It has a roughly 50% chance of being good. If it is bad it has become very difficult to find good used ones. I have 10 “extra” turbo systems and of those only 3 had good ones. I have since sold all of those good ones. I will be talking to these people soon and hope to have a sample in the next couple weeks.
Also, welcome to the Jetfire community. We are a small group of very rare car owners. From what I know of your car it looks to be a really good one. I supplied them the original back seat cover to use for material to fix the fronts.
I just got an email that they should have some parts made next week. I am not sure if that is a test part or the actual finished product but we will see. At lest it is still moving along. Just hope nothing happens to my NOS one I sent them.
