If you're looking for a turbo kit for your 1.6 a guy here near Montral sells one.
It's a top mount setup, ceramic coated log type manifold, GT25 turbo from a Mitsubishi, downpipe 2.5", lightweight flywheel, etc... Has to be tuned with a Megasquirt standalone unit he also sells in the kit.
Want the link?
Also, put LEDs in your front corner lights. I had exactly the same and because of the heat of the normal light bulb, the outside lens becomes yellow from the interior.
So with LEDs it wont generate any heat and youll save your corners.
Nice car though! Always a fan of a well built 99-00 proteg!
