Fiat Uno Turbo Mk1 (1.3l) and Mk2 (1.4l) requires no mods in the bay. They are easy to tune if you want serious power. Those engines are very close to the 1.5l. -Flywheel, clutch, starter and gearbox from X1/9 fit directly.X1/9 experts: What is the most powerful engine that requires the least internal modifications of the X1/9 1.3L engine bay?

With an alternative intake and injection system the B series Honda engines could likely be installed with only changes to the mounts and not effect the rest of the car.
If the question asked by @JorgeFiat is what's the best "bang for the buck" swap, then I'd say it depends on what is available to you there in Spain. I agree with @Bjorn Nilson the Fiat Uno Turbo is likely the easiest route, but we don't have that option here in America (no idea if you do in Spain). Therefore here the best option (in my opinion) is what @kmead said with a "B" series Honda. But I also don't know what their availability is there either. Again, I'm saying these are the most improvement for the money spent - not the outright most powerful or "best" conversions in other terms. Other factors for your particular goals will come into play as well. Regardless, I'm of the belief you are best off buying a complete running donor car with whatever drivetrain you prefer. That way you know the actual condition of everything (with no costly surprises), you will get all of the little bits and pieces you end up needing in the process, and it is usually the most economical way to get a drivetrain (i.e. in a wrecked car).Fiat Uno Turbo Mk1 (1.3l) and Mk2 (1.4l) requires no mods in the bay.
Steve,
Your are probably right, as usual, but I was thinking a 28HP Diesel Cat engine would pull hard.

It's about time we got something practical. There have been several similar designs for ages in other parts of the world. I wonder if the GM unit is a original design of one of the others that's been around. Isn't GM in bed with some Chinese car makers? Maybe it is one of their engines. Ford also has a really cool one in some European Fords (quite different from US Ford). I rented a Fiesta for a couple weeks in Cypress with that engine and it truly amazed me. I'm sure they will soon offer it as an option here in their smaller US cars. And isn't the Smart a turbo 3-cyl? Although it's French made. But yes, anything along those lines would make a good swap in the X. Think about it, in stock form it is at least equal performance to a fully built X1/9 race engine, yet much lighter, more reliable, and offers better drivability. And I'm sure there will be performance upgrades offered for them....bump up the boost, bigger intercooler, reflash the ECU, and presto you have 225 HP and 275 lb torque. The aftermarket industry is not only very diverse, but also very competitive. So they jump at any opportunity to be the first to offer something new.This may not be a "new" engine for GM but it's being brought into the mainstream production this year in several GM lines.
It's a 1.3L turbo triple, 154hp, 175 torque.
All aluminum, 4 valve, probably variable cams, direct injected.
Obviously like all newer engines computer controls are going to be complicated but there are ways around that.
Haven't seen one yet, don't know the dimensions or weight but it still looks interesting for future swaps.
Jeff, After the 2008 election GM was nationalized. The new owners (the government and the Union) started producing Buicks in China for sale here and in China. Not sure what is happening now or if that's what you are asking.Isn't GM in bed with some Chinese car makers?
I think an aftermarket ECU would help a lot. I assume the VW engine has Bosch standard sensors and triggers, and if not they are easy to replace. I noticed some Abarth 595 swaps where people kept the stock ECU that obviously complicated things. I don't understand why they didn't remove the stock harness and ECU that seems to contain a lot of none engine related rubbish. -Having an aftermarket ECU made for engine (and maybe gearbox) management only must be a better route.I have always thought the all aluminum EA211 VW engines used in the Polo (the twin cam in particular) would be a nice compromise of German stolidity and reasonable weight. They would be available in Spain
It is a modern engine so may be difficult to acquire engine management software to take advantage of it.
I agree. Even for electronic trans there are programmable standalone aftermarket modules. I often wonder why they go to such extensive effort to try and convert the stock modules to work. Seems they spend at least as much time, money, and more frustration that way. And even then they seem limited on what they can do with the tune - mostly relying on a outside source to remotely give them something generic. But I suppose in some modern applications it might be more necessary than others, depending on the complexity of the stock systems.I think an aftermarket ECU would help a lot.
Maybe not for this thread, but anyway...I agree. Even for electronic trans there are programmable standalone aftermarket modules.
I think the stock drivetrain could handle that level of power if it isn't abused. Depends on what you intend to do though. Big smokey burnouts, drag race starts, drifts, donuts, etc, won't work with this drivetrain regardless of the level of power.With a more powerful engine (lets say 140-150 HP) will I need to change the drivetrain/clutch too?
GM was never nationalized. They had Treasury loans (paid back) and Government stock buys that the government sold back in 2013.Jeff, After the 2008 election GM was nationalized.
