from what i understand you would have to get your compression way down,ie different pistons,to turbo your current motor.

Another option that may be cheaper and easier than trying to get ahold of these late model GM engines and transmissions, plus the ECU/PCMs from those particular vehicles to make it all run is to go with a 4G63T. That is the turbo 2.0 from all the DSM cars from like 90-99. That would be the Mistubishi Eclipse, Eagle Talon, Plymouth Laser models. Then you get a manual transmission from a Mitsubishi Mighty Max pickup, 2 or 4 wheel drive. The 4G63T will bolt right up to the transmission, all you have to do is make motor mounts and run the engine harness and mount the ECU. The best part is that junkyards everywhere are full of these engines and transmissions, and you can go with a 2wd or 4wd option.

The GM stuff can get tricky. For examply, the LSJ (2.0 supercharged) and LNF (2.0 turbo) cars use a PCM (powertrain control module) that runs the powertrain. The rest of the car runs off a different computer. Some of the other models, like the basic Cobalt with the 2.2 use an ECU (electronic control unit) that runs everything. I don't know what the Canyon/Colorado use, but I'm guessing its an ECU that runs the whole truck.

This could cause problems. For example, if you use a LSJ or LNF engine, with a transmission from a different vehicle like a Colorado or Solctice, the PCM for the engine thinks its also supposed to be controlling a transmission. However, the transmission from the truck is designed to run with a different computer, so you have to set up two different computers. One for the Engine from a car like a Cobalt SS/SC, and the other for the transmission, like from the Colorado. You could end up with both computers screwing with you because they think something is wrong with them. This is probably only a big issue on Automatic transmissions. The manual transmissions may be much simpler and not require a computer to control it.

I don't know for a fact that this could be an issue, you may even be able to re-tune the computers. I do know that the PCM that is in the 05-07 Cobalt SS supercharged is a very finicky computer. It can only be read/tuned with a computer program call HP Tuners. That software happens to cost about $500! Without it, you can't so much as change the fuel injector size. It gets expensive and complitcated REALLY fast. The PCM is literally completely locked without the software. About all you can do is change the air intake and do some mild exhaust work.

Just something to think about. I'm all about GM, I've thought about building a stroker turbo motor for my SS/SC and putting my engine in my LUV also. But those Mitsubishi engines are pretty stout, and cheap. And MUCH, MUCH less complicated.

But to answer the original question, YES it will be FAST!

Good luck.
