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

Thank you too. You turbo running out of interest? Don't wanna go to stage 2 for the turbo to go!

get your car to r-tech they will advise you whats best for the power you need :smiley:

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! :smiley:

Ahh coolcool, sounds like a beast but one that isn't maxxing out it's components. Hmmm. So you haven't upgraded the fuel pump...have you got new injectors or are they stock too? Sorry i'm being nosey little person here.
It is however tempting to stay with my set up, in a year or so get a new lower mileage gti and do the full whack. Nahh, stage 2 it is!

Standard fuel pump, standard injectors. :smug:
Here's a list of the performance mods,
Evolution custom map
Longlife T-304 80mm stainless exhaust w/ sports cat (Don't ask why it's 80mm and not 75mm like everyone else has)
Raid HP T-304 stainless cold air induction system
Forge twin-intercooler
Forge diverter valve
EBC Front 312mm d&g discs.
EBC Rear 285mm d&g discs.
EBC Front/Rear 'yellowstuff' pads
Dot 5.1 Brake fluid
Walkline Anti-Lift Kit
APR torque arm
Poly-Pro suspension bushes
Goodridge stainless brake hoses
:smiley:
It's fast enough for me, you can trawl my thread for figures if you wish (Fecking nerdy I know) - http://www.golfgtiforum.co.uk/index.php?topic=225815.msg2083311#msg2083311

I have already had a little look! I'm pretty much there (about 75%) albeit with different part manufacturers. Thank you!

have a look at this guys mk5 runnin nice figures :wink:

Sounds like a nice build dude. So what mods are you running if you don't mind me asking? Have you had it on a rolling road?

Maxxeh's build is an epic one for sure, but to be running 400bhp+, of which I'm not overly sure how much is usable you need to add - HPFP, WMI, KO4, LSD, Uprated Injectors, Uprated Valves, Uprated Clutch and more. It's a great project if you've got a spare £8,000+ (I haven't :cry:)
Hurdy's ED30 was running at 370bhp before he added a 100bhp Nitrous shot. I love to read about all these builds and in a way it has increased my own propensity to want to continue upgrading and upgrading and upgrading, but where does it stop? For me spending £3k on the initial modifications along with the extra running costs that comes with such a build is enough.
But if you've got money to burn, then get it on it, like a car bonnet!

Epic!

Completely missed this. Rolling road = both consistent at the 240 bhp mark.

Modifying a car is a very personal thing. The more you do to it, the more you become attached to it.
I got this with my ED30 and even though the fwd set up restricted use of most of the power, it was still great fun to drive.
The K03 is a great turbo and has decent scope for performance gains and suffers almost zero lag. For a fwd it is a superb match. The K04 is also a superb piece of kit. It just adds a tad more lag, but big power gains. Ultimately for a fwd car it becomes the owners personal preference and depth of pocket that determines how far the power curve goes!
Big turbo conversions are awesome, but yet you have to console yourself that the power and moves further up the rev range with each increase in the turbo size and lag also becomes more prevalent. Then you have to consider the amount of throttle you can deploy in any given stretch of road otherwise the car becomes more of a missile than a car if you get it wrong and not a guided missile either!! :shocked:
For 90% of people a well modified K03 GTI is more than enough to make them happy, 8% would be happy with a modded K04 and then there's the 2%, who are certifiable! Lol :laugh:

Nicely put and ties in with my ideology too. I think ultimately if your 'project' is also your daily drive, then it comes down to money and how much you've got at your disposal. As Hurdy correctly identifies, the KO3 suffers from pretty much zero lag. So if you want a 160mph+, 0-60mph in 5.0-5.3s Gti with only a KO3 and you don't want to spend much more than £3k, then it's ideal.
Also for me personally if I used my car as more of a track car, then I would probably continue to mod and mod and mod, till the cows came home or I went bankrupt :wink:
Hurdy and Maxxeh definitely fall into the 2% category. Although at least now Hurdy has an 'awd' car that can cope with 450bhp+ without turning into an unguided missile :laugh: And with the 'R' you really up the steaks in the modding game. With 0-60 times being churned out sub 4s and 1/4 mile stretches done in 12s, you really are in another league.
