days of bulky athmopheric high volume v8 engines is long gone imo..
 
today if I would choose an engine it must have
 
less weight ,
less cylinders to service,
need less space
and relatively higher hp..
 
but thats my opinion..  and no need to be same as GM..

Yet your turbo ing a v6 with cast iron block of similar weight, that won't produce the same power without shifting itself. And yet you really like the monaro with the same engine.... ::)

must say I really like older design monaros but they are not existent here.. :-\

Pontiac GTO is the same car :y plenty of US servicemen in that part of the world...

thats a good info :y


I think the politician needs to sort his manifesto out. ::) ;D

I like the monaros design as it has somewhat similiar to omegas curves.. :)  but that doesnt mean I will buy it..
 
honestly I also dont know what to do with miggy.. I can spend money and modify it , but that money will have no return except some joy and speeding tickets..  besides its consumption will be far from practical , let alone being economical.. and I cant hammer it in crowded city except late nights and early weekend hours.. yesterday tested the new cams, performance better but way too far from my expectations.. however, I dont plan to enter local drags either ;D     dont know really..
 
there in UK you can buy an over avg sports car for the omega money(here).. but taxes and insurance costs (here) immense to say the least..
 
 if I was there recipe was clear .. but here things really different.. :(

F1 engines obviously available though. ..? ::) ;)

IMO, as others have said and discovered here, super/turbo charging gm v6 will destroy the bottom end. Forced induction ain't for omega. You know that, you've been on here long enough surely? :)

3.0 top end is known to work obviously. ...manifolds? Oe are a chamber type manifold. Perhaps a tubular single pipe per cylinder design maybe?

Or the 2.8 turbo option? Straight 6turbo maybe for you?

no worries, if I decide on that route I will go whole forged setup, different cooling and different bottom end.. and not turbo either..
 
here some firms can build custom parts and I wont need to pay unnecessary cargo and import taxes.. etc etc..
 
but as I said in that case omega will definitely be a weekend car :-\

As I understand it, the main bearing journals are the weakness. 2.5 2.6 3.0 and 3.2 all have two bolt main bearings. (LS* gm v8 has 4bolt mains man enough for mega bhp, even in an alloy block) wonder is there a way to strengthen the crank case and crank bearing caps. ..? Probably not. :(

Maybe 2woody will post?

good info.. :y
 
 I'm sure some alternatives can be planned before trying the "next engine please" ;D

Very good find cem. This bit interested me as I have been looking at the more modern, more powerful and more economical 3.6 for sometime, wondering where it is a 60deg V whether it would fit an Omega. Now I have my answer:

"For the South American market are two modified from the popular 3.8-liter V6 ECOTEC 3.6-liter V6 available (244 hp and 265 hp), the V8 versions are not. The V6 engines are modern four-valve engines with SFI fuel injection. Both engines are equipped with the well-known from the Omega Y25DT 5-speed automatic transmission GM 5L-40E."

This to me look as good route to go if you want a more powerful, modern engine in an Omega, with a 5-speed auto box. My understanding is that this also gives better MPG than 3.0/3.2 and being all alloy is much lighter.

I wonder what a write off Omega from South America would cost as a donor car.  :) :) :) :)

Alot of effort and cost for an extra 26bhp and 47bhp gain respectively. Plus a lighter engine will need the front suspension re springing. Then the import costs...?

But if it will take some tuning ...?


Seems to me if looking to swap out an imported engine, import one with some woompf. :)

Ps, sure that lump is available in the states.

You are correct on the US. The one to go for would be the Camero 2010-2011 312hp, 278lbs-ft LLT or 2012-> 323hp, 278lb-ft
Which would give you about 50% more over standard and I would expect a much lower first gear with a 5-speed autobox.

There are also 304hp 273lb-ft LLC fitted to the Cadillac STS from 2008-2011, which maybe the best option when looking for a donor write off at a reasonable price.

Fuel consumption is reasonable: http://www.car-emissions.com/cars/view/28301

http://en.wikipedia.org/wiki/GM_High_Feature_engine

My thinking is what can you do for more power and still get around current 3.0 Miggy fuel consumption. With the 3.6 Extra-Urban fuel consumption of 37.7mpg, which I suspect would be around 30-33 in real world condition, you would be looking at 45-50mpg costs with LPG.  :y :y :y Of course we would all like to put a Vette V8 in our Miggy but I suspect for many the runny costs would not make it very practical.  ::)

If 50% more power and 40% more torque with a 3.6 V6 is not worth it, then best you stick to your F1 engine plan.  :P :P ;D ;D ;D

A couple of points... 
1. The 3.8 v6 is readily available, and quite often Supercharged, although mostly wwd :y

2. US gallons are a completely different size to ours, so measure the mpg carefully :y

A couple of grand would see summat with four wheels and a working engine over here. There is also potentially a salvage route from Brazil and the Middle East which could provide access to some off GMs finest examples of 'Rest of World' badge engineering :-\

WoooOOOOooooo so the politician wants to move the goal posts with different figures aye?

The combined figure is 25.5 mpg Rods. With an urban figure if 16 mpg. ::) and I don't believe that for a minute. Those figures are nearer the v8.

There's an sts on auto trader btw. 11k

//Mr Admin hat on...

Mr Gixer, could you refrain from being quite so aggressive to those who wish to look at other options beyond a V8.

Apologies if its just light hearted banter, but it doesn't seem to come across that way.

Merci Bucket.
