its simple as this lads ye can do it the right way by cleaning your breathers torqing your bolts to 8 nm genuine gaskets etc etc and hope it dosent leak ...,.which it will sooner before later as it is a well known fault that they are rubbish, or you can slap on alloy covers like i did on my last two omegas with non genuine gaskets tightned by hand and never again get a leak its up to ye ,
also if this chap was looking for a smooth ride with an even curve bla bla bla he wouldnt be planning on modifying it
bin your dual ram put in a home made resonator box , job done .... may not be smooth but will be a damn lot more responsive for real time driving not plomasing on the motor way ,, tha is my opinion which i can tell you i experienced on MY car before and after and is not your usual hear say rubbish some people on here keep at , keep us updated with your findings ,
its refreshing to see an omega being modified on here , beats the usual topics about maintanence


Alot of miss informed info there, sorry. I'm sure the op will take whatever advice he chooses on what he does with his own car. But remember leaking cam covers are not confined to the omega. Numerous other marques fill thier plug wells with oil and cook the ignition system. The gaskets simply go hard with age and fail. The youngest omega will now be getting on for 8 years old, so until another set up has done similar comparable service life how can it be recommended? Plus the usual breather servicing is important true enough, again not an omega specific issue.  How on earth anyone managed to warp a cam cover given the internal webbing and structure... Seems odd to me, how can they warp?

Many a claim has been made on improving the induction system on here, yet to be proved beyond the classic "more noise equals more speed" . Of course if noise is what's wanted and a peaky uneven power delivery is what's considered an improvement then fine, go for it.

But if a simple biscuit tin plumbed into the inlet was worth while I'm sure vx would have included it, no? Any engine will be affected by emission constraints though so I'd start there, but de catting completely is advice that may not be appreciated come Mot time.

Alloy cam covers will obviously do nothing for performance.  The idea it cures leaks is a bit flawed - cam covers leak due to blocked breathers, poor quality parts, or poor workmanship, otherwise should be good for 7 or 8 years (so 1 set of replacement gaskets in its lifetime).

But if people want that alloy covers, thats fine and the owners choice - but must be made on the facts, not this myth put about by people who cannot fit them that the plastic ones warp (they don't).

If you do fit alloy ones, be aware the next weakest point when the breather system blocks is the crank seal. Thats a bit of a pain to replace, as Vectra owners will confirm.


The multiram is there to smooth out the torque curve. Removal won't do massive amounts for performance, but will make it a more stepped 'surge' with it removed.  The genuine GM filter is probably hard to beat for flow.


There must be some gains with remapping, also would be interested in gains from forced induction

Also the oil filler is far less conveniently placed under the fuel lines on omega.

if you want a decent trustworthy source for a remap then get in touch with John Robbins at DNA Tuning in Stratford upon Avon.

He writes the stuff for other tuners and does oem diagnostics.

I had my Golf 2.3 V5 done there (which also has just about zero tuning options) and the results were fab! Razor sharp throttle and gets rid of the flat sopts and allows it to rev up to the red line much easier - you may need to use 97/99 ron though.

I beg to differ that 20-30bhp will not be noticable! So, why bother having the 3.2 over the 2.6 then? Why bother having the 2.6 over the 2.2 ... OF COURSE 20BHP WILL BE WORTHWHILE!!!!!!!!!!!

To the op - you are asking some indepth questions about tuning options on this engine but appear to know nothing about the basics - read up my friend.

how much difference will make 20 hp on a 210 hp 1700 kg car on the clock ?   Huh

you loose some of it on drive train, tires and pressure plate.. let me answer 0.2 - 0.3 at best.. noticeable.. may be .. but the cars that let you in dust , will still  Cheesy Grin

better invest for better tires and smaller gear ratios..
