Thanks Chappy, I have followed your post and love your fab work to the 914. I was a PO of a yellow 914 back in the day and always wanted to turbo it but a drunk driver total'd the car so I never got to doing it
Are you also using a MSD? I have the BTM model and was curious if you did the same.
For now I have the Garrett TO4E which should be good to push 12~14lbs, with the larger divided T4 flange this should help with lag and provide good response.
