JGYCustoms B15 / SPEC-V

Besides the products listed below, JGY also has done the dirty work via installs and extensive research to enable the newer "Sentra" owners to achieve what the B13 and B14 owners have had access to for years... turbo motors/turbo kits/ and VVL's. Pictured below are 2 important break throughs in B15 technology: VVL install and turbo'd SR with 50lb injectors (on an automatic too!)

The Technology

B15 with VVL

Carl Davis' 2001 B15 with VVL SR20VE install complete with JGY clutch and Greddy MSS. Yes, that's right, we took out the roller rocker SR and installed a superior 11/1 compression ratio VVL motor. Estimated HP is 210 at the crank with this set up. Carl opted for JGY to use the Greddy MSS unit to control the operations of the cam lobe activations (check out our site for the details of this). This car is a daily driver and yes, Carl is actively dating more than one lady.

turbo kit

Jeff Proctor's 2001 B15 with JGY GT28RS turbo kit. This car is one quick ride, and it's an automatic! JGY intercooler kit modified to fit transmission. Utilizing Greddy Emanage, 50lb injectors, and running 1bar of boost. Let's get this straight....a factory Nissan ECU controls this car's functions, yet it is using a turbo, intercooler, over 2 times the factory size injectors, over 15 psi of boost, and is still equipped to pick up the kid from school to drop off with the mommy before heading off to the street meets. We have the Greddy Emanage program saved for our customers that want this set-up. That means our 22 hours of R & D and A/F wide band tuning is available for you with the click of button and no down time. Thanks Jeff for allowing us to use your car as our sample. Runs extremely well and quick making Jeff, one "FSTPAPI"

Greddy says: "It wasn't easy to improve on the popular Greddy SP system. But through customer feedback from over 10 years of use and testing, Greddy redesigned the SP as a full stainless steel cat-back exhaust system that is similarly priced to the original SP system. The new SP2 features a 304 stainless steel muffler canister with extra strong 430 SS end caps that feature a deep, high polish. Large, high volume mufflers provide maximum flow with a deep, pleasing tone and are especially effective when used on vehicles with aftermarket turbocharger systems. The unique outer curled oval tip (115 x 110mm dia.) is embossed with the famous Greddy logo. Employing state-of-the-art robotic seam welding, the single wall canisters feature increased rigidity for maximum durability and life. With over 35 types of internal perforated tubes, each SP2 application is specifically tuned for the best combination of sound and performance. The new SP2 also features thick walled (1.5mm); polished 304 stainless steel mandrel bent piping for better resonance and vibration control and enhanced corrosion resistance and durability. New lightweight, flared and stamped stainless steel flanges are also used to provide improved sealing characteristic."
