Hey guys, need some insight on what I need to do this swap. I'm looking to do a 4.8/5.3/6.0 swap in my car with a turbo set up, looking to run low boost and a carb. I need to know what I need to do to the fuel system in order to run e85 and convert the car to carb. If I need to change fuel pump, add any parts I just need to know. Plumbing and all that I can take care of, so if anyone can give me advise on that let me know.

 

If your TPI fuel pump is in good condition, it will probably handle a low-boost setup. Personally, I'd start with a new, upgrade pump, anyway. You'll need a return-type fuel pressure regulator, of course.

With regard to E85, don't bother trying to convert a carb for it. Just get one that was made for it to start. Most likely there is a boost-reference version available (I haven't messed with a carb for several years, so I haven't researched what's out there currently).
