Can anyone name all the cars off the bat that are compatible with a fiero

another fiero.

You may have to further refine your question.

like if i wanted to swap my engine with a more powerful engine like a 3800 or something just all the types of cars that have compatabile engines

If you're doing a complete swap, anything is compatible depending on your motivation.

With the 3800 or V8 swaps, you have the benefit of an already considerable community and conversion parts supply.

Some info on 3800 donors here: https://www.fiero.nl/forum/A...060811-2-072137.html

Easiest swap I would say is a 3.4L pushrod out of a Camaro or Firebird from the early nineties. Same bolt pattern for mating the transmission, drill new holes and tap for relocating starter to the other side, and put the intake from the 2.8L Fiero engine on. It runs on the stock 2.8L computer, gives you a modest boost in horsepower and torque over the 2.8L and looks completely stock.
The 4.9L Caddy engine bolts right up to the Fiero transmission, but requires more wiring modifications, an exhaust system built, and figuring out coolant piping.
The L67 3800 supercharged engines require even more wiring modifications but there are companies out there that have some mounting solutions already.
A thundering V8 can be crammed in with Archies kit from v8archie.com
The 3.4L DOHC engine can be made to fit, if you have an '88 cradle it uses the stock v6 front engine mount and there are solutions on several sites for the rest of the mounting. You will loose your passenger side decklid spring mount and have to use gas shocks to hold your decklid open though since the engine is so tall with the DOHCs.
Just about any engine you can think of could be made to fit. Play around with some searches and you'll find plenty of interesting swaps people have done or have started. A good place to really be inspired is in the Construction Zone were most of the best builds are. Lots of talent on this forum. Basically, you're only limited by your talent or your wallet. Or how many people owe you favors...
Best of luck in finding what you're looking for, but remember to document anything you learn and share with the group so the forum will get better.

Other than another Fiero, none are direct swap outs; even the F-body 3.4 pr engines require a few mods. It depends on you expretise etc. Thus, are you looking for only easy swaps?

Ok just to let everyone know i have a stock 84 cradle and don't really have funds to upgrade. I just want a cheap upgrade from a duke that needs an engine rebuild and has 103,000 miles on it. I just want something easy and cost effective cause i am just a kid fresh out of high school.

Ouch, well, since it's an '84 any engine swap, other than another duke, would be more involved. The wiring harness was different for the initial year and any other swap would involve wiring changes plus whatever other modifications are necessary. And being out of High School and I'll bet on extremely limited funds, you're very limited in performance upgrades. Been there before. My duke didn't need a rebuild though. I just gave it a really good tune up, lots of TLC and she ran just fine and plenty fast enough to still have some fun at SCCA autocross events.

If the duke is worn out, another duke in itself would be an upgrade. Swapping will cost money I don't care how you go about it. Rebuild or replace what you already have with another duke.

I will be turning this car into a winter project and doing some conversions like a fast back conversion with gt front and rear fenders with dual exhaust which i got from a junk yard and i am planing on giving the car a whole new paint job this summer along with some kind of speaker system since I'm not a big fan of the head rest speakers and i am hoping to find a nice grey seat that has no rips at a junk yard to replace my driver seat that has rips. Before i do all this though i need to figure out this whole engine thing.... I will be creating a build thread to once i get started. Oh i also have to finder a dash to replace mine it has a couple rips and stuff. Also does anyone know where i can find the parts that creates a wind tunnel for a 1986 fiero gt bumper i have the bumper on but the radiator isn't getting the air it needs to keep the car cool and my radiator is expost. Mine did come with them but they where all torn to pieces.

I will have to look, but there is a list here on the forum, where it discusses which 4 cyls are a direct replacement. Did you try a search?

A "complete" engine means cylinder block and heads. It does not include accessories such as alternator, water pump, A/C compressor, etc., although some of these parts from a donor engine may coincidentally fit the Fiero.

'84-86 Fiero 2.5L Engine: Is the same as:

Pontiac 6000 '84-86 2.5L VIN "R"
Chevy Celebrity '84-86 2.5L VIN "R"
Buick Century '84-86 2.5L VIN "R"
Olds Cutlass Ciera '84-86 2.5L VIN "R"
Chevrolet Citation '84 2.5L VIN "R"
Olds Omega '84 2.5L VIN "R"
Pontiac Phoenix '84 2.5L VIN "R"
Buick Skylark '84-85 2.5L VIN "R"

'84-86 Fiero 2.5L Engine: The following engines can be used in a Fiero if injector and carburetor are switched, vacuum pump hole is covered, and distributors are changed. (These engines do not have the coil in the cap and they use a different distributor gear.)


Chevrolet Citation '80-81 2.5L VIN "5"
Olds Omega '80-81 2.5L VIN "5"
Pontiac Phoenix '80-81 2.5L VIN "5"
Buick Skylark '80-81 2.5L VIN "5"

'84-86 Fiero 2.5L Engine: The following engines can be used in a Fiero if the vacuum pump hole is covered.

Pontiac 6000 '82-83 2.5L VIN "R"
Chevrolet Celebrity '82-83 2.5L VIN "R"
Buick Century '82-83 2.5L VIN "R"
Olds Cutlass Ciera '82-83 2.5L VIN "R"
Chevrolet Citation '82-83 2.5L VIN "R"
Olds Omega '82-83 2.5L VIN "R"
Pontiac Phoenix '82-83 2.5L VIN "R"
Buick Skylark '82-83 2.5L VIN "R"

'87 Fiero 2.5L Engine: The following engines can be used in a Fiero except for the flywheel or flexplate. Change induction, exhaust, and electrical systems, pilot bushings as necessary. Will not interchange with '88 engines due to oil pan interference with frame.

Pontiac 6000 '87 2.5L VIN "R"
Chevrolet Celebrity '87 2.5L VIN "R"
Buick Century '87 2.5L VIN "R"
Olds Cutlass Ciera '87 2.5L VIN "R"

The following information was posted to Pennock's Fiero Forum by "Ray" from Houston, TX:

It is possible to get a better 2.5L engine for the '87-88 2.5L Fiero from a 1993 S-10. The 2.5L engine from the '93 S-10 should provide over 100 HP and considerably better mileage.
'88 Fiero 2.5L Engine: The following engines can be used in a Fiero except for the flywheel or flexplate. Change induction, exhaust, and electrical systems, pilot bushings as necessary. Will not interchange with '87 engines due to oil pan interference with frame.

Pontiac 6000 '88-89 2.5L VIN "R"
Chevrolet Celebrity '88-89 2.5L VIN "R"
Buick Century '88-89 2.5L VIN "R"
Olds Cutlass Ciera '88-89 2.5L VIN "R"

'85-88 Fiero 2.8L: The 2.8L Fiero VIN "9" engines are unique. There are no other automobile engines EXACTLY like these that can be dropped into a Fiero. However, other engines will fit with minor modifications noted below.

The following engines can be used in the Fiero by changing the intake manifolds, exhaust manifolds, fuel delivery system, and removing the power steering brackets:

Pontiac 6000 '82-84 2.8L VIN "X" & VIN "Z"
Pontiac 6000 '85-86 2.8L Two-barrel carb VIN "X"
Chevrolet Celebrity '82-84 2.8L VIN "X"
Chevrolet Celebrity '85-86 2.8L Two-barrel carb VIN "X"
Buick Century '82-86 2.8L VIN "X"
Olds Cutlass Ciera '82-85 2.8L VIN "X"
Olds Cutlass Ciera '86 2.8L Two-barrel carb VIN "X"
Chevrolet Citation '82-84 2.8L VIN "X" & VIN "Z"
Olds Omega '82-84 2.8L VIN "X" & VIN "Z"
Pontiac Phoenix '82-83 2.8L VIN "X" & VIN "Z"
Buick Skylark '82-84 2.8L VIN "X" & VIN "Z"
Buick Skylark '85 2.8L Two-barrel carb VIN "X"

'85-88 Fiero 2.8L: The following engines can be used in the Fiero by changing the intake and exhaust manifolds and removing the power steering brackets:

Pontiac 6000 '85'-86 2.8L EFI, VIN "W"
Chevrolet Celebrity '85'-86 2.8L EFI, VIN "W"
Olds Cutlass Ciera '86 2.8L EFI, VIN "W"
Chevrolet Citation '85 2.8L EFI, VIN "W"
Buick Skylark '85 2.8L EFI, VIN "W"

'85-88 Fiero 2.8L: The following engines can be used in the Fiero by changing the intake and exhaust manifolds, drive belt system, and removing the power steering brackets:

Chevrolet Cavalier '85-86 2.8L VIN "W"
Cadillac Cimarron '85-86 2.8L VIN "W"
Olds Firenza '85-86 2.8L VIN "W"

NOTE 1: A popular swap for the Fiero 2.8L engine is a 3.4L engine from a '93-95 Camaro or Firebird. This engine requires simple modifications that are beyond the scope of this manual. Other popular swaps are the Chevrolet Small Block V8 and the Cadillac 4.9L V8. For more information check v8archie.com and thefierofactory.com.

NOTE 2: New engine mounts are appropriate when replacing an engine. The 1988 mounts can be expensive. Robert Lachance advises that you can use the front engine mount from a early '90s Pontiac Transport 3.8 (non-supercharged) on a 1988 2.8L Fiero engine for about $100 less than the Fiero-specific mount from parts stores. No modification is required. We don't have the part number at this time but Robert reports the mount is available from GM dealers. If anyone can provide the part number, please let us know.

Just wondering from the engines above would any of the 4 cylinders have a better chance for upgrading of expansion...????

What do you want to do? I would recommend sticking another stock 2.5l in there and then work towards a V6 conversion of some sort. Any mods you do to the 2.5L just won't be worth the effort. The 2.5l is for gas mileage.

Ummm about how much would it cost me for a v6 upgrade
I mean cause 1 i am not rebuilding an engine myself i am sending it off to be rebuilt and 2 I am not taking out the engine myself cause i don't have the tools and my uncle said he would take it out but i have to pay him....

[This message has been edited by Robbie D (edited 07-19-2011).]

thousands of dollars... I think people here were taking $4-5K since you have to pay labor. Based on the state the car is in, you would be better off buying a converted fastback, if that is what you want.

Ummmm if I was doing a six cylinder upgrade i would probably ask my buddy who owns an 85 to help me out so i don't have to pay for the engine to be removed
He knows hwo to remove engines but with my uncle he knows someone who rebuilds engines for a life so there are ups and downs to everything.

You have an '84, so you will have to change more things than an '85-88. Do some searches to learn more of what is required to convert an 84 to a V6.

Ok will do i know you have to do some rewiring and stuff to it in order for the engine to work i probably will just stick with my 4 cylinder and i will rebuild it and somehow make it look nice alot of people are putting my car down....

You would probably be better off just buying a running 85-88 V6 car, if you're going to have to pay for labor and parts to do a rebuild.

You will have to replace the entire engine wiring harness, computer, fuel pump, some hoses, rear springs, fuel lines, guages... and a few other things off the top of my head. As for the people putting it down, they still will find a way to say something. Just make it the best '84 you can!

That the plan right now I mean make it the best 84 i can...

Word-up. The 2.5 is a bad engine to try to build up because of weak mains, thin head, and small runners. It just has no potential for anything over 120hp and THAT will cost you huge bucks to achieve.

The Fiero was designed to accept the V-6 and a 2.8, 3.1 or 3.4 swap is not hard to do and the power gain is noticable.

Well, as mentioned, it is a fair bit harder to do on an 84. For all the parts you'd need (without fabrication), it would probably be cheaper to just buy a running 85-88 V6 car. If you're going to swap to another engine that doesn't directly mount up in the Fiero, then it's not as bad in the 84, since you're going to have to fab mounts onto the cradle anyway. The wiring isn't as great to deal with, but it's probably easier to do a 3800 swap in an 84, and do it right, than a stock-looking 2.8/3.1/3.4.

But it still will be a couple grand for a 3800 swap wont it??

quote Originally posted by Robbie D: But it still will be a couple grand for a 3800 swap wont it??

Probably, but it's going to be that for any year. For the stock 2.8, you'd need parts from an 85-88 car to make it work right, and for all the parts you'd need, you could probably just buy a running car. You could buy a running 3800 swapped car, but it will probably cost a bit more than a running 2.8 car.

Just wondering would a 3800 fit in a vin-c fit in a fiero it has 112k miles on it and will cost me around $450 for the engine

VIN C on what? If it's a 3800 it should fit. If it's an old school 3.8 that was in the 80s GN, it's a bit more work, and not as nice as the new 3800s. If you're really looking for a 3800, what you want to get is a Series II or Series III engine.
