Default What to use as oil feed on a 1.6 NBFL?

I'm building a turbo on a 1.6 NBFL engine. The TD04 I've got is supplied with a oil feed hose. On other Miata engines, there is a bolt that you remove, so you can put in the hose.

On my NBFL engine, the feed appears to be missing. As you can see on the pictures below, there is no bolt or hole.

Can I drill & tap into the engine, or is the oil canal completly missing?



You're looking at the rear of the engine here.

The return on the other side is also missing, but I'm tapping in to the oilpan for that one.

Post 1995 don't have the feed port on the left side. No you cannot drill and tap it.

Most get the oil feed with a Tee off the pressure sensor port near the oil filter. This can be mounted remotely on a flex hose in order to not have it break from vibration.

A few get it from a plate at the oil filter.

Fewer still, but sometimes with TD04's, use a port on the back of the head, left side. It has a recess hex head. I did this method. If you do this, you can go with 6mm hard line and use a 1mm restriction at the turbo. I used a -4AN flex line, with a -4AN adaptor screwed into the turbo that had the restriction built into it.

I like this solution. Do you know the threadsize for this hex port? Are there any downsides?

I'm pretty new to this: if I use a 5mm hardline, would I still need the restrictor?

The feared downside is robbing oil from the camshaft bearings, as there is a restriction between the block and head in the port that feeds the head. Therefore not recommended for Turbos that need lots of oil.

I would use what has been proven, or whatever Sturovo says. I suspect he will say to use the restrictor.

The port in the head is 1/8" BSPT.

Tee from the passenger side. Don't scavenge oil from the head, there's not much to start with and I wouldn't want there to be any less.

link below shows the correct sandwhich plate to use to get your oil. You will need a 1/8 to -4AN fitting to screw into the plate then a 2ft long -4an oil feed line. Use a oil restrictor fitting at your turbo if your running a ball bearing turbo
