1. The K20 is the new engine of choice for
Honda, powering everything from the Civic to the
CRV. We start by disassembling the stock airbox.
2. The K20 is uncorked with a K&N short ram
intake. The Piranha nozzle will be tapped into.
3. The intake fits snugly on the
throttle body. With a full 3" plenum, this
intake swallows vastly more air than the stock
airbox.
4. The owner of the Civic opted for a throttle
activated switch instead of the more popular
push button. The systems comes on only at full
throttle and cuts off automatically when the
pedal is released.
5. The Civic has three switch panels ready for
just such an application.
6. Adding some visual flair is the optional
aircraft style covered switch.
7. Here we see the microswitch bolted behind the
pedal. Stepping on the pedal closes the circuit
spraying the nitrous and fuel.
8. The two solenoids are mounted close together
and all the lines are attached.
9. The battery bracket provides a convenient
place to mount the bracket holding the
solenoids.
10. We drill the intake for the Piranha Nozzle.
11. And screw in the bung where the nozzle will
go.
12. Here is the attached nozzle.
13. All newer cars feature a solid plastic fuel
line encased in rubber. We splice this and put a
T fitting for the fuel supply to the solenoid.
14. We run the wires and nitrous lines through
the driver side firewall.
15. Black car equals black intake at the owner's
request. Here is the completed nitrous install.
16. The tank was mounted near the back of the
trunk so that maximum trunk space is still
available for things like golf clubs.
