Turbo on a 4th Gen

Remember that a turbocharger is not the only component needed when putting together a turbo kit. In addition to all of the parts that could be used from the Eclipse, you will also need a custom exhaust manifold, and those can get expensive.

Also, if you go look on Ebay, there are plenty of turbos around that price, or even cheaper. I believe that the one your friend is selling has an internal wastegate. If you're looking to run higher levels of boost in the future, then you'll want a seperate, external wastegate.

One more thing... Depending on how much mileage is on your engine, it may not be such a good idea to add a turbo. Our F22a's have fairly low compression already, but you may want to investigate some low compression pistons and rods.

I was planning on doing a turbo system for my F22a4, but I just decided to get an H22 instead, since the cost differential is only a bit more than doing a quality job on a turbo kit.
