k03 to k04??

[gti314]

Is the only only difference between k03 and k04 the internals of the turbo?? If so why hasn't anyone just rebuilt there k03 to k04...The link is a shop that does it..

Interesting.. I'm sure there must be some reason people dont do this. It said they swap the k03 wheel for the k04 wheel for 200 but is that really the only difference between the two?

Could likely be the K03 from the MK4s.

They don't do our turbos.. this topic has been beaten to death on this forum and on vwvortex.. search for it

The two turbos look the same, however they are completely different.

The CHRA (internals, turbine/compressor wheels) are larger and made of different materials.

The Compressor housing on the k04 is larger and features a turbo speed port for turbo speed gauges. Fitting the K03 in the K04 would require machining the inside of the K03 compressor housing.

The compressor housing on the k04 does not have an integrated DV like the K03.

The wastegate on the K04 is different.

The Exhaust manifold and hotside of the k04 turbo is Stainless steal rather than cast iron.

The N75 is the same.

Awesome thanks for the info i noticed it wasnt for our cars.... is porting and polishing a bad idea on our turbos/manifold

there is a guy on this forum who has done it and claims he great results but i would recommend you go straight k04 and dont bother

Just buy a K04 new for a $1000ish and put it in... with injectors,gaskets, and programming

 

[majorahole]

couldnt you just swap comp housings too, if the wheel fit and you could find one??

got anywhere to get a cheaper one that 1,300 thats what ecs has k04s at right now

gti314, If you wants to wait a bit, we'll have a fully integrated solution that should be pretty cheap. You'll have no need to buy extra parts to reroute the DV as it will be all integrated on the turbocharger.

The TSI version of the kit, including software, sells for about 2,300 on sale right now, so just add injectors to that price and you'll basically know what it will cost from us.
