Normally to get a lot of power from a small engine you have to tune the cams for high RPM operation. VTEC let Honda do this without sacrificing low and mid range power.

Yamaha makes the best engine in their V-Max(V-Boost)

"Compression on my 1.9 4-banger is like 10:1. It requies 89 min Octane or the valves start to get angry."

Poor design

The LT1 in my Buick runs at 10.5:1 and runs fine on 87.

The Japanese build great 4-bangers and the Euros make some nice 6's, but nobody builds a V-8 as well as the Yanks.

The M54 is the most reliable BMW engine ever built. Here's why:

The camshaft chain drive and the V-belt drive are maintenance-free and designed for the life of the engine.

Valve clearances are kept consistent throughout the entire running life of the engine by a self-adjusting hydraulic valve clearance mechanism. There is no need to adjust valve clearances, ever.

There is no need to reset the clutch since it is self-adjusting.
The air filters and spark plugs only have to be replaced after 100,000 km or 62,000 miles.

The oil in the transmission and final drive is a lifetime filling not requiring any replacement.

The engine is able to adjust automatically to all fuel grades between 87 and 98 octane.

Anti-knock control automatically adjusts the engine's running conditions to the respective fuel grade and quality.

Copied and pasted (what did you expect?)

FWIW: It was the M50 that sold me on BMW, after driving a 1992 5 series with 180,000 miles on it. The M54 just improved on the M50 and M52.

Rip,

Those are the same specs that GM uses on their high-end motors

The LS1 is supposed to go 100,000 miles with no maintenance other than oil changes. Other than 2 unnecessary spark plug changes, I've done nothing to my engine other than oil changes and 4 racing seasons and it's still running. I'm even on the original brakes and clutch after 102,000 miles.

Less than fully competent drivers are often to blame for reliability "problems". Most F-body drivers are kids with no real driving training, so they abuse the parts to the point where they fail before the expected lifespan. I've driven my car hard but smart, and it's lasted longer than GM expected, and way beyond any industry standard. To contrast, my wife was taught to keep her foot on the clutch pedal at all times so she burned out 2 clutches before I realized what she was doing and gave her a little instruction. How many cars get a bad rep due to incompetent drivers?

I wish we could get the BMW Diesel 3-litre Twin-Turbo (535d) here in the states.

Rgr that eagl, the LS1 is a fine, fine engine!

is LS-1 only installed in corvette engines?

is F-body refered to the late Camaros and Firebirds?

eagl · « **Reply #24 on:** June 16, 2005, 02:55:23 PM »

LS-1 was in corvettes from '97 to around 2004. LS-1 was in F-body (Camaro and firebird / trans-am) from 1998 to 2004.

What do you think of the new LS7?

500 horsepower (373 kw) at 6200 rpm
475 lb.-ft. of torque (657 Nm) at 4800 rpm

Gimme gimme gimme (A lotto ticket!)

The LS7 is cool... More displacement = more power. It's a bit closer to the edge for easy performance increases however, so getting more power out of that motor will cost more than an equivalent increase from an LS-1.

Still, there is a lot to be said for starting from 500 hp instead of 340 hp. The motor is damn near bulletproof so you can expect that a stock LS7 would run 100,000 miles without significant issues if it's not abused.
