I work with a guy that used to be an electrical engineer. I told him about this turbo and he came up with a real simple circuit to control a servo with a pwm signal and move it based on voltage (or map pressure). He also said that he can set endpoints and control the hold voltage or map signal. My turbo should be here today so we are going to tear into the stepper motor that controls the VGT and will see what kind of input it requres. We might just switch to running it with a servo and call it a day though.
Well, I got a little work done today. Got the old engine out, new one in, intercooler mounted (and stealthed) everything is wired up and ready to go. Just have to make some new charge pipes, new wastegate dump tube and a couple other little house keeping things. Right now I only have the little .42/.48 saab turbo on in while I break it in and until I can get some time to build a manifold for the HolSlut. It has been over a year sense I drove this whore and I want to get out and drive it. Hoping to be driving this thing to lunch tomorrow. Enjoy.
Looks like a case of now you see it!
Now you dont!
