How do i install a 2015 mazda rx-7 rz-1 turbo kit: a 101 guide

so you wanna slap an RZ‑1 turbo on your RX‑7, huh? here's the low‑down

1. parts list

• RZ‑1 turbo assembly (turbine, compressor, housing)
• intercooler kit (oil‑cooled)
• oil‑pressure regulator
• new intake manifold
• upgraded fuel injectors
• wiring harness
• ECU flash

2. prep

• remove stock turbo (unscrew 6 bolts, take out the housing)
• clean the oil pan, replace gasket
• check the crankcase for any wear, replace if needed

3. mounting

• bolt the RZ‑1 housing to the engine block
• align the turbine shaft with the crank
• torque specs: 20 ft‑lb on main bolts, 15 ft‑lb on turbo bolts

4. plumbing

• run the intercooler piping from the turbo to the intake
• connect the oil feed to the RZ‑1 oil cooler
• make sure the fuel line is rated for 2000 psi

5. wiring

• swap the old harness for the RZ‑1 harness
• connect MAP, TPS, and boost sensors
• flash the ECU with RZ‑1 firmware

6. testing

• start the engine, let it idle
• check for boost leaks
• monitor oil pressure, temperature
• pull a quick dyno if you have one

tips

• keep a hand on the throttle while starting, avoid surge
• use a high‑octane 93+ fuel
• if you see any oil leaks, tighten the turbo bolts a bit

good luck, this is the bare minimum. i ain't a mechanic, but i did this last night, so i know it's doable. hit me up if you run into weird errors.
