Q: If you owned a Sunbird SE 1991 3.1L 6V, what would you have under the hood, I'm trying to supe up mine, Idk where to start, don't get too fancy, afforadable..Thx, best creativity and possibility to do so, gets 10
A: See www.jbody.org or google for similar letters. The 3.1 is not a powerful soupable engine. 3.4 is. It definitely needs a header, tuned exhaust and a computer re-program from the Jet Programmer or a Venom unit, not likely available to adjust parameters for an older vehicle, not our fault, but where's the market? Auto Anything has a bunch of interesting parts.
