Default '02 1.8T turbo question

Ok so I know I'll probably get flamed for it but I did a search and couldn't find a definite answere. So my question is, what turbo came stock on my '02 A4 1.8T. Is it a K03 or a K03s?

its a ko3s.

But bw never made a "ko3s". Its an improved ko3 and the turners dubbed it "sport"

The 225TT's have a ko4-20/22/23 turbo

i would actually say its a hairdryer not a turbo but hey, we all have our perceptions

car should have come with a k04-015 like some people upgrade too but if u want power, go with a GTRS/GT28 series or real power some people are even going with gt3071r now

the k04-15 and the k03 in the b6's are practically the same, hence the reason why you have 1+ software available

THANK YOU!! As for gt3071r's, those things are great street size turbos. Fast spool and big numbers. Not really HUGE like some may make it out to be.

indeed they are, just slightly larger opening (like .25 i think) and different turbines.... but the k04 makes a few (not many) more hp but if you compare the graphs
http://www.audizine.com/forum/showth...light=k04+dyno

it makes the power curve last longer... (of course its still not a BT but much better) someone else had a graph showing a 1+, 1+ and DSMIC, and k04 with dsmic and the k04 held about 30 ft lbs torque more throughout the powerband

held 30ftlbs more because youhave one running ~20psi and the other running ~30psi

the only differnce between a ko4 and a ko3 is the 1-2mm increase on the turbine. The ko3s uses a larger inducer, compressor inlet, and a more efficient 8blade compressor vs the ko3 12 blade.
