I very good friend of mine died a few years ago and left behind a 1985 GT Fiero. He always wanted to swap the motor and make it fast. His family is moving and offered to give it to me. I have a turbo accord I built a few years back, that has developed a electrical issue I just can't figure out. So i have two options, pull the dash out of the accord and redo all the cars wiring, or swap my engine setup to another chassis. The accord is starting to get real junky looking, and spinning the front tires gets more lame every time I do it, and I've been looking at chassis that I can switch to. So I'm thinking that Its time to start on my next project.

I read somewhere that someone had already done a H22 swap in a Fiero, can anyone tell me where that is?

Now for a little of my history, and a little about the setup I wanna swap.

My accord:
The videos were shot before I put it on the dyno, running a street tune @ about 15 psi

And for the dyno:

These numbers are uncorrected and it was over 100° that day.
17 psi:



I've got a lot of design, machining, and fab skills. I should be able to fab what ever I need to finish the swap. FYI I also tune Motec, Ectune, Hondata, and Chrome.
Here's some of the other projects I've done.

Ill start with my CNC.



Here are a few things I have made on it

I also am a part of a FSAE team. Here is our car.
check out this video




Here is a header I built.

i don't thinl that there is anybody on here that has swapped a honda motor in the fiero but i know there is a nissan motor swapped fiero done. looks like you have the skills to make the mounts. The only thing else you would need is the wiring. some people on here will tell you to just do a gm motor swap but it is your car and i say do it your way

Whoah! Where the hell did you come from? You definately have skillz mi amigo. Welcome to the forum, and that is a grand thing to do to that car. Awesome story, glorious pics, and much to offer.

Best intro to the forum I ever seen

I've been on a couple honda forums, and realhomemadeturbo. I do more lurking than posting. I'm pretty excited about this project. Hopefully it will be on the road before fall.

Very cool!

I also built my own CNC machine, comes in handy!

It wasn't yet complete at the time of this picture



I hope you get the swap to work out, always nice to see fresh ideas come to fruition.

Not to sound like a hater or anything... I currently drive a turbo fiero and a turbo crx with a built motor... and I would never consider putting my Honda motor into a much heavier car. I wiuld imagine transmission problems will start popping up and the power to weight ratio really is a drag when you are used to trapping in he 12x range in he Honda... basically what I arms saying is you can do a turbo 3800 setup easier and cheaper than you could swap the Honda motor in for... and have stronger parts across the board.

Defiantly a project worth doing! Good luck with it! The intercooler mounting will be interesting though.

Sweet cnc. Thats a nice car in your sig. Cars like that are part of the reason I am excited about getting one.

I will be loosing weight as my accord is about 3000. And getting RWD!

I will be using a water to air setup, no big FMIC.

I remember when i thougt a fiero was ligter than a honda... sadly reality sets in and you realize you have an impossibly small car that weighs more than a camaro.

The water air setup works well in a fiero. I run the ebay cores and random junk radiators in the front with good results for cheap.

Welcome aboard.

You will be the pioneer for this swap. Good luck with your project.

curb weight of a new camaro ss 1LE is 3878lbs .thats a 1000 lbs more than most fiero's .i doubt that even a 69 z28 tilted less than 3300 but i would have to look it up .

According to camaros.net it weighed 3296.

4 lbs out not too shabby for a guess .anyway i think the idea of this thread is great .i like the idea of all aluminum 4 bangers in a fiero .i use an ecotec but i own a honda too and they make great motors .so good luck with the swap and welcome to the forum .you are using the honda 5 speed manual with this swap ?

Not bad at all. Now, back to the topic for me as well.

I once heard that Honda engines spin in the reverse of other manufacturers. If this is true, a Honda gearbox would be essential.

i just confused myself with this post so i have edited to say : some hondas have the tranny on the passenger side , some are on the drivers side .so some could bolt to a fiero transmission but a lot would not .but to get the most out of a honda , you need the gear ratios that a honda tranny has .hondas are designed to rev higher , so the ratios are designed to let them rev .a fiero or any GM transmision would leave them without much grunt on the bottom end .

A few guys in town here have some similarly race minded camaros/mustangs that are lighter than my race fiero. Curb weights are good guides but when the dice hit the table its a different story.

I don't get it. A S2000 (the original car the F22 was in) weighs in at 2,800 lbs, about the same as a Fiero. It has about 240 HP stock and revs up to 9,000 RPM's. putting a turbo on it can and has doubled the output of this motor, with supporting mods, and having that available RPM range for a turbo is ideal. Why wouldn't this be a good engine for a Fiero again?

If Camaros can be made lighter, so can a Fiero. Honestly though, you wouldn't really need to. Unless he's going to try to be majorly competitive with his car, it doesn't really matter. In all honesty when I saw that they were using NSX transmissions, I had planned on doing a full NSX swap, but once I saw what they wanted for the used engines and factored in the difficulty finding anyone to take it on and getting all the parts I needed I decided on the 3800.

Dark... pizz in another thread. This guy is obviously quite skilled, and appears to be quite knowledgeable. Let us just sit back and watch/learn.

Of course AFTER I posted I realized that we are talking about the Accord F22, which was a SOHC IIRC, and only had about half the HP of the DOHC versions. Which F22 are you working with here?

Meh, its just advice from someone that is into hondas as much as fieros.. I am not "learning" anything from "this guy".

I would hate to spend 3x the time and at least 3x the money on swapping in parts inferior to stuff you can get from a junkyard for nearly free only to be disappointed with the end result. I hate to see the advantages that the honda motor package offers wasted on a fiero, and the labor swapping the fiero wasted on putting a small motor in is all. Call it being a hater all you want, but I really dont care what anyone does either way, I just thought I would offer an opinion from a source of someone that has been there.

i don't know if dudewithout fiero and i are thinking of the same person (haven't been hanging out here as often lately), but the person i remember working on the nissan swap started out trying to do a honda engine first. i met him once, but i can't remember his user name right now. if i do i'll stick it in later so maybe you can look up his old thread.

edit: brocephus. had to go to a local forum he was on more. it think there was some write up on it there too. louisvillestreets.com

I think your missing the point. I'm not trying to build a race car here, when I want to build a race car, I work on the Formula car. This is just to have a cool, fun, unique car that I can enjoy on the street, and take to the track every once in a while.

Don't let them annoy you. If it's not a turbo 3800 they dis it to no end. They just don't seem to realize not everyone is trying to be the fastest in a 1/4 mile straight line.

Good luck on the swap. I look forward to seeing the progress!

Maybe I'm reading things wrong, but he already has the engine setup and is just going to be pulling it from his Accord and dropping it in the Fiero. Okay, so it's not a direct drop-in, but what engine swap is? If he's got the time and tools to build the mounts needed and setup the ECU - go for it!
What's so different in this vs people swapping the Duke for the 2.8, or the 2.8 for the 3.4, 3800, LSx, SBC. Heck, people even go from the 2.8 to an Ecotec; so I guess this swap is more like that. Sure it's getting away from the GM/Chevy line - but it should still work.

Dbsharp - Do your friend proud. Now get to work and take lots of pictures! Hopefully a paintjob too.. I look forward to your progress... another swap/build thread to watch.

am i the only one to read the dyno sheet posted above on this motor ? i know how fast my car is at around 220 hp , this build is going to be killer fast .cant wait to see it done .

quote Originally posted by wftb: am i the only one to read the dyno sheet posted above on this motor ? i know how fast my car is at around 220 hp , this build is going to be killer fast .cant wait to see it done .

Not the only one. I looked it over and it looked pretty good to me. Torque and hp crossing over about 330 hp mark, looks like hp tops out around 375., it's hard to read those little numbers at the bottom of the pick. Not to bad at all "thumbsup:.

quote Originally posted by Xyster: Not bad at all. Now, back to the topic for me as well. I once heard that Honda engines spin in the reverse of other manufacturers. If this is true, a Honda gearbox would be essential.

Some do, but not all. Mostly only the older (pre-2000) engines like the B series. The K, F, and H series are all standard rotation.

I really didnt want to have to explain this.. but here is why a honda swap is SIGNIFICANTLY harder (than any GM swap, not just talking about the 3800 here, as you have noticed I have yet to say anything specific to a 3800)

1. Axles. building a set of 400whp axles that work correctly will be more or less impossible.(short of $1500ea custom jobs) You could try a respline job on the honda axles if they are long enough to adapt on the fiero outers. If you dont do that, you dont have the option of swapping outer hubs, you may be able to respline the inner tripot end if the honda tripots work the same as the fiero axles.
2. Mounts. The honda motors are 100% designed to be mounted on from the top down, while all GM mount systems operate from a bottom up system.
3. Gauges. No fiero gauges other than tach would work.
4. wiring. A honda motor/ecu is desinged to work with a "main relay" that would have to be integrated or bypassed... its not hard but it basically doubles the wiring job over any gm swap.
5. turbo. The H22 mounts the turbo in front of the motor.. which "may" work i am not sure, but my guess-gniering says that the turbo is a few inches passed the firewall. Either way the c203 and c500 connectors will be extremely close to the ramhorn.
6. Clutch/shifter. I dont think that the accord used a cable clutch, so you MAY be able to use the fiero clutch system if you are lucky... THe shifter on the other hand could be impossible to swap in if it is anything like my CRX. The shifter is designed to be directly connected to the shifter via 2 shafts that are directly behind the trans.... It would take thousands of dollars worth of time/engineering to come up with the right conversion parts to use something like my crx trans in a fiero.

then, you have to rebuild the entire turbo kit.. yay.

Yeah, it's a hard swap to do. But in the end it'll be awesome. And in the end he can say he swapped a honda motor into his fiero. I've seen some weird engines in fieros, heck i'veseen a 454 big block in a 63 VW bug. It was 4 wheel drive too in would destroy all 4 tires under half throttle. It's totally possible and I cannot wait to see it when it has been completed.

Define awesome.

quote And in the end he can say he swapped a honda motor into his fiero.

I wouldnt admit that to anyone.. honda guys will be confused, domestic guys will be thinking what I know, fiero guys dont exist in reality.

FYI, dark lives in his mom's basement. It is easy to judge from the comfort of the coddeling. Look up his builds. While extremely fast, they barely make it out the driveway.

i had all of the same problems with my ecotec swap , except i did not have to make axles .the trick is not to use any of the fiero electrics except the lights and radio etc. i have a cavalier guage cluster , i have a cavalier wiring harness and ECM and BCM .the computer from the fiero is not even in the car nor is it needed .my ecotec motor mount is on the top as well . three pieces of metal welded to the cradle , drill and tap 2 holes and the cavalier stock rubber style motor mount is in a fiero . the dog bone is on the bottom of an ecotec , also barely a challenge .four more pieces of metal welded and you can use the stock cavalier rubber transaxle mounts , again no challenge at all .i think of the fiero as more of a frame to mount stuff in rather than a whole car .i consider most of the drivetrain and suspension that came with the car to be junk that needed improving on .nothing that connects my car to the road is stock . i dont see any unsurmountable challenges putting a honda engine and tranny in a fiero .it wont even be the first GM car to have a honda in it .the saturn vue came from the factory for a while with a honda V6 in it .honda will sell motors to any company that wants them .

Welcome to the forum Dbsharp. I'm looking forward to seeing how you tackle the challenges that lay ahead. It looks like you've got the tools, skills, and know-how to pull it off. Whether it should or shouldn't be done is nobody's business but your own. Please don't let the negativity of the few discourage you from posting your progress for the majority of us who are interested.
