Ok probably asked loads of times before but im posting from my phone and dont have the search option. I remember reading a thread about r-tech nick saying that the only problem he found was that the wastegate sometimes didnt seal properly but was easily fixed by grinding with a dremel. Anyone here had any trouble with them?
-
Get on im getting one from Christmas lol nick will fix it for you depends how cheap u buy one aswell I know Dave iow hot one pm him
Cheers
-
Are these the new ones for 250?
-
The one I seen wat 300 good make aswell
-
I was thinking of getting one to punish it!! :evil:
My £900 OEM KKK K04-001 core has been ragged to the limits during deveopment for the last 13months.... I wonder if the £250 ebay kit could take it on my personal map on my AUM????
I have mapped a few for customers cars with ebay 001 and k03s turbos , which I dont push as hard as i would mine, but as far as i know they are all runnig strong still.
The ebay ones need a lot of time on the N75 boost control mapping as they will easy spike to 30psi+ generic on a stage1 or 2 map. The n75 duty need to be reduced by around 35% in the mid range to just stop the spike, then i had on with the actuator stuck shut and one which the flapper did not seal.
One customer is running an MBC and now peaking 25psi, since last summer..
-
I got a genuine 001 porter :cool:
If i couldnt have got one cheap, i would have got an Ebay job..
-
So is there any reason not to actually go with an ebay one? And would it see similar gains to a genuine kkk or would it be less?
-
depends if your a OEM only type of person, for 1/4 of the price, you pays your money, you take your chance..
might get this for 200 notes
http://www.ebay.co.uk/itm/Audi-A3-TT-Bora-Sport-Golf-GTI-1-8T-K04-001-TURBO-/350490147316?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item519ad739f4
Looks worse than the other though like XS power etc, probably the same unit though.
-
Yeah true. Wouldnt care about OEM to be honest just as long as it dont blow up 3 months down the line. Which one would be best to go with off ebay? (not got a good eye for it myself)
-

Visual build quality is poor, bad finish to castings. No uniform to how the wastegate gets setup and how it fits against the turbine housing. wastegate hole around 3mm to small vs the oem unit (which will cause raised egts, but can be ported out if your wanting to push the full flow) then picture of the one in the above ebay link will leak from the silencer cap.
Out the box they can be pants?.
BUT if you spend a bit of time checking it out and putting it right prior to fitting it then there will be no issues. (as you would test and check a genuine OEM unit)
If you want you can have to turbos sent direct to me I will check them out and put them right for you, you just pay the return P&P.

This is where I got mine from.... its come down in price since last year.

Nick, how much to rebuild a genuine ko4-001? If i send to you?
Bit of play in the shaft..

Send it to me and I will take a look, I can get the rebuild kits from mellets, plus have many parts in stock. If you get a fooked k04-023 then I can build you a hybrid like my current setup... :laugh:
-
Should have sent it up with Wazzzer :rolleyes: :grin:
What we talking roughly?

Money not an issues here, I work for hobnobs.. as long as the workshop has 3 maps booked each day I can find time to play and help others. Seal kits are around £20-£30, then a upgrade 360deg bearing £25

How is the hybrid setup doing?
And if we sent you just a std k03, how much would you charge to make it a k03-023 hybrid, thats if you would?
My turbo is going to be MAX to the balls for the 1st October when its at santa pod next, I just want to find the limits and how long it will last flat out.
My hybrid is based on the k04-001 turbine which give the HUGE 3000-5000rpm power band,, but if you get me a good k03 and a fault -023 I will build you if for free as part of testing and coming up with combinations and solutions for upgrade ideas.
-
Bloody marvellous, a packaged up turbo and enclosed packets of hobnobs it will be then.
Will be coming up to you soon, but need to swap my Saab reds for Saab yellow injectors as i have the VR6 maf to go on and you said will take a week of mapping to sort that out or buy 3'' ID maf, out of interest, how long will it take to map with Yellows + VR6 maf?
Got all the other goodies :smiley:
-
Calibra yellows like these? :wink:

They now yours mate? :huh:
-
So.if.I het the 001 off ebay and a shagged 023 you will build it for reasonable price AMD wat power we talking then.
Cheers
-
hay nick u can build me one for my trasher :P px for a PC lol
-
Nick, you wouldn't have the 023 parts needed as I have a k03 sitting in my shed that could use a bit of your knowledge and "sex" skills to hybrid it.
-

no, not a 001 from ebay!. he said a ko3 (not sure whether that includes a k03s) so thats a k03 and a K04-023.
i thought i`d have to say though, without brown nosing, nick must be a very genuine guy to do this for little or no profit, it just goes to show how much his hobbie-job and hobnobs means to him. :smiley: :grin:
-
Yea am like.he.said.his one is based on a 001 so if I get one ans send them both to home it will ne the same as his he knows what to do on the 001 the k03 is a gamble and a trial like he said wats needed for this hybrid turbo

There u go

The K04 on Nicks car is awesome :laugh:
-
one question about the k03 - k04-023 hybrid, is it done with a k03 or k03s?.. i only have a k03s :undecided:
-
Hi
I have done it with my 001 whih has a much more agressive turbine wheel vs the k03/s turbine side. Who ever opts for the k03/s with the 023 colds side will be the first one.. No way of knowing how it will react power delivery wise, my thinking is slower spool but 250-225 top end flow.
-
All this stuff in confusing me :(
Will the hybrid you guys talking about the nick can build be better than a standard K03s? Which is good for say 250bhp max?
-
Yeah think it will give bigger peak, but more important it pulls higher though the range. Area under graph wooooo :laugh:
-
Jamie16v, guess it wont matter as the housings are the same.
Wonder how quick the first damaged ko4-023 will be snapped up on ebay :rolleyes:
-
i got a spare k03s and i think i have a k04-23 in the shed :evil: i will check later.
Just need get the old girl an mot first
-
So wat I want is the.same as yours and I am right then
-
i got a spare k03s and i think i have a k04-23 in the shed :evil: i will check later.

Let us know if selling :wink:

Let the war begin
-
be clever about it! :wink:
-
wonder if a k04-049 is similar? :huh:

There is no right or wrong hybrid.. They are all amalgamation of bits knocking around even the units turbo builders send out.
Our units are all trial and error and so far no error has cropped up, just very strong power, and IMHO the results I am seeing are much better the what has been seeing from the brand names. I have see some of the branded of the shelf KKK hybrids suffer flow turbine flow and run high EGTs to make the quoted power, some make claim of 1.8bar boost peak but I am always worried to push that boost from them.
Today I fitted the blue spring back in my forge actuator and maxed the load maps out to request what ever the turbo can give.... which is in 4th gear with water injection 26psi peak and holding 24psi at 6300rpm... Its off its tits..... :laugh: Its going to stay like this now until the turbo fails, maybe a day or 2 or maybe a year or 2? If it hold up well at this power around 290+bhp 330+lbft then I will get the turbo built and run them at 24peak with the aim to hold 21psi which would work out at 310lbft @ 3200rpm and 270bhp to 6000rpm.
You need to drive it....... Its better than any big GTXX turbo setup I have driven, having full torque at 3200rpm and holding onto it is the buzz factor for me :laugh:
For all of you thinking about going for the k03-001-023 hybrid setup then your more than welcome to pop in to take a test drive in my car.
-
haha, if i were close enough i would take up that offer, but it would cost me about £50 in fuel to get to you and back..
defo thinking about hybriding though.. :smiley:

£50 for a huge grin!! and knowing you will NEED to have the power in your car..lol
Its going down santa pod 1/4 miles on saturday for my last RWYB of the year, I would like to crack a 12.9s 110mph with just the turbo.... long shot but already managed a 13.1s @ 108mph. Then whatever I can get with the aid of 75bhp shot of wet NOS (12.5s would be nice)
-
Ever tried/seen a ko4-049 compressor wheel in one?
-
go on nick, rub the salt in the wounds..lol... not got that kind of money at the mo but going into my own bussiness so this time next year we will be millionaire`s.. :grin: got a family car (scenic) now so i`m allowed to do whatever i want to the golf.. (says the missus). i have already been chucking all the interior in the bin :evil:
-

No, but if you get me a full BW KKK part number I will look up on the wheel specs sizes and work out what can be done.

Turbo the Scenic!! :grin:
-
Lol Yeh turbo the Renault Haha .
Nick I know that the K04 001 from backdraft is a bolt on using all existing oil lines etc . What else would you recommend ? Obv remap lol as I am needing one due to my acuatator still playing up lol thanks Nick
-

Y I man!! :grin:
How you doing Jonny?
Its 100% direct bolt on for your unsilenced version of Ko3s, its only the silenced ko3s which will need a smaller rubber pipe from the compressor outlet to the top hard pipe.
I would go a range colder on the plugs and water injection.. :drool: Apart from that and from memory of your engine bay setup I would say your about there.
-
Y I man I am great like Nick Haha how's you ?
Check ur pm Nick lol
Yep been looking ay water injection tbh lol I like :grin:
-
haha, had thought about charging the scenic but then its a top heavy pos so theres no point in having something that can only go fast in a straight line.
-
Strip it and drag strip it lol
-
How much is your water set up nick ans I want your turbo lol will let you know when I got my 2 turbos to send to you lol
-
Think it's around £250 (don't take that as gospel though)
It's a devils own kit and works a treat :cool:
-
very tempted with that send turbos up to u with hobknobs of course then wen i come up for the remap after crimbo have water system fitted aswell lol ummmm wat gains am i looking at wat power outputs? also if i change the injectors can i still run aum maf??
cheers
ps you got it on yours wazzer??
-
No not got it on mine (yet). It's something I'm considering in the new year though :wink:
-
just wondering if i should upgrade the turbo or go for Nos or even evetually both?... :huh:
-
Right thats my turbo flat out and the most power I have ever ran my car at!! :laugh:
Lets start timing how long it lasts flat out. (it needs to last until next Saturday when I run at santa pod again)
Car been running awesome today turbo and water injection flat out and running my NOS heated to 1200psi for the first time which works out at around 150bhp extra power from 4500rpm to 7800rpm.. I would say its kicked out a little over 420bhp..... and manged to push a Nissan GTR all the way up the gear box..
-
:grin:

-
how do you go about the balancing of the hybrids nick?. do you just line and mark up the spindle and turbine prior to dismantling or do you have the equiptment to balance?. i have thought about playing about with some turbo`s myself and i think if i could balance it up reasonably enough i would go ahead and build one.
i am looking at maybe just reconditioning a k04-001 but do you think i should hybrid and what with?.. is it worth using a 001 compressor wheel on a k03s or is that basically what the k03s is anyway?.
-
Any of these look any good Nick?

K04-001-023 hybrid FTW!!
-
I want nick crimbo im sending mine to you lol
-
Nick, this hybrid, i`m still assuming that it keeps the k03s turbine wheel and then accomodates the k04 compressor wheel. does the k03s compressor housing need machining for this and do you do this in house?.. not trying do dig classified information out of you, i was just thinking of saving a bit of money and doing some of the ground work myself.. (not machining and balancing though obviously). also would the k04 compressor housing fit onto the k03s core?
-

i get it now, i should have read properly to begin with :embarassed: lol
-
sorry to dig this one up again, but does anyone know if the k03 casings will mill out to fit full k04 core?..

Believe it will:

Turbo Upgrades
Turbo swaps are a serious investment in time, money, patience, and managing expectations. I've experimented with a T3 (laggy), two different K03/K04 hybrids, and a GT-15/20 hybrid (similar to K03/K04). Generally speaking, larger turbos flow more air and deliver more top end power; but smaller turbos spool faster and deliver more low end torque (better drivability). So far, the K03/K04 hybrid is my favorite turbo. It flows slightly more air than the stock unit and provides a modest gain of ~9 whp and 12 lb/ft in the middle of the band. I'm currently using a one-of-a-kind K03/K04 hybrid which features a K04 compressor in a modified K03 housing as well as a K04 turbine stuffed into a modified K03 exhaust housing ("regular" K03/K04 hybrid uses a K03 turbine). It gives up a tiny bit of torque in exchange for some top end power. Unfortunately, the top end yield isn't enough to make this turbo a worthwhile replacement for the K03/K04 readily available at BORA PARTS. But I believe an unexpected side effect of the larger exhaust opening is improved fuel economy when driving sanely. The K03/K04 hybrid is a direct replacement for the stock turbo.
-
okie, was looking at putting a full k04 cartridge into a k03 housing but seems the gains arent all that worth it.. i`ll keep the k03 turbine, it just makes more sense :tongue:
-
I'm sure the gains are a lot more than that statement, as I believe that's an old a$$ car that the guy is experimenting on without adjusting the ECU.
I'd imagine a k03-023 would throw you somewhere at the 245 mark maybe.
-
okie, was looking at putting a full k04 cartridge into a k03 housing but seems the gains arent all that worth it.. i`ll keep the k03 turbine, it just makes more sense :tongue:
Try it, I am going to try it over the next comming months, I just need to get anoter car up to full spec2 power running 100% before I bolt a turbo on. I have 2x AUG to work with over the winter months.
-
want mine as a lab rat?... :grin:

if i were to do this, would it be a case of just bolting the k04 cold side to the k03?.. the compressor wheel and housing maybe?.
obviously giving it new seals and bearings. does it really need assembly balancing?. from what i have read its not so critical on bigger turbos but smaller ones rotate at higher speeds blah bla blah.
-
o.k, digging up an old one but heres the plan..
buy a chinese/ebay k04-001 and bolt the k03s cold side to it.
i am going to recondition the core before i fit it, i know it`s brand new, but i want to fit bearings and seals from a reputable source.
so the only thing left that will be chinese is the turbine shaft and perhaps the hotside housing to accomodate the k04 turbine, unless i can make my k03s hot housing fit..
i may build the turbo myself if nick can source the recon kit for me, if not i will ask him to build it for me... :lipsrsealed:
-
Surely if you get a k04-001 copy it would be better just using that with a peak of 260bhp?
What's the k03-023 and k04-023 spew out figures wise?
-
Thought some one did a k03-023 with a nice write up. Looked like a lot of hassle as you had to bore out the cold side but you couldn't go to far due to the housings outer dimensions which was somewhat of a limit factor, but it was done.
-
K03-023 is a hybrid using the k03s housings and k04-023 internals. It has been done as I have one but I don't know it's origins.
I'm currently making one up and have spoken to jamie16 about it. The k04-023 can make a good 260bhp in an audi s3 /TT but in a k03s shell I'm not sure it will simple. The housings on the k03s both hot and cold are smaller so have a lower a/r ratio. Also one of the biggest problems I have encountered so far is that the k04-001 uses the same size compressor wheel as the k03s so fits comfortably into the housing where as the k04-023 compressor is bigger, I've had an original k03s compressor housing machined down to fit then k04 compressor but it produces it's own problems, in so much the outlet either becomes thin or you have a step in the flow. Exhaust housing on the other hand was no problem, again as the exhaust is larger it needed to be machined but there is considerable amount of metal so it wasn't a problem. My biggest concern would be the restriction in the inlet of the compressor and thus causing surge at high boost levels.
The other option I am taking is to use the inlet from the k04 housing and weld that to the k03s housing to give the required diameter. This would work.
My gut feeling is though that a good k04-001 will produce 240bhp a k04-023 maybe 260. Is it worth the extra effort to get a few more possibly unreliable bhp.. I'm not convinced. However it's an on going project for me so time will tell. If anyone wants any machine work done or needs turbo parts let me know.

I think I may have that turbo! Well certainly one similar.

Think it was you that did the write up similar to above before, for all the hassle the t304e kit looks sexy and a similar price which is what I would like to do eventually as its the same price as the k04-001 unit. Or it comes with a kit with manifolds etc... but then it becomes a case off uprating internals as well.
-
frm what i have read, the k04-001 compressor is smaller than the k03s. it has a bigger turbine driving a slightly smaller wheel, not as small as the k03 though.
-
yes, but its pointless using the k03 hot side, its too small..
-
true in some respect, is will spin better lower down the rev range, but further up it just runs out of puff.. and with a bigger compression wheel, i would imagine it would slow it down a very marginal ammount too.

Ive heard a a ko4-001 goes up to ~260hp
