The bolt patterns between the 4GR's SCV plate and the 2GR's port injector manifold are different, as are the footprints of the different plastic intake manifolds.
Also, there's a dramatic difference between 12 and 6 injector heads at the intake ports...the 2GR has 6 holes, the 4GR has 6 pairs of holes, since the 4GR's valves are independent of each other until the SCV butterflies and the 2GR's intake ports are siamesed.

I offer ecu remap for VSC and dash compatibility: 3UZ 6 speed auto into 2006-2012 IS250 , and 2GR GRS18x/19x/IS350 into IS250 . Other possible things are m/t conversion, speed limit off, supercharger tune (stock internals and up to 0.35 bar of boost).
Service is available in Russia, USA, UK and New Zealand

Then there would be no need to swap the topend of the 4GR to the 2GR bottom. And what is the price on this and since I'm from Finland I'd need to send the ecu to you?

What would be the price on each option? I'm on a budget for this swap and looking to do it for under 5k€.

Swap!
Looking to do swap on my 2009 is250 m/t. What swaps are ready possible as far as remapping/ecu kits and trans adapters. I’ve done some research and found 3uz has been done but only in automatics. I’ve recently put a stage 2 clutch and light weight flywheels from spec in and kaaz 2way lsd on the way. I’m using this car for seat time. So it’s a work in progress but I’m looking to keep the ra62 till I can’t. So need options to be compatible obviously. Any help is appreciated
Also, I would like the option to be able to handle a little build worthy down the road.

I did speak with that guy in Australia, yeah, though he didn't provide me with any more information than I already had to be honest. They also decided to go with the Fidanza flywheel, but I've decided to keep the dual-mass flywheel with a rubber-dampened clutch disc. I feel it will help dampen the driveline more than just using a sprung disc, and I've never been a big fan of aluminum flywheels. Perhaps if someone made a different flywheel I would consider it, but alas, the RA62 does not have much aftermarket support unfortunately.
I hope to have (what I assume to be) the first LHD IS350 6MT.
