I got a ko3s and all the extras, it makes nice figures on the rolling road and goes very well. Much fun to had hammering so called fast cars in a glorified shopping trolley:D


Here's my latest RR print out, nice figures with out hammering the turbo.

The boxes below are, top row - bhp, torque, bottom row - AFR, boost.

i have a k04 on my ibiza and i love it. 275 is perfect for the ibiza, it embaracess alot of cars too. If you already have intercooler and cat back its not gonna cost the world. you can get all the parts reasonably cheap if you look hard enough. All in all i would say go k04 :funk: bit biased tho. If you need any questions answering you can pm me if you like?
Cheers, Jack

Thankyou, i'll bear that in mind. I'll do some research on whats needed for k04 and weigh it up i guess. As it stands, k03s is looking quite cheap.

Jim curley at Star Performance.

It shouldn't have that spike around 2800rpm but i've put a restrictor in front of the N75 which makes it better on the road but not as pretty on paper. Similar effect as changing the N75 for a race one but more effective.

Cheers, i've heard mixed things about Revo2. But as its only £50 i'll give it a go. I'll add Star to the list of 'plan b' mappers. Any more info on your restrictor, as again i've heard mixed views on different N75's but never changed mine.

It's the electronic boost controller, you can find it attached to your TIP with three ports (actuator, TIP and charge pipe)

If you check out the FAQ section Ant there's a post explaining all of the acronyms :)

haha proper bit of thread jacking ;) Yeh Ant a ko3hybrid is more powerful than a ko3s.

Turbo Powers are like this:

Ibiza Cupra KO3 Turbo 156bhp

Later Golf's,Audi TT's and Leon Cupra's kO3S 180bhp

Leon Cupra R's and TT 225's came with KO4 turbos

A hybrid, be it either a ko3 or ko3s is basically a KO4 trurbo but in the shell of a ko3/s

Hope this helps ;)

Dont forget there are different k04 turbos. The one that came on Audi TT 225, S3 and Leon Cupra R is a K04-023. There is also a K04-001 which wsa an early variant of a k03s and performs just like a k03s.

Indeed two variants of the KO4 the 210bhp one and the 225bhp on the later versions, turbos are the same i think, just a mild map making the difference in power

Yep, the 2.0T k04 is also completly different in size to the k04 as fitted to the 1.8T
