Injector help with TD42 with turbo upgrade

[CraigGardiner]

Hi
i have a y61 td42 that has had a turbo fitted.
what injectors should i fit and at what pressure???
i am also rebuilding a y60 td42 and puting a turbo on it,
are the injectors and pressures the same as the y61??

If you intend running a conservative boost with your turbo? as far as I know you don't need to change your injectors but I would recommend getting your fuel pump tweaked by a specialist.

Thanks for that
i will take it down to one next time i go to southafrica.
what is the best boost setting for this motor???

Without an intercooler 14Psi is about the limit, you can go a bit higher with an intercooler depending on what the turbo specs are and how well it's matched to the engine.
As Patch said the injectors if they are in good condition will flow enough to make a heap of power, it's the pump that needs to be upgraded. Anything over 14Psi boost and you will need to have a bigger plunger fitted. It's a good idea to have a boost compensator/aneroid fitted to the pump as well.
