@Pᴀᴜʟsᴛᴇʀ2 & @BobCross Oh, ok. So a turbocharger would be better than a supercharger for my car? I am willing to spend more on the car than what it's worth. I bought it for $300 and then it is now worth $6,800

I have put a lot into the car to make it worth more. Including a new air system, audio system, transmission, gears, and of course lots and lots of smaller stuff.

So I wouldn't mind custom at this point. I just don't want to ruin the engine. I just want to make it as powerful as it can possibly be without hurting the engine.

Do any of you have shop recommendations for places that could do this kind of work? I'm in the Utah Salt Lake City area. So anywhere around there or within 20 miles will work.

@ScientistSmithYT - I get the "want" to make the car as powerful as you can ... however, the car you're starting with wasn't designed to be more powerful. If you want to add a turbo to the car, about 7psi boost is about all you'd want to run ... that'll get you another 50 hp at most. It's not going to be a barn stormer by any means. If you want to run most boost, you're going to need to rebuild the bottom end of the engine (think a LOT more $$$) to make it stay together.

Plus, you state your car is worth $6800 ... maybe that's how much you have in your car, but that really doesn't mean it's worth that much. I don't think your car cost $6800 new.

@ScientistSmithYT While a project like that is one that is popular with new mechanics and apprentices, who may be able to get hold of parts for free or very low cost through their shop, and who do t to learn, it is the most expensive way to get a more powerful car

As Paulster2 said, it's not just the turbo, or even just the engine block, the transmission isn't designed for higher power, so that may also need to be replaced, and then you get to brakes and wheels

Most folks choose cars that have a strong existing user base for upgrades if they want to do this, with known upgrade paths, components etc

Your Accent will not be upgradeable in the way you hope - to get much faster acceleration, as well as a turbo, you'll need a new engine, transmission, and maybe suspension, chassis and brakes...

@Pᴀᴜʟsᴛᴇʀ2 another interesting option would be to sell the current car and pick up a used car with an OEM turbo. That would likely be the most economical and satisfying path to turbo power.

It’s also a lot easier to tweak a car that starts with a turbo rather than trying to build up a custom system.

My 2004 WRX has been a great car to work on!
