The factory turbo on our Mitsubishi Eclipse can handle up to 16 psi of boost with the factory fuel pump. To get more power to the wheels, we want to increase the boost level from the factory 11 psi setting to about 15 psi. To do this, we're going to install a mechanical boost controller which will allow us to adjust boost levels.

NOTE: Before you install your boost conroller, we recommend installing an aftermarket boost gauge. The factory boost gauge on the Mitsubishi Eclipse (as well as the Eagle Talon and Plymouth Laser) are known to be very inaccurate. Severe engine damage is often the result of an inaccurate boost reading.

Perform this installation at your own risk. We do not assume any responsibility whatsoever for any damages of any kind resulting from any information printed in this article. This article was created as a supplementary resource and should not be used as the lone source of information on this topic. We recommend that you seek the advice of a trained professional. This is simply a guide to show users how we accomplished our own installations for our Project Car.

A few tips for installation:
1. Make sure the vehicle has had sufficient time to cool down.
2. Gather all tools needed beforehand.
3. Buy a couple of extra hose clamps and barbed fittings in case you break or lose the originals.

Parts Installed:

  • Buschur Racing Mechanical Boost Controller (MachV.com)

  •  Step 1:
    Locate the rubber hoses connected to the top of the air filter canister (labeled "air can" in the photo) near the intercooler piping. Disconnect these two hoses from the fitting. If you follow these two lines, you'll notice that one connects to the base of the air canister and the other connects to the wastegate on the turbo just below the exhaust manifold. Disconnect both of these and discard the two hoses.
