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.

if I would choose an engine for race it would be a japanese not gm built..

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..

How can it be lighter than the XE?

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

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?

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

Such as...?

just google

Don't recall many Japanese engines being used in Nascar Surely if they're that good they would be everywhere...

Besides the LS family is alot less reliant on electronic black magic

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.

Plus, they had to cut the chassis on the rats omega, although its not clear exactly where. Might have been to make room for a turbo, or to make room for the heads. Chevy v8 doesn't need a turbo though, so one less job. I guess.

Honda VTEC no doubt?  Dreadful, DREADFUL engines!

you said reliability.. I wouldnt like to pump high volumes of oil on asphalt just in the beginning of race

Supercharger fits neatly on top as well

Nascar is an American race , isnt it ?

NASCAR is a U.S. series.They are a tad patriotic over there.
As for cutting the chassis etc. I have an angle grinder and a set of panel beating hammers.no worries.
No way imo,is any U.S. engine (or anything else in the field of engineering) going to be in the same league as a comparable Jap engine/ product.Its like comparing a harley to a Honda.

why do you think they choose Lexus?

If you read the link cem, I'm sure it tells you.

I'm afraid there are lots of enthusiasts thinking different

Probably had a smashed up one lying around

Technically Albs, but, hand on heart which would you prefer...

Spotty Yoofs know nothing. Some people eat semolina, doesn't make it gourmet though (or edible)
