Since it came off a older volvo i assume its prob a pretty small T3. Slap on a walbro 255, SR 370cc injectors and a tuned ecu.
You could get a fmu/walbro 255 and knock timing back at dizzy or use safc2/walbro 255 and knock timing back, But I dont recommend it.
But like blue808 said some larger injectors and something that controls fuel/timing is good. Also buy a wideband, it will save you a lot of headache's if you hve one.
