Finally Installing A New KO4 Hybrid Turbo On My B6 A4

[@Frghjdxcgydfhgf]

Hey! Great video. Did you do ECU reprogramming for your new turbos?

[@11BabaYaga]

I’m looking into getting a b6 rn and these videos make me want to get one even more. These cars seem fairly easy to work on and reliable the 1.8

[@marktsmotivation]

I have a K04 Hybrid also. I'm about to do a tune because I'm getting an overboost code. I love the extra power, though.

[@doubleosgarage]

What tune are you thinking about going with? I still havent decided ive been chasing s few codes the only code i have left now is a secondary air pump wrong flow code. I did find s small vacuum leak near the combi valve im thing of just doing the sai delete first

[@marktsmotivation]

@@doubleosgarage I have a guy here in Maryland who has been tuning European vehicles for 30 years. He's doing a custom tune. I hear that he has an Audi R8 that's running 7's at Capital Raceway.

[@esvenkirinoguerra8840]

It's actually a video that has been very helpful to me, it's just that I have a doubt about what size the 3 screws that hold the turbo are.

[@CarlosSanchez-iy5gr]

17mm

[@bkokkok]

hey where did you put turbo support bracket on your right side at 1.30 ? I couldn't see rest of the video.

[@Kishi-iw5vx]

not sure if your gonna reply to this since how late i am but where did you get the intake pipe for the turbo??

[@zoranmadarevic3630]

Hi mate, nice video, after install, i saw in comments u using stock fuel map, and probably stock injectors, do you feel any difference in acceleration and spool speed of the turbo, more sound? Total hp gained? Thanks... I have stage 1 1.8t C5 Audi with custom intake and exhaust, car goes good, my k03 charges 1.1 bar now, around 210hp, but i think its at the limit, what do you think should be good idea to swap this system k04 hybrid...?

[@cleanname4439]

yes but u should minimum get a remap to make use of the bigger turbo

[@killascottymac]

whats your tire specs, i want mine to stick out like that lol

[@ZEV79]

I own the same car and 164k on the clock, i would like to upgrade but what K04-015 brand should i install ? Awesome video, thank you 🫶🏻

[@doubleosgarage]

That all depends a safe bet would be Borg Warner. I went with cx racings k04 hybrid because it was cheap and temporary since my factory turbo was blown. I do plan on building the motor and adding a bigger turbo in the future so it didnt really make sense to spend so much on a turbo that i dont plan on keeping

[@carsaremything.3051]

Great video can we get a sound check or a pov?

[@doubleosgarage]

Sure can! I just wanted to break in the turbo first

[@Boosted_avant]

@@doubleosgarageany check engine light from the high flow cat?

[@doubleosgarage]

@Boosted_avant no so theres 2 ways to avoid this you can either have the car tuned to bypass the check engine light or you can do what i did and get an o2 spacer

[@BIGJ0E]

Are you running the factory intercooler too? If so, do you plan on upgrading to a front mount? Cheers

[@doubleosgarage]

At the moment i am running the stock intercooler but i do have a front mount and will be making a video soon!

[@BIGJ0E]

@@doubleosgarage Ohhh boy lol. Subscribed. I have a 1.8t B6 too and your vid made me buy that same K04 hybrid. Sometimes you just gotta grab the boobs and jump brother.

[@doubleosgarage]

I love the turbo so far for the first 1000 miles i did take it easy. I never gave it more than half throttle.

[@BIGJ0E]

@@doubleosgarage Good to know. Also I have those same headlights with LED bulbs and I did notice some corrosion inside one of the connectors to the main headlight harness. Just something to keep an eye on.

[@doubleosgarage]

Thanks will do

[@gijssout1846]

nice vid 👍

[@doubleosgarage]

Thanks!

[@Kv3Rn1s]

How much more power did you gain from adding this turbo? Great video! :)

[@doubleosgarage]

Im not sure tbh the turbo was on its way out if not already blown and the clutch was slipping when i bought the car. The car isnt tuned so im sure it cant be to much more.

[@Chino-kv2mu]

Not a question bout turbo , but can some 1 help me with this , my speedometer stopped working and can’t find the speed sensor anywhere. Some ppl say it’s behind the oil can but that’s not it . 2003 a4 Quattro 1.8t thank you And love this vid by the way helped me a lot

[@doubleosgarage]

Send me a dm on ig ill send you a video where its located

[@JeremyGreiner-t2y]

I ran a 20psi tune on my 2005 a4 1.8T and upgraded to a Ko4 hybrid, TT, injectors, and a 20psi tune for the KO4. Motor doesn’t whistle like it used to and doesn’t seem to be building boost…even with a 20psi tune. Any ideas?

[@doubleosgarage]

It sounds like your car is stuck in limp mode. Hard to say what it could be id recommend scanning the car and double check that everything was installed properly

[@tntxjosh8667]

Where did you bought the ko4 hybrid turbo?

[@Acejh85]

Have you ever heard of torque to spec

[@felixrachel]

What upper grill is that? Where did you get it?

[@Itsmeart1988]

You are really holding the car back installing a bigger turbo with a stock intercooler system. Your timing your IAT and your overall power will suffer.

[@doubleosgarage]

I am running a front mount intercooler now i just didnt film the install since i did it the same time i changed my clutch.

[@Itsmeart1988]

@@doubleosgarage oh, perfect. We did a CTS intercooler and a Valeo single mass conversion clutch.

[@doubleosgarage]

Nice i almost went with that intercooler but i didnt want to cut my crash bar so i decided to go with a front mount set up from cxracing since im also running their ko4 hybrid turbo. I dont plan on doing anything crazy to this car its just a daily driver/ winter beater so i went with McLeods “stage 2” daily clutch since i do plan on adding a tune and bigger injectors.

[@cazzuz6081]

is it ok to run a 90 degree on the o2 sensor? i got a 1.8t so its the same

[@darrenfitzpatrick6490]

whut bro what are those wheels? they look great

[@doubleosgarage]

Thanks! They are ESR CS-15s

[@squidgypants722]

Would this be the same turbo I need on my 1.8t 2004 with the BEX engine. 🤔 Thanks.

[@doubleosgarage]

From what i read on their website this turbo would be for the AMB engine. Im not sure if it would fit tbh. I would try to find one made for the BEX engine just to be safe

[@squidgypants722]

@@doubleosgarage Thank you very much for your reply. Merry Christmas from England. 👍

[@Sweettoothb6]

What was all needed for the ko4 swap and how.is the turbo hanging any issues

[@doubleosgarage]

No issues with the turbo so far. All i bought was the turbo, turbo lube, and new oil for an oil change so the turbo got fresh oil on its first start up. Tbh as long as you do the install correct and dont beat on it from the start i dont see why there would be an issue. Ive only been running the turbo for a few months and its been working perfectly fine. I recently upgraded my clutch since it was starting to slip i should be ready for bigger injectors and a tune now.

[@Sweettoothb6]

@@doubleosgarage sweet you did a video of you changing the clutch . I am considering swapping my turbo out for the same one you got

No unfortunately i didnt film changing the clutch. I wanted to film it but with the time frame i had it wasn’t possible

For the most part i would say the seals are blown. Some blow by is normal but not alot. They are 20 year old cars so the turbos going to go out eventually.

What tuner do you use or do you drive with stock tune?? I got new spark plugs and the r8 coil packs for my car i dint think i would need a tune but my car is acting up also have high flow cat what do you think problem is??

[@doubleosgarage]

@misaelguevara1375 atm im running a stock tune. New spark plugs and coils shouldn’t require getting a tune. I would check if all the coil pack connectors are fully connected. From my understanding a tune isnt required but recommended with a high flow cat. Is your car throwing any codes?

The turbo has nothing to do with the trans. I dont see why the stock trans wouldn’t be able to handle a k04

@@doubleosgarage That's not a hybrid, that's just a knockoff k04-015. Being a drop in replacement doesn't make it a hybrid. Wash your hair.

[@doubleosgarage]

If the front half of the turbo is a ko4 and the rear half is a k03 it is a hybrid turbo…. This k04 hybrid will not fit a k04 exhaust manifold

What headlights are those?

They are the Spyder fiber optic style projector headlights from Pro Tuning Lab
