I've had a demon sport one, a tial and a fake turbosmart, couldnt tell the difference between the tial and demosport. Fake didnt work at all. Id go for a demonsport one mate lap the valve and you'll be laughing with a spare £150
I took the idle control valve off and taped a thread in the inlet. Make sure you use lots of tallow to catch the swarf otherwise take the inlet off after. Then a bit of loctite and thread the bolt back in
Was kind of second hand but jdm ep. I looked elsewhere before and asked turbosmart to verify the seller, they are happy to do that. Just trusted the second hand one
