Thanks for the opinions guys, what are the limits of the TBI power wise and does it last, sure its all in the tuning but my brain just has troubles thinking you can get a tune good enough with 2 injectors. I have thought about a 2jz swap, and a rotory swap but assumed if I'm going through as much trouble to swap into one of those, I'm assuming the Eclipse motor isn't a drop in but its way closer than the other two, then why not go big at that point. Ugh so many choices. My other issue around here is a tuner worth a crap. When I built my TT 4.6 I had to fly in a DFI expert to tune the car and is was far from cheap and i'd like to skip that expense. Are there any well know quest shops for building and tuning in or new Missouri, Springfield to be exact.
