  • Fiat 126 conversion.

    After having been offered a 126 by merrescmitt owner i've been doing some research on the car itself and need some help if anyone can give it to me.

    Due to it being a 126 bis - the water cooler jobbie- the tunning potential is pretty much nil- an exhaust is possibly the only thing do-able.

    Now my thought is, or rather my situation is, my significant other doesn't have any transport at the moment. She's limited to having a fairly new car- don't ask... its complicated (lol), so she'd have the clio if i could get decent uni transport. So I have had a night of deep thought. Meshescmitt owner was saying that there was room to stick most engines in there- from cinq 900's to 1.1 sporting's so i got to thinking- if theirs that much room would it be possible- even feasible to transplant a gen 1 600cc lump from a mk 1 or early- single 02 sensor smart with gearbox and all into it?

    I'd like to go for a smart enigne as I'm getting really fed up of having a manual gearbox again, traffic in leeds is awfull so an auto would be great- I know that they're flawed, but they do what I want them to do!





    This is roughly what a 126 looks like- with the engine placed way out back.



    A lovely libray picture of the polish fsm 126's



    Right- thats an aircooled... (i think!) 126 lump- give a fair idea of size.



    This gives a fair idea of the room that i'll have play with.

    As per usual I really don't want to pull my finger out of my pocket more than needed, but i do recognise the need to have it done properly. Does anyone know of anyone who could possibly do this?

    I don't want a mad arse racer, but i would quite like a fairly swift everyday car that makes me smile, that gives me the same feeling as the beast did when tooling around leeds!

    I don't want to start ringing round yet as its only pie in the sky until i have a. the car, and b. the engine.

    I have thought about z-cars (the guys that did the smart/bike conversion for the likes of BIG and SRU, or possibly asking ian for advice (not that i haven't bothered him enough in the past with pointless phone calls!). Can anyone help me?

    Many thanks.

    thought you wanted a V8

      Yes but a v8 on a student loan is very hard to pay for... I know that with the right treatment smart engines are one of the best engines for inner city driving, they use next to no fuel, are fairly quiet, and have good tunning potential.

      The 126 is a small car as standard, so sticking a v8 up its arse would mess with the pin sharp handling, and would screw the dynamics of the car up, rendering it a weekend play thing. Not really what i want... right now anyway.

      V8's are all well and good for the days when money is not a problem, but a V8 is not really that useful when it comes to driving around leeds, or insurance for that matter. Plus i'm a school teacher, so after a day at work, i think that a big / small block might drive me insane.

            Everyone had dreams......even the tuners....how do you think twin turbo brabus roadster came about.

            maybe one of the best thoughts by any tuner for a long time is on front page.


            Oh how the usual drive would be fun.

              would the ECU not go bananas? or is that why you mentioned a mk1 smart? [is the computerisation on the earlier ones not as reliant?]

              the 126 has even got an air vent on the side for the scoop!

                Re: Fiat 126 conversion.

                the reason i mention a mk1 is that the mk1 had no lambda sensor at the cat- and as the 126 is pre '95 it needs no cat. Also the mk1 lump is more tunable- I could get rid of the tik pipe and just hard bolt a k&n filter straight to the turbo- nutty spool up speeds.


                Yeah, the 126 also has the side scoop- i looked into one before i bought the smart- I wanted a go-cart really.

                  this is a watercooled - sits much lower down as it is a flat twin and with box at back. That's to accomodate the hatch that was fitted to the bis.

                  this is the engine bay complete with engine fitted
                  http://i18.ebayimg.com/01/i/05/f8/2f/71_12_sb.JPG

                  Don't know height of lump without checking but there's a bit of a difference between it and a smart lump. width of car is about the same. It would be easy to fabricate a new hatch with extra height if needed. It would be worth exploring fitting a whole Smart rear subframe although you would need to stick with 13 or maybe 14" wheels. The car could also cope with sitting higher up at the rear if needed. yes it does have an air scoop - which is used to cool the radiator at present. All the controls underneath run up the middle of the car. A little more space could be made my moving the fuel tank from under the rear floor pan to the bonnet area as well (like the original 500s).


                  mounting points for engine are (from memory) at back and front on to the bodyshell. Engine itself probably weighs a wee bit less than a smart one just because of the lack of turbo and much lighter exhaust. I'd say that there is plenty space at front in boot to accomodate a radiator with a blanking panel behind - the front panel would just need vented with some means of escape for the hot air too. Would have the same kind of weight distribution as the Smart but much much better handling - with the option to have four seats and the ability to park anywhere.

                    Re: Fiat 126 conversion.

                    Before I start, I have no idea what I'm talking about with the technical side of this!

                    But would it be easier or harder to put the whole mechanical back end, including the axles, gearbox and suspension, into the 126? Like what Ferrina has done with an MR2 back end in his Smart. I suppose it would depend on whether the Smart is a lot wider than the 126.

                      That engine bay looks familiar...

                      Perhaps it won't be as much work as i'm thinking it would be.

                        The photo of the BIS is exactly what the car will be like- not as the photo in my first post.

                          I'd be inclined to agree!

                            i'd be looking at swapping the whole back end over as well. Its going to turn out to be rather expensive and fiddly to do though.

                            You need to find a mk1 smart, and get the rear sub frame, engine, gearbox, turbo, exhaust, ecu, fuel pump, axle, drivshafts, speedo / instrument cluster.

                            I'm not too clued up on the 126's but what is their rear suspension setup like? You mentioned about a big engine screwing with the handling but moving toward an active rear axle (assuming it doesnt have one now) is going to cause handling 'changes'

                              AFAIK suspension is independent coil springs and shockers bolted to inner rear wing top - again - it is easier to totally remove the rear end of the fiat in one go rather than try and take the engine out on its own.
