An idea of engine swap in Aygo X

[hologramcard]

In Asia there is Toyota Raize that uses 1.0 but with turbo, what do you think about installing that turbo into the AygoX if it is the same 1.0 engine?

[haelewyn]

Wouldn't there be other parts of the engine that are adapted too ?
In that case, wouldn't it be better to switch the complete engine and scoop one in with a turbo ?

The brakes would be, maybe more potent.

This engine was also sold with turbo on Daihatsu cars in Europe, by the way.

[flash22]

the modern equivalent to the old Daihatsu EF-DET would be a 1KR-VET

1kr-fe will need major work to turbo it properly, and 1.33 will give you more gains for less hassle NA

It says Toyota Raize uses a 1.0 Turbo 1KR-VET model

so i would ask the Toyota mechanic here if he can install the turbo on the AygoX CVT gearbox, but in Toyota, they say I will lose a 10-year warranty not just on the engine but the whole car 😞

the I don't know what to do, car is good but the engine is underpowered, maybe I will look for competition (short car 3,7 with raised ride height)

I struggled with the same question in my head.

Being objective, it is cheaper to trade in the aygo after 2 years if you can't get used to it.. buy an other and more powerful car.

They don't lose much value so you won't fall too deep if you do.

Sorry to say so but all other options are half work, ruining the car or just throwing more money against it than what it's worth.

Shorter explanation  : there is no other reasonable solution for the problem.

Cvt : who says this can handle 40 percent more power during its entire lifetime. Bad idea imho.

I don't own the car, i just had a trial. The car has advantages and in the future, I might buy it. 

Toyota Raize also has CVT, which could be the same or close to the one in AygoX, I am guessing it could tolerate increased power.  I don't know, I think the car should be sold in way higher numbers if it has at least 85-90hp, I don't know what the CEOs at Toyota are thinking, for it does not make sense to have just one engine for 15 seconds to 100km/h performance and say that is it. 

Just like in Citroen, almost every car has a bad manual gearbox, and each journalist says is bad, and they don't fix it.

If every other car maker knows how to make it it means it is not about cost saving because people don't buy the car then and you lose much more.

 

Many things overall are irrational, so it seems Toyota has its own part in that.

[Cyker]

They won't because they already make a small car that has or exceeds those horsepower figures - The Yaris - So to them it would be irrational to do that, as much fun as it would be to have a Yaris engine in an Aygo.  

Remember, the Aygo's brief is (Well, was. I have no idea with the AygoX. Is there such thing as a premium budget car?! ) to be a budget small car, performance is not a thing it's designed for. Blitz did sell turbo and supercharger kits for the older models but they were difficult to get outside of Japan, more so since they apparently had a falling out with Fensport, who were (one of?) their main importer.

Anyway, for what it is, the Aygo's engine is fine IMHO - I have a feeling you are used to much more powerful cars and are averse to revving out the engine out of mechanical sympathy, but it's japanese so all the power is at the top end so you'd just have to get used to it.

Or buy a Yaris.  

[haelewyn]

Or a mg3+ for 18000 pounds with a 3 gear box and 192 hp.

I think i have found a solution that will keep me happy 😃

 

remap brings to 80hp, and that would be enough to tolerate, along with sport filters it should be acceptable and is not that expensive

 

[flash22]

Modifications will invalidate any warranty

How is it being remapped? To my knowledge nobody has cracked the Toyota ECUs so usually you'd need a third party one e.g. AEM, or use a piggy-back box which can be of vastly varying quality (A lot of them, esp. the cheap ones, are just a bunch of resistors badly soldered together in a fancy plastic box!)

Just be careful!

[flash22]

A filter, Exhaust and remap/ecu will set you back £1000 - Sub £300 tuning boxes are utter junk - and will cause long term issues

the Aygo X is a Toyota from the ground up, Toyotas are very difficult to remap it's a very specialized job

this is only map changing (software) with no physical box

They do not have the authority to hack the engine map unless something is wrong then they should, but with the normal map they don't know what has changed

I am not sure how, but i just saw that one company offers tuning and it has been on the market for cca 20 years. 

I think this engine is 20 years old and it went into the Peugeot and Citroen so maybe the ECU is different, I don't know

[flash22]

It uses the same engine 1KR-FE, but it's a far more advanced design it uses a very different ECU with modern encryption compared to the Mk2, I doubt many places have had hands-on tuning experience with the X as it's only been out 3 years

 

Many companies "offer" tuning products

[Stormchaser]

You,d be better off just Manual swap it so you can wring its neck under your control and not the cars control haha.

It is possible too (on the MK2 it is anyway) and quite cheap to do.

[flash22]

The CVT has no effect on the engine ecu, remember not everyone can or wants to drive a manual - i, for one, will not be going back to a manual as 90% of my driving is extra urban

[Cyker]

I think I would if I was going back to a petrol or diesel car, but it just doesn't make sense with hybrid and EV drivetrains.

i just called the tuning company, they only have remap for the older version 68hp tuning 😞

[flash22]

the mk1 and mk2 are tunable as per the city cup

One of our cars started life with a Ford 1600 x-flow producing about 80 bhp. Eventually it had the usual 80's mods carried out e.g. head mods, high lift cam, twin Webers, better exhaust and it then produced about 130 bhp. Used it like that for about 15 years but there was an issue, it was not terribly pleasant to drive and was pretty diabolical on fuel, would do about 20 mpg.

By about 2002 the engine was ready for a rebuild but instead I decided to update the car to a modern engine. Stuck with Ford, a 2 litre Focus Zetec and luckily for me all the parts needed to fit it were available from various suppliers. The engine was the cheap bit, £700 brand new in a yellow plastic crate and after selling the bits I did not need on e-bay it owed me about £500. The parts to fit it were not cheap at all (but I knew that before starting), at the end the bill was eye watering. 

What I ended up with is a car with about 175 bhp (no internal mods required, the new induction and exhaust release the power that Ford designed it to have) that your granny could drive to the shops and does about 36 mpg. 22 years on all the engine has required is the usual oil changes and a cam belt (another is needed this winter). Uses no oil and there are no leaks. There is one part common to both engines, the oil filter.

No regrets at all and I love the car but I would never do it to a car like an Aygo.

What you said bit translated in a kiss way : if you want to buy a 175 hp car... then buy one.

Don't buy a 72 hp car and try to make it it a 175hp one.

What on earth does the first line mean?

FYI had car almost 40 years and will never sell it.

Sounds the best (least worst) option to me
