are all k04s the same?

[turboquattro068]

will they all bolt up to a4s, s4s, etc.. Are they all the same size? some look bigger than others, I'm confused with this whole deal, also do they come on some s4s?

[Squarrl]

No

1.8T need K04-015

[solowb5]

a longitudal 1.8t uses a k04-015, a transverse uses a k04-001, and audi TT uses a k04-023.

[turboquattro068]

what about the s4 deal?

[Squarrl]

i think they use K04-022

[sean1.8t]

they use the k04-026 and k04-027. COMPLETELY different

also, FWIW, the RS6 uses the k04-028 and k04-029. also, very different

[docurley]

There was never a OEM K04 for the A4 only the after market K04-15 which was made specially for the A4 as an upgrade option from tuning shops and not from Audi and so none of the K04 turbo's on other model Audi's will fit our cars.

What did a k04-015 orignally come off of?

The K04-15 came on the european market 190hp A4

[solowb5]

do you know the serial code?

[redflagquattro]

not off of the top of my head i dont, but if you google K04-15 you might be able to get a pic of the Borg Warner manuf. plate

No it did not they are just K03s remaped to 190bhp. trust me If I could get a K04 off the shelf from Audi we Brits would have bought them all and sold them to you guys for a profit

I had to buy one from the US to get it converted in to a Hybrin K04-23+.

K04-015 came off of the 225 TT and euro spec S3.

[AudiA4_20T]

K04-015 came off of the 225 TT and euro spec S3.

wrong, the k04-023 is off the TT and wont fit in our cars

[bandit]

my bad i forgot the 225 was transverse.
