My i20N

Here is some more tyre info….
The conclusion here is in line with that of Auto Express, all our favourites are considered excellent but the ‘winner’ is the Pirelli P Zero PZ5. Now the key point is that he reviews the new (8 months ago) PZ5 and lots of places are still selling the previous PZ4… Obviously the i20N comes with a variant of the P Zero - but it won’t be the PZ5 as that hadn’t been released. To further muddy the waters, I do think the standard tyres are fantastic - but only in warm conditions. I picked my car up in high summer and the grip and turn in feel were remarkable. But as soon as the temperature dropped into the low teens the tyre skip on full lock was horrendous and grip plummeted. Unfortunately that kind of poor weather accounts for about six months of the year here in the U.K. and makes this a very challenging tyre to run on a daily basis or even on a ‘hobby’ car. How the PZ5 compares to the stock tyre I don’t know…. (I suspect the stock tyre is simply a 215 width version of the earlier PZ4).

I just found that the updated turbo for the i20n comes in three versions. Data from the website are saying that the first stage turbo upgrade, does not need ecu modification while stage 2 and three need to be modified. ", good point - but I am interested in hearing the results when you manage to source a turbo
.
Required conversions
When converting to Stage turbochargers, customization of the software is recommended, and even required for Stage 2 and above. To achieve the maximum power, which the turbocharger provides, we recommend depending on the vehicle and engine a larger Downpipe, possibly also entire exhaust system, a larger intercooler and a modified intake. Recommended for most engines is also to strengthen the engine."In reality the only parameter you have to make sure its perfect for safety reasons, is the correct af/r, so as not to make the fuel too lean, and skyrocket the temps of the engine. So for stage 2 (280-290 hp) i strongly believe that the combo with the Dtuk box (which runs on the rich side) has many possibilities to work nicely.
Last but not least, they suggest a larger downpipe with an entire exhaust system, so as to lower the EGT temps, and not restrict the power figures.
My car has all those recommended mods, including the larger downpipe (3” diameter).
I have also read the same, or very similar, from turbo suppliers but I have to say I think a lot of what they state is rather speculative rather than based on actual first hand experience of adding a larger turbo to the i20N. What they say in that statement is very generic and applicable to any turbo upgrade situation.
As you say, the danger of increased forced air induction is that the fuel/air mix will be too lean without some sort of ECU intervention. If the DTUK box is able to achieve this then it may make adding a hybrid turbo much more accessible for many
. I look forward to your further findings .

Yesterday I was pulling into a parking space at exactly the same time as a lady was pulling into the opposite space - it was as if we were synchronised . Anyway, we got out of our cars and the very nice middle aged lady immediately set about telling me how nice my car was and even praised the ‘throaty’ sound it made! Obviously I was pleased, but also somewhat astonished - normally it’s teenage boys who like my car
