Omega Electrical and Audio Help / Re: Basic's please.

« on: 01 March 2010, 15:15:05 »

Cheers for the responses folks, I'm watching a few on ebay now, also need a cage too, but I see a few are listed with cage as well.

Hopefully my wiring is correct and the display will work.

What was the base model CD player fitted to a 1998 Omega, where can I get one from, and how much are they, I only have a hole at the moment but want to put a standard unit back in that uses the display in the dash.

The car has the later MID with brake check at ignition on if that makes any difference

Cheers

Omega General Help / Re: Juddering

Could be the DMF on its' way out, of course. Or the spigot bearing.

Kevin

while I agree with the logic - it was all very sound when inspected, not very long ago...  :-/

The spigot bearing would make one hell of a lot of noise every time you press the clutch if it fails. It did on mine, though intetrestingly didn't make it judder!

In order to work the cat needs hot exhaust gas so has to be as close to the engine as is possible.

I've always run mine without the cats, the 1998 3.0L engine I have only has precat LAMBDA sensors so removing the cat's makes no difference to the ECU. I'm not sure if there is a power gain or not, as I've never tryed it with the cats, there not needed in my application.

Omega General Help / Re: 3.0 to 3.2 upgrade

« on: 10 September 2009, 15:17:24 »

Cheers for all the replys,

better bet is the Saab/GM 2.8V6 that engine can take alot of boost!

What is this engine, and will it mate to an R28?

Omega General Help / 3.0 to 3.2 upgrade

« on: 09 September 2009, 22:39:42 »

As the title really, I have a 3.0 fitted to an R28 box, the engine is being controled by a Bosch Motronic 2.8.1 ecu. If I wanted to fit the 3.2 will the gearbox still fit, I'm also guessing I'll need a different ecu?

Is the 3.2 a stronger engine, as in can it be safely supercharged? I think it would be asking a lot of the X30XE I currently have fitted.

If the answer to the above is yes, how much power gain would I be looking at, and would the R28 box cope? Can the ecu be remapped to accept the extra boost from the supercharger or do I need to look into a different one?


Remember this engine /  box combination is not fitted to an Omega! I scrapped an MOT failed ex-police MV6 estate to get all the parts needed.  This car is already really very rapid, as it only weighs 1200kg.









It will be in next months Practical Performance Car magazine coming out on the 24th of September.

Omega General Help / Re: Clutch release bearing

Cheers for the link a duel mass flywheel from them is £215 + VAT. Much cheeper than Vauxhalls £700.

Well, it's all appart and I've got my new clutch thrust / release bearing. Part No. 90465672.  It cost £66 

With everything appart I also found that the needle bearing in the end of the crank shaft had broken up. This is the bearing that carrys the end of the gearbox input shaft into the crank shaft and therefore supports the clutch. I have a new one of thoes on order as well now, part No. to follow, cost £3.61.

I'm guessing (hoping) this was responsible for all the noise. There's no noticable lateral play from the flywheel. I can by hand rotate one part a little with out the other by about 1 degree (or about 4mm if you were to draw a line on the outer face). Is this correct?

Ok, to add the the expense, the stealers want £700 for a flywheel 

Had a look on the Courtenay sport web site, they do a lightend one for £275 but I'll need the clutch kit to go with it at £195  so it's still costing me £470    Thats more than the car cost me!!!!

I'll take it all appart and hope that it is just the release bearing, if not I will be looking for alternatives or used ones. 

Any one fancy selling me a X30XE flywheel

All advice is welcome cheers. My local stealers quoted £66 for a release bearing    Is there a cheaper source, and how much will a DMF cost me?   Do they come with a clutch kit?

yep dual mass flywheel, just realised your the guy did the 999 challenge for ppc? in the scim?? nice!!!

Yep, that was me. It's rapid, thats for sure

I'm guessing the DMF also cause a vibration if failed. There is no vibration as such, just losts of noise?


Cheers

By DMF I assume you mean duel mass flywheel??  If so what goes wrong?

The noise I get sounds like say , loose wheel on a shopping trolly when spun fast and it vibrates. This happens every so often when I press the clutch pedel. It stops as soon as I release the pedel.

I think I'd be looking for a new-to-me bearing. The release bearing is an integral part of the concentric slave cylinder that lives inside the bellhousing around the input shaft, nothing like your Scimitar's separate items.

I'm using the R25-R28 gearbox with the X30XE engine so all standard Omega MV6 stuff. The clutch release bearing is a separate part to the slave cylinder.

My X30XE clutch relese bearing is on it's way out and makes loads of noise when the clutch pedal is pressed. I called my local dealer and he quoted £66 

What is the part no of this and where would you recommend I get one from?
