The GM LS series is probably the most reliable engine ever made

And as for the weight issue, a large displacement V8 produces a level of torque from idle that a four pot turbo shastbox can only dream of . And as we all know, without torque, horsepower means nothing

Take the Monaro as an example, can be reliably supercharged to well over 500bhp, will reach the thick end of 170, even in standard tune, yet does barely 1500 rpm at 70mph (120kph). At that speed, your clit is probably doing nearer 4000rpm, and using almost as much fuel.

And knowing Renault parts prices, the V8 is cheaper to service too

my clit even 7K rpm consumes a0.00000.. fraction of a v8    seriously at 120 must be around 3K (5th) will check tomorrow..
 
renault is produced here (factory in Bursa) so parts relatively cheap compared to omega.. even I can change engine at every oil change   (exaggerating of course)
 
now as for service, your v8 takes twice oil, twice sparks , everything twice
 
days of big monsters are long gone.. may be not in America but here

LS1 = 188 kg Wet
M62B44 = 221 kg Dry (+ 9.15l of Oil)
C20XE = 145 kg Wet

Cant find the weight of a C20LET online, but I'd imagine marginally more than the C20XE for obvious reasons.

 
C20let around 130 kg.. and considering the axels, carrier weight and width for chasis will bring more weight to car

How can it be lighter than the XE?

probably similiar all I can find was this.. may be light flywheel..

Ls will do more MPG then omega 3.0 and 3.2 v6 i get 36 out my one at 80 on motorways

Around a see 28.5 but never sort sort runs...

aluminium block v8 is not dissimilar weight to y32se or x30xe due to having an iron block.

V6 lumps out of question anyway..  they are not race bred engines..

define a race bred engine?

Me,If I were thinking of a similar project I would be buying an old lexus LS400 (plenty around the £500 mark) and having a look at dropping its engine into an Omega.A really well engineered Japanese quadcam v8,rather than an old over engineered U.S. boat anchor.

As already said in the thread, Quad Cam engines are way too bulky, and from a performance POV, not much touches the LSx engine for size:power ratio.

engines originally designed for race.. they are later put to production for daily use with lower power rating..

LS7 with supercharger then

...being run on Moonshine or jetfuel

Obviously the Renault 1.4 fourpot was developed especially for circuit racing, only being fitted to 7 billion(ish) cars for homogolation purposes

It is indeed, and has been done in the rats omega. But the heads are wider, being dohc. They definitely fitted a rack with that engine.

LS or LS? .

Lexus is 4litre though? Although just as easily tunable. But then the Chevy v8 well, that's the one to have. But costs more.

Decisions decisions.



I suppose it depends which is most suitable to omega running gear. Cooling, Exhaust, Auxiliarys, ecu and security stuff....etc?


Not much matches a Chevy v8 though, its very hard to beat pound for pound on bhp. You might have to remove the box on a Chevy v8. Where as it definitely will have to come out with a dohc lump.
