    • Dragstrip 1/4 mile comparison between the C63 AMG Coupe and Cadillac CTS-V coupe by Insideline

      The C63 AMG coupe and the CTS-V coupe are both beasts in a straight line. Insideline decided to find out which of the two is faster on the strip. The curb weight for the CTS-V is 4200 pounds versus the C63 AMG weighing in at a lighter 3,990. A 6 speed manual was the transmission chosen for the CTS-V while the C63 only has one transmission choice, a 7 speed automatic. The result? The CTS-V wins (barely) with a 12.2@117.5 against the C63's 12.3@116.3. Considering the CTS-V has a motor with a supercharger and barely edges out the naturally aspirated C63 that says a lot about how good the M156 is.

That power maybe useful on highway pulls but that's not really racing. Hell there's a shop by my house called vengeance racing that make some crazy LS motors and they cost less than a new N63 would cost for my 550.
        Trust me, I understand the LSX aftermarket and it is a thing of beauty. It just isn't as simple as $15k and 1200 whp from your car. You are essentially now saying a different block, motor, internals, etc., instead of modifying your motor.

        434 LSX block is just $2k?
        yup...only 2k for the block....27K is without the LSA trade tho....remember i said with the trade its 15k...the LSA is like 12-15k so the price sounds about right to me

        Yes but it isn't an LSA that is being built. To get 1200 rwhp out of your car you are advocating selling the motor and getting another one.

        I mean, I could do an LSX swap too...

        You could and it would be cheaper probably, and that's why he's saying it's a superior way to go. The advantage he has is that it would drop right in.

        Superior? Don't know about that. Cost effective? That sounds more accurate.

        You aren't turning an LSA into a 1200 whp beast for $15k, that is my point.

        That block will handle alot more than he's talking about! Sleeving an iron block? There's no need for that. He could make 1500whp out of those without worrying.

        Well let's see, he can make more power in an engine that has been proven reliable well beyond that level for less money. Sounds superior to me?

        The LSX block goes pretty far since it is cast iron. They claim even up to 2000 hp so yes the LSX block is strong as hell.

        I should have referred to the LSA, LS2, LS3, LS7 as LSX's needing sleeves.

        So engineering comes down to dollar per horse? Sorry, we would all be driving American V8's then. The S65 is a superior V8 to the LSA. The M156 is a superior motor. They are both better engineered from the factory and superior designs.

        We can agree here but the point is he doesn't need to because there are plenty of easy drop in options.

        Does not change my point. Going the aftermarket block route, etc., is no longer driving the same motor that came with the car. You might as well spec your CTS without a motor then.

        We obviously aren't talking stock for stock here(although that's up for debate as well) but the simple fact is if were talking about ultra high hp few motors not much is superior both in cost and reliability than the LS motors.

        Ultimately for super high end power nothing really beats a twin turbo LSX. 2000+ horsepower can be done. Doesn't change the fact the M156 is a motor with a superior design from the factory. Also, with twin turbos and an iron block it would go pretty far as well... we'll just never see it.

        Motor swaps and such are completely different territory.

        To be perfectly honest I'm not the least concerned which motor is superior in stock form as no car of mine would ever stay in stock form and for modifying it's tough to beat an LS but just out of curiosity what makes that M156 superior?

        if we pit cadillac, BMW, and Mercedes against each other in a price/hp battle and gave them all a set price across the board to work with the cadillac would definitely come out on top. Say you gave them 100k to work with....you get an M5 and E63 with all the trimmings....caddy tho will have another 20k to work with to make that car better.....im sure they will swap the block for an LSX and switch that 1.9 to whatever the largest thing they can get in there is and maybe even do some trans work.....the tranny in the V is whats really holding it back....they fix that and you have one MEAN machine....and it doesnt help the euros at all that the LSX LOVES the bottle....you can run 150-200 shots all day with no worries

        No one is debating dollar per horse.

        just giving my 2cents Click here to enlarge....i think i understand what your saying though is that the M156 is superior to the LSA , but i think we were trying to debate the fact that the LSX is superior to them all.

        Then what else is left to debate? Your post above saying everything was superior without giving one reason why was funny to me. You know there are 1,000hp NA lsx's? That the record for and N/A lsx is like 8.5 in the 1/4 mile? Hell I bet for the cost of a stock M156 I can get and NA LSX to twice the power and that thing will never break.
