What's needed for turboing a 4.0
 

Hello everyone I'm new on here and I'm makeing a project with my 96 xj 5 speed. Motor is completely stock and I'm looking into turboing it. I did a complete motor refresh 42k miles ago . My questions??? Lol
what size turbo? T3 t4
injectors
maping
o2 sensors
what mods have to be done
blow off valve?
what intercooler will fit and where
(it is lifted and does go in the woods plus driven on road)
Basicly everything please help

The first thing is to decide what amount of boost you want and at what RPM. Unless you want the boost to peak at 1500 RPM and the turbo to run out of breath by 3500, a T3/T4 hybrid is probably the wrong choice - they're meant to provide very high boost on small displacement engines that don't have a large exhaust volume. You'll need to set goals first, then size the parts accordingly.
