Does anyone on the forum know of anyone with an LS9 crate engine in their G8?

That would be cool just to say you had it but money wise not as good of an idea. My opinion though

Probably would cost more than the car is worth.

Never heard of anyone doing it. Don't know why anyone would either considering you could build an even stronger LS3 for 1/3 the price.

 

[GXPaycheck]

Hasn't been done yet. Would be nice to see though!

Don't know of any G8 swaps but here is a link to a Gen 5 Camaro that has one. Interesting read but the $35K plus price hurts. Cheers.

Would be cool, but pricey... Certainly would have the "it," factor.

Would it be worth it for the cost? I can think of alternative routes to get the same horsepower at half the price point.

Not to me, I would just build a really bad ass LS3 for a 1/4th of the cost. But if you can drop 35k on a motor like that, it's probably chump change to them.

The LS 9 would be great but I would love to do a BIG cubic inch n/a LSX based motor around 480 - 500 c.i. with good drivability.

but and LSA blower on an LS3 and its basically the same thing, I know a guy right now is putting the LSA blower in his car, but I dont remember if its an L76 or LS3

How would you build an LS3 stronger than a LS9?

With better parts than the ones GM picked out. opcorn2:

 

[Ghostnotes]

Do these blocks have the same specs as the first gen 454 small block?? If so, I would not do it. Cyl wall thickness is right on the edge and they do not recommend going past factory pressures.

Both are basically the same engine, 6.2L small block, but the LS9 is supercharged from factory. New headers, cam, stall, maggie, and a tune would probably be more powerful than a stock LS9 and would probably cost 10k less than a crate LS9, which is 21k.

I was thinking about the LS9's durability features, like oil jets to cool the pistons, thicker head bolts, and stronger block and heads. The block and heads are the same design as LS3/L92, but use the "roto-cast" method to make the aluminum more dense. The LS9 block also uses billet steel main caps instead of cast iron.

The best way to do this is have a top engine builder build you a 415-418ci LS3 using all the best parts, then hang twin turbos on it, and drop that in your ZR1. Then, take the old LS9 and put it in your G8. That way the LS9 is free, you only have to pay labor, or just do it yourself!
