Hi guys, I'm looking a patrol y61 with zd30 (not common rail) but the car have a problem. The owner put new turbo, injectors, maf and pressure sensor and check fuel pump. The car dont have power but dont smoke

What do you think guys that could be the most commun failures that can produce that? I'm thinkings about intercooler or valve that controller the turbo... but I think that normally when you dont have boost the car should smoke (too much fuel and not air)


Thank you guys
