Yea I wouldn't spend the same amount of money on a reworked stocker as on a true big turbo. I know they have different internals but the points or restriction are still the same aren't they?

Yep...its the turbine side of the housing. Its freakin TINY! So even if you replace the turbine and compressor wheels, the housing is still ultimately the main restriction. Its the same reason why our turbo's crap out at 20psi where as the same turbo on an S4, or even a k03 on a VW is capable of pushing 24psi no problem.

This is the same reason why I don't like the Internal WG set-ups that ATP sells. It looks like a restriction there as well.

I'm guessing you didn't severely damage your block so LKQ might not be the right way to go.

Just mount that baby on the roof!

I wonder what the lag is like with that thing!

The only issue with the IWG ATP turbo's is they would sometimes experience boost creep. I believe in their new revisions they have fixed that problem. In any case, EWG is the way to go and nothing sounds as mean as VTA once you hit boost :D:D

Just make sure the outlet isn't pointed at something important. :)

Have to have a dump tube too, heh. Someone tried one run without a dump tube and damn near melted everything in the back of the engine bay.

B5/S4 stock has two K03's, and they're efficiency is done @ 19psi peak, with a taper to 14 @ redline, and that's even pushing it. The Stage 3 upgrade turbo's are K04's and they are within efficiency until 26-28psi and @ 21-23 @ redline, but keep in mind that you're dealing with a 2.7L TT 6 cylinder, not a little four banger. Also, the BW,KKK K04's for the VAG platform are completely different than the one in the MS6/MS3.

Just get the Russian Red and be done with it. It only weighs a minuscule 94lbs, and costs around $55k
