well my turbo finally took a shit but i guess i got my money out of it it lasted 135K miles 🙂 ![http://img.photobucket.com/albums/v209/pinfieldrx7/turbo/turbo005small.jpg](http://img.photobucket.com/albums/v209/pinfieldrx7/turbo/turbo005small.jpg) ![http://img.photobucket.com/albums/v209/pinfieldrx7/turbo/turbo006small.jpg](http://img.photobucket.com/albums/v209/pinfieldrx7/turbo/turbo006small.jpg) ![http://img.photobucket.com/albums/v209/pinfieldrx7/turbo/turbo004small.jpg](http://img.photobucket.com/albums/v209/pinfieldrx7/turbo/turbo004small.jpg) ![http://img.photobucket.com/albums/v209/pinfieldrx7/turbo/turbo003small.jpg](http://img.photobucket.com/albums/v209/pinfieldrx7/turbo/turbo003small.jpg) this is what im looking at picking up as a replacment for $800 The stage 3 turbocharger upgrade for the S4 RX7 consists of a modified 60-1 compressor wheel, T04B compressor cover package with dynamic seal backing plate and dynamic sealed thrust collar. Turbine wheel is clipped to spec to decrease back pressure and help stabilize rotating assembly RPM. The Rotating assemblies are balanced and blue printed to minimize vibrations and to give you a more reliable turbocharger upgrade. The stage 3 turbocharger has a 360 thrust bearing option for the people running 15 psi or more. The wastegate is machined to 35mm, and the turbine housing inlet is ported (optional with purchaser b/c of the factory twin scroll set-up). The stage 3 is capable of 340-350 RWHP at or below 15 psi on a properly modified car. The car will reach peak boost at an estimated 4K rpm. ---

yes it is bigger than stock but not big enough to consider an upgrade. ---

> [@BoostedITR41](#): > > yes it is bigger than stock but not big enough to consider an upgrade. if i go much bigger im gonna have huge lag that to4b housing with a 60-1 clipped wheel hits peak boost at 4K RPM i dont wana go much further than that and im only looking to run 12-14 PSI that turbo should support my goal of 350 HP with a reman ported motor with no problem so there is no reason to go bigger and cause more lag ---

> [@BoostedITR41](#): > > yes it is bigger than stock but not big enough to consider an upgrade. a 16g will do a hell of a lot more than what a 14b can do on a DSM and its barely bigger than stock… :dunno:
