I've come up with two ideas for setting up my turbocharger. The first: move the battery to the back and put the turbocharger in its place; or I could have a custom intake manifold made and put it behind the motor (thus saving my headers). Which (if either) do you think would be best? If you don't like either one, please suggest something.

i dont know. but i was under the idea that most turbos go in the header area mounted to a manifold



Im a Xbox 360 fanboy...and damn proud of it!!

Usually they are, but I wanted to do something diff. so I wouldn't have to sacrifice my equal-length header.

Howdy, first post here.

The reason you should have your turbo right up close to the motor has to do with energy. The hotter the air in the turbo is.... the more energy it has.

Heat=energy. Energy=HP

The further away from the combustion chamber you have the turbo, the more heat is lost. The more heat you lose, the slower the air will move, and slower it will turn the turbine wheel of the turbocharger. In most cases in an engine heat it the enemy. However with a turbocharger, it is your friend. The faster your turbo spools up..the more energy (boost-airflow-pressure) it can create. You also want to avoid any "chambered" areas in your exhaust system. Thing like resonators and giant mufflers are counter productive to HP. They create larger areas for the exhaust to expand, and then cool. The new hot air enters behind.... and slams into a cold mass of air, restricting airflow. The freer flowing your exhaust the better you are. Ideally you would need a pipe dropping out the bottom of you manifold. That is not realistic though. There are so many "MYTHS" about teh concept of "backpressure" needed to get HP. It is BS. There is a concept called "scavaging" but is more involved than i will get into here.
As the air moves away from your engine, it cools and slows. So cut the equal length header and weld up an exhaust manifold with a flange for a turbo of appropriate size.
I have seen a twin turbo Corvette engine with the turbos right infront of the tail pipes.... but that was due to the confined space in the engine bay of the car.

Someone in my class made a good point about Isuzu turbos...they're almost as big as GM alternators.

The corvette probably had the STS system.
