Ok, pretty simple question but i'm getting nowhere!
What turbo does a Mk5 Golf Gti have? KO3 or KO3S??

I have only heard about KO3 when reading about the GTI. Not sure what the S is for.

Likewise! I've been reading up looking to get the car mapped to stage 2 but been hearing problems with the KO3 turbo above 240/260 bhp, but then read that Mk5's might have KO3s turbos which can handle the additional bhp without much issue! Thank you anyway. Adds mystery to this project.

Has the K03. Not K03S

If u want more power go for a K04 from an edition 30

They've got a KO3 and they're f**king tiny!

Thank you! See see vagtech want £1900 for the install without parts - but then again I have all the necessary parts on the golf already...just need a new fuel pump. Hmmmmmm

Good shout! I have been looking at them for the past few weeks. Friend of mine had an excellent experience with them, but their website didn't say they could fit the parts I was thinking about/or mention it. I think i'm being a n00b. I'm gunna send them an email.
Cheers!

Mine's the standard KO3, with the waste gate rods closed up a bit and a custom map, along with a host of other mods. It's good enough for me to be honest. It's at the 300bhp mark as it is currently and whilst it may do with a slight improvement in mid range torque, without making a multitude of other mods it's not really possible. Plus which the turbo isn't under too much stress, it spikes at about 20.4psi, holds at 17.2psi to 4,500rpm and then drops off to about 14.1psi to the redline.
I could go out and buy a KO4, HPFP, WMI, Quaife Diff etc and spend another £3,000-£4,000 and end up with a 450bhp Golf. But to be honest I'd rather sell up, buy an M3 or a Golf R and get it remapped and stick a shiny zorst on it!
