Question for the turbo 4 tec gurus

[SLASHER]

About fit my custom Precision turbo to my rxtx .

What is is the max hole dia that I can run to the oil feed to the turbo without effecting the oil pressure of the 4 tec ...

The return line is 15mm

but I was told if I don't close the oil sprayer off to the SC run around 1.5-1.6mm and if close I can run 3mm to turbo feed ..

Any help will be great ...

use the small restrictor ( the one that usually comes with the turbo ) so you wont have oil drain problems

[SLASHER]

It's a used kit , just need to know what's max size I can go before the oil pressure of the 4 tec faults.

Or is it run it first with small and oil gauge set up then keep increasing till safe fir both .

Just need ever a base line

[skidoochris]

too much oil is hard on the turbo seals

[SLASHER]

I will run first small then increase if needed and keep the oil pressure in view..

If its ball bearing then it needs next to no oil
The Garretts have the restricter generally built into the core

It's a Precision J Bearing
