Title: ko4-001 vs ko3s
Post by: porter_89 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.

I went in nicks ko4-001 mk4 from Rtec and it was really really good  :shocked: just the grand or so it is to make it happen that puts me off and the increased inability to corner.....
Title: Re: ko4-001 vs ko3s
Post by: tech1889 on 21 March 2011, 22:19
plus when you went in Nicks it had around 7500rpm rev limit and the car he will map for you wont have that lol as it will eventually go pop

Didn't nick saying he has been b0llocking his car at 9-10k revs day in day out and its fine?
Title: Re: ko4-001 vs ko3s
Post by: vwfiend on 21 March 2011, 22:22
Yeah, that rev limit was epic! Just carried on pulling and pulling!!!
Title: Re: ko4-001 vs ko3s
Post by: tech1889 on 21 March 2011, 22:22
It was fine but it wouldnt last for long and Nick has said that he just wanted to see what he could get out of an engine...

9-10!!! Does he now have a Honda???  :laugh:

Yeah, I am surprised how long its actually been going, I know the 1.8T's where tested in the design stage at non stop 10k runs or something close. If its track only I would unleash the rev limit just for the bends saving an additional gear change.

I recon my ko3 is on the way out. Its screeching/screaming at me when boosting lots 8psi + Weird thing is the turbo was only replaced last year.  :angry:

I'm Having the same thoughts and the ko4 001 is looking well tempting  :evil: I wanna try to get to about 260ish bhp running 190 at the moment.
Title: Re: ko4-001 vs ko3s
Post by: tech1889 on 21 March 2011, 22:34
personally i would recommend hybrid over k04 all day long.. if a proper company hybrid you can get 260bhp all day long.. plus you dont need to change anything on the car other than the usual intercooler etc etc
Title: Re: ko4-001 vs ko3s
Post by: porter_89 on 21 March 2011, 22:34
yea thats all i want out of my golf mate i think thats plenty and as its a direct bolt on its a more bonus
Title: Re: ko4-001 vs ko3s
Post by: tech1889 on 21 March 2011, 22:36
just dont use a sh!t company because they cheaper.. pay proper money and get a proper turbo.. some companies form people ive spoke to who have run hybrids have been using turbo casing off jap crap turbos fom ebay  :sick:

buy right buy once mate

Golf inability to corner? :grin: :grin: :grin:

Just go into the bend properly and control that throttle. Plus theres the famous saying:

Understeer is when you hit the wall with the front of the car, oversteer is when you hit the wall with the rear of the car.
Horsepower is how fast you hit the wall, torque is how far you take the wall with you.

Also tech I heard you are having trouble driving your tractor by overloading it  :grin: :tongue:

It goes round corners mate but not anywhere near as well as say a teg. For instance, a corner that I can hit at 80 max in the golf, my mates teg will do at 90 with ease............. And on the straight there is next to no difference between his 4 grand for the lot outta the box and my 3K of mods on top of purchase price

Dont mean to hijack the thread guys but if I wanted to go k04-001 what would I need? I have a 1.8t AGU so im guessing that i have a k03? i'm only after 250-300bhp aint really got the money for a big turbo yet.
Title: Re: ko4-001 vs ko3s
Post by: golf-sib on 22 March 2011, 08:08
K04-001 bolts straight on, you need bigger cc injectors to cope with the fueling and a remap. I also believe you can use AGU injectors with a 4bar pump and FBR, but this needs to be confirmed.

If your referring to an Intera DC2 then its not really fair,The golf is a comfortable cruiser with "ok" handling a good rise..

The teg is a 1100KG odd car with hardly any sound proofing a super peeky engine and is more race car than anything( i do indeed love them and intend to own one day :D ) Oh add its generally regarded as the best FWD handling car in the world by many people  :wink: so comparing to the humble allready which is the golf mk4 (regardless of how many mods) it won't handle as good
