Omega General Help / Re: 2001 caddie catera *ahem* opel omega engine swaps

I have a small problem with this line as well ...

On the turbo Omega 3.0i V6 24V MV6 models you will see these power gains from anywhere between 270.4bhp to 395.2bhp

D'Oh !!!!!!!!!!!!!!!!!!!

...went into why i was inquiring about 3.2 engine instead of another 3l a few times, and that is obviously not the only source discussing cams, heads, induction, etc. to just jam in a lS1 with vette gearbox, and gto differential would be theoretically preferential, yet i know of only 2 people in the world who have done it with this car and it was a monumental headache. looks like cts engine with some aftermarket accessories is the easiest swap.

this factory catera engine in LA on ebay is labeled as a 3.0l but the description says it's a 3.2l http://cgi.ebay.com/ebaymotors/CADILLAC-CATERA-ENGINE-NEW-3-0-97-98-99-00-01-02-V6-_W0QQcmdZViewItemQQhashZitem5886117085QQitemZ380206411909QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories#ht_596wt_729
i heard of a guy in LA that bought catera's 2002 and 2003 engines when GM dropped the cars in the u.s. in favor of the CTS, so it looks like the 3.2 CTS AND the 3.2 catera/omega factory engines are available here, so i could do either one.

What were the reliability issues?

Here they are bullet proof if the cambelt and oil is changed at the correct intervals

as far as the 1st 3.2 cts's go, i've heard 1st hand about timing chain problems over and over, with lots of oil leaking out of seals, engine failure...  i think they fixed a lot of that pretty quickly, though.

the early cateras over here had timing belt tensioner failures, valve problems, stories of oil cooler problems, and occasional engine failures.

both early cts and early catera problems were addressed and improvements made, but they didn't occur outside the belt maintenance schedules. they were just plain defects. also, the early cateras had more stuff plugged into the omega electrical system than the omegas over there, so turning on the radio could effect your sunroof or virtually anything else electrical in the car.

2001 was probably the best catera but the cts was already being built in 2002 while last cateras were sold and cts hit the dealerships in 2003.  mark's link to the 2004 cts engine is still tempting, though. mating it to the transmission, electrical, mounting, is probably the easiest swap, but would love to get a cts 3.6 in there.

appreciate the responces, even though the direction seems to be headed back to domestic caddie parts.

Bargain!

thanks for that. i was thinking about that, initially, but those engines were about as reliable as the early mv6's were (not very). cts has a 3.6 as well, but then i need to start looking how different the mounts and wiring and all that are. i would prefer a cts 3.6 engine in the catera over a cts, and the cts would probably cost more than just the engine (if the swap was doable without headaches)

appreciate the responces. no info on any difference in reliability between the 3.2l and 3l mv6?

we never got the 3.2l in the states so i don't have anyone to ask. i KNOW it would be easy to get another 3.0 catera engine, but i explained my reasoning for the swap in my question: if 3.2 was more reliable, tuning it for more power would also be easier than the 3l. i haven't heard of any omega engine swaps that weren't one offs with major headaches. what is the EASIEST swap with the most upside? i really like the car and think putting $3-$4k into it would be much better than spending a few thousand more for a car i don't like.  have a great day, people

i have a 2001 cadilac catera, which is a rebranded 3.0l mv6 omega saloon *edited* sold in the states. i bought it at an auction in 2006, bought a jetta turbo at auction in 08 to replace it, but after driving the jetta for a month realized how spoiled i had become driving the catera (omega) and wound up selling the jetta. i live in florida and this car has spent it's whole life in florida so, other than normal wear and tear, it's in really good shape.

rather than buying another car at some point, i was thinking about just putting a few thousand into the catera. one thing i would not want to do is put in another 3.0l mv6 engine as i know they aren't reliable (mine had valve work before i got it) and the possibility of putting in something more powerful is too tempting.

my first question would be, what would the general consensus be here on the reliability/performance of the 2003 3.2l omega engine? if i could find a rebuilt or low mileage engine on that side of the ocean and have it sent here, somehow, wouldn't that be the easiest engine to swap with the 2001 engine? every other engine swap idea i have seen really seems like a massive headache, especially as far as new wiring harnesses and computers.

i searched this forum and i failed to find anything about swapping an 03 engine into an 01 (sorry if i missed it). there is A LOT of info out there on tuning up a 3.2 omega engine so if the 3.2l is reliable and an easy swap, then tuning one up in my car for $3,000-$4,000 would be much better than buying another car for thousands more that i won't like as much.  http://www.carref.co.uk/vauxhall-omega-30i-v6-24v-mv6-tuning.php
