A single port would be fine but honestly if your gonna go that route I would look into the s280 or a 2860 as you will also run out of turbo fairly quickly. you should be able to make close to 280 on 91 and could on an e30 tune with lower boost and more timing. The injectors are not gonna be worth for most people unless you switch back between 93 and ethanol alot. you dont need a lpfp to run full e85 if you have a 4-port, but it will strain the lpfp a fair bit, its designed to flow petrol and be lubed with petrol.
