How many people have this on a road car?
I'm guessing new ecu and solenoid for it?
Does it destroy your turbo and can you have a switch to turn it on and off?

 

Much of this forum is US-based so this will be a tough answer. www.lancerregister.com might be able to get you better info on the Antilag.

All antilag systems are hard on the turbo but they're only active when launching, not between shifts. If you get a full-blown system like rally cars have then antilag is basically full-time when you're not on the throttle so that the turbo is always spooled. They're also replacing parts after and between races so wear and tear doesn't matter as long as it survives the race
