Turbo oil feed and cooling lines

[waldo320]

Hey all I am doing a 94 NA conversion and was wondering what the best place to put my oil feed line, the return no prob there just tap the oil pan, next how about cooling feed and return. Thanks for the help!!!

For the oil feed line, look at how people install oil pressure gauge senders; there is a plug on the rear top of the engine block that mirrors the one for the stock pressure switch. The stock switch uses an adapter that has female pipe threads on it, so if you get another such adapter you can put it in place of the plug on the rear.

For coolant, maybe you could just plumb it in series with the IAC valve and throttle body. Or in parallel with the heater core.

I wouldn't suggest using the IAC valve line. You need something with some more flow. The heater core lines should be adequate.

Just to let everyone know what I did for my cooling I used plastic T's to the heater core, and for the oil custom braided -4an with 10mill fittings to the 12 mil allan key bolt at the bottom of oil pump and for the oil return I got a oil cooler feed that goes in between my oil filter and the block from summit for 25$ caped the out put and put a 1/2" hose adapter on the other side to my oil return. Sure beats trying to get that stupid oil pan off!

Did you tap off of the discharge side of the oil pump?

The only issue I can see is the fact that the differential pressure between the pump and the oil return on the filter may not be that great, which will reduce the amount of oil flow to the turbo.

Pretty postive I got the feed the one on the right, and well see if i have any problems I will just run the oil feed from my new adapter and the pressure would be equal there.
