I know of quite a lot of people using these in opel mantas (I am involved with the club) and they are not that good an engine to be honest. Rather
fragile and very prone to cyl head gasket trouble/casting failures, and bits cost a fortune! Sorry!

Bit heavy (made of iron) but better than a cologne V6 that a few people use. Would need to get a RWD box. Correct number of cylinders though. Would
probably be unique among locosts too.

Certainly is!! there's something cool about doing something nobody else is. A sense of pioneering, or something. Be warned though that going
it alone adds time to the project. But fitting a different engine isn't all that crazy. Especially if there's actually a RWD gearbox
that fits it - what a luxury.
Can't beat a V6. But do whatever you think is best/easiest. What's a manta engine when it's at home? 20XE or somethin older?

Manta engine is older than XE, 1960s technology, cam in head cast iron beast. In GT/E trim it's 110bhp. Quite tuneable fit Mahle domed pistons,
phase4 crossflow head, twin 45s - now you're talking. Better bet would be 1.8s single cam running twin 40s, good for 140bhp - has the advantage
that started motor is on right side (left actually). 2.5v6 same engine as Omega - RWD so gearbox no problem.

IMHO
Sorry Liam you're wrong. Engine is all alloy.
My Omega's done 160K+, weeps oil from nearside cam cover oil seal, and yes the headgasket(s) will need doing next year. But what the heack if
they only need doing every 160K then I aint never going to do them again.
When you do the engine fit just make sure that you change the cambelt and all the tensioners/idlers. Piece of cake job.
Gearboxes out of manual Omegas (V6's) will fit no probs.
Best thing is that Lurvly Vauxhall V6 Growl.
Enjoy.

I think the thread got confused by my mention of mantas!!
I meant I know of several people who have fitted the GM ALL ALLOY V6 in 2.5 and 3.0 formats, to Opel Mantas, replacing the std very heavy CIH engine.
(I am on my 6th manta now I think, done 2.0 CIH, 2.2CIH, 2.0XE 16V on throttle bodies, now 2.0 8v SEH engine, assisting with supercharged SEH
conversion and V8 too!)
There are a number of problems with the engine. Yes head gaskets can last 160,000, one I know went at 68,000 and one at 55,000 so a bit variable
there! Yep, the pulleys and cambelt are a must, but so is getting a complete donor car with keys. If not and you wish to use the std injection system,
you'll struggle as it needs the chipped key to de-imobilise the engine ECU (and the key from another car won't do it, they are unique).
Getting the right codes is not easy!!!! Ok, if you put throttle bodies on it and an aftermarket ecu then you'll be ok, but that's not the
work of a moment (and not cheap, even in done "cheaply"

Huuuuuuuuuuuuuuh???
Any vauxhall V6 i've seen so far has had a steel block, OK with ally heads. That includes Cavalier and Vectra V6s and even the latest 3.2 in a
2004 Signum. I'm pretty certain the C25XE, X25XE, X30XE, Y26SE and Y32SE (old 2.5 cav up to new 3.2 signum) all have cast steel blocks.
I know GM have recently introduced alloy V6s (2003) but I dont know if they're in vauxhalls yet. You really have an old Omega with an alloy
V6???!!! What model/year? Are you totally sure? I'm almost certain you'll find it's got a steel block, but I'd love to be
proved wrong. Maybe somebody has painted it grey

Booooooo
According to the blokes at migweb performance vauxhall forums all Vauxhall V6s in current use have iron blocks. Damn thought there might have been a
cheap, available ally V6 I missed.

Mmm maybe. The V6 is nicer than a colgne, though.
The Y22SE (2.2 4-pot in vx220 and some new astras and vectras) is all alloy though. Nice engine and will make a good donor in years to come.

Oh yes, definitely better than a cologne other than cost! I love the old cologne engine for wht it does i.e. power a big 4x4 Sierra (my road car) for
huge mileages with very little maintainance, but it's far too heavy (in my opinion) for a locost.

ok here goes i have been offered for 50 sheets an ex police omega estate complete car not sure about the keys will check had a side shunt covered
127k running well 3weeks ago recovered after accident to my friends garage. it looks to big to me because of the air intake pretrudes about 6 inches
in front of block and, engine appears to look very wide so really wanted to appeal to anyonu who knows it will fit. infact just received a text
saying hes got another one in saloon thats two for 50 quid. Its not that i particularly want to fit this but dont really want to fit a ford
engine thanx 4 the input so far martin

Inlet manifolding is only plastic pipe & can be re-routed/shortened (just see how they squeeze it into a Cavalier/Vectra).
Width probably no worse than Ford cologne, but , Vauxhall is (32 - EDIT OOPSS, My head is seriously screwed with this cold/flu. Should read 6x4
= 24)24 Valve double overhead cams with hydraulic lifters and it just don't get the timing clatter that a long in the tooth cologne gets.
AND if they are genuine ex-plod then they should be 3.0 versions, possibly.
GO ON. YOU KNOW YOU WANT TO.
Use the vauxhall running gear (probably LSD rear end) brakes should be usable with or with abs, and the job won't be that much different from a
Granada as a donor.
Enjoy. (given up counting the days now but its getting closer )
Sorry lads but my maths was crap 32 valve would have been V8

32 valves!!! Oh my god!!
But damn! Two phat 3 litre V6s with RWD boxes and IRS axles for 50 notes!!!
Get them!!! Looks like you could move those two fat air pipes, but then why bother - there aint much going on in the front of a locost right there.
Get the engine as far back as possible and there's even more space. Could you just shove a pair of K&Ns on the throttle boddies or does all
that extra gubbins incorporate air flow meters that you need to keep?
Look's about as wide as a cologne and probably even a bit lower. Sump has very wide extensions on the bottom, but shouldn't be a
problem.
Should be a geat donor for a muscular locost! Yeah!

Cheap-as-chips rear drive all-alloy 24v V6? No such thing as a cheap Alfa over here, but plenty of Nissan 300Z (the one in Ward's 10 best
engines for the last 11 years) for under 500lbs (engine, box, diff, alloy hubs, big discs)

i had a cavalier new in Lreg that had the 2.5 v6.
fantastic engine
did 7.5 secs and 145 in a friggin cavalier!
took it to get fuel with my wife driving once. when i came back to the car she was sitting in it revving at about 4,000 rpm.
'dear, what is it you are doing' I cried (or words to that effect).
she had the radio on, and had stuck her foot on the trottle. the engine was so smooth she couldnt hear or feel it screaming for help.
I drove it down the a14 once, got to 130mph and it started misfiring. took me a few secs to realise it was the limiter cutting in at the top of 4th
gear  very smooth - but not that torquey - you need to rev it.
great fun, for no money nowadays. it looks like a nothing vauxhall - nothing shows thats its actually a quite quick car from the outside
