Finally got back to work today, first day at a new dealership (sales). Chevy dealership. So in an effort to get a little more familiar with the Chevy lineup (my previous car sales exp. was with Toyota...please forgive me!) I was reading the HHR brochure. They have a HHR SS, with turbo and a Getrag 5-speed. 2.0 Ecotech Turbo (not supercharged like the Cobalt SS was, but same engine) and it says right in the brochure that it has a Getrag 5-speed.

Who knows anything about this Getrag 5-speed? And does this not sound like a sweet swap platform?

The Ecotec is a nice install, and I don't see why the turbo version would be any different. The electronics of course will be the bigger issue.

As for the Gehtrag I thought all the 5 speed Gehtrags bolt up.

the Solstice GXP/ Sky Redline has the Turbo 2.0 ecotec but the HHR is FWD so it might be a better complete drivetrain swap for a Fiero?

Different bellhousing, largely the same Getrag. Unless I have been misinformed, there are some minor differences (I would imagine that the Turbo Ecotec uses the same trans as the Supercharged one)

Putting that driveline in a Fiero would be tons of fun though

Straight Ecotecs have been done, so I would fine those guys (If you search in Technical for Ecotec, you should fine at least one or two swap threads) and ask them. You'd have to fab up the plumbing for the turbo though I'm sure.

Yep, the bell housing is a different bolt pattern, but do the bell housing cases off the new and old Getrags fit?

Why? Get the engine with it's transmission. The gear ratios are better matched (hopefully), but primarily because you have a new tranny instead of a 20 year old one.

Not everyone wants an Ecotec. I do, but thats also because its the cheapest way to get VVT and spin 10,000 RPMs.

I'm sure the 350 and L67 tuners are going to love these trannies since they are not only far stronger and have better gearing, but Truetracs and other LSD's fit the tranny while the only LSDs for our trannies are crappy clutch type LSDs.

(I dont mean to knock anyone's product with that statement, I simply mean that clutches wear out and springs break. Torsen-type differentials dont.)

The LSD's are junk, at least in FWD applications. The gearing is MUCH worse than the fiero transmissions, even to the point that the strength is not worth the upgrade.

The cobalt owners are all complaining about gear ratios and they are shifting at 7500rpms, a 3800 shifts just before 6.

i doubt the L67 guys are gonna care because it doesn't bolt up

Wasn't the Ecotec SuperCharged (from the Cobalt SS) discontiuned in 2007?

A 3800 also has loads more torque below the Ecotec torque curve, so you dont have to rev as high. Last I checked there is only one FWD Fiero and it has a sub-2 liter Saturn engine and transmission in it, so the point about a FWD application is fairly moot for our discussion, nevermind the Truetracs are hardly junk.

I was unaware of how bad the gearset ratios are, but I was interested in a custom performance set anyway.

The Supercharged Cobalt SS was discontinued because it is getting the same drivetrain
as the HHR SS in 2008.

The Ecotec SC/Turbo issue aside, as I think many of like that engine...I was more interested in the fact that there is a new Getrag 5 speed. Perhaps not new as in revolutionary, but at least it isn't 20 years old. With that Ecotech as offered with that Getrag 5 speed in the HHR Turbo setup...well, it just jumped out at me as a great swap. But if nothing else, if we have a Getrag 5 speed in a brand new Chevy then that can't exactly be bad news for us, right?

I am curious what that swap would be like. Being those engines are direct injected, would that add any difficulty or just some more wires to splice.

The HHRs are all drive by wire. Everything is controlled by the ECM. I suspect that there may be potential for wiring nightmares getting the engine running correctly once swapped into the Fiero. I have a 2.4L HHR and performance is at high rpms which is nice when you start running 4-6000 rpm. You need to be a computer "geek" to maintain the car.

You'll need a high pressure fuel system, for one thing. The Fiero 4 cylinder uses 5 psi (approx.) The V6 uses about 45 psi. New Direct Injection engines run about 1750 psi.

I'm pretty sure the new DI gasoline engines operate like diesels and have a mechanical pump mounted on the engine.
