GReddy GREX Oil Block Adapter Type E

GReddy Oil Block Adapter (Oil Cooler Kit) Campaign -  FREE Metal Label and Decal

To help clarify exactly which type of oil filter your Oil Cooler Block Adapter needs, use our FREE GReddy Metal Label and Decal in your engine bay.

If you have a GReddy Oil Block Adapter or GReddy Oil Cooler Kit, you can receive yours FREE, just follow the steps below...

(follow below...)

 1.)   Identify which type of Label you need for your correct Oil Filter Threads: 
        3/4-16UNF  or  M20xP1.5

        a.)   There are basically 3 types.   See (Figure A. below)  Compare the Center Bolt markings:
            b.)  The simplest way to identify the Oil Filter Threads from your Center Bolt is the length
              of the Threads: 
                  Short Threads 3/4-16UNF - H:13mm and Long Threads M20xP1.5 - H:20mm
        c.)   Center bolt:   Eng. 3/4-16UNF to Filter 3/4-16UNF  -  No Markings
                                     Eng. M20xP1.5  to Filter  3/4-16UNF -  Line on every corner of bolt hex
                                     Eng. M20xP1.5  to Filter M20xP1.5 -  Line around entire base (+ longer threads)
i.)  Pre-2017   The most common type of Filter Thread is the 3/4 x 16UNF - basically because all GReddy Oil Cooler Kits and Oil Block Adapters prior to 2018, all used either a center bolt adapter that was Engine: M20xP1.5 to Filter: 3/4x16UNF or Engine: 3/4x16UNF to Filter: 3/4x16UNF. 
ii.)  In 2017 GReddy introduced a new, more convenient Engine M20xP1.5 to Filter M20xP1.5 (center bolt p/n 12028813) and (oil block adapter p/n 12401119.)  Currently only newer Oil Cooler kits like the 2017-on Honda Civic Type-R and Civic Si / Sport Hatch Oil Cooler kits and new M20xP1.5 kits will come with this M20xP1.5 center bolt.
   2.)   Go to Instagram and search @greddyperformance and then "Follow" our account.
   3.)   Next take an engine bay photo(s) with your GReddy/GREX Oil Block Adapter from your
          GReddy Oil Cooler kit or your Custom Oil cooler kit, which uses a GReddy Oil Block.

   4.)   Post that photo (or photos) on your account with your Oil Filter Thread - HASHTAG:
          #GReddy3Q or #GReddyM20
  along with Tagging @greddyperformance

   5.)   We will then DM you on Instagram for your full mailing address or you can email us at
          shop@greddy.com with a link to your instagram post and  your full mailing address.

          (please be sure to let us know what size Oil Filter Threads you have:  3/4-16UNF
           or M20xP1.5) - * FREE Shipping for USA Customers / Int'l Customers, just pay shipping.

This Pro kit includes 4.0l tank capacity with a large 90mm throttle-body, and top feed fuel rail, and necessary weld-on flanges. For additional rigidity during high boost applications, it uses thick 3mm formed metal tank that is welded to a precision machined, grooved base, with six individual, internal velocity-stacks. Also pre-welded are the tuned primary runners and CNC machined, intake manifold flange with fuel injector ports. Another key feature is the unique, purpose-built  fuel-resist, ring-type gaskets that seal the manifold to the head.

    Collector tank capacity 4.02 l (normal ratio 200%)
    Welding required to attach throttle body flange, throttle cable mount and air port flanges
    Surge tank, base plate and runners pre-welded

    Throttle-body hose diameter 100mm, internal butterfly diameter 90mm with low-profile throttle shaft

New Universal RS-Ti Muffler and Tip Sets

  No Titanium Welding Necessary!

With the included pre-welded Titanium 2-bolt flange and additional stainless-steel flange and stainless steel muffler canister mounting bracket, you do not have to be able to weld Titanium to have a custom Titanium muffler exhaust system. Just weld onto the provided stainless-steel flange and canister mounting bracket. 

GPP Universal RS-Ti Titanium Muffler and Tip sets create new lightweight options for creating your own custom full Ti or hybrid Ti/steel exhaust system. In addition to the Titanium RS Muffler canister and tip, each kit includes a stainless-steel muffler mounting-band (to weld on mounting hangers), pre-welded titanium inlet pipe and 2-bolt Ti flange, as well as a matching composite gasket and stainless-steel 2-bolt flange (to adapt the kit to steel piping.) The kits are available in a 3.0” (76mm) and 2.5” (63.5mm) piping sizes. Our signature high quality, straight-through, universal RS racing sport muffler design offers exceptional flow with a clean, yet aggressive exhaust note. And with the RS Tri-bolt removable Tip, optional RS inner tip silencers and tips can be purchased separately for even more customization.

Dsport Forced Induction 86 Challenge Winner - Video

The GPP GTX2867R Gen2 Tuner Turbo Kit wins Dsport Magazine's (Forced Induction) 86 Challenge, with the quickest track lap, the second highest dyno numbers at just 10.7psi  without dangerous "boost creep" (4.5psi lower base boost level then one of the other turbo kits) and second highest overall Editor's Driving Impression score.   (for more details see below)
Watch Dsport's Review Video...

RECAP: of the 86 Challenge

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

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)

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.

Two New GReddy Exhaust Arriving in February

The EVOlution GT exhaust for the 1990-96 (SW20) MR-2 Turbo is styled to resemble the legendary Power Extreme II MR-2 exhaust of the late 90’s-early 00’s. This makes the Evo GT the ideal exhaust system for a modern, period-correct SW20 MR-2 build. This new and improved version follows the same beautifully laid-out dual off-set muffler with extended wrapping tips, but it now, incorporates superior construction, improved stainless-steel materials and precision tig welding. The more compact, dual, straight-through EVO GT muffler canisters allow for great flow for both stock and upgraded turbo 3S-GTE engines. Like all GReddy EVOlution GT systems, this 304 Stainless-steel exhaust carries a limited lifetime warranty.

-- ---- - --- -- 

The Supreme SP for the 2006-15 (GSE20) Lexus IS350 / IS250 features sophisticated exhaust note with an aesthetically functional design. The classic dual oval muffler axle-back system with large free flowing 63.5mm (2.5”) piping is comfortable to drive. Thanks to the two large SP mufflers, it has excellent sound suppression at idle and cruising. In spirited acceleration, the straight-through design makes the exhaust comes to life with a deep rich GReddy sound. Tradition double wall GReddy tips on each SP best matches the styling of the vehicle. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty
