Can someone tell me how and where the oil feed is connected to the block for the turbo, how the pressure is regulated and possibly the thread sizes?

-Thanks Andy

it feeds from the filter housing.there are already bolts in the housing.
dont know the size im afraid,AFAIK there is no pressure regulation it just flows through and drains to the sump

Cheers, anyone out there know the thread? prob something like M20

Andy

18mm sparkplug thread. same as oxygen(lambda) sensors. don't know the thread pitch. etc.

M18 1.5, and its the bottom one that is used to feed turbo, i use the top one for an oil pressure gauge.

Aaron.

why are there two feed there anyway?... seems kinda random almost like fiat wanted you to turbo the thing

wonder if oil coolers were fitted/planned in hotter countries or for other unbuilt models using the same block

cheers guys

If you look carefully you'll see that the top one is after the filter and the bottom one is before the filter, so if you use the top, you would get a filtered oil supply and if you use the bottom it is unfiltered oil.

so what one is best to use for a turbo then? top one?

I'd say filtered for the turbo & unfiltered for the cooler as I'm guessing a turbo getting random pieces of metal in its bearings gonna be more of a problem than the oil cooler

Mmmm dirty oil through a Turbo's bearings cant be a good thing surely, Do the Novitech ones use the bottom or top feed?

Wouldn't it be an idea to put the return straight through the oil cooler then to the sump rather than do a direct return?

(just some of my pondering on the pipe dream of turboing the cinq )

so if i put:

the lug screw thingy for oil for turbo in the top screwhole
then feed that into an oil cooler
then out the cooler into the turbo
then out the turbo back into the sump?

or how should i do it?

I was thinking

Sump - filter - Turbo - oil cooler - sump

but no doubt one of the Turbo guys will come up with the correct answer I can't believe that this wouldn't be the norm if there wasn't another reasoned argument.

if im at the turbo tomorrow i'll double check but i would go turbo then cooler to cool the oil post turbo.
then into the sump
if no cooler then direct from the turbo to the sump

if you could check that be great cheers

well turbo>cooler>sump it is then lol cheers guys

if you brighten this up you may be able to see

hmmm not to clear.........


ALEX!!!!!!!!!!!!!! get ur ass in here lol

You can't put turbo and oil cooler in series, turbo will strict the flow.

Each one needs it's own line. Turbo feed can be taken from the top bolt of the filter housing or with a T connector from the oil pressure warning sensor and drained DIRECTLY to the sump. Draining should be as quick as possible, it needs to flow without restriction, in order for fresh oil to enter and cool the bearing. Max pressure will be 4-4.5 bars, regulated from the pressure release valve found at the oil pump. Internal diameter of the hose can be 4-5mm, enough for the needed flow.
