OK MY TRUCK ITS A NON TURBO DIESEL 2900CC 12 VALVE I WANT TO ADD TURBO TO MAKE THE TRUCK HAVE A QUICKER RESPONCE. what would be a safe lbs to run the turbo i dont want to race just want to have a faster responces

i did take the turbo off a saab 2.5 a beleve i got all the komponents i need i just dont know what lbs its the waste gate valve set up on the saab turbo and if its high how do i make it open up so i dont blow up the engine here its a picture of the trucK AND ENGINE BAY
I WILL POST PICS WHEN THE PROJECT ITS DONE RIGHT NOW IM IN THE U.S HEADED BACK HOME AFTER XMAS TO START THIS

you will first need a exhaust temp gauge. when boosting a diesel its more about the exhaust temp then the air fuel ratio. if the exhaust temp goes to high then you know your mixture is too lean. if you have a modern computer controlled diesel engine then all you really need to do is get a custom tune and have your injectors enlarged(cheaper then buying larger injectors).
if you have an older non computer controlled diesel then larger injectors is a must.

as far as boost psi goes you should be fine with any stock turbo wastegate setting. if you find your exhaust temps are getting too high then you can adjust the wastegate to lower the boost. fyi: modern turbo diesel ingines run 20+ psi boost so i doubt your going to get anywhere near that high.

thank u for replyng ok so the turbo i pulled from the saab what are does set up to be. or should i asked the waste gate opens up @? and yes the pyrometer its the one u talking about . what temperature that should be normal ? ummm i dont know if its electronic engine will look Closer or ask the guy i bought it from .

it is a rather small turbo but like i said i just want a quicker response out of the truck will . ok so a stock turbo ussually runs how many psa of boost? also do i need a BOV too

ok confirm its a manual injector pump for the 2.9cc diesel engine

since its a manual injector pump your only option is larger injectors. direct injection injectors are not cheap. call around and see if you can have your injectors enlarged.

diesels dont have throttle bodies so i dont think you need a bov.

most stock turbos run about 12 psi. this is not relevant as your motor uses more cfm that a gas engine so you may have less psi. if the turbo is too small then you may not produce any boost.
