Okay, after much debating and struggling with the concept, I've decided I want to try my hand at boosting my D15B7. Under the impression that I don't go above 10 psi of boost, I'd like to have a semi-reliable setup that can be driven. As for the engine, it's in good condition. 104k miles on it, and it has a new HG, timing belt, waterpump, new main seals, clutch, radiator, and all the other happy horseshit. I have a few questions for the boost gurus on here (mainly psol, hotrex, calesta): I'm not imcompetent, and know my way around a turbo setup, and can wrench with the best of them, but heres the stuff I'd like to know and get some feedback on. -Injectors? 450 DSMs too much? Under the impression I'm gonna change out my pump, want to know what size will be good. -Fuel management. Heard different things about FMU's and fuel regs. FMU? AFC? I want to try and stay away from expensive standalones and piggbacks. Dyno time ain't cheap. -Manifold. Cast? (assuming I can find a D-series ni-cast manny) Don't really want a hack-job HX/VX manifold conversion. Tubular? Prolly would go with a hotrex mani, or take dive and try the OBX-R. -Boost Control? If I'm gonna run on a wastegate spring only (for 8-10psi), do I need a manual boost controler? And lastly...In case I want to build the motor later, I'd like to stick with a T3/4 flanged manifold - but what would be a good smallish turbo with a similar frame to use? GT28RS? GT28? Thanks for answering my noobish questions.
