After doing some research into sourcing one of these bad boys I’ve stumbled over a the Revo KO4, is anybody running this at the moment? Would it be worth the difference in price in comparison to the OE counterpart?

I do not know anyone with the revo K04 kit. It is just a Borg Warner K04 and they may have done some clean-up on it and got rid of the turbo muffler...so it has a direct outlet. Scroll down (link below) to see pics and they use the word "competitor" without stating which that would be. Is it a clone or genuine BW before revo cleaned it up...who knows. I would say compare the BW K04 and a turbo muffler delete. Additionally, if you see the mess those pics show inside the BW K04 turbo inlet...clean it up before installing it and voila...you have a revo K04. Power output would be no different as revo didn't modify the compressor or any internals. https://www.urotuning.com/products/revo-k04-turbo-kit-exc-software-transverse-2-0t-fsi-rt991m100300Since I was planning on taking it to R-Tech to get mapped in I wasn’t too fussed about the “stage 3” package that was offered with it.
I may just find myself pieces for the conversion and get a second hand one reconditioned I guess.
Thanks mate

Get a brand new turbo and K04 injectors, then source everything else from ebay. It's about £1500 worth but it's better to put the extra into the main components rather than sticking secondhand stuff in of an unknown history/condition.How about getting it reconditioned pudding?

If I were you, I would just get a base spec turbo and all the other bits, bung it on and just go for a mild remap and see what you feel about it. You won't get much more than 330-340hp unless running everything on the ragged edge......and that won't be possible on an AXX block anyway as it has a higher compression and weaker pistons than a K04 engine.
Switching from the K03 to a K04 is already a big step up, so take it easy initially. I'm not trying to be your Dad, just trying to stop you from blowing the engine up :grin:

You mean buy a scrap K04 and get it refurbed? Yeah that's an option. Personally I would only go to TurboTechnics for this service, but tell them you just want a standard rebuild with 360 degree bearings. If you go for a hybrid that will add extra work to the mapping, and therefore cost.So the KO4 I’ve sourced is off an S3 about 40k miles I will 9/10 get this checked out and refurbed before installation, as I’ve already swapped the block for a BWJ from the cupra but are using my ancillaries I should be good for 340 providing I switch out the injectors and intercooler right? I always had plans to KO4 the car but it’s being dictated on the cars terms and not mine

I’ve had a little root around of turbozentrums website and I’ve seen they do an injector clean too so I might get them both checked over.Sent from my iPhone using Tapatalk

OK, things are sounding better now. A 40K old snail might not even need a refurb :happy2: I don't know the spec of the BWJ. Is it a CDL/BYD equivalent? If so, it will have the lower compression and better pistons/rings etc so you can run more boost :happy2:So the BWJ came out of a Seat Leon Cupra K1 which ran a KO4 out of the factory so in theory it should hold up the same as a BYD/CDL on R-Techs website it did fall under the same category as those.
I will be able to get a better indication when I get around to inspecting the snail in person then I’ll make the call to have it refurbed not, I think the injector clean will be a must.
