Hey guys, just out of curiosity. Is it possible to sway the is350 engine(2GR-FSE) into a is300? If so has anyone done it yet? Also does the is350 engine weigh more than the is300 egine? or does it weigh less?

I highly doubt that anyone has done that swap but anything is possible. It would take a lot of time and money to be the first one to try it that's for sure. I am not sure about the weight differences.....

I thought about doing it to one of our 300s, but none of the guys shared my enthusiasm.

What would be the point of that? If you want a head-turner swap
consider the 4.3L V8. A member did this swap you can find a link to
his whole process in the sportcross forum.

im pretty sure its heavier the 2gR.

probably would not fit.... extensive modification are needed.

BUT if you think about it.... that one Member who drived a Yellow Is300 SportCross Fit in a Gs Engine....
And that was, just WOW.

where are you gonna find the engine in the first place.. you cant walk to the junk yard or Super Auto Bacs :)

my two cents

I think it'll be lighter than the iron block 2jzge. Remember, aluminum is lighter than iron.

The weight distribution will be improved with v6. It's lighter, more compact than inline six. CG of the engine will farther move to the center of the car, improving dynamics and handling.

Making engine mounts is not that hard but it's the eletronics that'll kill you unless you use a standalone unit to control direct inject and all the good stuffs.

We had a couple spare 350 motors here at Team Lexus and the idea was to make two insane drift cars.

I'm not planning to do this to my car or anything. I was just wondering if it has been done yet. The is350 engine just seems like a real nice engine to put into a is300. Maybe later on someone might attemp this?

13-year bump, anyone know if there is someone out there that has offered any support for this?

I see the engines are priced fairly well now.
It would be nice to have a 3.5L OEM Toyota engine making 300whp~, plus the weight savings of 100lbs which definitely would benefit handling.

Maybe I'm being optimistic, but the cost of custom mounts, wiring, and junkyard engine would be about same price as NA-T 2jz (GTE internals, turbo, intercooler, injectors, ECU, etc.).

Now if the engine is too tall to fit, then that changes the story.

A 1UZ/3UZ is a better choice in most ways. The early ones talk MX bus like the IS meaning you don't have to mess with canbus. Both are automatic only. The UZ's are a relatively proven swap. You don't need custom engine or transmission mounts. They fit between the shock towers. It's a bit tight but they fit. The V8's are even easier to work on than the 2JZ. I have one in my car. It even passes emissions testing. Another benefit is that Lexus didn't include the VIN in the OBD2 dump till later than 01. It means if you use the same year V8 ECU you don't have to worry about the state flagging mis-matched VIN's.

If I was doing another swap, I'd probably do LS over any lexus engine. Smaller lighter, more powerful and readily available manual transmissions. A big plus is that the GM ECU can be reflashed to match your setup.

I also think the 1UZ or 3UZ is a better idea than the 2GR, not that I have any experience with those engines. I do have experience with a GR engine in my 06' 4runner (4.0L 1GR-FE) and it has no where near the refinement (or sound) of a I6 like the 2JZ-GE in my 02' IS300. I've read that the 1UZ was one of the best engines in the world when it was developed, with the refinement on par with the likes of luxury manufacturers.

Also, another funny tidbit of info I've recently seen on FB and IG: A guy in Russia swapping out the GR engines for 3UZ-FE's into 2nd/3rd gen IS's.

I'll bet they fit better in the 2gen's than in the first. The 1UZ fit is OK but nothing to write home about. The 2gen's came with v6's so they're likely wider at the shock tower than the IS.

Interesting, I'll keep my options open for now. Just want a little more pep than what bolt-ons do, but forums suggest it's a waste of $$.
