Our NEW N55 Stage 1 upgrade consists of a brand new N55 turbo, custom cast and manufactured for VTT, this is coupled with a VTT custom reverse billet compressor wheel and brand new stock turbine. Stage 1 upgrade uses the stock plastic DV, but with the option to include a custom VTT / Forge DV system, or a GFB DV+ system to replace the stock plastic DV parts which are prone to cracking, and leaking. This upgrade will support 40-75 WHP over a stock turbo with stock spool and plenty of flow to redline. Turbo upgrade is a complete bolt on with no changes to water or oil lines and is undetectable by the dealership.

There is NO additional required core charge with this turbo.

Add the install kit to make sure you have everything you need to get the job done right!

Every VTT turbocharger comes with a 1-year limited warranty. Please read our Warranty / Emissions Disclaimer when checking out for more details.

Install package price is for turbo installation ONLY, added parts such as Inlets, fuel system parts, etc will be additional labor.

Engine oil choice with upgraded turbochargers is a very important aspect for longevity, we only recommend 40W oils and higher, with high Zinc, and Phosphorus content, for high shear strength.
