I'm sure this has been around the block a few times but, really don't have the time to do a bunch of searching, so here it goes, have an 01 2.7t 6 SPD. Lh turbo is going out, have GIAC software, I have heard lots and cons to go ko4's but if I do do I have to besides the inlet pipes, have to change fuel pump and injectors?, and change software?, or can I just change turbos and leave everything else as is?.
Tnx

There can be a lot of opinions on this upgrade but IMHO the bottom line is, if you are willing to spend the coin to finish the upgrade go with the K04's. The turbo is the heart of the whole system and the air/fuel ratio will be off if you only upgrade the the boost capability without upgrading the fuel flow delivery. It is not for the faint of heart, your all in or just replace the the K03's and enjoy the ride.
