1KD-FTV Ratio Bracket, MCR
1:1 Pump Drive | HP3 (2 Rotor) or HP4 (3 Rotor) | Hilux N70, Prado 120 and 150
The factory 1KD drives its injection pump at roughly half crank speed. The MCR ratio bracket mounts the pump on a belt driven bracket at 1:1, so the pump turns at crank speed and makes twice the strokes per engine revolution. It is the answer when the pump is the limit: big nozzles, high commanded rail pressure, and a stroker pump that still runs out under load.
Fitment
| Vehicle | Engine | Variant |
|---|---|---|
| Toyota Hilux N70, Prado 120, Prado 150 | 1KD-FTV with the standard 2 rotor HP3 pump | HP3 (Standard / 2 Rotor) |
| Toyota Hilux N70, Prado 120, Prado 150 | 1KD-FTV converted to a 3 rotor HP4 (1VD style) pump | HP4 (3 Rotor) |
Quick check: check which pump you are running before you order. A stock 1KD is HP3. If you have done the HP4 conversion, or are doing it with this bracket, select HP4. The HP4 pump itself is not included.
Converting to HP4? See the HP4 / 1KD injector pump upgrade kit.

What Build Is This For?
A stroker pump is the first step when a tuned 1KD runs out of fuel supply. See the 1KD stroker pump. When that still cannot hold rail pressure under load, the next step is pump speed, which is this bracket. It pairs with +50 nozzles and above, and on an early 2005 to 08/2006 rail with the 1KD rail blank. Tell us your build and we will confirm whether you need it.
Fitting Notes
- No drilling or modification to the block or mounting. The bracket installs directly.
- Expect to extend or relocate the pump wiring.
- Rigid fuel pipework will need careful re-shaping or new lines.
- Check belt alignment, tension and clearance before start-up.
- Tune required to use the extra pump capacity safely. Workshop installation recommended.

Frequently Asked Questions
Q: Will this bracket increase fuel volume on its own?
A: No. It doubles the pump's speed, which raises what the pump can supply. The tune, injectors, rail and lines decide how much of that gets used.
Q: Which variant do I need, HP3 or HP4?
A: A stock 1KD runs a 2 rotor HP3 pump. If you have converted to a 3 rotor HP4 (1VD style) pump, select the HP4 bracket. Check your pump before ordering.
Q: Is this a bolt-on?
A: The bracket mounts without drilling or modifying the block, but expect to extend the pump wiring and re-shape the rigid fuel pipework. Check belt alignment, tension and clearance before start-up. Workshop job.
Q: Is the pump included?
A: No. Bracket and mounting hardware only. Your existing HP3, or an HP4 pump for the HP4 variant.
Q: Is this road legal?
A: Intended for off-road and competition use where permitted. Check local regulations.
