Hi Craig,

I insist on the use of only Genuine Garret actuators as I find their operation superior to any of the alloy types.

I will discuss in detail with you what you actually want from the car when you arrive, but to make things more simple, for a car on greys and a T34 I use a -31 for up to a held 1.7 bar and a -34 for a held boost beyond 1.7 bar. I can supply either actuator if you don't wish to supply yourself, but please let me know in advance so I can check I have one or order one for you. Cheers!
