no problem at all with cooling. the fan switch is wired thru the ecu and has never came on yet. i do have an overide switch wired in but again, never had to use it. To be honest i rushed mounting the fan to get it on the road with the plan of improving it in the winter.Ive done prob 500 miles in it now and the only snag ive had is lambda sensor positioning, the car ran great cold but as it got warm it was like running on choke, i removed lambda and had it resting in engine bay and the car ran near perfect like that, ive since looked at original mount and not much of the sensor was sitting in the gas flow,( the boss i made was to long!) ive now shortened the boss so more of the sensor sits in the exhaust. The car pulls really strong with this motor and if i'm really criticle, i'd say it could do with a higher final drive, its accelleration is great, but top speed seems to be about 90 on the sat nav without killing it.It cruises at 70-80 effortlessly and quietly. All told to get this power out of an a series engine would have cost a lot more, and reliability would become an issue. Its a pleasure to drive and has been well worth the effort
