Super engines got camshafts with brand new specs as well as plastic consumption manifold along with TGV shutoffs inside. The FA20 DIT possesses Double Scroll turbocharger Garrett MGT2259S, which produces pressure 1.1 bar (1.5 pub in over-boost setting) and creates 272 hp at 5600 rpm and also 258 lb-ft of twist.
