Hi,
I am a Canadian ex-pat living in Nicaragua, and own a 2007 LX470 that has been imported here from the UAE. I've owned the truck for just over 1 year, and it has unfortunately spent less than 1/2 that time running. I have a number of questions regarding the engine and wiring harness, and was hoping that someone might be able to help me figure out where to get the most accurate information.
The vehicle had suffered a catastrophic over-heating event due to some un-repaired and hidden damage. Both heads and the block were beyond repair, and the mechanic I was working with confirmed that my only option was to replace the engine. I have purchased and imported a rebuilt 2UZFE-VVTI, but when my mechanic went to install it found that the old heads were not VVTI. This strikes me as odd, since my understanding was that the 2007 LX470 would have only been available with a VVTI engine.
I have found very little information on people swapping to VVTI, but had seen one comment stating that it would likely require a swap of both the ECM and harness. This makes sense, as the existing ECM would likely not be setup to control the VVTI, and the harness would not be have the necessary plugs.
The VIN I have in my records is JTJHT00W074025561. When I search the VIN, the engine detail doesn't come back saying VVTI, but I'm not sure that it would/should. I will be going to look at the truck myself next week hopefully, and will retrieve the numbers from the chassis and the engine, confirm that they match, but was hoping that someone might be able to confirm what engine/ECM/harness would have originally come with the truck, and if not the VVTI, what I would need to make my VVTI engine work with this vehicle. Part of me optimistically suspects that possibly the heads were swapped at some point, and that maybe the EMC is correct and someone just removed the VVTI wiring in an effort to 'make it work' when it was exported from the UAE. I can't be certain of anything right now unfortunately.
