ko4-001 vs ko3s
« on: 21 March 2011, 17:37 »
hey guys i did a search and found some info i was just wondering what turbo everyone prefers
im running a ko3s atm but want more power in the long run
i dont want the hastle of putting a proper ko4 onto my car and seen on nick at r tech he put a direct upgrade onto his the ko4-001 i was wondering what sort of power you can get out of these i am very tempted with the turbo just for that little bit more power but i dont really inderstand it thats all

cheers

If your truly mental then you can hybrid a ko3s and get <280 bhp and 300 ftlbs but you have to uprate injectors, maf and fuel pump as well as fitting mapping and getting the turbo rebuilt but youll never see anywhere close to what youve spent on top of the car value and the golf handles badly for me at 236 bhp........ Id stick with the Ko3s pal. 'but thats just me' 'thats just me'  :grin:

i had a k04-001,    The 3rd gear pull with this turbo is mad :evil:


I would not upgrade to a k04-001 if you have a k03s.     Only reason i did cuz i had a k03


Get a GT28rs :D

If you got a k03s to begin with, i'd stick to it, otherwise go straight for a k04.

I will be eventually going k04 due to costs vs a k03s are not much more. It all depends what you are after as well, 230 or 260bhp, both turbo's don't suffer lag and the size is not much different, k04 is slightly bigger and has a 51mm inlet, k03 series has a 50mm inlet. Biggest downside on the k04-02x series is the exhuast manifold, off course if you go k04-001 route this is not an issue as k03 manifolds are less restrictive.

But I am not sure on the reliability or boost levels of a k04-001.

You could go crazy and get a stroker kit and have a 2.0L 20v engine with a hybrid or bigger turbo like gt28xx... But its all down to what you want and how deep your pockets are.
