I should have said 30-40 lbs over all. If you relocate the battery in the rear, some of the weight gain will be in the nose.
If you are tubby like me, that is not bad.

If you are talking about going to the jabiru 3300, you will need:
new engine mount
electric fuel pump
reworked control cables
new cowling with reworked cooling
starter solenoid
starter button added to panel
location for voltage regulator
new prop
custom made cooling plenum for dowdraft or baffling for updraft
You will potentially need:
a custom exhaust made (if you don't like the stock jabiru pusher exhaust)
relocation of the battery from the nose to the firewall (Oddesey 625 recommended by my dealer)
The engine weighs 175 lbs, dry, without the muffler, but including electric start and 20 amp alternator and mechanical fuel pump, hoses and attachment hardware.
Electric Fuel pump, 2.5 lbs., extra wiring, 2 lbs., addtional pelunum weight 2 lbs. solenoid, 1 lb.for a total of 182.5 lbs.
The smallest o-235 is listed by Lycoming at 243 lbs. Of course that is with a starter and a large alternator, but even if you figure you started without a starter and a with very small alternator then I am adding electric start, picking up 5 horsepower, and losing about 30-40 lbs in the rear.
The weight savings is less from an O-200, but the horsepower gain is larger.

wolf,
I am in the process of the same thing. Call me if you want information on the engine mount, etc.

I am currently installing a Jabiru 3300 on my Varieze. There is one other in Australia in progress and one in France flying.
The engine mount took a little time, and the lighter weight has required relocation of the battery. I am currently working out the cooling and building the cowling.
If interested email me at Mwilli7119@aol.com and we'll talk about it.

Gilbert I didn't realize you are in France. There is a Varieze in France with a 3300. He is a nice guy and I sure would be willing to talk to you. He changed from an O-200 and is using an adjustable prop so his weight difference was not much.
I think Bill James has an O-290 on his highly modified Varieze but I know of no O-320s or O-360s out there. I am not sure the weight gain would be worth the added horses. But do not take my word for it.
The French Varieze owner with a Jab 3300 is:
