First three things we'd modify
1: Turbo-back exhaust
The downpipe and cat on this car are serious backpressure hogs, and the rest of the exhaust is a carryover from the much less powerful MP3. Uncorking the exhaust flow will make power, and make room for more boost.
2: Front-mount intercooler
The intercooler, carried over from the European Proteg turbodiesel, is tiny and half blocked by A/C brackets. Removing it would open up an easy path for plumbing to reach a nice, big front-mount.
3: Boost controller
Turning up the boost without the first two mods is virtually pointless. With the clogs removed, however, power should be easy. Just remember: Stock output was kept low to protect the transmission. Avoid clutch dumps and hard acceleration on broken pavement.
