My Rb25det Wierd Problem

[FalahR33]

Hey experts, my engine will at the begining pulse like a purrrrrrr and then between 2000-4500 will only my turbo kick up.then after 4500 my engine is kinda retired from its turbo aspiration completely. no air leaks that i know of, turbo spins properly like they say in the nissan service manual. is my bov screwd up? my plugs failed? my aac valve? my coilvers/

and why in traffic jams does the engine heat upto 90-95%? mechs say the engline is allright.

ps. this is ksa so heat is kinda 45 degrees here in summer.and traffic jams, turbo engine all that rounds up too much isnt it? so should i get myself a vented hood or extra fans or what?

thanks for reading the post atleast.
