total around 625lbs+/-
Im also using the 3SGTE motor (series 2) in my build and did weight it on commercial electronic scale and here are the figures for complete installation with gearbox;

1. Engine - complete block, top and sump unit = 105 kg (235lbs)
2. CT26 Turbo unit complete = 12.4 kg (28lbs)
3. Complete inlet manifold and TB ex factory = 6.8 kg (15lbs)
4. Flywheel = 6.9 kg (15lbs)
5. W58 Toyota gearbox = 35 kg (78lbs)
6. Bellhousing = 4.4 kg (10lbs)
7. Exhaust manifold (tubular) est. to be made = ~7 kg (15lbs)
--------------------
Total weight 177.5 kg (398lbs)

Only the starter and alternator weights should be added.

The 4AGE 20 valve motor with gearbox weigh in at 157kg. Add the 15kg difference 7ishNZ mentioned and the sum is now 172kg. Close enough.
That said, the ex factory inlet manifold get replaced by a custom plenum unit that is low and compact and will weigh considerably less than the long ram std unit.

Interesting; for the 15kg weight difference between the 4AGE (115 kw) and 3SGTE (185 kw) the difference in factory std power is about 70kw (94hp) not to mention the big torque and shove of a turbo.
It is also a well known fact that the Japanese kw rating (115kw) for the blacktop 4 AGE is very optimistic and about 105kw max is more to the truth measured against "normal" units....
Then again, more power is easily available from the 3SGTE by just a turn or two on the waste gate valve from the std 9psi factory setting. Many run between 12 - 17psi for some wicked performance.

As for shipping weight: if complete motor is bought it will have the inter-cooler on-board, so the aircon pump, power steering pump and some heavy cast iron monstrosity that acts as exhaust (about 20kg) manifold. But still the weight should be quite less than mentioned.

Finally, I personally believe the 3SGTE is a better bet than a Rover V8. It will outperform is easily on any given day in std form, more easily to tweak (boost) with minimum effort and nothing beats that turbo push when its on the boil As for lag - without boost it is still a 2 liter engine with 8.8 to 1 compression ration in a 600kg (or less) car and still be decently fast up to about 2700rpm when big horses are awakened for blistering pace.
And it use much less fuel than the V8 driven moderately
