Your Swift-Clone Might Have a Hemi


From 1985 to 1986 the engine used a hemispherical head carbureted design.
Hemispherical chambers have never been MOPAR only - they only have a trademark on the Hemi name. It's just kind of funny to find it in the 3-banger G10.

I wonder if I could find one and swap it into the Metro? Hmmm...

I can see the commerical now...

"yeah, it's a Hemi."

*putt putt putt putt*

That's hilarious! lol :D

Oh man, that's wicked, these folks should get a HEMI badge for their cars, :p

Anyway, I wonder if they're more efficient (fuel injection issues aside)...if so they might be a fitting swap to a newer FI swift-clone.

The wikipedia article mentioned something about heat...um...


Later, as fuel injection was mandated, the cylinder head was redesigned to add the additional cooling required.
Additional cooling, huh? Hemi-head = built in warm air intake? Again...hmmmm...

SVOboy 06-12-2006 12:07 PM

I dunno what that means, but mehbe it doesn't dissipate heat quickly enough for an efficient air-fuel charge to be burned, :p

95metro 06-12-2006 12:09 PM

Unless it's too much heat in the cylinder and causes detonation. :confused: There's got to be some crazy-man out there who's tried it.

SVOboy 06-12-2006 12:11 PM

Yeah, I'm guessing that's what they mean by cooling, the hemispherical design was too prone to detonation or something such.

I can't think of another reason they'd design such an oddball engine and only use it in one model for two years, but I guess US engineering doesn't make sense a lot of times.

95metro 06-12-2006 12:15 PM

Sure, but isn't it a Japanese engine? Or are you referring to carb vehicles going AWOL?

SVOboy 06-12-2006 12:18 PM

I'm saying that US manufacturers will do silly things like run an engine design for only two years.

But Geo is japanese stuff, though I dunno how much was the designers' decision and how much was the US office's. I dunno, I'll blame it on a detonation issue that seems implied in the "cooling" statement.

95metro 06-12-2006 12:20 PM

I agree. Detonation probably was the issue. So any FE gains would probably be offset by having to retard the timing or lowering compression by other means. It would still be an interesting experiment...and just having the "Hemi" claim would really turn heads...:D

SVOboy 06-12-2006 12:21 PM

True, I wonder if a 5.7L HEMI would fit in there...
