Hence reply number 5.

Stick a proper engine in it

I said a proper engine, not a blow drier

Don't forget that Mitsubishi is Japanese for "that will cost three kidneys. You have two, who is providing the third?"

[Raeturbo]

😂😂. At you both I’m mid elevens now with my hair drier 😂

I know the 3.2 has a stronger crank and a lower CR to start with, but remember those idiots at Courtney plopped a turbo on some of the early 3.0 cars, and all quickly suffered bottom end issues.

it puzzles me when people claim that the omega v6 has cooling issues (meaning the water cooling) - if that were true we should see lots of head gasket failures due to cooked engines.
What they do have is an oiling system that is about right for a 200bhp v6. V engines pack two big ends into the space  where an inline has only one. If you want to generate significantly more power you need to increase the oil flow to give the bearings a chance and to provide more cooling to the piston crowns.

2.5 and 3.0 engines of a particular build series suffer from external head gasket failure around the rear of the 246 head... Seems to be almost as guaranteed as crank sensor failure.

That said, the only people who have managed to break a 3.2 have the mechanical sympathy of a volcano.

'Buying the car new twenty years ago and immediately replacing the coolant with rock hard tap water and the oil with ATF and never changing either whilst driving everywhere flat out with the gearbox stuck in 2nd' type of abuse.

Not really, and probably not heat related.  MY97.5 3.0l (only) seem a little prone, though not "common" - I think on OOF, we can count maybe a maximum of half a dozen instances, with 2 of those being mine. 1 was MaxV6, I think JamesV6CDX came across one (actually, that might have been MaxV6's)....

It doesn't matter if you're going to lift the heads for performance modifications....
In fact, an engine that already has such a failure would be a good, cheap buy as it would be worthless to anyone else.


Tuning a 2.5/2.6 is pointless.

[Varche]

What about losing weight off the car.

There must  be a lot of weight you could pare off?

^^^^ This!

Had a 2.6 with G cams etc etc, just no comparison to a 3.2, makes the right noises but that's about it.

Has to be the best way to make an Omega faster. Its a very heavy car, and quite al ot of that weight could be shed if you dont mind losing a bit of luxury.

Ever been in a car with a stripped interior? It's like climbing into a steel oil drum and having a football team beat the outside with baseball bats. There are sharp edges every where and it looks shit.


You would have to really need any marginal performance increase to put up with one.


I've never understood the fascination of trying to turn a big, comfortable heavy small(ish) engined saloon into a track and road  car by removing all the features that were the original appeal.


And yes, I have tried removing the interior for an increase in performance. We did it at the track during the lunchtime shutdown. Taking all four seats, carpet, sound deadening and the door cards made no difference to 1/4 mile time of a 2.0l Capri, which as a low power car should benefit.

[Migv6 le Frog Fan]

Capri was light as a feather compared to an Omega though. One Omega front seat probably weighs as much as a complete Capri interior.
I agree about trying to turn a big heavy comfy barge into a track / fast road car though.
Its a bit like the old Irish joke "can you tell me the way to Dublin please ?"
"Well, I wouldnt start from here." 
However, if someone really wants to do it, shedding weight would be the best way to go imo.
Not just for straight line performance, but also for braking & cornering.
