You'll just be burying the needle on standard clocks mate. I robbed the taco out of the car ages ago (sorry) was a Pivot one and I'm pretty sure it was wired into the ecu?
I had an RSR one mate but it had a shit weld on it, build quality was second to none though. Really good quality. Have a Cusco now and it's spot on too!
I've bought expensive and I've bought cheap, absolutely no difference as far as I can tell apart from branding lol Found one on eBay with a fan and shroud for around £100 and it's been spot on!
