    Default 2jz-gte - converting to single turbs - anything i should know before starting work?

    Hey all, sick of the twins on the JZS147 2j motor. Anywho, got the new single turbo manifold, external gate, oil line kit and the turbo. Now bare in mind, i do still have the factory computer and iam aware of the boost cut issues the factory computer has. The external gate spring is rated for 9 psi apparently so hopefully that should be ok, i only ever noticed boost cut at around 14 psi with the twins.
    Is there are any sensors, switches or lines that i have to take into account, delete or adapt when going for the new manifold?
    Anything else i should keep in mind?

    removing the stock turbo's sucks, be prepared to cut some rubber lines that are hard as a rock.

    Is the turbo water and oil cooled? if so you need water lines. if not you need blanking plugs to blank off the old water lines.

    you need a bung to block the oil feed line you arent using. You need a filter or something to put on the intake air sensor. you will need some sort of catch can setup as well, or at least a setup to keep the stock system working.

    do you have a new exhaust gasket?
    other than that it is pretty straight forward.

    The new one is not water cooled, just oil cooled. Yeah i assumed most pipes and lines will be fairly persihed. Filter on air intake sensor?
