Alloytec 3.6 or SIDI 3.0???

[brian416]

hey guys i want to buy a holden VE commodore omega, but i dont know which one is better, with Alloytec 3.6/4 speed auto gearbox or SIDI 3.0/6 speed sport auto??? power,acceleration, shift gears...
i think the 6 speed sport auto gearbox is better than the 4 speed auto one, but how much different between these two? and what about the engine. anyone can help???

Depends on price range etc I guess

We have a 4sp dual fuel MY10 berlina and don't seem to miss the extra gears(did 40000km in a year), some do complain about the 3l lack of torque. go a 3.6l 6spd in you can afford

3.6 all the way. My VE is now 5.5 years old with 4 speed box, and it's fine. And the car has heaps of power when and if needed.

Have had a fair bit to do with commodore fleets over the years. The 3L SIDI (LF1 / LFW) is far superior to the earlier low output 3.6 (LY7) and puts out more power 190 KW for 3.0 and 175 KW for 3.6. Fuel economy is also vastly superior. 6 speed auto much smoother than 4 speed.

Go for the 3.6 over the 3.0 , feels more powerful in my opinion , more torque as well , if you can , go for a SV6 or Calais , in the VE they are more powerful

Never owned a 3L but work cars avg 13L, our amf SS is on 12L, real world econy of the 3l isn't good from what I hear. If your towing or live around hills etc get a 3.6

yep , can concur with that , some of the our 3.0 L general duties Omegas use more fuel than the 3.6 Omegas and SV6 ones , it very much depends on how you use them , I don't think I'd want to be towing with a 3.0 L one , it's a heavy car , with a busy little engine , even the extra cogs on the transmission cant really help it .

Are you serious! My experience is about 9 average for the 3L Omega (7.5 -8 highway) and about 12 average for the 3.6 Omega. As the OP has mentioned only Omegas I presume we are all comparing apples with apples.

very much depends on how they're driven , if I drive my VZ SV6 economically I have seen it return 9.5-10 average highway .

I've got a vz sv6 ute with 3:46 vy Ss diff, full pacemaker exhaust system, mace cai and manifold spacers, excedy HD clutch, 19s and ssl front and sl rear, ss hardcover, subs and amp, it's also manual and CHP tuned... but I can get it down to 8L per 100k on freeway in 6th sitting at about 2300 rpm so it all would depend on how it's driven.. If I have some fun and give it a hard time she will chew the juice worst then a old dirty 5L lol over 20L per 100k so yeah to any1 looking to buy and vz ve take it for a good drive, stop start, 3way and give it a boot full so u know wat ur getting into fuel and power wise hope this helps.. Ps mine revs till 7k now to and pulled 200rwhp! In 4th with 20s and a 36degre + day
