This is a full, completely bolt-on, additively manufactured kit that includes every mechanical component required to put high-quality 03-06 Honda CBR600RR Kehin throttle bodies onto a 1986-91 Naturally aspirated Mazda RX-7 (or any other vehicle that has an 86-91 6-Port 13b). With its angled construction it can also fit in very cramped engine bays without having hood clearance issues.
This kit has been tested to fit on S1, S2, S3, S4, and S5 RX7 chassis with the correct lower intake manifold (from 1986-88 S4 RX-7).
As for power increases, you can expect a broad increase in power and torque, particularly past 4000 rpm. Power numbers on a factory port engine should be near 180+ hp at the crank with a healthy engine
Notice! This Manifold ONLY bolts to an 89-91 NA lower intake manifold, 86-88 has a different bolt pattern. If you are using an 86-88 LIM use our 86-88 ITB kit!
Includes:
- Adapter Manifold (throttle body to S5 lower intake manifold)
- Throttle correction adapter
- Throttle cable with firewall adapter
- (4) 50mm open trumpets with retainers
You will Need:
- Standalone ECU and subsequent wire harness
- 03-06 CBR600RR throttle bodies (readily available used with low mileage)

- Injectors suitable for your application
