C34 Stagea Stuff: Engine

Radiator

1993 - 1998 R33 Skyline
(Automatic transmission models have a routing through the bottom of the radiator to warm the fluid up during the winter, and cool it during the summer. You can opt for a manual transmission radiator, and bypass the radiator cooler and strictly run just the external cooler located in front of the radiator. If you do this, you will need to add .5-.75L of Castrol Transmax or Nissan Matic-J Transmission Fluid.)

O2 Sensor

Optional Swap

1990-1996 Nissan 300ZX

Will require reusing and re-pinning the old plug. The 300ZX uses vertical blades, whereas the Stagea uses horizontal blades. Use EXTREME caution when removing the old plug off the mounting point.

Alternatively, you CAN swap the plug off the vehicle harness side from a 300ZX, which would prevent you from having to keep re-pinning the o2 sensor plug in the future. Check your local scrap yard!

Fuel Filter

K&N PF-1100

(Amazon Link to the one I bought)

Fuel Injectors

NOTE! These options are only tested on the NEO fuel rail, which uses a Top Feed injector.

The Non-Neo uses a Side Feed injector.

16600-AA500 340cc (Stock Fit RB25DET)

16600-EY00A 380cc (Stock Fit 350z)

16600-38B0A 550cc (Stock Fit GT-R35)*

*Tuners LOVE the GTR Injectors due to the consistency of the spray pattern. You WILL require tuning if you're installing these injectors though.
