So I’ve got a 1976 Datsun 280z and I’m doing a Rb25det swap and I want to have a top mount turbo because I want to see it more clearly and a bit of an upgrade To get more power around 400 hp and if I’m right I think I’d need a new ecu and wiring harness I’ve got no clue what’s very reliable and simple to complete as a project so if anyone has the knowledge of all the parts I’d need to do this and it would be very appreciated if someone could help out thank you for your time.
