GPP GTX-R Tuner Turbo Kit Wins Dsport's 86 Challenge

    The Results are in the Oct. 2018 Dsport, Issue 198

GPP GTX2871R Gen2 Tuner Turbo Kit

With a winning overall score of 239pts, the Greddy Performance Products GTX2867R Gen 2 Tuner Turbo Kit FRS Challenger takes Win over the other Forced Induction challengers...

    • 239pts. - GPP tuner turbo kit      - (268.70hp / 208.38ft-lb @10.7psi)
    • 236pts.  - HKS turbo kit                         - (285.63hp / 221.05ft-lb @15.22psi)
    • 199pts.  - Edelbrock supercharger kit   - (248.29hp / 182.45ft-lb @13.79psi)
    • 193pts.  - Vortech supercharger kit       - (228.20hp / 183.30ft-lb @10.5psi)
    • 148pts.  - AVO turbo kit                         - (253.01hp / 222.85ft-lb @10.7psi)
    The GTX2867R Gen2 Turbocharger in the GPP Tuner Turbo Kit is rated for 550hp and is easily able to make even more power by increasing the boost level (additional engine strengthening required)

    NOTE:  For reliability reasons, GPP doe not recommend boosting more then 12psi on a stock FA20 engine.  Overboosting can lead to premature engine failure.   

    To equalize all competitors, each car used the stock oem FA20 engine with the same: engine oil, radiator, oil cooler, coil-overs, anti-sway bars, brake pads, brake rotors, wheels, tires.  They were also tuned by the same tuner on 91 octane.


    The GPP Turbocharged FR-S had the quickest track lap, the second highest dyno numbers (at a 4.5psi lower base boost level) and second highest overall Editor's Driving Impression score.

    GPP GTX2867R Gen2 Turner Turbo Kit - p/n 11518000

    Super Street Magazine's Week 2 Wicked S2000 Build Up

    Just last week the GReddy team participated in Super Street Magazine's first FB live "Week 2 Wicked" build up of a 2001 AP1 Honda S2000. The main power-adder selected was a prototype of our newly revised and updated GReddy S2000 Bolt-on Turbo Kit, GPP RS-Race 3" exhaust and Profec, electronic boost controller.

    The end goal is to release a GTX-R Tuner Kit by Sept.-Oct. and complete CARB testing in the coming months... stay tuned for future updates!

    For a SUPER STREET recap of the build please see:
    Day 2   Day 3   /   Day 5 

     Day 2 at the Super Street garage, the GReddy team installed the GReddy S2000 AP1 prototype bolt-on turbo kit featuring a Garrett GTX2867R Gen 2 Turbo... see SUPER STREET Online for more!

    Day 3 the GReddy team returned to complete the turbo kit install with injectors and the fuel management.  To optimize the performance a GPP 3" RS Race exhaust with optional Titanium tip and Profec electronic boost controller was added.

    On Day 5, the final day, Super Street and Week 2 Wicked S2000 made their way down to the GPP headquarters in Irvine, CA to dyno and verify all the performance modification.  The 120hours, Week 2 Wicked, GPP turbocharged S2000 produced a conservative 260whp @ 10psi on standard 91 octane gas.  Thank you to Super Street crew for including us in your build!

    Look for more updates on our new AP1, AP2 and AP2 drive by wire,  S2000 Turbo Kits coming soon...
