    K04 Upgrade questions

    I currently have a '97 1.8t sport A4. As it is the first phase of this engine, so i am told, it will only make 180bhp after chipping, an increase of 30bhp.

    What i considerd doing was changing to a K04 turbo setup.

    Can anyone tell me since my car is NON-Drive by wire. would this create any issues?

    Is the K04 a direct replacment job. or does it need different pipe work or engine management, injectors or anything else? I know that the car will need re-mapped if i was to run the K04.

    What kind of power should i see running a K04 and having the car mapped to it?

    I have also herd people speaking of a K03s turbos, would this be a direct replacement and what is the difference between it and a standard K03?

    Re: K04 Upgrade questions

    MRC will get 200bhp outa ur 97 car mate. Mines a 95 and its runnin like a dream.

    Few problems reported on the K04 front with an older car. However theres a thread in the a4 b5 section that seems to overcome these problems.

    Re: K04 Upgrade questions

    220 to 225BHP out of a 150BHP engine is not going to happen dude. The turbo can't do it, end of story.

    I had my engine remapped at AmD quite some time ago (I have the 180BHP facelift car with K03s turbo and Milltek cat-back and de-CAT) and although it was pleasing at the time and produced good results, (I don't mean to burst the bubble here so sorry if I do) their figures lately have been a little ambitious at the very least.

    There are others who will argue the same and others further who swear by them but all the hype is not to be believed. Just take a look at history and the trends of peoples engine remaps on here for a start... I'm not sure I've ever seen the earlier 150BHP engines make significant power over the 200BHP mark and few that reach the 200 mark actually. Some do get get close though...

    Just a few comments to show the other side of the equation there bro' and I'm sure they'll liven things up a little [img]/ubbthreads/images/graemlins/wink.gif[/img] Just my opinion obviously so don't shoot me! [img]/ubbthreads/images/graemlins/tongue.gif[/img]

    Yes the K04 is a direct drop-in replacement providing you get the correct variant - K04-15 for the A4. No different pipework needed. Engine Management will need to be remapped to cope with the extra flow that the bigger turbo produces. Your injectors MAY need to be replaced, it depends if your tuner thinks the car is underfueling when he maps it.

    I think 250BHP is possible with the K04...

    [/ QUOTE ]

    It simply flows a little more air allowing the cars' engine to produce a little more power with correct mapping and was fitted (as mentioned above) to the facelift model A4's and a few other cars (Seats??) if I remember correctly...

    Hope that helps.

    Re: K04 Upgrade questions

    Have a look at this thread for some background reading and info.

    If you want to buy new then speak to VAGParts - you can take a look at their website at www.vagparts.com

    Just tell them what you are doing and that you want the K04-15 and they will know what you mean.

    I don't think it will be cheap though, you may be better off sourcing one second hand... I think I remember Madkebab having one for sale recently, not sure if he sold it or not. PM him to find out.

    Cheers

    Re: K04 Upgrade questions

    Iv got a panel filter, and a forge DV.
    Not major power accesories!
    Just the chip and im about 195. OOoo and an S4 arch liner for he intercooler!!

    I agree with tim on this too. I just cant see much over 200bhp with a k03.

    An Exhaust makes very little power diff at this level, and the induction kit could lose you power thru heatsoak, cant see 225... think you'd loose a hell of a lot of torque thru that 2! Adn thats what makes you feel like ur goin sumwhere!

    Re: K04 Upgrade questions

    I have an induction kit at the moment. So you advise taking it off for standard unless it was inclosed ie BMC or cold air intake carbon thingy?

    Re: K04 Upgrade questions

    Personally, yes. But if you've got it and paid for it...
    Basically, its a noise thing more than anything.

    I'd like the noise, tho it can be a bit chav. But its a lotta money for no power.

    But the K04 we are talking about should be breathing more so may need a BMC to give the best gains.

    Re: K04 Upgrade questions

    Hi lads.

    I had my car rr'd today and made 166.5 BHP which is 16.5 bhp up on standard. With only an n75 J valve, uprated D/V and an induction kit with no heat shielding, which the guy said the induction kit is holding the car back as it is just sucking in hot air, and that running it like that can cause problems. So i am going to put it back to standard as he said it would benifit the car alot so maybe i might see a horse or 2 if i do.
    I checked the other cars that were running standard setup and they were making accurate power give or take a horse or two. So cant put it down to roller inaccuracy.

    Re: K04 Upgrade questions

    blue one?

    Don't buy a KO4. if you are willing to stretch for a turbo upgrade get one that will at least grow with your budget. I know three people who swapped KO3 and KO3S for KO4's and they are all now on Garrett or some other aftermarket.

    The KO4 will not cope with the abuse that a late 200's early 300's bhp remap will give it.

    There are exapmles out there of it acheiving that, but they have significant mods to back it up or they have had a number of units in there.

    Re: K04 Upgrade questions

    I'll believe that when I see it... [img]/ubbthreads/images/graemlins/tongue.gif[/img]

    As far as I know the K04 cannot flow anywhere enough air to produce that sort of power, regardless of the remap.

    But I could be proved wrong... [img]/ubbthreads/images/graemlins/crazy.gif[/img]

    I do agree with you on the Big Turbo upgrade though... faced with paying for the upgrade in the first place you may as well start with something you are going to get the benefit of. On a pounds Vs Power scale there is no point, in my opinion, spending the sort of money the upgrade will cost on something that will yield very little power gains for the money spent. You'll always wish you had gone for the Big Turbo in the first place...

    Re: K04 Upgrade questions

    If you go for a KO4 eliminator and run like say 300bhp. Will you do through drive shafts and things, or can you get uprated ones??

    I have never heard about people changing those things or anything about them breaking because of the bigger turbo.
