We recently installed shimless buckets, 280 cams, coated downpipe, pushlock fittings, mounted FJO box, fixed coolant leaks, powder coated blowoff valves and tuned Daniel's MKIV Supra
Even with two people in the trunk the car spun. The injectors are maxxed out at this point so we didnt take strapping the car any further. Boost was roughly at 28lbs. A lot more left in it with bigger injectors
