instead of an E60M5.
at the time i thought it was a hard decision but this proves it.

not to mention IMO the E55 is better looking, and the torque is great.

BMWs are great cars, and i have an M3, but ok.

so BMW came out with some kind of stroker motor for the M5. thats right. stroker. 5.7L V10.

For those seeking the ultimate high performance driving experience, Dinan has once again redefined M5 performance with a bored and stroked 5.7 liter version of BMW’s V-10 engine. The engine produces over 600 horsepower along with stump-pulling torque that exceeds 400 lb-ft from just 3000 rpm right to the rev-limit at 8100 rpm. As incredible as BMW’s V-10 is in stock form, just imagine the acceleration that results from an additional 141 horsepower and 128 lb-ft torque @ 5800 rpm! Equally impressive is the fact that all of this performance is available without sacrificing BMW-like drivability or the peace of mind that comes from matching new car warranty coverage for up to 4 years or 50,000 miles.

Dinan’s 29 years of BMW tuning and racing experience ensure that the engines will not only perform but also provide years of trouble free driving excitement. Much of the technology that has made Dinan’s Grand-Am Daytona Prototype engines both competitive and reliable has carried over to the 5.7 Liter V-10 engine program for the street, ensuring that the engines produce incredible power along with race-proven durability. Each engine is dyno-tested prior to shipment, verifying power output in the same rigorous manner employed for the Daytona Prototype racing engines.

The engine is supplied as an assembled long-block, fully prepared to directly replace the stock engine without modification. High Flow Intake/Air Mass Meter Assemblies are required in order to supply the larger engine with adequate airflow for maximum power gains. Maximum performance is achieved when the engine is equipped with the High Flow Throttle Bodies, Free Flow Mufflers and racing middle exhaust, producing an incredible 628 hp @ 7400 rpm and 482 lb-ft torque @ 6200 rpm. For those seeking ultimate performance from their M5, without sacrificing civility, reliability or warranty coverage, the Dinan 5.7 Liter V-10 is the definitive solution.

but wait.
what? they want 40k for it? and ur stock engine?
wow....


but my question is, how would this stack up to a bolt ons E55?

with green filters, exhaust, pulleys, throttle boot, software, and headers?

thats what? maybe 10k inc labor>

 

Too much to spend, to still have an M5.
$40K gets you a Lambo for a year.

 

if i read correctly its really 60k. 40k+ your stock motor which is worth 20k...

 

Dinan always has been horribly overpriced euro wannabe junk, always will be.

 

That is highway robbery! Do they make a turbo or supercharge kit for the M5 yet?

 

Guys that have already gone this route will be able to say for sure, but what I've been pricing lately major/"Stage 4" type mods will run you in the low $20's. Of course, with new products & services coming out (heads, etc.) that number will surely go up. This is also assuming getting all the work done in one shot; doing it bit by bit will increase labor costs as well.
