Does anyone know if it is possible to put both K04 wheels in a stock K03 housing without porting the turbo? and if so how hard is it?

 

I dunno about the ko4, but I know you cant put the ko3 wheel from an s4 into an a4, bc the compressor wheel is 5mm smaller on the s4, but the turbines are the same.

 

They have something like that. A while back they made a K03/K04 hybrid. It produced more power but wasn't very reliable

 

Its gotta be ported, and you need the beefier bearings to go with it. Best thing to do is check out the gpopshop. They rebuild K03's to K04 spec by porting them and putting in the k04 guts for like $450 or so. Search gpopshop. Or the website might just be www.gpopshop.com

 

check out some S4 forums, theres a load of info on these hybrids.

i have heard strong results, especially if u dont wanna go KO4$$.

i actually think an S4 guy here just blew his KO4's and is goin with the hybrids. talk to him
