thinking of putting induction kit on my 2.5 v6 elite is it worth it will i gain any performance change also having service new plugs oil ect thanks andy

[ozzycat]

bad idea the car will run better as standard somthing to do with air temp entering engine

[amba]

Total waste of money and effort IMHO.

Spend the money on giving it a full (proper )service using GM parts..change oil and filter and give those breathers a thorough clean.Thats the best improvement you can acheive.

Any form of forced induction - turbo- or super-  charger will probably end in tears as the bottom end won't take the strain.

Any change to the naturally aspirated set up will probably actually reduce the power, although it might change the noise.

Why do you think VX technicians spent many hours designing and building the intake to be compatible with the performance design of the engine   Just for the hell of it

Standard isn't always best. It depends on the design. Yes Omega engines can't be tuned easily, but obviously it depends on the manufacturer.
Take my Monaro for instance, gains of 33 bhp & 45 ft lbs of torque where achieved just by headers, 100 cell cats & a free flow system.
A mafless tune & cold air induction also adds extra bhp & torque.

Says it all really, I accept that "other cars" are different .. and in my youth spent many hours doing exactly that .. your Monaro is a "performance car" so can be tweaked ... the Omega is a LARGE EXECUTIVE SALOON and was never intended to be anything else ..

Fixed that for you Nige

I've always wondered if a V6 would benefit from headers, sports cats, CAI & if poss a Mafless Tune
Has anyone done owt similar?

[Kevin Wood]

The same induction system isn't restrictive on a 3.2, so it stands to reason that "improving" it on a 2.5 will make absolutely no difference.

On a 2.5, by far the most the only worthwhile step is changing to 3.0 cams.

I am using one of my Omega's (the 2.5) as a donor for my kit car. I intend running it on Omex or Emerald ECU and running a MAP sensor, no MAF.
I will go down the route of using a 'custom' intake set-up, retaining air temp sensor and hopefully some 'ram-air' effect/cold air from the front of the car.
Exhaust manifolds will be re-made, tubular style.

Not sure if it will/will not yield any more power, but i will also be running lighter flywheel/front pulley to reduce parasitic losses.

I will start a build thread eventually ! But i'll post RR results as i go.

Are 3.2 manifolds less restrictive than 3.0 ones

Hmmmm. Interesting. Yes keep us informed

Are 3.2 manifolds less restrictive than 3.0 ones 

Yes, they are a formed steel manifold as opposed to a thick walled iron casting.

 And a straight swop no doubt

will.. no doubt.. but the internals limit the gain and tuning requires some trial error with expensive tools.. and those hwo have that budget dont prefer omega..  if forged steel internals used/found and cooling redesigned ( dont know how) things may change.. but for less money there are better engines ready for that..
