Oil restrictor necessary?

[daveyfx]

Hi all,

I have a 2G GST currently receiving an EVO3 16G. The install kit I received from turbochargers.com included what appears to be an aluminum restrictor that actually threads to the feed on the turbo and then the SS feed line threads on to the other end of the restrictor.

Prior to the 16G, I had a 14b and was running an SS line from SBR which did not use a restrictor, rather used a banjo bolt in the feed.

Is this restrictor necessary or should I continue to use the banjo feed? The CHRA looks like it has a restrictor in there anyway...

Thanks!

Only ball bearing turbos need restrictors. Thrust bearing turbos need regular oil pressure since the oil actually "acts" as a bearing. Don't use the restrictor on this application.

Thank you. Any idea why turbochargers.com would include one in their kit then? Is it marginally cheaper than including a banjo bolt and fitting on the feed?

Here's a pic of the kit. The piece I'm talking about is right above the j-pipe.

The blue fitting above the j-pipe is not a restrictor fitting (a restrictor fitting has a very very small pin hole on one end). It's just a male 4an fitting to screw into the top of the turbo just like the banjo bolt would. The you will screw the smaller brass 90* fitting to that then connect your 4an stainless steel oil feed line. And then the larger brass 90* fitting with (I think) the size is the 4an x 1/4" NPT--screws into the oil filter housing. Connect all the lines up and you'll be in business.

Either way you can run a banjo bolt style or use the fittings Turbochargers.com sends you. I used a banjo bolt style on my old evoIII 16g.

That's not a restrictor, that's just a metric to AN fitting...

Ah... thanks for clearing that up. Good, as long as it's OK for me to use the banjo feed I think I would rather take that route for simplicity's sake.

I always hated the banjo bolt style for feed on my 16g. It all came down to being a pain to deal with crush washers not always staying in place. I don't have the patience for that stuff. I think the Turbochargers.com feed line kit is a little more superior because it is all screw together and you don't have to deal with crush washers.

In order to quell future confusion, thread euthanised.

A banjo fitting is not a restrictor.
