2.0 EcoTec in a GBody?

[drogg1]

That's where I'm saying that the 455 mentioned earlier, although much larger in mass, will still make cheaper performance even in consideration of its weight than the ecotec performing equivalently in a car. Thus it is less cost efficient not physically efficient to use the ecotec.

I think a cool Ecotec swap would be into a Chevette. :idea:

Yea or maybe a turbo version in a Fiero.

Exactly. Its not the actual displacement. Its runner, bore, stroke, valve size. Thats why euro V12s are still only 5-6liters. They have rather small bores and strokes, same with F1 etc

I say if someone has the funds and the interest, then do it :!: I think it would awesome That engine probably weighs a 1/4 the weight of a V8 engine. Upgrade the turbo and tune that little EcoTech. Those bottom ends are completely forged and GM states that they will handle something like 800hp on the bottom end 😱 They are awesome little machines! I drove a Soltice GXP (260hp/260ft.lbs 2.0L EcoTech) and it was amazing, the amount of power it produced.

It wouldn't accelerate all that awesome in a heavier gbody. Under boost it will use as much fuel as a v8. The Solstice weights 2,860 my 442 weighed 3,840. The result would work especially if you can get a 6 speed to fit but it might not be a particularly exciting or fuel efficient ride.

How about an LS engine... Modern and meant to be in a big car, not a little econo car. Yeah a turbo engine is always going to put out a better hp/liter ratio than any naturally aspirated engine. At 15 psi you've literally doubled the density of the atmosphere at sea level, so a 2.0 liter with on 15 psi (theoretically) is packing in the same amount of air and fuel as a 4.0 (assuming 100% VE), and it doubles every 15 psi (not in reality because of heat and mechanical losses, etc. but in theory). Plus with the ecotec add in the 40+ years of advances in technology over the SBC and the old BOP engines, 2 more valves per cylinder, variable valve timing, overhead cams, computer controlled coil on plug ignition, and multiport fuel injection... It damn well better be more efficient than a carbureted two valve engine with a design from the early 50's to 60's. :lol:

I mean I'm sure the ecotec is impressive, but it would be a lot less impressive in a mid size G body than it is in a sub compact. Even if you ported the hell out of it, and boosted it to the levels you mentioned in that Nova... I'm sure it would be fast but it probably wouldn't be fun to drive. I'd be willing to be that Nova is a laggy horrible car to drive unless you launch it hard... Turbo 4's with a lot of HP usually are all top end and no grunt.

I'm LMAO!
You guys are so funny! You guys say "G-body cars are too heavy for that engine" when the 2.0l Buick GS is over 3,700#!

When you have peak torque at 2400, and hp at what was it, 5300? That's not "peaky" at all. That's stump-pulling power. I guarantee you the curve is VERY wide.

OK heres the question: "Would you rather have the 135hp 301 Pontiac engine, or the 2.0l turbo in your G-body?" :?: (I know, the answer is neither)

My buddies all gathered around a pickup at Car Craft last year, for like 45 minutes. This guy had stuffed a Detroit diesel semi-truck engine in there. It was kinda ratty, but so different that everyone wanted to check it out. $50,000-100,000 cars galore, and they were hanging around this ratty one ton pickup.

(I really like the Fiero idea)

It wont be a race car but it will pull it just fine. That's what I was reffering to about the hp numbers. You're right it wont be all that exciting but more than half the v8's on this sight aren't exciting. However with either engine, that can be changed.

And at 2 tons + with driver, your 442 is a pig for a g-body. Both my Malibus were 3200.

Small engines always have to work harder than a larger engine to make the same power. That is why the Ecotech has a forged bottom end, it needs it to survive since it works harder. A V8 doesn't have to work as hard to make the same power so it can get away with using cheaper parts and living just as long if not longer at the same power level.

Besides power curves being broad or narrow, there is also how even they are. N/A engines have more even power curves while turbo engines have uneven curves due to the turbo not running all of the time. Peak HP and torque numbers don't really mean much by themselves. A graph showing the power curves shows the whole story. Here is an exaggerated example: Redneck is a V8, Ricer is a turbo 4 banger. Both have the same max HP in cars of the same weight.

As you can see, Redneck has a more even curve so his car will be faster and have better control, aka driveability than Ricer's.
