Toyota 5L to 1KZ TE Conversion Part 1 - Electric to Mechanical Pump Conversion 

Thanks Jake!! We are loving the support! Makes all the dramas worth it haha.

We are delighted that this series is helping people do the same thing. It was a nightmare trying to find out information for this conversion. If you have any questions at the end of the series please feel free to let us know!

@@lifeina4wd yeah there's surprisingly little information available. Cheers, will keep that in mind!

@@BWheels888 How did the swap go? Did you continue to use the gearbox for the 2L?

@@kayakfishingmalaysia244 Still in progress. I'm rebuilding an R151F to replace the G52 gearbox that is behind the 2L. The G52 would not last very long behind the 1KZ.

@@BWheels888so does the R151F gearbox bolt directly to the 1kz??

Thanks!

We’re stoked you found it helpful. Hmmm we thought the sump would fit… our 1KZ is out of a 90 series too. If you do the mounts the same as we did without lowering the engine at all it should all fit.

@@lifeina4wd Cheers'- I'll report back later about my progress on my channel I imagine. I have read from locals (Iceland) who have made this swap previously that there is interference between the 90 series oil pan and the front differential. We did get 4runner here with the 1KZ-T which shares the same suspension components, so I imagine that sump would interchange directly(along with strainer) to make it an OEM fit if necessary. I'll try it your way first anyway. The next problem I face is the gearbox, my LN165 comes with a W56 which is not suitable for the 1KZ-TE and the R151 with the front drive shaft on the right is rare, the Land Cruiser has it exiting on the left. Do you know if there are direct swap transfer boxes that fit the 90 series gearbox with the output on the right? - Again, thanks - greetings from Iceland!

Ok so we definitely had to do something with the transfer case and our gearbox when we changed but we actually swapped gearboxes a few years ago… Shane is having trouble remembering what he did at the moment but he’s going to think on it for you! He’ll take a look at ours for you too.

It just makes the conversion a lot easier as you don’t have to worry about hooking up the electrics to your dash (only if doing the same conversion as us, as in a mechanically driven car). Same goes for the throttle cable. You can also tune them a bit easier as mechanical pumps are easier to modify for more power. Hope that answered your question 😀

The disadvantages are it doesn’t have any fail dates for over fueling when under load. High egts that sort of thing. (Ask anyone with a TD42)

@@lifeina4wd Got it

No you can’t unfortunately it’s a different bolt pattern.

Hey I’m so sorry I thought we’d responded to this! Pretty sure this is answered in the comments below though.

Depends on which transfer case half you use then yes.

Hey, the question surrounding what gearbox has been asked a few times below 😄 All the info is there!

1kz match r151f gearbox, 5 L match is G52 gearbox

@@mitchelllau6691and the 1KZ gearbox can fit to the 5L engine with the custom bell housing 🙌🏻

@@lifeina4wdcustom bell housing. and 1kz flywheel fits directly on the custom housing ?

Hey bro - we’ve answered this in the previous comment 🙌🏻 you need an R151 gearbox

@@lifeina4wd thanks I greatly appreciate it

That’s not good to hear.

The benefit of mechanical is it is a simpler system with less electronics. Those early electric pumps are very basic so going to the mechanical pumps gives you more parameters to adjust when tuning which can give you more power. Yes it affects the fuel but not necessarily in a good way haha.

Thanks for your reply very useful 😊

Hey Danielle! Just confirming we’ve messaged you back on Insta 🙌🏻

It’s the mechanical pump from the 5L engine.

Hey Jack! Hope the information on Instagram that we discussed has helped!

So helpful thank you so much for replying

Tacomas are massive you could probably put something better/bigger than a 1KZ in it!

Hi Jorge, we are a little confused as to what your question is?

We do have an Intercooler, it’s already there.

Hey Fawez, we did have to muck around with timing a bit which we discuss in Part 2. If you give Part 2 a watch and then let us know if you have any further questions from there 😊

@@lifeina4wd thanks for the reply just watched the video couple questions so you adjusted the pump towards the engine block with out the injector lines in to get the little bit more adjustment and then screwed the lines on and did you adjust the fuel screw to get it started sorry for all the questions but I’m doing a similar conversion and just can’t find the answers on google Thanks

It needs to go as far as it can in the slots towards the engine block for the timing, then the pump will need to be rebuilt with a boost compensator to actually get any benefit out of it. You will usually have to give it a nearly full turn of fuel on the fuel screw. Reef Diesel in Mackay (if you’re in Aus) told us about a 5 degree timing plate which adjusts the sideways plunger which will give you extra timing at low revs. This can help with starting. However we haven’t done that. Sometimes it carries on a bit when it’s cold but is fine within 5 seconds so don’t worry about it. Hopefully this helps! We know what a nightmare it was with the lack of info on google so more than happy for more questions

We didn’t have to do any wiring as it was the original mechanical fuel pump from the car.

Probably, any engine can fit in any car if you’ve got the ability to make it fit haha.

Hey Lance! We’ve answered this question a few times in the comments below 😊 I’m not with Shane at the moment so if you’re able to take a ready through and let me know if your question still stands?

So you have to use an R151 gearbox for the 1KZ motor.

If you are doing the mechanical pump conversion you can delete all the extra wiring from the 1KZ. If you are trying to keep the electronic pump you will need to use the 1kz engine loom. Hope that helps! Let us know if you have any other questions.

Yes it does

Add a boost compensator and got to go max rotation towards the engine for the timing.

Hey mate, which pump did you use? Does the engine run alright? And have you had it tuned at all? It sounds like the pump is not set up right or the timing is out? If it’s not shifting gears properly that’s something to do with the gearbox.

No, the engine mounts are different. We do mention this at some stage during this video or the next.

@@lifeina4wdso on the both side do have modify the mount ?

It's manual

Yes 100% - we discuss that in this video series 😊

We don’t have a shop sorry

Hey! We are not professional mechanics and really only know about our cars engine etc. It might be best to get some advice from a professional mechanic! Good luck!

Hey Jed! Shaneo would be more than happy to have a chat with you. Do you have Instagram? We’ll pop you a DM on there with our contact details. Alternatively you can email us at lifeina4wd@gmail.con and we’ll email you back. 😁

Haha love the shade, although we do have to say, we do feel it would have more impact had it been grammatically correct. Insulting someone’s accent whilst using incorrect grammar is kind of a paradox. Thank you for engagement on our post though!
