yea its a DOHC, all 3000gts were dohc until 97 when teh base models started to come with sohc’s…TT conversions can be had for anywhere between 1200 and 3000. Everything bolts right up from a VR-4 and theres alot of people who run the stock 10:1 compression with great success at lower boost. This is a steal in that condtion and with such low miles. i paid 4 grand for my 94 with 127k and its not nearly as nice as this!
