I knew there was no K03 sport! Aha! I was right! *evil laugh*

That's awesome. They say that the K04 is good for 220 horsepower... no? But doesn't the TT have 225 stock with it... and haven't people hit 270~chp with the K04? I think I'm missing something.

 

ko4-20/22/23 is bigger and flows more cfm than the ko4's listed above.

Also as you read, there is no ko3"s" but it is bigger than the 2000 and down turbos. So if you have a 01 170hp car, "upgrading" to a ko4 is pointless.

 

but y is that? y would people make a turbo for a car if they know people wont get power out of it. all its good for is a replacement turbo and thats it i dont like the KO4s they dont seem to put out alot of power the most ive seen on a A4 with all the supporting mods and a good file to work with the turbo is 220whp and 250 tq. that with inake, fmic,fpr,intakehose,fullexhaust and downpipe,a better clutch,boost controler,and other stuff that i cant think of rite now. can sumone please clear this up for me as of y this turbo sucks
