The picture is of the EFI installation in the landrover (wiring is still yet to be tidied up and we’re looking for a cheap source of 90mm plastic pipe to run the inlet of the airbox back into the cab avoid getting water into the intake).
A couple of clearance problems, a notch is needed in the footwell to clear the inlet manifold and the standard extractors won’t clear the chassis rail.
I modified the extractors and re-routed the primary pipes, but next time I’d probably just put on a carb version of the exhaust manifold in the landrover. This has really transformed the holden motor making it much easier to start, more powerful and most importantly, the engine won’t stop while on a sidling or incline.
This site is really helpful .. http://oldholdens.com/tech/eficonversion/index.php we didn’t do everything suggested but it is quite detailed. This site is also useful .. http://www.ostat.com/dave/VKEFI_Page1.html it has the wiring diagrams as well and describes a VK carby to VK EFI conversion.
Here is a quick summary of the EFI install in the Landrover (Holden 202 head)…
Parts needed ..
- Later model cylinder head blue/black 12 port
- EFI inlet manifold with injectors etc
- Throttle body with TPSensor
- Temperature sensor
- EFI distributor
- Air Flow meter
- Coil
- ECU (Computer) (standard although an aftermarket one can be used)
- EFI fuel pump (from a VK or VL commodore)
- Miscellaneous fuel lines, wires, relays etc.
Some things to think about :
- The loom has a lot more wires than you need, it takes a little figuring out which ones go where and which ones aren’t required.If I was putting into a VK or earlier holden, I wouldn’t try to integrate with the existing loom, I’d keep the EFI loom separate.
- A return fuel line is required back to the petrol tank. Most high performance installations use a surge tank to ensure that the EFI pump won’t run out of fuel which requires a low pressure lifting pump and the EFI one. All we did is simply add an extra outlet to the fuel tank. Not having a surge tank hasn’t been a problem for the Landrover or for the Patrol.
- Don’t forget high pressure fuel line is required from the EFI pump to the fuel rail.
- You will need to adapt the throttle linkage, this just requires a bit of ingenuity.
- Mount the computer somewhere where it won’t get wet.
- The standard system uses a control relay for the fuel pump which basically won’t run the pump if the engine is not working (takes a feed from the distributor). Many conversions don’t use this , but I plan to add one when I tidy up the wiring. Later model ECU’s control the fuel pump relay and switch the pump off if the motor isn’t started within a certain period of time .. and ..so don’t use these control relays.
Our next task is to cut out unused wires from the loom, mount the ECU permanently in the cab, add the control relay and waterproof the inlet system.
