I just bought a rebuilt (in the UK) TD05H 20g. It has a large Forge w/g act. fitted. The seller supplied the two springs that came with actuator (as supplied by Forge, as part of the whole product).

Presumably (hopefully) one is the same/similar strength to Subaru's own OEM TD05H 16g actuator... whilst the other spring is a stronger one (to run very high boost e.g. say, 1.7+ bar, or whatever)???

Does anyone know (and I'm guessing it's a question for the specialists/tuners?) what the actual bar/psi rating of the Forge springs are? (it doesn't specify on Forge's website! ).

Hi joz found this tells you what pressure forge springs are but not how to identify them plus dont think they are uk ones,

also found this if they are the same as the T2's or the T3's, what colors are the springs?,

Well the spring that's not already in the actuator is defo the more tapered "T3" type. But it's not coloured! It's just unpainted (or uncovered) bare metal... so have no idea what rating it's supposed to be(?).

As for the spring inside the act., I'll have to unscrew all the little Allen grub screws to remove the act. cover...
