A3 boost hunting!

[Curt]

I'm not talking about power - I'm talking about delivery. The K03S will never put out 280... you'll struggle to get that out of a K04. Max on a K03S will be around the 240 region. But, it'll be much more drivebale and much less laggy. The K03 is a straight swap of course - it's the same turbo as you have now but with a different compressor. There is in fact no such thing as a "K03S", it's just a later type of K03 that's been given that nick name. Be wary of turbos that get called that but aren't, some of the 180bhp cars have a normal K03 with a different actuator.

K03S was the way I was going to go, it'll still be a quick car.

As was mine, I don't know what Sam means.
