You want more power than a standard K04 kit, but don't want to spend $$$ for someone else's Stage 3 kit. You want a kit that is easy to install and comes complete with software and hardware -- no self-tuning required. You're interested in a smooth, wide powerband and derivability, not necessary the highest peak HP number on the planet. Think of the SuperK04 as a stage 2.5 kit. The NEUSPEED SuperK04 turbo features a larger compressor wheel and machined housing compared to a standard Borg Warner K04 turbo. The quick spoolup characteristics of the K04 family turbos is retained, but the midrange and high-end power is increased. The NEUSPEED Super K04 kit is much more than just a bare turbo. It's a completely engineered upgrade -- install it, turn the key, and start driving. Kit includes: SuperK04 turbo, NEUSPEED SuperK04 P-Chip, Cast iron high-flow exhaust manifold, Matched injectors, VAG 710N bypass valve, Denso Iridium spark plugs, VAG coolant temp sensor, N75 bleed jet, All gaskets, washers, bolts, manifold studs, etc necessary to install kit.
