Eviloliv3 claimed: you cant acquire flywheel vs flywheel hp. to employ a B20 in an integra, you should utilize a LS manifold and exhaust, which flows a lot better than the inventory B20, thus providing extra ability. a stock b16 will make all around minimal 140s hp with scarcely in excess of 100 ft lbs.I purchased my MRS 3sgte again in 2020.
