Bullet proof a mate had one for 4 years, in that time it was thrashed non stop without failure.
Std turbo only good for 1.2bar max or it snaps.
Oh with just decat, exhaust, filter and uprated fuel pump it set a 13.9 sec 1/4 the boost controller was set to 1.2bar. Not bad for a car weighing 1400+kg.
