*SOLD OUT* Mazda RX7 FD HT12 Stage 1 Turbocharger Upgrades 1992-1998
*SOLD OUT* Parts available approximately July 2026! Updates are being made to improve aero so we will see improvements on response and averall output over the previous BNR products!!!
REQUIRES CORE - MUST READ INSTRUCTIONS
CORE INSTRUCTIONS
The Stage 1 HT12 turbochargers require a core upon build up. No Y pipe needed with the core. Since we reverted back to modified HT12’s there isn’t a need to extend it like we did on the older upgrades.
Here are all the details on the BNR Stage 1 HT12’s!
- GT28 Casting turbine wheel
- Left hand shaft nut
- high performance 360 degree, dynamic thrust assembly(dual feed)
- Dynamic, billet seal plate (less drag than stock carbon seal setup)
- BNR’s drop in Gen 2 Billet compressor wheel upgrade (requires no modification to the compressor housing and 15% more peak flow over stock cast compressor wheel)
- Dynamically balanced less than .5 gram/in2 as a rotating assembly
- O ring grooved bearing housing (eliminate the silicone mess that’s normal)
- Ported wastegate (30mm)
- Radius put on the secondary turbine inlet (cuts down on cracking)
- Upgraded Actuator assemblies which have 3 additional psi over stock 7 psi actuators. The additional spring pressure will help you generate more boost even with the OEM boost control solenoids.
