or, fiddle with the aygo, have a car that very few have! and something that will eat standard cars alive :)

i wanted a 1.6 turbo lump in my ka, that wouldve EATEN a 2ltr turbo subaru & suchlike easily... and what would hurt their pride more than anything in the world? being overtaken by a ford ka :)

i wouldnt personally touch a K&N :)

But, good luck selling it ;)

Supercharge and standard Aygo and you'll blow the gearbox apart! The brakes wont be up to it, and how much worse would the already appaulling understeer be with that much power? The Aygo is fun to drive that doesn't mean it handles well enough to become a hot hatch without extensive suspension and brake upgrades.

My advise: if you want performance buy a car that is designed to go fast rather than fiddle with a cheap little run around like this and mess everything up including your bank balance!

thats all rubish as the standard gbox held well when i had the turbo on.

and the handling and braking are also very good and can even handle the 1.3 ltr tubo engine putting out 150 - 160bhp ! it can outhandle any car except 4wheel drive!

very bold statement! there neat little handling cars, but my ae86 leaves it for dead in the handling stake, and i could thing of atleast to other cars i've owned that put it to shame.

In standard form yes they are nothing special in handling But if you want to think that :thumbsup: all i have done on mine i lowered the original springs on it and it can prove you wrong! mine is newtral steering no understeer and no oversteer where the ae86 is oversteer all the way :rolleyes: thats why they are used for drifting i guess :thumbsup: then it depends also on the sriver mate :yes:

I'm sorry but the Aygo does not have chronic understeer as aygo vvti has said. It does have body roll and it does have indirect and fairly low geared steering (the thing which makes it least like a hot hatch) but it doesn't have bad understeer even with the standard tyres on it. If yours does then you need to get it checked out.

There's not really enough power or weight up front to make it chronically understeer if you think about it. The handling is not hot hatch though, but grip cannot be faulted.

Maybe it is because I am 15 stone though and sitting behind the front axle makes the car pivot around me though :yes:

I think bonzai Jo's supercharged did 20 000 miles with no issues with the gearbox or clutch, he didn't seem to find understeer either. Maybe he will read this and comment ?

The thing that most needs fixing with tbe Aygo is to increase the steering directness and steering ratio to allow the car to be driven more with the wrists.

well on the **** tarmac we have in malta and turbo fitted it understeer easily on high speed bends and with the 195 tyres it seem to do it more until i lowered the springs (my friends one with 195 tyres on standard springs makes you **** yourself around corners as it is all over the place but remember we have **** slippery roads) so if we can go fast on these i can immagine immagine on good roads it should be better

dont get me wrong, im not knocking the aygo,s handling, im very impressed with mine concidering its standard, but to say it will out handle most cars on the road apart from 4 wheels drives, i think is going abit over board, we all love our aygo's but sometimes i feel car forums do go a bit far talking about there car.

ps, the ae86 was first used for drifting because they came with a good lsd as standard were cheap in japan to buy and more importantly buy body parts for, they are actually one of the hardest cars to drift being low on power and shorter wheel base then most driftmobiles. They also were quite successfull in track racing and are still used by lots of people, people just assume there tail happy cause there used for drifting but there actually extremly well balanced high grip cars.

i know the ae86 is a very good car asw it eating skylines and integras on the track but if u were here in malta you wouldnt think so cos it would oversteer all the time (even a mk1 escort with a 13 engine would oversteer if you go fast around a corner here ! as with my vauxhall engined daewoo i use to overtake s2000 on twisty roads then when u see vids of them racing in japan they go around corners like on rails (i dont know if its only the surface or the cars are well modified too) we dont have any ae86 here or i would have had a go at it to see what its capable of ,when i put my aygo for the sprint challenge appart from other cars i also managed to beat an audi tt 4 wheel drive which take part in the championship (where i only take part in one race) and he was trying so hard that he almost lost it on one corner and almost crashed. My aygo handles like a gocart it must be because of the springs as i lowered them.

It does annoy me that there are so many people here making assumptions about the strength of standard parts or the viability of certain aftermarket components when they clearly have had no personal experience of testing them.

Please listen to people like Aygo VVTi and myself because we have actually modified our Aygos more than most and are therefore in a position to comment.

My supercharged Aygo (now in the hands of its new owner - check the forthcoming January issue for the giveaway feature) had 20k trouble-free miles under its belt and I would highly recommend the supercharger conversion. I have never had as much fun in a car as that little Aygo.

As for the Aygo's handling, with simply a set of lowering springs and 6.5x15" wheels with 195/45 tyres, it is truly superb - kart-like, if that's not too much of a cliche. Yes, just like any other front-wheel drive car, there is a degree of understeer when you really push on, but it is never a problem. Lift off mid-corner and you also get a wicked little twitch of oversteer to help tuck you in tighter. It is also true that a well-driven Aygo - even naturally aspirated - will keep up with more powerful machinery. For instance, at Japfest earlier this year I tracked the Aygo around Castle Combe. This is a very fast circuit not ideally suited to the Aygo (especially two-up as I was) but even so I overtook plenty of other Jap cars and kept up with a Pulsar GTi-R all the way around. He wasn't best pleased.

well said joe you did the aygo proud with your driving but remember that there are people that even if you give them a car that handle well they still manage to throw it out on the track and you have to be a good driver to bring out the potential of any car !

Guys, the point remains: supercharger is expensive and changing the engine is extreme (not to mention time consuming). Both of them, in my country at least are illegal. Ilegal because the car has to pass several tests and those are expensive and not really at least 50% chance the car will pass them.

Here's what I think: aygo is about 10K euros, add a supercharger conversion (ONLY) and the price is like 50% more. This is without anything else! No rims, no tires, no springs.

For 16K euros I can get a colt CZT 150 hp, 0-100 in 8 seconds that has everything it needs, not to mention the warranty and A LOT of optionals (like rain sensors and other stuff I don't need, but hey).

Talk about a second hand car? How about a honda S2000. They are about 16K euros. 0-100 in 6.2 seconds.

I am just saying that there are better things to do with the money (in my case anyway) then spending it on a city car. Sure, I want some more HP, but I will not go to extremes doing it.

If the gearbox in the Aygo is the same as used in the Yaris with the same motor, then the supercharger shouldn't break it. It's related to the old 1.3L turbo starlet box. The clutch pressure plate would probably need an increase in tension.

Personally I wouldn't stuff around with forced induction & associated troubles (intercooling, leaks, computer, space, heat, reliability, injectors etc).

I'd be more a fan of fitting a 189hp 2ZZ-GE, which in my country, would be a lot cheaper than the prices mentioned previously for the supercharger.

In my country adding a supercharger or changing the engine would both require an inspection, compliance, paperwork & fee.

well the motor is not thesame of the yaris as the yaris use to come with 4 cylinder and the aygo has 3 but the clutch and pressure plate from the 4 cylinder yaris fit and they are a bit bigger than the aygo one as the aygo one is really small.

Thats why i fit in the 4 ef-te engine as it would be cheaper than supercharging it and has more power ( at the moment mine has 150 - 160 bhp and all it had is a fmic and a boost increase to 10psi and its crazy )and in my country doesnt need an inspection you just inform them and pass the paperwork to the licensing office

Actually I find the supercharger conversion quite appealing. For one it is a turn key procedure, you simply hand over the car and the money and it comes back with 80% more power. Easy. It does not add too much weight and keeps the character of the little 3 pot engine too.

You could upgrade to a Honda S2000 or other car for similar money which has it merits ( better car, better image!) but then again you are looking at bigger bills, more money for road tax in the UK and not having a Q car.

i agree. it's all very well people saying you could sell x and buy y however if you are into modding you will mod y just as much as x !

on the face of it 4k for a conversion isn't that much when you consider the cost of conversions of other cars.

some people spend 20k on a corsa and do nothing to the engine. now that is silly....

The S2000 conversion gets it from 240 hp to 450 hp and costs 8K. The ideea is that if you are into modding, best get a cat that can be super modded.

ok so on that basis it's producing 225 hp per litre. obviously none of the running gear will need upgrading (I hate to think of the additional costs as S2000 parts are not exactly cheap).

I can't understand why anyone would come onto the aygo section and start knocking people for tuning smaller cars. I see the car as a modern day mini. You wouldn't go on to an original mini forum and start saying that there it was a waste of time tuning their car? and yet around a race track an original mini with 150hp or so can keep on the toes and even beat rwd and 4wd machines with 2-3 times the power.

tuning cars In my opinion is not about how big or powerful your car is, it is about creating something that involves the driver, puts a smile on their face and if it happens to be quite quick point to point as well then that's a real bonus.

there's really no point trying to belittle small light cars as on a race circuit it's proven time and time again they are still a force to be reckoned with amongst all the overweight barges.

1: the s2000 supercharger: this is the same company that makes the aygo supercharger... get my point? The hp increase is HUGE.

2: I am not knocking people for tuning smaller cars. Hell, I am tuning it myself. I am just saying that if you want to tune for real performance, a bigger engine is needed (as shown by aygo vvti) and the modifications will tend to be a bit extreme.

They aygos are a blast to drive, but an aygo + the req modifications will cost as much as a colt czt (150hp, designed for it) and will never beat it. That's a fact. And let's say the modded aygo will beat it. At what expense? A lot of Time, Money, Reliability problems, Safety issues. Not to mention the papers that it has to have to be street legal (at least in my country).
