PRO Surge Tank Kit for 2J Swaps

Customize it to work with your 2JZ application!


GReddy 2JZ PRO Surge Tank Kit


(JZA80) 2JZ-GTE in custom applications
Designed specifically for custom applications with 2JZ engine transplants, the GReddy 2JZ Pro Surge Tank Kit offers the versatility to best match the throttle-body inlet angle and vacuum/air ports for your engine bay. 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.

2JZ Pro Surge Tank Kit includes:

    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
    Tuned internal velocity stacks on each runner
    Primary runner length 130㎜, OD 14.0mm ID 13.0mm
    Specially designed and manufactured O-ring style gasket provide superior manifold to head sealing for each runner
    Throttle-body hose diameter 100mm, internal butterfly diameter 90mm with low-profile throttle shaft
    Fuel Delivery tube for 14mm top feed injector (compatible with Nissan R35 VR38DETT factory injectors)
    Compatible with OEM factory Idler Control Valve and TPS Throttle Position Sensor

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.
