Folks, I have a 2011 Chevy Colorado with a 5 cyl 3.7 with 242 hp.


I love that engine!


I wonder if one would fit into a solstice?


Because....... I'd like a little more engine, but not a huge engine.


And .... I like to be a little different...........


Yep........ I love that 3.7 5-banger!!!:)

Should bolt right up the the trans, I'm sure even the input shaft is the same.

I roughed it out once and hood clearance is an issue but could be fix with an aftermarket hood or a scoop/cowl addition.

Through a turbo on it and youd have a crazy fun setup!

Hhmmmmm keep us posted, Sounds like a fun little build. I wouldn't mind doing this as well, still good on gas and have better hp, count me in.

That's pretty much the same direction I'm going, except I'm looking at Caddy 3.6L 6 cyl with a 6 speed trans.

Hi there!

I suspect it will fit. Like others said, you might even be able to keep your transmission. There are a thousand details that would be painful (which is normal for any engine swap) but I don't think there are any show stoppers.

Keep in mind that it is not a legal swap in the US, since you're putting a truck engine into a car. That's a no-no.

Well.......I'm no mechanic so all my ideas are just fantasy I guess.

My main fantasy has been for a small V-8, but eveyone said that couldn't happen. Or a small v-6.

who knows......... Maybe Mallet will some day offer a smaller engine swap than the Vette engine.

I just don't want THAT much engine.

it shouldn't matter whether its a truck or a car, its a light duty truck, as long as the engine had all factory emissions equipment and is from the same model year or newer, the govt shouldn't give him any trouble

Other than the fact that the law also prevents you from using a truck engine in an automobile.

If you don't have to worry about emissions laws, it'd be fine.

I realize it's all about "I have the only one like this", but you could spend a lot less money going with a stage IV from a turbo company if you have a 2.4L, or you if you have a 2.0L, you could spend about $5k and have almost 500hp..... Just a thought. You're talking about a V8, you could have almost as much hp with a stage IV kit on the 2.0L...... Just my :jm2c:

Dan,

Northstar is a DOHC 4-valve-per-cylinder V8 used by Cadillac. 4.6 liters. Many were 275HP, others were 300HP. The one in Dad's 2000 Eldorado ETC is 300HP and it runs great. It is a physically wide engine with very wide valve covers, so there may be a fitment issue.

If you can stuff it in, it would be pretty neat. Nearly 7000 RPM redline, all aluminum, etc. would make for a really fun sports car engine.

Sam, I wouldn't say anything in your sale thread, but when you post it here, it is fair game. That product is a worthless scam (by the manufacturer, not you) and will do nothing for a Kappa. And that has nothing to do with what the OP was after anyway, which is info on a specific engine transplant, not snake oil. Those piggy back units that plug in between the ECM and the harness and try to manipulate signals more often cause problems than not and almost never do any good. A simple tune will get whatever is there to be gained (unfortunately on an NA nothing near what Dan is after) without any fuss.

Dan - the Northstar had some issues but the design is nice - quite a few got shoehorned into Fieros. Beware the territory it takes up, as jwvess00 said - they are a WIDE engine across the top end and there may be fitment issues.

I agree with the guys that said that a GXP would suit your needs. Unfortunately, selling your NA and buying a GXP would probably get you more than a $2,000 differential unless you were very lucky indeed.

OTOH, thinking you could stick a different engine in your car for only $2,000 is naive in the extreme, so the GXP might still be your best bet as you'd probably spend that differential anyway if you embarked on a swap project.

Seems to me that the new Cadillac V6 with twin turbos and 420 HP would be a perfect engine for the Solstice

I would like to see if Mallet or whoever could offer something smaller, and cheaper.

Something around 3.5 to 4.0 ltr. would be nice I think.

Dan,

It's just my opinion, but there is absolutely no reason for any of the builders, or conversion specialists, to offer anything smaller than the LS series engines.

They have these LS series down pretty good by now, and the costs of doing a smaller engine are as high as they were initially for the LS series. There is not as big a market for the smaller engines, so there isn't much incentive to do the smaller ones.

As I say, it's just my opinion.
