why not rip out the stock ls7 and drop in a cosworth v8, bmw s65, mercedes m157 5.5l bi turbo v8, or even the kms c6r engine



anybody know anything about engine swaps, costs associated with this?

JoesC5

Most, if not all, of the engines that you would consider are DOHC. Might have a problem getting them into the cramped engine compartment of the C6.

Mr. Gizmo

Call Gas Monkey Garage. They might have an idea on the cost of creating this frankenstein. Heck throw an Lt5 LPE 415 CI 600hp motor in it.

I personally would prefer an LSX 454. Those can be built reliably to 700 horse. That would probably weigh less than the BMW or Mercedes motors you describe,.

I'm thinking of pulling my duramax out of the work truck. Lol. Torque monster and decent fuel mileage.

Gas Monkey that's a good one or maybe the other group that left doing the other wacky builds.

i dont really need high HP 505 is plenty lol i just need a car that lasts 5 years daily driving and occasional track days...faster than a Porsche caymen, sexier than a 911s but with all the reliability of them both (main issues with the two above are not catastrophic engine failure - 2009+ caymen has oil starvation issues without an upgrade, clutch problems and power steering problems under extreme abuse , 2009+ 911 has some water problems, crack engine problems if you track it hard without maintaing the car but those problems arent magically dropping a valve unexpectedly)

Why not sell your car and get a GS? The LS3 has proven to be a reliable engine--unless I'm missing something.

I've decided that if I blow my LS7, I'll go with a LS3 crate engine with the dry sump (made for a GS coupe with a M6) and drop it in. Then to make up for the lost 69 horsepower, I'll place a Magnuson Heartbeat supercharger on top for an additional 120 horses(624 HP). I will end up with around 85-90 pounds of additional weight, but still be lighter than a GS with only 436 HP. I'll save some weight as the LS3 is 10 pounds lighter than the LS7.

The stock 2006 C6 Z06(3130 pounds) has a 49.3/50.7 weight distribution, so adding the extra weight(85 pounds) of the supercharger on the front will most likely only take the weight distribution to 50.8/49.2. Still a little better than the 51/49 weight distribution of the ZR1 or the C7 Z06.

Since my Z06 is a 2009(3175 pounds), it most likely is better then 49.3/50.7 as it is 45 pounds heavier than the 2006 but most of that additional weight was added to the rear of the car, with the stronger TR6060 transmission(heavier), stronger rear end(heavier) and stronger rear axles(heavier).

I can add 75 pounds in the rear of my 2009's cargo area(properly secured, of course) and maintain the 49.3/51.7 weight distribution with the addition of a supercharger and only be 20 pounds heavier than a GS. 2006 & 2007 would be lighter than a GS.

Or I can drop in the LS3, do a few mods to bring the horsepower at the crank up to 505(not that difficult to add an additional 69 horsepower to the LS3), keeping it N/A and not adding any additional weight.

No need to trade my car for a GS.

Troll la la la la

Mr. Gizmo

if this is all you want all. thats not such a tall order -- buy a 2005 or 2006 C6 base model. Its got all of what you describe for 20-25k or a c5 z06 fo 20k. A lot less hassle and a lot less money.

univerz06

actually started thinking about it

Oleman

Agreed

univerz06

*clears throat* being born in 88 let me show you how to properly flame someone

put the stunner shades on boys...this flame is going to 11

you are a non factor which is worse than a troll - I would say feel that burn but your leathery skin handles the heat like the dumpster of a comment you posted.

I hate to tell you this but the swaps usually go the other way. The GM LS engines give you more HP with better reliability in a physically smaller and lighter package. There are kits to swap GM engines into Porsches, BMWs, Miata, etc. I have never seen one go the other way. Most of the other engine packages are just too large (length, width and height) to fit in the Vettes engine compartment. They may have fancy DOHC engines with all of the so called efficiencies and power advantages of 4 valves per cylinder but they can't pack the punch into a small package. All of that extra valve gear does add to eventual reliability/maintenance issues since there is more to go wrong.

Not a bad contingency plan if you're not married to the idea of an LS7. I have a buddy with a '10 GS with an E-force, and my dad has a '12 Callaway GS. Either of those are no joke...and they started life as a GS rather than a Z06.

univerz06

thats actually a good point...

RenoC6Z06

The LS7 is awesome why would you swap it for some POS? The s65 is terrible my wifes stock e92 gave up at 40k and it has no power.

univerz06

yeaahhh it can be made to be awesome....still learning about this though...but seems like it can be relatively reliable with some proper parts and a good maintenance plan (which i guess is like any car really) "pick your poison" comes to mind

cheers
