This is the oil feed 'T' piece that came with my kit. There is no restriction as far as I remember.

But this is the piece that doesn't work, right? It has the wrong size fittings, I think, and needs to be worked around. Have you tried installing it?Are there perhaps restrictors in the connectors between the feed lines and the turbo housings?

i went to a local commercial fluid transfer specialist and brought fittings that did the job for around 20 gbp. they had to order one part, took a couple of days. if you are UK, then pertec was the company.

i haven't put any restriction in there, and the tt installation book didn't mention one, may be that the internal dia of the supply hose acts to regulate the oil flow, none has reported failures yet...

the oil pan fittings supplied are gash... i hate them, i had the dam things welded into my oil pan... they leak like a f_ck.

if i were doing it again, i would use some screw connectors and flexi hose straight from the outlets to the sump, maybe bend a profile from the crap supplied to route the flexi, using tie wraps or whatever.

Went through the notes of my install.
Below is the TT drawing for the oil return.

On the supply there is a thread size mismatch.
TT supplied M103 kit adapter has a M14x1.5 thread to install the removed oil pressure sender unit.
Problem is that the oil sender thread size in the oil filter housing is M12x1.5 female.
You need to adapt the TT to the filter housing size.
We took the M14 from the TT fitting as shown in E320coupe pic above and brazed on a M12-1.5 coupling.

I wonder if the M104 kit was supplied with the correct thread size ????
You can't have too long of a coupling as there isn't much clearance between the fitting and the bulkhead after it's installed.

No restrictors in the supply.
No reason why you can't use a flange type fitting on the pan...
Doubtful any calculations made on the return as the size of the return hose will determine max flow.

I had to make an adaptor to make i fit.

In retrospect, does anyone think it would have been better to tap the sump in a different location? I don't think there are too many choices, but the passenger side of the oil pan comes to mind.

The TT drawing locates the two return lines on the passenger or exhaust side of the engine.

Thanks, Ed. When I first looked at your drawing, I presumed the notation "Front of Engine" referred to the view, not to the designation of one end of the sump. Thanks for clarifying that.

TT can be confusing in their documentation.
The dimensions are taken from the centerline of sump bolt # 4.

The fittings they supply are British Standard thread so they don't match anything else in the kit or on the car.

I would seriously consider the modern flange type that are fairly easy to source.

the leak problem is not, in my case, dur to the nut supplied with the kit, i welded them into the pan, in the advised position. the leak comes from the silicone hose that pushes on, then uses a jubilee clip to hold it. i would get an elbow with threaded connectors on one end, and weld that into the sump, and use a hose with matching threads. then it would be oil tight.

What are your guy's opinions on tapping the block low on the skirt for a turbo oil return and putting an A/N fitting on it?

Too much work required to tap the block and no reason to when the pan/sump gives much better access..

there is a restriction part C also reduces the amount of oil that goes to the turbo, the hole on the side with the fine thread is much smaller. i will see if can take the one on my car off tomorrow and take a picture.

to fit mine in I drilled another hole on the oil housing and tapped it

This is TurboTechnics ???

yes its a turbo technics kit
