Which actuator

Hi guys,

After a bit of help with my 20vt conversion specifically the turbo.

Currently fitting a KO3s to an AGU and the actuator appears to have seen better days so thought of replacing it whilst the engine is out of the car.

My question is which actuator should I go for? Forge seems to be a popular make but there's a fair few springs that can be bought to go with it which I don't quite get.

Any help/advice greatly received

Smudger.

Anyone??

Went for a Forge one. Straight swap.
