Don't see the point in paying out for an old technology turbo as don't want to he car to be laggy with all the power up top.
An EFR would require a twin scroll manifold and a down pipe mod which is no problem. My mapper suggested the new Garret G25 series turbo which would require modding my manifold or a replacement but I don't know anyone that has fitted one to know if they work with a YB. There may be other modern turbos that I could use ?
the questions are what turbo, what size, internal or external wastegate, and how far I can push the engine but keep it reliable.
Im looking to try and find a happy medium where I can run more power by changing turbos but keep it reliable and safe at the same time. I would rather get a smaller power gain but be safe than a big gain with the fear it's going to go bang at any point. If that makes sense.
