S256 E.T. & 60# Inj
I have a 5k mile Bullseye Power S256 Extended Tip for sale, along with some 20k Mile 60 lb/hr Injectors.
The S256 has a DSM Hotside on it with an internal wastegate. It comes with the Oil Feed and Return flanges on it... so all that is needed it so bolt it on and hook up the Oil Lines. PERFECT CONDITION! No shaft play, etc.
S256 - $900 shipped
60# Inj - SOLD!
This turbo would be easily capable of pushing you over 400whp.It REALLY shines in the higher boost range, as well. As quoted from a really smart member when talking about the GT3076R:
Here's an EXCELLENT Review of this turbo with the exact same specs: DSMtuners S256 Review
Here's a dyno chart from this turbo with the exact same specs on an AWD DSM pushing 27psi:

By extending the ends of the compressor wheel, BorgWarner has effectively increased the pressure ratio, efficiency and flow of the entire compressor.
This gives the S200, S300 & S400 pressure ratios and efficiencies that can normally only be had with larger, slower spooling turbos. The extended fins do not hamper spool-up. The compressor wheel is designed to remove excess weight, reducing overall rotating mass. Of particular importance is the reduction of weight at the outer edges which is a major factor for reducing inertia. The weight reduction and where it is reduced allows these compressor wheels to spool FAST.
Another factor that increases the efficiency of the turbo as well as overall flow is the height of the compressor wheel blades. The BorgWarner extended tip version is over 20% taller than the standard 50 trim. The theory that the longer the air stays on the blades the more boost you can run and the more air it will flow thus improving the aerodynamics of the turbo. This extended tip compressor wheel is rated at more than 55 lbs/min vs. the standard 50 trim at only 49 lbs/min.

its been shown in many places that the s256 / s257 spool up about 400rpm slower then the 3076, but they seem to make about 20 more HP at equal boost.
pick your poison. a more efficient CHRA or a more efficient wheel.
