Common question Posted by Ari [Email] ![]() ![]() In Reply to: Convert to Turbo, saablover ![]() |
With lots of answers. It all depends on what you want.
If you want the power, driveability, and reliability of a stock turbo car, then the most economic way is to sell your car and buy a car that came from the factory with a turbo.
The turbo system includes the turbo, exhaust and inlet plumbing, intercooler, different pistons, different ECU and fuel system, the addition of the APC and wastegate actuators, etc.
If you're looking for just a little extra power, then you can go the Low Pressure Turbo route, which can leave the pistons alone, and no APC. Possibly even give up the intercooler, but you should still expect some fuel system changes.
My stock answer is - if you have to ask, you shouldn't do it. Doing a decent turbo installation takes a lot of experience and system knowledge. No offense, but if you're asking the question, then you probably don't have that experience and knowledge. Many of the folks that say 'that's easy!' have done it a few times, and know the systems inside and out. That's not exactly true - I've seen some horrific turbo installs where the power is not much greater, but the drivability sucks. I never see the ones that grenade the engine in the first week.
HOWEVER - If you're looking for a project, and want to just learn, then it's doable. I'd assume it's a car you don't care much about. As a learning tool, there's nothing like doing to find out a lot.
But - if you've got a nice car, or at least a decent one, and you're just looking for a cheap and quick way to make the car faster, then adding a turbo isn't the way. The strength and reliability of the Saab turbo comes from the fact that it's an engineered-in system - not the bolt-on quickies that gave turbos such a bad name (GM and Ford) in the late 70's - early 80's. That engineering-in means that a quick swap of a few parts won't cut it.
