Since my car was originally an M/T it didn't cost as much as sourcing a whole M/T kit.
Bought a complete IS350 wrecked car for fairly cheap 4k and did the whole process by ourselves with my brother and I. Car runs a fidanza flywheel with the spec stage 2. Although it's holding up now I may go for a higher spec clutch, maybe a 3.
Great work my friend.I was waiting for someone to do this first.Does your 250 have VDIM.What did you do with that because the promblem was the VDIM.SARD in Japan who did this first install a ecu to trick the OEM ecu so that the engine can run with the manual transmittion.Which ecu did you use
?Sorry for the questions but when i finish my conversion this will be my finall mode
350 engine feels great with the tranny almost as if the box was developed for the engine.
I'm afraid nothing is displayed on the gear selection, it just says current gear.
Car hasn't been dyno'd yet but with the mods, manual tranny and an A/F ratio tune from novel I'm hoping to pull somewhere around the 230-240rwkw and high 12s in the 1/4 mile. Though the car still has an open diff and it sucks but thanks to Jeff Lange, who gave me a peace of mind in adding the IS300 torsen LSD to the car, I will be adding an LSD in next week.
Stay tuned for more videos which I will be posting up this weekend.
So its really just an engine conversion. NOT a transmission conversion since the car is an original IS250 that came with the M/T right? Im not to worried about the technical stuff on getting the engine and transmission in the car since the 2gr and 4gr are the same layout and uses similar transmissions. Thats a no brainer and everyone knew that its a near direct install
Im more interested in the wiring it up and how you got that to work with everything with NO CEL. Did you just pull in the whole IS350 wiring harness?
My biggest concern with doing this swap has always been what ECU to run. If I run an A/T ECU, it will set off a bunch of codes for not seeing/controlling the A/T. SARD can flash a Japanese ECU, but will it work properly in a North American car (may not be able to program the VIN properly/different key frequencies/etc.), SARD has said they would try to flash a North American IS350 ECU to M/T, but they've never done it, it's an awful expensive risk.
I will keep thinking about things in my head, haha.

Could you please share more info about the swap? Especially about the electronics, harness & ECU connections and mods.
I remember looking into this swap and reading about the transmission not aligning with the 350 engine, was there a lot of custom work to make that work? If not…we need a how to/ DIY for this!
