Would anyone know if installing a stock turbo (TDO5 12A) to ralliart would require a ecu flash? Cuz i have gather most of turbo parts including custom welded exhaust manifold. I chosing a stock turbo cuz i want avoid changing fuel injectors and any other electronic situations. And referring to question " if so am i better off buying piggyback from rrm?"

 

you will need bigger injectors, and something to control fueling. there's a few options, a reflash and tune is obviously the best way, but a piggyback will work, but it won't make your stock injectors spray more fuel than they are capable of...

just because you got a stock turbo off something, doesn't mean you can just bolt it on an engine that was never designed for a turbo with no further modifications...i'm a noob myself, and i'm still learning... but a friend of mine who is quite experienced with turbochargers and racing/tuning lent me a great book about turbochargers , so i fully understand what's happening before i even begin my build, i've had parts for quite some time now, but when doing a custom build you have to really know what you're doing...someone else may have a more experienced answer

 

I can attest to the use of a piggyback vs reflash and yes I am bias I will not deny that. I have had 4 different piggybacks try to fuel my turbo (before the ripp supercharger) and none worked long term.

What Hackish can do and we are in the middle of an turbo Auto trans project (that ecu is a major pain fyi) but Hackish does have a few tunes that will be close if you acquire the turbo parts that was used for the tune. Contact him for a list if you are interested.
