Yes it's old technology but at less than a third of the cost of a new TVS90, a M62 from a Cobalt SS works pretty good on a Gen1 MINI. Is it better than a TVS900? Hell no, of course not. Is it better than a M45, oh hell yes from my own experience. The M45 pushes 0.74 liters per revolution where the M62 is 1.02 and the TVS900 is 0.9 liters. I have been running a M62 for over a year with zero problems. Started out with a 66 mm pulley and then went down to a 62 mm. There is a 58,4 mm ready to go on but that is topic for another thread. I have a DIY thread on a FB page. Also sold 3 units that were shipped over to Europe and 1320 will be tuning one of them. With the electric water pump and paying a welder I have $900 in my kit.
