I reside in New Zealand and own a 2022 hijet dump truck. It is my daily driver .
Obviously, like the thousands out there, I see the potential to upgrade and would like some good advice.
I’m exploring the possibility of swapping the standard kfve motor with a kfdet ( hijet van) motor to improve the to torque and highway driving ability.
So, I’d like to know if anyone has done such a conversion and would like to know what is involved .
Specifically , does it need an ecu and fuel pump change. Will I be able to use the existing harness. If I replace the ecu will it be a simple plug into my existing harness and will all my standard functions be maintained. I’m no tech fundi and don’t quite know whether the ecu influences the standard safety features e.g. lane assist and collision avoidance.
Any help would be greatly appreciated. Any hardware changes I should be able to take care of
Welcome to the forum I reckon you would need to swap the ecu and wiring loom in the least as there would be a few extra sensors and ecu functions relating to boost. may be best to get one that has been written off and do a complete swap as you may possibly need extra things also.
Thanks for the input. I’ve noticed that some of the engines advertised on Beforward come completel with wiring looms and ecu. I’ll continue to explore the options.
Another option I’m willing to look at is a 1000cc k - series engine but I’ll need to find out whether the conversion would require too many alterations
Welcome to the forum.
I have wondered about the kf-det swap.
Would the kr-fe would make an interesting swap but I’m sure the sump and oil pick up would have to be changed over, as well as the ecu and loom.
I am a HiJet enthusiast but unfortunately not an owner.
Check out youtube for a Midget Engine swap where the boys from Mighty Car Mods changeout a 660cc with Daihatsu’s 1.0L motor from a Mira. Good swap info there.
Hello Seanjet, I’m a newbie also. I also own a hijet but an earlier model. Due to the laws here in the US, you’ll mostly see models at least 25 years old. I to am looking at the KF-DET swap but of course I don’t have all the modern bells and whistles on my hijet you have so I’m hoping my swap will work out a little easier. Maybe that’ll be my downfall though . I’ve found this site to be packed full of great information and very knowledgeable people but unfortunately I haven’t found to many folks that deal with hijets… I would like to stay connected with you so hopefully we can help each other and share any found information about our swaps. I’m trying to go from an EF-NS to a KF-DET. I think if I can source the engine ECU and harness. I may be ok. I can use an aftermarket fuel pump and regulator. If we don’t find anyone with experience on these swaps I guess we’ll have to be pioneers!
