I would like to get advices from people who have experience on turbochargers. I have got gt2876r (gt25/40r) dual ball bearing turbocharger with a/r 0.82. I would like to know, When I can expect to see full boost (20-22psi)? Will it be very laggy? How much boost i will have to push, to see such power? The car is for everyday use, and I want to reach 370bhp limit. Motor is fully standart. 3" straight exhaust, rs500 IC with 70mm tubing, 3bar map sensor, grey injectors (i also have light blue ones).. Please give me advices. thanks.
