There was a dilemma when i was choosing N/A or turbo path, but after figured out the weight & power ratio that i want to match to the E46, 1JZGTE is better and i was right. Some 1UZ swapped E46 owners complaint that the nose of their cars gotten much heavier and makes understeering very profound. 1UZFE weights 250 kgs and 1JZGTE weights 204 kg while the original BMW M43 weighted at 138kg and M54B25 engine weights at 130kg. I have to shift the 1jzgte position slightly backward and lower to get the balance the car weight. With 1UZ, don't think this is possible as the engine is tall with 90' design and not to mention its weight. Fortunately all the swap is done without anything done to the body and i can taste the smoothness of inline6 and its turbo powahhhhh when on boost. Its intoxicating.

The 1jz weighs 204kg with or without the turbo and inter cooler?
Yeah boost is intoxicating but somehow on average I probably drive as slow if not slower in my Evo than my other 2 NA cars! Lol.
don't think the UZ would fit. Some friends of mine commented that it's a wide engine although short. Wide is never gonna fit in a 46 engine bay.Makes me wonder what would my E46 be if i chose the 4.0 1UZFE V8 instead of 1JZGTE VVTI, with few mods can the E46 drag like the E92 M3.
And you're better off with a M62 or S62 if you wanna do v8. At least BMW engines will fit there properly....
First of all research how much power and torque the gearbox can handle. Then find out how much your current engine delivers. Then from there you can estimate how much you can mod.
Not included, purely engine weight. Hahaha that's what i'm impressed with 1JZ, i boost all day long and still return me with kinda good FC. On average, RM100 on RON95 can get me somewhere 360 km or 380 km.
There are plenty of E46 with 1UZFE, domestically and internationally. However, the engine bay is fully occupied that makes modifications very troublesome. Russians like to fit this engine into their E46, locally wise, i went to this Lee's Garage in Shah Alam, they have done a couple of 1UZ swapped E46 in the past with great success.
For modifications, 1JZ will benefit more as more working room. For stock standard comfort, 1UZFE will be good enough. The later version of 1UZFE packs 320hp N/A. Some simple IHE, ignition and ECU should get another 30 hp easily.

I'm impressed you're running on RON95! And how can you boost and have good FC?? When I was doing it, boosting too much meant 100km shaved off my FC
Then if all included still about 250 kg also.
Wah that's the same as mine OFF boost! Last week measurement only got me 7.7km/litre testing on 95 with Bardhal octane booster, granted I went thru quite a lot traffic jams. Seems like this mixture gives me a bit better FC than pure 97.
The engine has no problem running on RON95, no vibration and no knocking even at 6.5k high rev.
I think thanks to the final drive, when i am cruising at 120km/h or below, my RPM is about 2.5-2.7k. Now i am gonna figure out how to rid of the droning sound !
Interesting, can i find this in ACE Hardware ? I think in time it is still better to have higher octane for high performance engine. I also noticed engine will run colder when on RON97 or RON100.
Oh tall gearing, no wonder!
I bought from Lazada/Shoppee. Supposedly can increase ron by as much as 3 numbers (up to 30 points), so theoretically similar to 97-98? So far I tested no knocking even on full boost at red line.
