ko3s/ko4

[bgasmatt]

guys am after a new turbo as stated a ko3s or a ko4 + parts req to fit k04

where is the best place to source these parts.
and what price would i be looking at to do the k04 and what parts are req cheers matt.

 

[pj1985]

Search. K04 is not a straight swap and it would prob be cheaper to get a hybrid k03 like the jbs04 than a fit a k04 unless you can fit it yourself.

 

[bgasmatt]

yeah no problems fitting myself m8 is the jbs 04 a direct replacement as in bolt to exsisting mani and 2.75" downpipe. and what price in it just for the turbo and what power would be expected from it.

Any help to you

 

[bgasmatt]

have already looked on there at there stupid prices would never pay that for a fitted turbo its a joke lol i would just wantto buy the the turbo and fit it myself cheers anyway.

 

[pj1985]

Well thats where to buy the jbs04 turbo from even if you fit it yourself. A k04 is not a straight swap. Could look at the eliminator kits but they are not that cheap either. All depends on what mods you already have.

few options really to be honest mate

you could get a k03 (2nd hand off ebay) for about £150 and have some hybrid treatment. If you want to do this, then give CR Turbos a call www.crturbos.co.uk. This is what a JBS04 is, nothing special, just a hybrid k03 and IMO some what over priced. So it would be cheaper to source the turbo your self and get a 3rd party to carry out the work

CR Turbos have just done the work on my Garrett GT2x and gave it some hybrid treatment. Fantastic service and I highly recommend them. This is also a direct bolt on to the standard manifold, although this turbo was not cheap

k04 has a different manifold and would require a lot of work with re-routing of other pipes etc and would be quite an expensive route versus the power you would get out of the turbo. Although if you managed to find a written off LCR or TT for example, and you can do it all your self then, again, this could be a viable route. typical K04's with a remap will make about 260-270bhp. hybrid versions make about 290bhp I believe

remember, its not just the turbo, but if you wanted to go down this route, you also have to think about uprated injectors, FPR, fitting, mapping etc, so there is quite a cost in terms of a "turbo package"

hope this helps

Like jamie said either a hybrid k03 or eliminator kit are the simplest to fit but are not the cheapest. Doing a k04 is harder to fit but the parts are cheaper to get.

Jamie-Wouldnt go counting your chickens jamie. Hopefully the work that cr turbos have done is good but you have not tried and tested it yet remember so recommending them might not be the best idea until you have fully tested their work.

very good point their PJ, putting all my eggs in one basket, but certianly in terms of customer service and expertise, they were very good. but as you say, proof is in the pudding

how much would a hybrid k03 cost then? say £150 for the turbo from ebay, then about £500 maximum for the hybrid treatment? which would be the equivalent of a JBS04, and still a lot cheaper

 

[pj1985]

Maybe. Depends on what you have done. Nobody apart from jbs know exactly what spec the jbs04 is so you cannot say take it here giv them £500 and you have the same as a jbs04 but it might be close.

well a hybrid is a hybrid, in terms of only so much work can be done to a turbo bringing about a total cost (all be it different levels of work)

when speaking with CR turbo's they asked how much I wanted to spend, and I was like well what can you do, chicken and egg type scenario in the end I quoted about £200 maximum, which bought about a number of pieces of work on the turbo, greatly improving it

but my point is I could not imagine the cost being more than £500, as the typical work they would do is:

360 thurst bearings
reprofiled housing (dependant on how thick the walls of the turbo are defines how much metal can effectively be skimmed)
larger turbine
larger turbine housing
largened exhaust outlet

the list goes on

but certianly that would make it into or part way into a hybrid k03.

Of course JBS wont say what they do, as its their product (trade secrets and all), but it cannot be anything magical is my point, hybrid is a hybrid at the end of the day, and any good turbo specialist can carry out the same aspects of work on a K03 for what JBS have done to theirs

150quid for a K03 LOL

i've seen em go for 30quid

 

[pj1985]

Thats true in part but the hybrid work done by one place will differ from another even if the same modifications are requested. Also there are different options of hybrid. There are different options for bearings, compressor wheel and turbine etc etc. So going to three different turbo speciailists and asking for a hybrid that has an uprated and clipped compressor wheel, ported inlet and uprated bearings could give you three totally different spec hybrid turbos. Also jbs are a vag specialist so I would imagine they have tried a few different variations of bearings, internals etc to find what combination worked the best.

very true, but any good turbo specialist, VAG based or not should do a very good job on giving a turbo some hybrid treatment, which should yield good results, similar to those the JBS04 produces

the AM04 turbo is a good example of this

 

[pj1985]

Yes but some k03 ybrids only produce 260bhp which for the extra £'s you have to ask is it worth it over the k03s. The jbs04 can produce much nearer 300bhp and although they are exspensive seem to constantly give good results. Swings and roundabouts I suppose.

hmmmm from what I have seen and heard, I hold some what judgement over the JBS04 putting out near 300bhp (but thats another story)

personally I would still rather do the hybrid treatment myself with a 3rd party

agreed though, swings and roundabouts

well lads what a difference to my car now with the ko4-001 turbo she bloody flies now.

so what is req to do the k04 conversion.

 

[pj1985]

The k04-001 is not a proper k04 its basically a k03s.

Any figures yet andy? A well mapped k03s will feel alot quicker than a k03 so be interesting to see what kind of power you have.

 

[bgasmatt]

so is a k04-001 a direct replacment for the k03
