Vacums Wiring and oil lines for Na-t? help!
Alright everyone, I am having some problems i have a 1994 Sc300 (not mine) and i am installing a na-t and i just wanted to confirm somethings before i strarted things. Well Basically just wondering if anyone has a diagram for the vac hose's that go from the Wastegate to the turbo and BOV how is it supposed to be set up?
the second thing is the feed line for the turbo i am not quite familiar with these engines. i am more familar with the 2jz-gte and supposivly the feedline is supposed to be picked up from the oil filter? does any one have any pix of this?
thanks
Jason

The BOV needs to see vacuum at closed throttle so it must be a manifold source.
I don't know how the oil pick up line works for the NA-T as I havn't studied it to much. When I did my last NA-T car (not a Lexus) we ran the line off a Tee we installed off the oil sending unit. Basically b/c it was closest to the turbo. Look around and I'm sure you can find some pics on NA-T cars.
Good luck

The union bolt is the big (22mm?) bolt next to the oil filter.
It holds the whole assembly in place.
Take it out, drill it, and tap it for an NPT fitting.

on the wastegate, side port connects to a boost source from the turbo compressor housing.
the top port connects to the boost controller.(output)
