I would like to introduce The project I am working on. I am trying to fit an Toyota Aygo engine (1KR-FE) including gearbox in a Fiat 126. I tilted the gearbox to get the drive shafts in front of the engine. My main goal is to keep the Fiat as 'original' looking as possible, maybe try to achieve a cleaner look. Piet
Wikipedia says: The Toyota KR engine family is a straight-3 piston engine series, designed by Daihatsu, which is a subsidiary of Toyota. The 1KR series uses aluminium engine blocks and chain driven DOHC cylinder heads. It also uses multi-point fuel injection, and has 4 valves per cylinder with VVT-i.The engine is also exceptionally light with a 69KG weight with all ancillaries. This is due to the nature of the applications and weight of city cars.
Which is about the same as me (before christmas that is... )
Loving this, having had tow Fiat 500's and had the engines out a few times, and now having a Citroen C1 (Same as Aygo) I can totally see the point, the KR engine is a lovely little unit and makes decent power, it has three times the power of the 126 unit but itsnt peaky, noisy or in a high state of tune but is still pretty small, looks like it fits very nicely in there, it wont be a pain in the like the 500 unit.
How are you going to do the cooling, what suspension are you using and are you uprating the brakes ?
Very very cool, car looks the business already, with this engine you're onto a winner. Theres an article in PPC this month on turbocharging these units, very interesting stuff, and the Fiat is so much better looking than the Aygo
I am struggling right now with the drive shafts. I have cv-joints to connect to the Fiat Hubs and I have the Toyota axles. I have been told that because of the metal alloy ( the 'metal mixture') it is not save to weld the Toyota axle.... There must be someone with good invaluable advice. Are there axles of older cars that can be welded which have the same diameter (21 mm) and number of splines (19) to fit the toyota cv joint....
You can also see if perhaps the 107/aygo/C1 have different drive shafts. I know they are supposed to be the same, but I seem to recall that toyota wasn't pleased with the french design and changed a few things. Sounds reasonable
Otherwise having driveshafts made is the easiest but also the most expensive solution, and I have no idea where to get this done in the Netherlands.
Good luck and really looking forward to the end result!
