This is my version of the 1KZ-TE resistor mod. It has been working for me for over two years without any troubles and is one of the cheapest and easiest mods you can do, it cost me less than $15.
So you’ve just put a .5W 1.5kohm resistor in the grey plug and left it at that, and wired in a potentiometer for the brown plug ? So I would need to buy 1 resistor and 1 potentiometer ? Or is there a inline resistor wired into the brown plug aswell that I’m not seeing, I’m looking at doing the same on same setup truck, will do boost defender too run aroun 18psi.
Hello Aaron, 1st thanking you for the vid explaining the resistor mod in the timing and fuel, i have a 4runner with the 1kzte engine without the intercooler but i manage to implement the OEM one and now did the resistor mod in timing (Grey Plug) and it really makes a difference did a dyno with and without and the diference is about 10Hp and 45Nm and happy with that, now i wanna try the Resistor mod in the fuel (brown plug) hopefully i dont blow my engine but i have a question your Variable Resistor is 0 to 5Kohms its that safe to do offroad using the 5kohms all the time? what is the EGT to worry about? and the other question my original car is a non intercooler version but i implemented the OEM intercooler but didnt not change the ECU.... is the ECU different? thanks in advance
I use a red arc egt gauge. the good thing about a variable resistor is you can turn the fuel down for on highway use.on highway use my get gets to 750 degrees and in the bush it spikes to 1200 but only for a few seconds. personally I wouldn't worry about the ECU it doesn't make much difference.another thing you could do is put a intake air temperature sensor after the intercooler just to monitor intake air temp
I've tried to do this with the resistor in the plug but didn't work so might try the variable one as have a few sitting in garage, I done the timing one and added a lil more power but want the real good power as its running 14psi atm
You will be happy with the variable resistor it works well do you have an EGT gauge with a warning system on it. I am running 25 PSI boost my next video is about how I am running the boost system in my truck 👍
@@AAELMIGER yup I have a egt gauge and that would be cool but id even be happy at 18 psi as above that it just blows hot air into the motor supposably.
The standard value is 0.38 there is quite a few different standard values. I have a 10k ohm variable resista in my truck but when it gets to 5K The ECU cuts the fuel back to an idle mixture
I can make a quick TikTok video of it tomorrow and post it on TikTok and my Instagram. My TikTok and Instagram is Mega mechanical I will try and put a link up on here shortly
You can do that and it will work. I wanted mine to be a little bit more trouble free I have got a heap of spare fuel pumps so I used a standard resistor and cut the back off it soldered in a new resistor and sealed it up with RTV silicon.
I used a 1.5 k ohms resistor for my timing which is the grey correction resistor on the pump . And a variable resistor for the fuel which runs from 0 ohms through to 5K ohms
Hey mate
Really appreciate the 1kz content and I’m looking forward to your sas video

yes over 18 PSI will pump a lot of hot air but you can overcome that with an intercooler @@4x4MadnessNZ
@@AAELMIGER yup im doing 27-28psi now with front mount and a ton of extra stuff
@@4x4MadnessNZawesome you will love it
Kia Ora bro. Nice truck! Do you know if this resistor mod works ok on an auto? Cheers fella
Yes it should I can't see any reason why it would not work
Cheers bro just a small question was the standard value 3.8 or .38? and which direction brings on more fuel? cheers
The standard value is 0.38 there is quite a few different standard values. I have a 10k ohm variable resista in my truck but when it gets to 5K The ECU cuts the fuel back to an idle mixture
Beast!
Hey bro on ur boost gauge do u show vacuum at idle I always thought diesel stay at 0 on idle
typically you will not see vacuum at idle
What mod did you do to be able to run 25psi without having boost cut problem bro?

@@AAELMIGER please do 😊 i just recently did a 1kz swap on my lj78. Currently having boost cut hitting 14 psi 😔
what type of variable resistor did you use?
The part number is RP3608. I purchased the resistor from jaycar
I have one with mecanical pump....i live in panama canal....you think that the intercooller gain some hp....
Adding an intercooler is beneficial in so many ways, Yes you can pick up some horsepower but you will also gain reliability.
Hey mate, does the variable resistor need to be logarithmic or can it be linear? Jaycar is all out of logarithmic ones at the moment. Cheers
When you do the timing one do you then just tape over and let it hang?
You can do that and it will work. I wanted mine to be a little bit more trouble free I have got a heap of spare fuel pumps so I used a standard resistor and cut the back off it soldered in a new resistor and sealed it up with RTV silicon.
Have you installed an intercooler on the no intercooler 1kz ?
Yes I have installed an intercooler the video will be up shortly
Hey mate. Did you increase the boost at all or leave factory?
I am running 25 PSI boost on the standard turbo check out my other videos 👍👍
cant see any other vids bro or have u taken them down
Why 1.5 for timing?
good question that just seems to be what everyone else is using. one day I'll buy a dyno and do some more testing
what wats are the resistors?0.5
1
1.5
2?
thanks
I used a 1.5 k ohms resistor for my timing which is the grey correction resistor on the pump . And a variable resistor for the fuel which runs from 0 ohms through to 5K ohms
@@AAELMIGER thanks, the only thing is that besides having the value of 1.5 omhs there is different watts resistors
I misread the question both resistors i used were 0.5 watts
