Excuse my lack of knowledge here......

Do all turbo kits / fitting require an oil line to be plumbed
into the sump ?

For that matter what are the oil line requirements in general ??

Even the basic Greddy bolt on kits ???

Thanks for your help.

Regards

From what I herd HKS kit uses the dipstick tube for the oil return.
But the others require a hole drilled in the side of the sump, generaly around where the airconcompressor sits, with a barbed fitting so the hose doesnt come off easily.

Im doing a custom highmount manifold, so ill be getting Maltech to come round (As his in my local area) and make up my Oil and water lines to the turbo with braided hose for extra bling
But Ive gone to Pirtek for the return in to the sump and got my own hose to with stand oils and higher heat and brass barbed fitting 5/8 i think from memory and a braied selve to protect it futher.

I hope to soon post up a new thread with some pictures to show you what im up too.

So.... I'm assuming that all this requires sump removal to drill the hole for the return ?

Is the HKS dip stick \"fitting\" available for other kits and turbo fitments?

Thanks for your help.

regards.

HKS uses a slightly larger diameter dipstick tube with a 20mm??? nipple brazed to the side of it to attach the turbo oil return pipe. Quite a clever idea I thought and it seems to work fine.

So......where does the oil feed line originate from ?

thanks

regards

No, it can be done with the sump attached. I followed the Flyin' Miata instructions, which included covering the drill bit with heavy grease to catch as much of the metal pieces as possible and then to attach the oil return line to the sump and pour mineral spirits down the hose to flush out the sump (sump plug is removed for this). The hole for my oil return is almost at the front of the sump, and 5cm from the top so that it does not clash with the air cond compressor.

On my T25 turbo there is a metal pipe that the oil return hose attaches to, as well as a water pipe as it is also water cooled.

possible try and go a unf thread as the wall thickness of the sump is pretty thin.

I must admit the dip stick oil return idea (HKS) is a very neat piece of engineering.

I wonder if you can purchase just the dip stick from HKS ?


Thanks

go to auto barn and they have xx diameter high temp hose that doesn't cost much. I'm not sure with the avo manifolds as the turbo return line might run closer to the manifold or turbo.
i have a greddy manifold

Think about It it is your engines life blood that you are feeding to that turbo so for a few extra bucks it make a lot of sense to use braided line (FWI its not that much )

I have 2 NA6 sumps with oil return line fittings already installed.

Email me for pictures and details if you are interested.

The AVO kit uses a high temp rubber type hose - you can get similar from pirtek and it's definately upto teh job.

But to be honest the braided hoses are only about $50 a throw.
