FUEL UPGRADE KIT
WRX STI
WRX STI VAB
Code No. 14007-AF003
Large capacity injector and fuel pump in one fuel upgrade package.
【Features】
- Designed with the latest generation BOSCH Top Feed type fuel injector. All injectors have been passed the spray test and similar performance injectors are picked up and packaged in one kit for each car.
- Improved injector performance results in a shorter injector dead time. (1350μsec => 900μsec at Voltage 14V and Fuel Pressure 300kPa)
- O-rings(2-pieces) and spacer(back-up ring) have been added to the fuel line connector for improving sealing.
- Stock harness connector converter is included.
- Includes same fuel pump in our previous fuel upgrade kit. Replacing connector and small modification of fuel case are necessary when installing to GRB/GVB. (same as previous kit)
Sealing of fuel line connector was improved
【Performance】
Comparison of fuel pressure and injector capacity (capacity is a calculated value)
| Fuel Pressure (kPa) | 250 | 300 | 350 | 400 |
| Capacity (ml/min) | 595 | 650 | 700 | 750 |
Comparison of fuel pressure and injector volume (volume is not guaranteed)
| Fuel Pressure (kPa) | 300 | 350 | 400 | 450 | 500 | |
| Volume (L/h) | 12(V) | 210 | 195 | 180 | 165 | 150 |
| 14(V) | 260 | 245 | 230 | 215 | 200 | |
Comparison of voltage and injector dead volume (300kPa)
| Voltage (V) | 8 | 10 | 12 | 14 | 160 |
| Injector Dead Time (μ sec) | 2290 | 1560 | 1150 | 900 | 730 |
【Attention】
- Injector nozzle is conical type (1spray) which is different from our previous 2-Jet type products. Please do not use the same fuel setting data due to the difference of injector dead time and fuel injection condition.
