Well I've done alot of research but am still unsure as to which turbo route I want to take.
BT = lots of potential but a good setup costs alot when you include tuning, clutch and intercooler

K04 gives you significantly less turbo lag and can be done without changing many parts, but won't give you as much high end hp. Also an advantage to this is that when I get power hungry I'll buy an S4 and swap the K04

So I'm looking for advice from someone who has experience with both setups? How is the performance to 60? beyond 60? What cars will I be able to keep up with? WRX, Mustang, S2000, GTI, 350z, RX8

Overall I'm looking for a well rounded car, but I like hotrodding and chirping tires so I'm willing to sacrifice some top end to get rid of turbo lag
Any input would be greatly appreciated, especially dyno charts, timeslips ect. I’m not strictly limited to these two setups

Thanx

skip ko4.. lots of people have had problems on AW with the GT2X blowing at around 5k miles. so not too much luck with it.. i would go with the GTRS eilm to beat all those cars you mentioned plus the software will be a little easier to attain

 

you cant take the ko4 out of your a4 and put it into a s4. obtw the s4 requires 2 ko4's

 

ya, totally forgot to mention that^

 

yea i know the 2.7 is bi-turbo but the K03's aren't compatible huh?

 

nope they attach to the manifolds differently
