Black box....dont bother dude, if you can tune on e85 do it...if not just save your money for blow and hookers...it will be more fun

I wouldn't hesitate to fit an adjustable exhaust cam pulley on an RB25 if doing the belt etc .

Another option exists if you are going with a T4 flanged manifold and that's the twin scroll IW EFR turbos . All the blurb I read suggests that those lightweight Gamma Ti turbines make a significant difference because they have less mass to accelerate .

If you went with an IW TS T4 flanged one you eliminate the need for external gates so less bulk cost etc . These EFRs have long turbine housings compared to most turbos but they make things easier in other ways .

Just a though cheers A .
