I guess Miata is the new 34 Ford.

I fail to see the point. It's not a great engine, is it? Doesn't seem it'd be worth the effort.

 

This is from a cobalt SS/TC? From what I've heard, those engines are about on par with the MZR disi. They respond well to mods and love e85. I'm surprised the numbers are so low if that's the engine I'm thinking of.

 

FWIW those were 2.0L engines. This is a 2.4, so should be the engine that's been in every Malibu, Pontiac G6, up-trim Cobalts, etc. from early 2000's to like 2012 ish.

 

its always fun to see new swaps.
I guess the miata is becoming the new ford. And I'm okay with that lol

 

I know nothing about the ecotec engines but what is the deal with the dyno sheet? looks like turbo torque but images of the engine bay looks like it is naturally aspirated?

Wow, all kinds of new swaps coming out this year!

 

I'd still rather go k swap.

 

I agree. With the amount of aftermarket support for the K-series it would be difficult not to choose it for a swap option. Now when someone comes up with an Ecoboost 4 or V6 swap...

 

I think this is pretty damn sweet. Those ecotec engines are cheap, as reliable as a BP, and make lots more power. I dont know anything else about the swap, like weight, modifications required (probably oil pan at least), or if the steering rack is moved and all that jazz. At first glance it looks neat though, and I'm glad to see more stuff popping up.

 

Yes, but you are the only one that actually brought one to market quickly and with a running proof of concept car that works on the track.

 

Curious swap. Since the torque curve is fairly modest, I'd expect it to be notably lighter to make it worthwhile.

 

Thank you.

It's impossible to beat the K series for N/A performance potential, but options are always a good thing for people. We just happen to be a little partial to our product

 

Yeah, i don't think any four cyl is going to beat the K motor in a Miata. But i wouldn't discredit the ecotech either, they have been proven to make upwards of 1400 hp in race trim.

 

I'm very surprised it fits under the hood. Thats a pretty tall engine. Bottom end should be able to take 400hp depending on the year of the block. I would rather have the LNF though. 400/400 on e85 with the stock turbo and bolt ons with a really good tune, but they're not as cheap to get. I still think the K24 is the leading non-mazda 4 cylinder swap. And that someone really should just start selling an FE3 swap kit to fill the same nich that the ecotec swap is filling but with an engine that has the exhaust on the correct side and no drive by wire throttle.

 

Cool and all but show me anything an Ecotec does that a K does not do as well or better.

The K allows for minimal driveline changes rather than a whole new transmission/PPF, etc solution being required.

The K is pretty light.

The K has as much displacement.

The K is widely available.

The K has lots of aftermarket.

Didn't the early Ecotecs like the one in my truck puke rods at about 280WHP? I can go with a BP for that.

Edit: The K also has this thing that's helpful when racing: top end. 4 cylinders in hi-po applications running out of breath at 6500 is pathetic. It's 2014.

 

All the 2.2s the later 2.4s gm sets the safe limit at 250hp with nitrous. And safe rev limit with the stock balance shafts is 7k. very early 2.2s like 2002 and older have timing chain problems. The one good thing with them is that GM has a build book that pretty much tells you what you need to replace on them for anything between track reliable 250hp to drag strip reliable 1500hp.

 

I didn't see kit mentioned anywhere, just that they did the swap. Did I miss something.

 

The deal is that particular one is 2.4 and vvt. It's also designed to haul around a sedan. The newest ones are 2.5vvt and direct injected. They are rated at 202hp and 191tq have piston squirters and a forged crank. Tune and header/intake and I wouldn't be surprised to see 220hp.

Ecotecs can be run by the stock gm computer that is easily tuned by hptuners or efilive. I happen to have hptuners because I've had several gm vehicles and I've been considering this swap for a couple years.

I'm buying another daily next year and this will be my project.

 

I've driven that car and can report that it is currently normally aspirated and a bit of a torque monster. The current NB only version retains the subframe and does not relocate the steering rack. The oil pan on the prototype precludes using power steering. Everything from the clutch back is stock power train and it uses a custom flywheel and interface plate.

There is a plan to produce a swap kit once all of the kinks are worked out.

Last I heard the prototype had lapped Shannonville full track at 2:00.37 so it's no slo-poke.

MTMotorsport is fairly well known in the Miata circles in Toronto and has some seriously hot turbo cars running the local tracks.
