I have been doing some quite extensive research into getting a hybrid k03 (k03 with k04 internals). From what i have read CR turbos seem to be a good bet for hydridising the turbo. is there any other good/reasonablely priced companies out there that do this sort of thing?

Another thing i would like to ask is all of the other associated parts i would need to get to do this. I already have a FMIC, CAI, 3" downpipe and exhaust, forge 007 dv and a forge tip on its way.
I believe i need to get better injectors (i have heard yellow top injectors from the vauxhall c20let engine would work) possibly a better fuel pump (LCR one?) and a 3" maf housing. anything else i need?

also, as far as mapping it goes i dont know where to start. would it be a stage 3 map i need?? I have read that badge bill knows his stuff regarding this upgrade so any info would be great!

Sorry about the essay, just trying to work it all out!

Cheers

Liam
 
Ive heard stage 3's required. Whered you get your downpipe done. Have you got your brakes done?
 
I got my dp from an ibiza on ebay and yeah I've got the uprated 312mm brakes
 
whats the sort of costs involved in a stage 3 remap?
best place to get this done?
 
Well badger i think deals with the hybrid turbos alot, but being in manchester hes miles from us both. your in petersfield arnt ya? Dont know exactly but, ive seen a figure of £700 somewhere before. so hope this isnt needed and just a £400-500 custom map is needed!
 
audi upgrades
cheers for the info guys

could someone please confirm if i can use the c20let yellow top injectors as and upgrade to my standard injectors?

Don't know about those but if you go proper K03 hybrid from the likes of CR Turbos, it turns it into what is effectively a K04... you will need S3/TT(225)/Leon Cupra R injectors, 3" MAF and a new TIP (as I understand the comp housing inlet is K04 size too).

There maybe some other stuff you need too...

Bill's stage 3 mapping is £550 + vat, thats what it has cost me to get my car done recently.

The Ibiza's I have see Bill map with the hybrids on produce very good power indeed.

could somebody confirm about getting a tip to suit the k04? as i was led to believe that the hyrbid was externally identical to the k03/s therefore having the same diameter comp housing.
 
LET injectors are EV1 the same as the injectors you have but 340cc @ 3 bar as opposed to the 325 from the TT/S3 so slightly more flow, and cheaper generally too.
 
so they would be up to scratch for the job for the hybrid? just looking at cheaper options..
 
I would of thought the tip would of been the same, as its a k03s with k04 internals, you send in your k03s it returns with 100 more bhp ! :D

And im from drayton just outside portsmouth mate.

Bill had someone today call him and say his CR Turbos K03 hybrid had a 49mm compressor inlet. (sure thats what he said)

The K04 on the shelf was 51ish mm, a K03 taken off a Polo was 45mm and a K03 on the shelf from a 2000 A3 was 39mm (IIRC)

Go figure... guessing the K03 tip may fit but I would prob measure the comp inlet to be sure.

Bill may be able to shed some light on this later...

the forge TIPs need to be trimmed for length anyhows, and do stretch over the slightly larger TIP on the hybrids I have seen.

the vaux yellow top injectors be good enough for the job then?
 
just a quick one, with the hybrid turbo, tip, fmic, new injectors, 3" maf and 4 bar fuel reg would 290 bhp be the max? also would it be ok to be an everyday driver?

thats pushing it to its max ! Badger was saying around 275bhp, it might be a bit mental as you have fwd, i wouldnt go bt but would go hybrid! (On your car.) Itll fly.!
 
i dont think you would get 290bhp.. 260-270bhp, and if higher flowing mani, wmi on it and advanced timing then you stand a chance of achieving another 15-20 bhp
 
could anyone recommend a good place reasonably local to portsmouth (hampshire) that could do the relevant remap/
 
west tuning are suspose to be good. The geezer used to or still does remap for the bmw race cars, so he must know what hes on about. he seems dear though. he wants £500 for a custom remap.

Where abouts are these guys? What would be reasonable price 4 a custom remap be?
 
You are gonna be looking at £600 of anyones money for a decent stage 3 remap.

Doesn't matter thats its still a K04.... FWIW, Bill has loads of experience with this very setup as its a popular choice of the Ibiza boys on SCN... Bill's stage 3 is £550+vat which is money well spent for the experience the man has IMO...

<tuffty/>
 
is there any well experienced remappers down south? i know most places dont go down the custom remap route.
 
Just spoke to the guy at west tuning, he recons between 6-800 quid for a custom remap.
he said if i'm changing the injectors and maf it makes things quite difficult therefore the price being so high, espescially on the earlier throttle cabled a3's.
 
I have been in comunications with Nick @ R-tech £389 will get you a bespoke map. Either emulated on the RR or from logs and tweaked.

I am hoping to have mine done on the RR as soon as i have fitted my Hybrid and won the Lotto.
 
is that the final price for the custom map? if so thats very good!

where abouts is r-tech based?
 
Thats what he quoted me with my hardware/ECU setup. It may be different for you, but not by ,millions

Leicestershire is where they are linky in the RR thread at the top

only 2 and half hours away, might be worth a phone call tomorrow i think!

whats your hardware/ecu setup?
 
018CJ ECU from a DBC A3 going onto a hybrided K04, on an a4 with high flow exhaust mani, exhaust, 360cc injectors 4 bar FPR
 
i just posted in you thead regarding you hybrid, is it the ko4 that has been hybridised or the ko3?
also was that a spare set of yellow top injectors i spyed in the picture?
 
Yer thats the man. he does seem expensive though. You sent off off for the k03 hybrid yet or are you still researching?
