The Ten Worst "High-Performance" Engines Of All Time

Why it only moves us to tears: Not a terrible engine, but a terrible application and the collapse of a reputation. Mitsubishi's third-generation Eclipse foreswore the nameplate's import-tuner terror attitude in favor of a softer, more mature outlook; the clearest example of this change was the move from turbo-4 power to this comparatively big and lazy V6. Streetfighter gone suburban bland, the Eclipse remains a bit lost.

In the eclipse platform, ofcourse.

lol I like his wording ;) I had a Stratus R/T w/that SOHC and it really wasn't that bad. Still pushed out 200HP a decade ago and it took very well to opening up the intake and exhaust w/headers, full exhaust, ported intake and what nots. Funny they say that it went from streetfighter to suburban bland in contrast w/the GSX...but after doing those little goodies I had a throatier car than a lightly modded GSX and GST. Lawl :)

Did anyone give them a 3S SL or a R/T to work with? Seriously why the hell would they try an eclipse... Stock... :facepalm: stupid article. When you go test a class you don't go give the special needs kid a test then base the entire class on what that kid did.... ugh....

3.0 L that doesn't get anywhere near it's 220 hp rated output (unless you call 30% drivetrain loss normal) in sohc or dohc form. pretty crappy. a tensioner where belt tension actually loosens the pulley. 15.5mm wide rod journals. They don't even make rod bearings below 17mm for most race applications. honda can create MORE total power missing 2 cylinders, while maintaining the same amount of torque per cylinder.

Pluses and minuses to everything.

The 6G72 has a favorable bore to stroke ratio. The block is compact. The heads flow well even stock. The stock shortblock can make 600AWHP for years. In turbo form it made 100 HP a liter in 1990. The basic engine accessories such as the alternator, starter, a/c compressor last forever. The bores practically never wear due to high nickle content and a good rod ratio. They get reasonable if not very good fuel economy if driven properly. They have a unique sound that I personally think is great.

Some minor things I really love are how fast they heat up in the winter. The ones I have owned and maintenance have NEVER failed to startup if I didn't leave the damn lights on and kill the battery, regardless of the conditions.

They don't burn valves, they don't really blow up if you keep oil in them. I'm not sure what more you could want. What was a chevy shortblock (an engine that recently was voted #1 of all american v8s in hot rod mag for pretty much this century) making in 1990? 220 HP? Maybe 350 if you got the highest strung one in the zr1 vette.

I thought healthy dohc n/a's were around the 180(to the ground) mark? I've seen the 160 runs, for sure, but I don't think that's the norm...is it?

My old one dyno'd at 191whp, but I think the dyno was shady.

Eh, they say it's not a bad engine, but it was horrible to put it in the Eclipse. So... It shouldn't have made the list. Also disagree with the BMW V-12 engine. That engine is silky smooth and sounds amazing, and at the time, could produce up to 375hp, which was very good for an early 90's car.

Just another stupid list created by someone with an opinion. Nothing to see here...

Here is a 4g63 rod bearing next to a 6g72 rod bearing, for comparison.
