Isn't the E05 bigger? But it seems like the Super K04 is better.

E05 has the K03S (as I like to call it) compressor side while the K04S has a modified (read bigger) compressor than a stock K04.

Not sure what the exact differences are, but lots of research will be done this summer

I would have to agree with him...from what ive heard sounds like the KO4s are good to go with

what may spool quicker or cost less. K04 will obviously look more stock, which some will be drawn to, regardless of other giveaways like the exhaust manifold. Since Neuspeed offers both, I doubt there will be many debates on which more is more reliable. I can't wait to the battles.

so what will be the debate?

I think someone should take a stock A4, and dyno, K04, E05 and K04S, all with the same injectors and sparks, plus software designed for each. That is the only way the debate would end. No exhaust manifold, and as long as each turbo uses same intercoolers (stock, duals, front) it will be a fair comparison.

If enough people donate to my PayPal I'll be the guinea pig, then I'll sell the kits to the people that donated =)

Nice thought on the donation program though.

Remember, size aside, the SK04 comes with an exhaust manifold, and the E05 doesn't for the same $.
