Ko4 replacement

[Joshstan]

Hi all my cousin has an a4 1.8tqs with a ko4-15 upgrade but the turbo has died (letting oil through and excessive play in all directions)

just wondering on where is best to source a replacement.

Cheers in advance

Message beachbuggy. He does a much better unit than the Chinese k04 from eBay. It's that or buy another cheapie and throw it on hoping it's a good one.

Cheers for the reply I don't know why I bother helping lol as he just went and bought a Chinese one off eBay anyway
I give it 6 months before he has to buy another one

I told him not to run an mbc to hit 1.2bar and here we are!

It'll kill itself as it won't be running correct fueling or timing but hey ho

 

[Joshstan]

Hey ho indeed some people just don't listen

Surprised it doesnt just go into fuel cut tbh...

Probably has some shonky map on it which has disabled the factory safety limits.

The reason it's only 1.2 bar is cos it "goes loopy" at 1.3

He is now wondering why the head gasket is ****** and the turbo is dead

I'll be surprised if the Pistons are in a great way

My s3 was running 21psi on a revo map so his thought was that his could do the same on a 225 chip I tried explaining about fuelling but the response was "it's got uprated injectors and a 4bar fpr" reckons it is around 250bhp on a ko4-15

Won't keep up with my 330i auto (231bhp) and won't touch my s3 (255)

I give up!

It'd be closer 220. The 4 bar is std anyway. . No std k03 map destined for an a4 will be 225 the k03 is out of puff by 200.
