1975 Fiat 124 Spider... Rally Fiat (Fiup)

Well I don’t need or necessarily want this car (I wasn’t looking for one that’s for sure), but I helped a guy move his 5th wheel trailer.

Total cost of delivery

  • Diesel: $86.33
  • Time: 8hrs

Includes time & fuel spent heading to the job, and heading home.

And he paid me with this car.


  • Year: 1975
  • Make: Fiat
  • Model: 124 Spider
  • Engine: 1.8L DOHC l4 (116hp??!)
  • Trans: 5 speed manual
  • Front Suspension: Double wishbone + coils
  • Rear Suspension: Solid axle + coils
  • Curb Weight: 2,116 lbs

This thing has a redline of 6500 RPM, and it looks like it had 116hp which is a bit more than I expected, I was thinking around 90hp.

Unfortunately it has some rust.

Yes that’s daylight shinning through the floor

And some more pictures

To Do:

  • Fix brakes
  • Oil change
  • Check coolant then fill or flush
  • Change spark plug wires
  • Check charging system
  • Finish vacuuming interior
  • Replace driver interior door handle
  • Troubleshoot wide open throttle bog
  • Clean out OEM fuel tank
  • Remove rear seat
  • Check trans and diff fluid
  • Replace top
  • Rewire

I’m kinda just working on it aimlessly. They aren’t worth a lot so I don’t really care to sell it but I don’t have any plans for it yet either. Figured I’d see how it drives and then go from there.


  • Add small electric motor to boost power & efficiency while maintaining the noise and feel of a manual roadster
  • Motorcycle engine swap (likely something crossplane)
  • Caravan engine swap (small all aluminum v6 with 283hp @ 6400RPM)
  • LS swap (big power, V8 sound, and good fuel economy)
  • Mazda rotary swap
  • Offroad build (kinda steat legal sand rail)

Please feel free to suggest ideas.

1st day I was mainly cleaning.

2nd day: Goal is to start and maybe drive it.

End of 2nd day: Good gravy I’m tired, but I got it started and drove it. It still needs love but I think there’s potential.

I’ve got recordings so I’ll go through those and make a video, but that’ll have to wait.

Here’s a picture.

I like how the OEM fuel tank and battery sit right next to each other.
That OEM fuel tank is full of bad gas, so I put that gas can in there and plumbed it up to the stock fuel pump. Worked like a treat.

She ran alright but when I gave her the beans she bogged hard. She’s very easy to drive though, and I think I’ll like it.


I’ve been working on the video, and I’m on my 3rd rendering of it due to me wanting to edit the first render, and the 2nd one getting completely messed up. Started fresh after that one, but just finished that one as well. Rendering now.


Its certainly interesting. Do post some more. Im always fascinated how NA people could fix up cars manually from their own garage. I certainly dont have to know how, especially the tools for these kinds if activities.

You were likely underpaid with all the effort of moving the trailer, but at least you have stuff to work on in the future. I hope it was for a friend.

Sandrailing it would be cool, esp if you didn’t care about it being street legal, you could cut a lot of corners by making it able to survive the elements. Not sure what your welding is like, working with tube etc for caging/spaceframing.

On the other hand any work you save by not needing it street legal would be undermined by the large amount of work to make it offroadable.


Something I take for granted, but it’s a very important right to me. I love cars and working on them to make something fit my needs or wants.

Actually, I’d consider myself coming off very well with this deal. If I pay myself 15hr (which if fine pay for me), then that would cost me $120, and then add the $86.33 for the fuel, which means I paid (basically) $206 dollars for it. Might as well give it away at that price. Lol

No inspections here for a car this old so I can do almost whatever I want with it and still drive it on the street, but I wouldn’t be making a frame for it. I’d lift it, put some shocks and springs on it, and through some street legal but knobby tires on it.


If it not too offensive in public, spoiler just in case FFFFFUUUUUUUHHHUHHHUUUUUUCCCCKKKKKKK YYYYEAAAAHHHH BUDDY!!!

That is very cool.

I never tried the 124, but the 147 is actually really fucking cool and is Fiat i bet is not that much different and you can fix it with gun wrapper, spit, super glue and coat hangers.

I would not mind it for the price you paid, is a great car to go to a friends house, short weekend normal fuckery like going to a restaurant/movie and shit

How do you “redo” the flooring on that vehicle? Acetylene the old one and weld a new one in? Do you guesstimate the replacement and improvise things as you go along or do you do proper measurements and stuff?

For the rust? Pretty much, you can even cut it by hand tho, is not integral for the car rigidity you can even leave it open and cover with carpet if you are a psychopath, or leave it like a flintstones car.


Hay now, lets not go calling me names :wink:

I actually mentioned to a buddy how I might end up flintstoneing it.

I’ll be taking a wire wheel to it to clean up all the rust and show me the real damage, then I’ll likely just paint it to keep it from getting worse until I feel like fixing it.

When the top goes down the price goes up.
I would try to restore it and keep it original as possible.
Because the 124 spider is still a classic.


I knew it, if you just fill with fiber glass when you sell to the not car savy person he will not be scared, is not even body colour is easyyyyyy (i mean will cost the price of the car so ye, not actually worth it)… and a Carpet kit is also really cheap, but again is the price of the car.

What i would do? Fix rust, make it drive, put carpet, if the original speakers survived i would find some tapes if is dead, i would buy some cheap crap and wait for someone to make an offer when i go put gas or something and sell it… people always make offers for those cars

I’m interested in how this turns out …

It’s alright. I won’t likely sell it and if I did I’d be upfront about everything I can remember to mention (I’d even show this thread and to do list).

I’m not scared to put more money into the car then I paid for the car.


That is very much not the case. Its a steal.

Basic angle grinder, jackstand, wrench kit, screwdrivers and a hammer. Will be enough for 9-10 activities.

Torque wrench is recommended and a friend who’s welder you can borrow.

With that and some big brain power no task is impossible.


Get cutting and welding.
Then throw in motorcycle engine.
Or do a sick lift.

Please don’t fiberglass…
Pure restoration will be just another boring moneypit.
If i got a euro every time someone told me i need to garage my cars or restore them i’d have enough money to buy said car restored…

Oh if you have any questions hit me up.
I’ve done some quite interesting stuff.
And i love carbs + superchargers + crazy car ideas.
Function over form.

Oh maybe check out Carmeets.

Why not fiber glass to fix the hole if he needs to remove the rust? maybe i bias for Fiber glass because i learned how to use it at uni, cut it patch it boom done 5 seconds, the hole i would imagine is really small, just to not get water on your foot.

And new carpet on a rust bucket looks cool as fuck tho, especially if the tape deck works…

Patching with grinder an welder will take roughly the same amount of time. Factoring in preparation.

Is stronger.

Wont rust and crust up near the edges (work for 30 years instead of 3)

Can be drilled welded to and modified in the future.

I’ve had bad experiences with bodyfiller + fiber glass fixed cars.

True, welding is forever.
I forget that people need to deal with massive changes of temperatures here temperatures are always hot as fuck, fiber glass normally holds up pretty well, way more them 3 years… i think that sudden changes of temperature that fucks fiberglass over
