hey guys, heard plenty of people strapping a turbo to there na and adjusting spark and fuel to suit.... have even heard of some people doing that and driving around un tuned for quite some time without issues! problem i have is a mate has fitted a NA motor into hes bf turbo car! it was previously a bf zf turbo but now its got a na motor in it replacing the old turbo motor so i believe weaker rods, crappier valves and a few other little things are different BUT should the car still idle and run fine without any tune changes?
so it will be a turbo pcm completely stock bf turbo tune but the motor is a na motor!!! at this present time upon startup the car bumps the idle up to about 1100 rpm, then comes back down and throws a engine light! one code is left bank over advanced and the other is right bank over retarted, would this be because of the turbo tune and na motor?
