Is stage 1 worth it?
- Thread starter Joe B
- Start date
An Update to this thread, as to whether stage 1 is worth it.
Car is now 3yo and I prob keep it for another 3 years.
I have just had mine done at a local shop that uses alienware and Kessi, then adjusts the map to the car and all checked out on a rolling road , and road test.
I specifically requested to map it for 95RON as 99 is ridiculousy priced IMO (and I dont see the point in anything over 240 for this engine.. to much wheelspinning for a 2WD), and the fuel ecomony in D mode is excellent usually.
What I wanted is the performace improved when in S mode, and on the DSG.
They adjusted everything including torque limiters for the DSG etc.
Results.... D mode.... much the same, but more torque when turbo kicks in, which is just what I wanted.
S mode..... now brutal accelleration compared to before and DSG just ticks changes so smoothly.
Before it was so so... and seemed to run out of puff at higher revs.
According to powerline on the Dynamometer, power peaks at nearly 240 @5000rpm.( Not bad for 95RON eh!)
So... is it worth it?

It appears, that is wrong.
The link below confirms SuperV8's technical information about the compression ratio being 11.6, but engine code DKZA does run a IHI IS20.
However you are correct in suggesting it is not simply a "detuned GTi", a lot of similarities but not totally, just as the GTI and the R/Cupra/S3 Engine runs a different cam which allows for exhaust scavenging (I forget for which I think it is the IS38 Engines that use it).
Even engine code CZPB uses IHI IS20, which is the other 2.0TSI with 190ps and the AVS system.

No, DKZA turbo part number in the Leon is 06K145654M which is a Continental not an IHI made turbo. See image below of this OEM part:
Haven't checked other models with this engine - or the CZPB.
Not that it matters who made the turbo! but just to confirm again - it is not a turbo from the GTI.
HahaDidnt even know Continental made turbos haha

I stand corrected sorry!
God knows where they got that information from then, maybe the US market only uses the IHI IS20 on their DKZA engines, who knows!
Please don't take this as an "I told you so" it is purely for information. I bought a 2019 Seat Leon Xcellence Lux ST over last weekend, as the S3 was getting to be too expensive in the sense that I could afford it providing I was okay with not having much money to do much else.Haha

So I had a look under the bonnet for my routine weekly self inspections such as coolant and oil level. I did remember this conversation and I figured whilst I was there I'd do some real world investigation rather than spewing specs from websites. For the sake of information being available on this thread, I DO have a IS20 with my 2.0TSI 190ps DKZA Engine, which probably confuses the already confusing VW line up even more!
No, only love here
Checking the parts catalogue again and I can see a year break change - for 2019
| DKZA | ||||
| >2019 | 06K 145 654 L | £ 1,116.00 | 06K 145 654 Q | £ 1,751.00 |
| 2019> | 06K 145 654 M | £ 1,209.00 | 06K 145 654 Q | £ 1,751.00 |
The M and Q are both Conti - but checking 06K145654L it is marked IS20! So seems early DKZA had IS20 and later they superseded to Conti.
06K 145 654 L
But I can also see IS16? Image is the same turbo.
I'm glad you took it that way! Definitely wouldn't want to have upset you in any way!No, only love here

Well the plot thickens and the VAG catalogue of vehicles and parts only gets more confusing!
Would you mind at all if at all possible sharing the parts catalogue? It may come in handy in the future!
I'm not very knowledgeable about the continental turbos if I am honest, do you know if there is a difference between the two and which one on paper is better? I do like the sound of having a IS20 coming from a IS38 because it is more of what I am familiar with, and I can be a creature of habit in that regard!
Sorry can't share catalogue - it's not a free catalogue.I'm glad you took it that way! Definitely wouldn't want to have upset you in any way!

This one is - not quite so upto date but not bad:
CATCAR.INFO - On-line auto parts catalogs
On-line auto parts catalogs (Audi,BMW,Chrysler,Ford,Hyundai,Isuzu,Kia,Mercedes,Seat,Skoda,Mazda,Mitsubishi,Nissan,Subaru,Suzuki,Toyota,Volkswagen)

No idea on the technical differences - The fact the Conti superseded the IHI to me suggests they are equivalent.
Revo remap on 190tsi goes to 242-266 where as on the 220 GTI it goes to 313 - 333! Confirming the 190 is not just a detuned GTI engine, there are some fundamental mechanical differences - still a great engine, just optimised for efficiency - so peak power/air flow is lower.
