Stage 2+ K03 best mods/ expected figures
a8rnx:
Some serious figures in here! Very surprised but excited lol!
Sorry to hijack the thread but thought I would post as I am looking to do the same thing. I had my Mk5 GTI mapped by Niki in the summer and made 255bhp 316ft/lbs with just the 2 cats removed from the exhaust. Now I want more power but I am so torn between going stage2+ on the k03 or stage2+ on the k04!
Would be great to hear your views and opinions guys!
Thanks in advance :happy2:

^^^^ Given a choice, there's only one......... K04......next!!
GrayMK5GTI:
K04 is just better :laugh:
If you want serious power then K04 is the way to go, such a great turbo for response & power band :happy2:
As I've said in other posts too, it's better for traction as the power delivery is typically smoother and further up the rev range whereas K03 spools almost like a diesel turbo with huge wad of torque low down making it easy for the wheels to break traction

I can't wait to get down to R Tech on Wednesday. I've no idea what figures to expect, but I'm looking for more midrange torque. I've had a custom map on for 70,000 miles now and it's always had oodles of top end power and really takes off at 4,000rpm, but it'd be great to see that power come in at 3,000rpm or lower if possible.
I'm running: ITG Maxogen G60, Loba HPFP, Forge Twintercooler, Longlife custom TBE w/200 cell sports cat. R8 coilpacks.
I must say, even though the car has been polybushed front and rear, so was stiff anyway, the recent introduction of 034Motorsport Density Line engine/ transmission mounts and Vibratechnics subframe mount/dogbone bush has made such a difference to the power delivery. There is literally no movement, the car handles on rails. In a way the power delivery feels a little less exuberant, because it's smoother, it's not, but it feels like it. I also noticed being able to get on the power quicker after fitting the uprated Neuspeed crankshaft pulley.
