Genuine and unused adjustable Holset turbo 18psi wastegate actuator


As title really. Rather than one of these junk leaky Chinese/Mamba/Whatever universal wastegate actuators, use one of these genuine Holset ones I’ve modified myself to allow for adjustable length which makes them pretty much universal fitment.


I’ve used these actuators on various Garrett and BorgWarner turbos, as well as Holsets of course.


They have the usual Garrett 2 nut fitment (35mm centre to centre) and an adjustable rod length of around 150-190mm (to centre of turnbuckle eyelet).


The spring has a cracking pressure of 18psi as tested using a Mitivac, and unlike almost all aftermarket actuators, doesn’t leak at all, completely air tight.
