Omega Electrical and Audio Help / Re: Wiring diagram for clutch safety switch needed

« on: 26 December 2007, 01:01:41 »

Yup that's what I need.

From reading a few threads of people converting from autos to manuals, I do know for a fact that the clutch pedal has some kind of switch attached to it. So I presume that the European Omega's came with the safety switch that would interrupt the engine from starting should the clutch pedal not be depressed.

Omega Electrical and Audio Help / Wiring diagram for clutch safety switch needed

« on: 25 December 2007, 11:46:40 »

Just wondering if anyone could post the wiring diagram for the clutch safety switch. The Catera only came with an automatic so this is not in my service manual and I need this info for my conversion.

Thanks in advance

After doing some more research, I found that the US-spec ecu is designed to support OBD-ll , and coil-on-plug setup. Also it is designed to allow a very low rpm (450rpm range) why I have no idea.
I hope that with a little work and some R&D I can raise the compression, maybe open up the intake, add larger throttle body, maybe even port the heads a little. The US-spec is set between 9.8:1-10:1 compression where the Euro-spec is 10.8:1. I'm sure that makes alot of the difference. 180-190 bhp vs. 211 bhp. I'm gonna push for 11:1 on the compression. US-spec pistons may be the problem though. From what I'm told, they don't support anything more than 10:1 comp. The ecu will be a problem as well, being only designed for automatic transmission, I'm using a 5-speed manual. Also US-spec only supports electric throttle drive no cable. I'll figure that out.
Does anyone here know who builds the 5-speed tranny used in the FWD versions of the X30XE, or with the 2.5 or 3.2 Vectra?
Here they used a GETRAG.

The compression on the European and North American engines is the same.

Mechanically both engines are identical as is the power. Though the NA is rated at 200, it is in fact 210 just as the European is rated. I dyno'd my car to confirm this.

The main difference between the two cars is that the NA car had OBD-II before the European cars. Europe required it on all cars by 2000 IIRC, in NA it was 1996.

Can a member in the UK confirm what was the first year that had OBD-2?

Here's a look at the Caddy setup,

The car pictures is a 2000 or 2001

The ECU shown is the older 1997+1998 ECU. The 1999-2001 look different.

Omega General Help / Re: Auto gearbox selector lights come on.

So is the switch itself actually servicible?

Omega General Help / Auto gearbox selector lights on/off with headlight

« on: 17 November 2008, 10:54:26 »

Any ideas on this issue:

All of the shift position LEDS will remain OFF when the headlighs (lowbeam HID's) are ON. The selector lights will only turn ON when the headlights are OFF.

When I toggle the main headlight ON/OFF button located on the headlight switch, the shifter lights turn ON and OFF accordingly when they should remain ON at all times.

Omega General Help / Re: Polyurethane Control Arm Bushes??

« on: 17 September 2007, 00:18:24 »

I don't think that it is a good idea to use polyurathan or any hard compound for that matter in the rear pivot point of the front A-arm (bushing where the bolt that goes through it is vertical). Many cars use this type of front A-arm design and for proper suspension travel, it requires that this bushing be very flexible, otherwise the suspension can bind which will put a lot of stress onto the mount point of the subframe. This is likely why no company makes polyurathane bushings for the front of our cars.

Similarly on the 1993-02 F-bodies (Camaro, Trans Am) people were installing polyurathane bushings in the rear lower trailing arms not knowing that this was causing a very hazardous situation. For proper rear suspension travel on those cars, articulation in the bushing is critical otherwise the suspension will bind. Under certain loading situations, the trailing arm mount points on the body were twisting and sometimes stress cracks began to appear.

I would strongly recommend against using polyurathane. The stock ones last a very long time anyways.

Do you know if you can go larger than 8.5 on the front?

What is the widest wheel that anyone is aware of that has been installed on the front of an Omega?

I know 8.5 will fit, how much larger can you go?

I'm wondering if 9.5 will fit.

90K

what a car though, that would rock my world

At 90k I'm really unimpressed by this car.

I could easily make 1000 hp on my LS1 conversion and it would cost me 15k max.

He should have went with a better engine.

My car will also use the same transmission.

Interesting, it looks like they only switched the brake booster/master cylinder.

Does anyone know if the clutch pedal slave cylinder and pedal assembly (clutch, brake, cable op. accel)
was indentical to those on the LHD cars?

I will eventually need to have these parts shipped from Europe as the Catera only came with an automatic.

Speaking of LHD and RHD cars, would anyone have some good shots of the engine bay of a RHD Omega. I'd be interested in seeing what exactly they switched around. I can't find anything good on google.

Would this project work on a right hand drive car, the reason I ask is that you pointed out that the left side manifold is squished to fit the steering box, so does this mean that it will only fit a left hand drive car

Correct, you would not be able to use these manofolds on a RHD car. Opel had not plans to bring this car to the UK.
