T28 turbo swap coolant and oil line questions - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

recently purchased a bb T28 to swap onto my SR20 but the AN lines that are on the turbo have female ends and obviously the block has female ends so what size male to male fitting do i need to adapt them? and do i need to run an oil restrictor since the new turbo is ball bearing?

would this be all i need for the oil feed line?

and the coolant line that goes into the side of the block just needs to be a standard male to male fitting like this? -6 to 14x1.5?

and last and definitely going to be the biggest pain in the cock to deal with is the coolant line that runs behind the head, the factory line just goes into a rubber hose so could i pull the factory banjo fitting hardline off the rubber hose and run an AN adapter with the right size threaded end and a hose barb on the other side?

like this: http://www.summitracing.com/parts/rus-670300/overview/

the lines are -6 so i know what thread size they will take just dont know the thread sizes going into the block

any help would be greatly appreciated

Dunno the thread pitch I would just get full kit an replace all the old parts. Yes to a restrictor. I always eliminate the rear by cutting it at the bend on the passenger fee side and hooking the heater hose directly to it...then replace the upper water neck with the s14 one and use the s14 kit to get better cooling to the turbo and no more headache for that rear line

Is this a restrictor or just an adapter in my line? Doesn't quite look like a small enough hole to be a restrictor and want to double check before I fuck a turbo up

This is a Ball bearing turbo OEM sized restriction fitting,

Ok that must just be an adapter then, thanks

EDIT: this has to be a -4 line but every oil restrictor fitting I see the threads look to be similar sizes on both ends and the adapter I have now is much smaller thread on one side. Should I just go ahead and order one for a -4 line? And does anybody know what the thread sizes on both ends of the adapter I have now are (one side into the turbo, the other into a -4 line) I'll be going to a hardware store tomorrow to figure out what size all if the threads are but it's 2am here so I really can't right now and I have to order this online since nowhere local to me stocks this sort of thing and I want the car to be back together asap

going by the threads the line is a -3 even though it measures as a -4

pro tip: if you ever plan on doing a t28 swap just buy a whole set of lines ready to go rather than figure out the mess of bullshit your used turbo came with

i think i finally have everything ordered and on the way here, so much for swapping turbos in a day
