I have stock 04 calipers and hoses and brackets I could sell you if you need them, or if you know someone with a catera that could use them....

Ask R-Caddy he has two of them and he knows what to do now. He should put the pics up.

Since the last gen Monaro (GTO) came out in 97, how much does it share with the Catera? Did anyone check if the front struts work? I'm guessing no but curious since the brakes work.

A LS1 Catera would be a nice conversion!

Strut mounts are the same. I've heard confusing reports on the struts/springs. R-Caddy says they don't work so I'll take his word for it as I have no experience with Cateras.

A little history lesson. The Catera and GTO share Opel Omega roots. The Catera is a direct descendant (built in the same German factory), while the GTO is a distant cousin. Holden widened the Omega unibody and restyled the sheetmetal slightly to make the Commodore. The roof has 2 covered seams where the new roof panel was inserted. The Omega was built for German Autobahns but Australian roads demand a heftier suspension so Holden redesigned it. Most of the front suspension was redesigned.

Commodore


Catera


They then turned the Commodore sedan into the Monaro coupe which was converted into the GTO. The Catera and GTO share very little. So far we've discovered that the front brake calipers & hoses (2004), F&R springs, rear shocks, front strut mounts, and rear trailing arm bushings will swap. The GTO front struts will not fit. Strangely enough, front bushings from the BMW M5 fit the Omega/Catera. I guess Opel & BMW use the same parts supplier.

The LS1 might fit but the engine bay is at least 2 inches narrower in the Catera so it's a squeeze. At least 2 owners are attempting the swap using Opel OMega V8 parts from Lingenfelter. Opel was going into production with an LS1 Omega when GM killed it.
http://www.cadillacforums.com/forums...-underway.html
http://www.cadillacforums.com/forums...cant-wait.html

Lingenfelter bought some of Opel's stock of Omega V8 parts to do Catera conversions but decided the market was too small to turn a profit. They built one before quitting. No LS1 in that car. This car packs a 7 Liter (427 cu.i.) V8 from a Corvette C5-R Le Mans endurance racer. I have some photos.

I know, I know. Why not buy a GTO? For some it's building something unique with their own hands. Others, the American hotrod spirit. But I think mostly it's that the owners are too lazy to have to put up with getting out of the car when a backseat passenger has to pee.

That 3800 catera should be bad ass. I always wanted to slam one of those bad boys into a Fiero.

Yeah I was over at R-Caddy's when he tried putting them on and they will not work.
R-Caddy knows what he is talking about when it comes to Cateras he has two. And mman have we worked on those. Him more than me, to be honest. lol
The front brakes from an 04 will work, and they do make a huge difference. He is still breaking them in, and I helped a little being the dd.
We are trying to find out what GTO parts will work with a Catera. The 04 GTO have more in common than my 06 does, but there are some things that I think will transfer over when I upgrade some parts.

That LS7 Catera is so bad ass, and a great sleeper. The only US Catera with a manual!
Cateras in general are great sleepers ask R-Caddy about the run in with the Porches we had going to a concert last Friday.

I grabbed my camera but sadly my batteries were out so no pictures I took it for a spin and I fell in love with it, that manual is a thing to die for... so if you can find one of the 238 units that they sold and you will be a lucky man... I doubt many more of these manual cars made it here but who knows... maybe one day I can find another and buy it.

My buddy ended up returning it the next day and he picked up a Subaru Legacy... something...something..., then I immediately tried to contact the dealer and see if it was there and they told me that the car had been sold... I was sooooo pissed, I wanted to trade mine for this one... but I was SOL...

Well you got me on that one. I gotta tell R-Caddy to inform better next time. How many of the supercharged Cateras were made. I know there wasn't many.

Thanks

I sold my calipers, but I still have stock rear shocks and stock rear springs (less than 10k miles). I'll sell 'em cheap, shipping will probably cost more than the parts. PM me.

No supercharged Cateras were ever made. The 2002 Cat that he saw had the revised normally aspirated 3.2 V6 that eventually went into the first Cadillac CTS. It also had a manual transmission which earlier Cateras never had.

I'd never heard of these 2002 Models before CateraMV6 reported his encounter. My Catera Sport is a 2001 and I thought that was the end of the line but he says 238 2002 models made it to the US. I wish I had seen it myself. I'm left wondering what other changes were made.

Well, with the brand spanking new 3.2's available, we can all have one Minus the 5-speed. I was told by this one guy here in Savannah that his aunt had a supercharged Cat, but he might have not known what he was talking about.

FWIW I have a set of front calipers, as well. I'm not sure if you bought some from another member, but if you still need a set PM me. I'm not looking to get much, but rather hook up a fellow member and car enthusiast.

they originally designed the catera with an ls1 engine but it would overheat after long autobahn sprints, I think

I thought the V8 thing was using the Northstar and the engine was only being used in the Opel Omega and not the Catera variant. I heard the same overheating issue as well being the killer.

The Opel Omega was designed to use the narrow 54* L81 V6 built in Ellesmere Port, Great Britain. The engine bay is too small for the NorthStar V8. With its DOHC heads it's too damned wide. Not sure about the length but no way is the Northstar as compact as the L81. Having a OHV head the LS1 is much narrower than the N*. It's part of the Small Block family of engines and, as V8s go, it's a pretty compact package. The biggest hindrances are probably the exhaust headers. These are actual Opel Omega V8 exhaust manifolds. You can see how they are flattened and dimpled to fit past the fender wells and other components.




This guy did it old school. He didn't use any Opel parts. He just took a junkyard Chevy 350 small block and shoehorned it in. Texas style. He didn't worry about the FI or electronic tranny. He's using a carburetor and an old GM Turbo-Hydramatic 700R4, 4 speed (non-electronic) transmission. Probably lost his ABS brakes but hey, he has a V8. Couldn't get it past the emissions police here in NY but maybe things are looser in TX.

Seems odd. With all of the engineering that most cars go through these days & GM can't fix an overheating problem. Stupid!
