Used set of 52mm Blitz DC Guages available in Boost, Oil P, and Temp complete with ECU and senders £200+P&P.
An electronic stepper motor controls the needle making the gauges very stable, extremely accurate, and capable of many powerful features.
Additionally, a ‘Live unit’ contains the control electronics for each of the gauges and can be tucked away behind the dash board. A live unit is required to power all the gauges and can operate up to 3 gauges. Each gauge is therefore very thin (24mm deep) and easy to mount.
PS. I will give NOS first refusal as I know he was looking for some.
