@ Sleeper! I blame games like GranTurismo for this, it gives the impression you can just throw a turbo on any engine and it works. Are you still up for writing a sticky post on this subject for us that we can throw into our "adding a turbo thread" to point people towards. We have to educate the masses!
Do that to a Suzuki Wagon R and you will notice nothing. Not a thing. You could fit Brembo 14'' disks with some propper slammed adjustable coil overs, some super soft continentals and you will notice nothing.
Stage 2, which consists of a Bosche VE fuel pump, a bigger hybrid turbo and forged internals. As my car doesn't have an ECU, so no remap. Then suspension and brakes.
