asked questions instead of firing off an answer)

I don't care if it's used, and good gas mileage as in a dailly driver. I love the fiero but I just need it up and running quickly/cheaply since most of my money is going into rebuilding my supra! I've never fabricated anything before but I've got decent work space.

Welcome to the forum,your probubley looking for a Camaro swap (only problem is the starter is moved).

Quickly/cheaply I understand. Go to the junkyard and get a VIN R Duke. It's gonna have high miles but it's the quickest/cheapest route to go. The u-pull-it yards up here in Detroit have several Dukes that would be an easy drop in. What year is your car? There were some differences between 84 and 88.

My fiero is an 87. And what exactly is a Duke?

thats what the name of your engine is in your fiero 2.5 litre Iron Duke

quote Originally posted by H-Dogg: My fiero is an 87. And what exactly is a Duke?

The "Duke" or "Iron Duke" is a nickname often used to refer to the 2.5-liter, 4-cylinder base engine of Fieros.

I was always under the impression that it was a very unreliable engine!

Fair-to-middlin' reliability (when new); pretty shaky now. You are stuck with about 95 hp with this motor, it is too weak for most performance modifications to be used. Your best bet is an engine swap. Look at the dozens of swap threads, pretty much any engine swap from quad-4 to LSx is possible (there was a thread about a diesel engine swap!). The 3.8 SC is about the most popular right now, but the Caddy 4.9 has a lot of fans as well. These swaps usually include swapping over the transmission that came with the engine. The only limiting factors are budget, workspace, experience level, and time (biggest factor is usually budget). GOOD LUCK!

Does anyone think that it would be possible to put in the 7MGE from an 89 supra cuz I have one laying around that just needs a new HG! I know I'd have to use a different tranny than whats made for it, do any of you think that's possible?

If that engine is an inline 6 you will have a hard time fitting it back there and the spacer to adapt a transmission to the engine is only going to hurt.

Is the 7MGE an in-line engine? I seem to recall that it was a straight six. Probably not enough room in the Fiero engine bay from side-to-side, but it might be worth measuring. You would need to do a bit of engineering to mount a transaxle to this engine. Check the length before investing too much research into this swap.

Quickly and cheap. Dont even consider a motor that has never been done.

A supra motor will require a lot of fabrication/wiring/trunk modification, which equals a lot of time and money. Your fastest and cheapest bet is getting another 2.5L and swapping it in. everything will be direct plug and play, could probably be done in a weekend if not a day, depending on skill and how many helping hands you can get. Your next best bet would be getting a 2.8L V6 and trans and wiring harness from a V6 Fiero and swapping that in.

What part of the world do you hail from? maybe someone close will have a used setup they can sell to you for a good deal. This forum is full of awesome people, and i've read threads about folks traveliing lots of hours to lend a helping hand.

I agree.

Incidentally, welcome to Pennock's Fiero Forum!

I'm in Watertown WI, we used to hold the record for the most bars and churches per square mile!

Couldn't I just weld the A frame that the engine mount to into the engine compartment than get a tranny to hook up?

You can do anything if you have the time and money. It won't be cheap and quick though. And that is only if it's not too long. Then you will need to figure out the exhaust. Then the wiring and ECM, etc. It would be an interesting build to watch.

I'm just wondering what people think! And how hard do any of you think it would be to try and fit the fiero tranny onto the 7M supra engine?

Just like Hudini said

What do people think? Honestly I dont see it happening since this was said

quote Originally posted by H-Dogg: I love the fiero but I just need it up and running quickly/cheaply since most of my money is going into rebuilding my supra! I've never fabricated anything before but I've got decent work space.

But if this gets you more motivated to do so than take lots of pics and start a build thread.

I started two build threads, One with a 4.3l vortec (never completed and $ spent)
Another with a 4.5l V-8 and 4t60 (never completed and more $ spent)
I came to the realization that I didn't have the experiance or facilities to do such a swap and bought a Fiero with a swap already done.
I'm not trying to knock you down but if you dont have the know how or experiance you may want to save some money and buy a completed swap.

Just speaking from experiance

Based on your question above, I think you may need to seriously reassess your previously stated objectives below, because where you're headed with your current thinking sounds a l-o-n-g way away from where you were:

quote Originally posted by H-Dogg: I just need it up and running quickly/cheaply.

You get to change your mind, of course, but after you've asked the people on this forum how to get your Fiero "running quickly/cheaply," I think the top-of-mind answers you receive likely will not be "try and fit the Fiero tranny onto the 7M Supra engine."

Maybe some new objectives other than "quickly/cheaply" are in order?

In any event, good luck with your project!

I'm a seventeen year old with dreams, I must sound like a complete idiot! I measured the engine and everything, it's not gonna fit and I know I don't know how to make it fit...lol I'll figure something out

Take it from a fellow 17yr old. Espcially if you're workin on a supra you're just gonna want to put another duke in, they aren't that unreliable as ecno engines, just they tend to grenade when treated like performance machines. If you dont mind throwing some money and time into it the stock 2.8V6 will net you some power gains. If you want a bit more, and throw some more cash at it you can get a camaro v6, same engine as the 2.8, just bigger. But the problem there is that you'll need a lot of parts from the Fiero V6 to make it work easily. But like the guys said. If You have the dedication, and mostly the money, you can do anything to this car

[This message has been edited by 86FieroCentPa (edited 09-17-2007).]

your best bet is to just drop in another duke, thats cheap and easy...you didnt say you wanted it to last forever lol

next bet is to do a 3.4 from a camaro, this can be done 2 ways, 1. swap ecm and wireing and whole engine, 2. use the fiero 2.8 v6 intake manifolds and...well **** you sitll have wireing cause you have a 4 banger......... swap another 4 banger or sell it or fix the one thats in it.. bottem line

If you need a 2.5 engine to get you up and running quick, I just happen to have one with 4000 miles on it. It was just rebuilt before I did my V8 conversion. I still have the papers for it too. You are welcome to it for $200.00 if you want it. I might even be able to give you a hand on the installation. You are pretty close to me also.

There's a great deal. I would take it while it lasts.

Yeah, I'll take it! Save myself the trouble and money. When is a good time for me to come by and pick it up?

Any time is okay, I only work 2 blocks from my house. I'll pm you my phone number and you can give me a call to set it up.
