Exclamation Single turbo install: Did you remember your restrictor pill?

Bah! I didn't.

What kind of oil feed line restrictor pill did all of you use?

Well, considering that the engine pumps somewhere in the vicinity of 110 psi, and the turbo only wants 60ish(?) psi, thats not good.

I think I found out why I was being James Bond.

you dont actually put a "restictor" in your oil line...the restrictor is part of the oil feed adaptor that fits in to the top of the bearing housing...pull that adaptor off and look to see if it has a "pin" hole size opening in it..hence your "restrictor"

Steve:

The oil feed adapter, is a standard A/N fitting. It shouldn't have a restrictor, should it?

I used 2 AN fittings, and 1 NOS hose.

How big is the 'pin hole'?

Size of a 60' holly jet? or so?

Or size of putting a pencil tip in 3/4 the way?

Yep... Mine is the size: AN fitting 3. Almost large enough to fit the entire holly jet inside it.

Grr... Where do I get this fitting?

mike,
pull that AN fitting to see if there a "pin hole" opening.. these types of AN fitting are commonly known as "oilers"

Thumbs up

Red-Rx7 had a .62 Holley jet on the bench and we drilled the AN fitting and forced that bastard in there. No more smoke and no need to check the oil when filling up with gas now

Most turbo shops are closed at 12AM We needed power right away.

Have a nice day.

You can make a "restrictor" by buying a Holley jet#60 or #62. Use a 1/4" NF tap (and 1/8" drill bit?, it should say when you buy the tap or you can reference a chart).
Drill the AN fitting (I used a -4AN to 3/8" NPT) on the CHRA side or NPT side.
Tap it with 1/4" NF tap.
Lock-tite the Holley Jet in place.
