I ran synthetic oils and my turbos lasted 130k miles before I rebuilt it to upgrade the turbos.
Batman I believe I met you before, had no idea your NSX was S/C. I came in my RX8 at Pacific Commons once, with my buddy in a blue evo8 but he didnt want to stay so we left. Im leaning towards NSX but its going to be a lot of money to get power out of it of course. As a daily I think the NSX would be best no contest. Although FD reliability has gotten way easier to achieve over the years.
I owed a really nice Rx-2 with a street ported 12a. Rotary engines are a nightmare in terms of reliability. My last girlfriend had an Rx-8 and it drank oil like crazy and got 18mpg
I get 19 mpg roughly in my 8, Mine hardly drinks oil. Depends how much my foot is on the floor.
