    So some guys in the car club around here jumped at the idea of building a turbo for my I4 engine. I know nothing about turbos of if this is even a good idea haha. Basically they are all car gurus and would love the chance to tinker with my I4. It would be a nice break working in my huge engine compartment comparedto their porches, auidis etc. Any input from you all is greatly appriciated

    If you want a turbo...SURE...

    Make sure they know what they are doing...and you learn as much as possible to avoid any issues...but there isn't a good reason NOT to that I can think of....

    Wouldnt mind one, I bought a 4 banger for a reason but IF these guys want to work on it for minimal cost, it starts looking a little bit better

    How many miles on your rig? No way I'd let anyone mod my engine under 100K..

    You're looking at a cost of around 3k with a similar setup as mine. The only problem with your truck is that you will have to get the header custom made.

    Good luck. I'm pondering the same... but have not found a manifold yet. I would read up & learn as much as you can, especially if this is a DD...

    For a DD, id definitely go with a SC. Thats coming from a guy with a turbo... There's just A LOT more to go wrong with a turbo.

    ya I decided against any type of thing until I pay my truck off, and probably never. If I ever wanted to I would get a project car.

    BTW, just for educational purposes what does forced induction do to gas mileage?

    Goes down the drain.


    Edit: To make more power, you need more fuel.

    Under normal driving conditions the loss of mpg will be minimal. Almost all off of the loss (maybe 1-2mpg) can be attributed to the parasitic drag of the supercharger. The remainder is due to weight, which wont be significant.

    Once you go above atmospheric pressure is when a significant loss of mileage will be seen. Like Dually mentioned, the more power you make, the more air is needed, and in turn more fuel is burned to keep the air/fuel ratio optimal.

    Exactly. My mpg actually improved at cruising speed (55mph@2000rpm) to right around 29-32mpg. But once I touch boost it goes way down. So overall my avg fuel milage goes way down due to being boost happy :D
