I got a little excited to score 4 inspected denso 195500-2010 for $100, the guy threw in the MSD Miata boost retard box. It is NIB but I know now that I don't need it for this build. I have another car that I am also planning to turbo charge and will run lower boost. I will probably use it for that car in combination with a FMU. The other turbo build is a 4 cylinder but 2.4L and 160 hp so I only need 6 psi to make it really really fun. Probably going to get a SR20 turbo for it.
