Hi, I have a 06 is250 6MT And currently have the is350 Long block, Im going to start the Swap in the future. but im kinda confused about the VDIM system for the is350, do I absolutely need it to swap to the 2gr?

Hey Jeff
I might be getting my hands on the flywheel that you have there.
I was wondering if you would be willing to share all the parts that you purchased for the clutch setup as I will need to purchase them.

THank you Jeff for all the report here. It 2024 and I am thinking to do the same to convert my is250 2.5 to a 3.5 auto. But I will keep mine automatic. Will I need to change the dash or ECU. What are the ads ons apart from the engine and fuel lines. As you mentioned that we are able to use the same transmission as the one from the IS250. I highly concerned about how difficult the electronics and wire part will be. As I want to start and finish the project as quick as possible. Like on a week once I have all the parts

3.5 ecu needs remap if you want to retain VSC and TRC
There are other possible upgrades
Wiring wise, required changes are few but are important, they include at least wiring of ecu pin E2 to chassis, also pins TAM, SPD, CCS

And what is the reason?
As I am only swapping the engine (no need for transmission adaptation because I am using the original automatic of the is250). I found a supplier that is selling the 3.5 engine with an ECU as the supplier mentioned:
"All engines are well tested and complete with all accessories (steering pump, kick starter, alternator ECU, and AC compressor)"
If this is true, then a lot of hassle would be voided, apart from taxes and delivery costs to Europe.
What do you mean " at least wiring of ecu pin E2 to chassis, also pins TAM, SPD, CCS"
By the way thank you for the first reply...

I found something interesting: The Toyota Mark X GRMN uses the RA60 (possibly modified). It has the same engine, 2GR-FSE. Here is the transmission: https://www.amayama.com/en/genuine-c...5/chassis/3301
And here are other parts like clutch kit etc: https://www.amayama.com/en/genuine-c.../80855/chassis.
Might be interesting for those looking to swap.

I mentioned ECU pins how they are mentioned in wiring diagram
When installing native 2GR ecu, you will lose at least VSC/TRC because variant coding will not match. This can be fixed by ecu reflash
You can of course keep 2.5 ecu to control 3.5 engine, but it will not control 6 out of 12 injectors, and all running modes except wide open throttle will be messy (however you will retail VSC without any reprogramming)
And like the hint above, new thread can be started

Yeah. I will start a new thread soon, once I get the engine. I got some good deals. I had to postpone the project because I went on holidays and bought a condo on this last minute(tired of rent). You know, there aren't is350 in Europe. Specially in Ireland. That is one of the reasons for the swap. It's cheaper for me to swap the engine than importing an is350 fom Japan
I will do most of the whole project by myself. Kind of self learning. The only outsourcing will be the ECU. I will also document everything on the thread.
I will add the link here for people looking for exchanging knowledge and tips.
Thanks for the help.

Regarding VSC/TCS, this is primarily a problem on 2006-2008 IS250s without VDIM. On 2009+ both the IS250 and IS350 share the same VDIM system. There are obviously still ECU pinout differences between the two.

I am curious on the remap for the VDIM delete one the 2grfse ECU it is the only issues I have with my swap and would like to resolve it. I did purchased the entire setup to add VDIM but I would prefer to code it out. If you could tell me a little more about this it would be much appreciated.
