Hi,
When my house sells (nov-dec hopefully) , i am going to buy another omega and strip it down and start a fresh with it. Its going to be called project Beast!I really want a big power engine but want to stick with a vauxhall engine.
What engine do you think would work well in an omega?
I am open to any type of displacement but would prefer a v6,v8,v10 or v12 , maybe turbo'd
Matt :)

No contest for me. Put a GM V8 in it and build the mythical Omega V8.
Tuning the V6 engines has too many snags, a turbocharged 4 pot wouldn't really cut it.
Got to be done.

What is the spec of it? , any websites i can have a look at it?
I fodgot to mention , i am going for a facelift car , and going to make it lighter by replacing parts with lighter ones.
The end result for me will be a car that has amazing interior , amazing exterior with amazing performance and handling!

5.7 V8 Monaro engine, won't be cheap but will scare everything in sight. :y
Failing that a BMW 4ltr V8 out of the 5 series?
-
yeah , dont want to use a bmw engine. vauxhall only

If you want big BHP you are best off slotting in a C20LET or the Z20LET. Turbo cars are so much easier to tune. I think the turbo will foul the engine mount so you would prob have to move it (engine mount), build a 3" straight through exhaust, fit LSD and have some serious fun :P

Hi,
I was considering that actually but was a bit worried about with it only being a 4 pot it would struggle with the weight.
Am i right in saying 300 Ibft of torque on a 4 pot wouldnt feel the same as 300 Ibft or torque on a v6 or v8 due to how it spits the torque out?
Wouldnt the z20let be thrashy and low on torque low down due to turbo lag?
I would much much prefer to take the v6 out and go to town on it and spend alot making it reliable and very powerful, just dont know if the v6 would take alot of power and be day to day reliable.
Matt
-
I see. I know what your saying about the 4 pot but I think it would be ok, your only going to get turbo lag until you know how to drive a turbo car ;) or if you have a mahoosive turbo - you'll get lag no matter what.
Pushing the V6 to any decent power will cost you dearly ie sale of vital organs on ebay etc...
I have a superchips ecu and twin de-cats and it's still not that fast.

Hi,
Yeah , ive driven quite a few turbo cars (astra gte c20let turbo) , and always found them to be very fast but bad for lag.
If i could strip the v6 and get better pistons, cams, etc and maybe supercharge it or turbo it then i would prefer that but if it would cost me a massive amount of money then i would prefer a new and different engine. I just dont know if the v6 would be reliable running say 300-400 bhp via a turbo or supercharger?

What ever engine you put in it can you make sure you do photos and a nice detailed list because im saving for the same thing. At the moment i've decided on http://www.strokerengine.com/BBC620.html as i want to bulid a street legal drag car. Ive been collecting info on parts and suppliers for the last 2 years but just need the money so if i can help with any ideas on parts and where to get them just let me know.

DOn't use the 2.5TD then
-
LS1 V8 or experiment with a supercharged V6
-
Agree with Kevin above...Beast need v6 or v8 engines.
The v6 in the 3.0 omega wont take much more - V8 it :) ;)

C36GET :y

Holden V8 lump :y
V8 is the only way to go
-
is that c36 engine the lotus carlton?
Matt
-
Yes
-
It's gotta be the 5.7 V8.......
We've seen LC engined Omega's before, 4 pot turbo just isn;t right for that big Omega chassis.
-
is that c36 engine the lotus carlton?
Matt
Yup...
-
Before i rack my brain on another engine.
Do you think the 3.2 engine could be a good engine to turbocharge or supercharge if i had a total rebuild with low comp pistons, steel crank, uprated gaskets, cams, valves, head etc?
I just really would prefer to use the original omega engine.
I would be wanting an engine for 400bhp approx , and would probably try and use a 6 speed gearbox from another car if possible.
Matt :y
-
3.2 Already has a steel crank IIRC.
That's a big hike in power, though, and it won't come cheap. I recall hearing that cooling is a problem on the v6 with even a modest power increase.
It'd almost certainly be more cost effective to buy a new crated LS engine that'll generate that sort of power out of the box.
Kevin
-
Aye, a holden/GM/monaro V8 is sounding a little bit tasty :) How's about supercharging it though!?! :D
6-speed is gonna make it the ultimate cruising mile muncher and drag strip extraordinaire ;D
-
Thinking about it i might stick with a v6 of some sort. V8 will be too noisy and thirsty.
Matt
-
Never heard a V8 that's too noisy myself 8-)
(includes my mate's 3.5 rover that we ran up for a quick test with no exhaust manifolds)
Kevin
-
Oh right! , i always thought they were noisy.
Ok , would consider getting a new ls1 engine with the 6 speed box and do that then.
Going to see if the dash could fit aswell.

I think you should aim to beat the norwegian guys:

Lexus V8. +/- 1000hp
-
Slightly changed my aim now.
I am going to buy a brand new 3.2 v6 from vauxhall (£1800) and either supercharge or turbocharge it.
Spoke to a local performance tuner who said roughly £2000 for a turbo conversion.
So hopefully if i used brand new parts for the whole engine and cooling i should be able to get a 300-400bhp motor that is reliable.
Matt
-
most easy change will be standard factory out GM V8..supercharging or turbocharging will not be long life and will bring many problems with cooling..
and if power is desired forget about the fuel issues
