Chevette Ideas?

[roosterk0031]

Saturn sky redline engine and tranny for a sleeper. A S-10 2.2 with 5 spd would be economical.

I agree that 100 HP is enough, but the Chevette has about half of that at best. Most Dyno test to well under 50 at the wheels, and about 40-50 at the crank.

A Skyline engine/transmission would be awesome. The s10 drivetrain is a good choice too. I'll look into that one.

That's a great way to put it.

1989 Buick Park Ave -3.8L 165hp V6, 3339lbs, slush box. 19 mpg city - 30mpg highway, with a cd=.40

Lets see.

With a manual trans. fuel injection and a 100 additional horsepower in a car that weighs 1300 lb. less than what the v6 came out of, with nearly a identical coefficient of drag ,it could easily be expected to deliver high mpgs.

A big plus is that nearly all GM products (engines and transmissions ) are interchangeable.

A GM 60 degree V6 is a direct drop in.

The 3.8 however is a 90 degree. It would require a little more work. (exhaust)


This is the way I see it.


1980's Chevette = dirt cheap

1990's GM V6 = cheap

Having a inexpensive classic 1980's eco box that hauls a$$ and gets great mpg

= Priceless

considering there is atleast 5 very different bellhousing patterns that gm has used over the years in north america; just swaping the 3.8l would be a problem(bop or scb) and that the chevette uses really wierd engines to begin with.

best bet for a 3.8l swap would be to get a wrecked f-body.(only modern fuel injected rwd 3.8l)

Yes, yes.

I was just generalizing for comparison.

Just incase you questioned the anything will fit in there

427 Big block. Go big or go home
Ok not sure you could get any descent MPG out of it but it would not be to slow.

I think you are in the wrong forum, you'll be lucky to have half a tank left after driving home from the gas station! That's would be a scary car to drive, probably have to replace the rear tires every month, probably brakes them loose in top gear at highway speed. I still think a turbo v8 Fiero would be funner to drive, at least it would get some traction and handle and not all smoking tires. The Vega was designed for a Wankel engine, which GM never got working. I can hear the owner. I said 427 Corvette, not Chevette!

What engine/transmission swap ideas do you have? Or rear end swaps? Obviously a boat tail or a kammback would work out well too, a grille block, a lower front valence, pizza pans. But what could be done to the drivetrain? I love saving gas but I need to move faster. If I found one with a T-5 that would be nice of course but they're not too common.

If your faster means cruise velocity rather than acceleration,consider reducing your road horsepower requirement first, with aero and rolling resistance.Then if unsatisfied,go after the power train.
My standard-power, streamlined pickup has better HWY mpg than early,lighter,smaller diesels.

The 1.4L turbocharged engine from the Cruze might be nice too.

A 100 hp engine is quite enough to cruse at 80 mph in my saturn, in fact I have 180 degree air going in so its probably only 80 hp.

Musta been a diesel Tempo- sheesh.
