After some help from bodieanddoyle regarding fueling the planned pinto turbo on boost. I am a little stuck with how to get oil to the turbo. I initally thought about using a sandwich plate designed for an oil cooler, but this would mean having a long feed pipe (which I have been told is okay) and a long return pipe (which I have been told is bad). I spoke to a Lecture at College who suggested using a oil pressure T-piece and instead of using it for an oil pressure gauge, use it as an oil feed to the turbo. Is this a good idea, or would I loose oil pressure to the head? Found this on ebay, seems like it would be up to the job.......  cgi.ebay.co.uk/SIERRA-ESCORT-COSWORTH-TURBO-OIL-PRESSURE-GAUGE-ADAPTOR_W0QQitemZ180226278808.....for the drain/return, there is a conveniant threaded hole at the bottom on the block on the exhaust side, which will sit nice and close to the turbo. This appears to lead straight to the sump. And from the pics I have seen of the TT conversion was used by them as a return to the sump. |

I know that when they were building a homebrew X-flow turbo in RF they used a return straight to the sump.
The thing i always wondered about was ensuring that you had enough oil pressure at the head if you were diverting some of it away for the turbo - high pressure oil pump solve this?

turbo doesn't use huge ammounts of oil, sometimes its nesecary to fit a flow restrictor. straight as possible return route is needed, and enter above the level of oil in the sump. |

the SS1 1800T uses a nissan silvia 1.8T, the oil feed from that comes from a T peice on the oil pressure sender and thats as nissan built it! so again, the answer would be a yup!

What you doing for your turbo oil drain then? Quite important to get that right or you'll start losing oil into the inlet or exhaust tracts past the turbo seals.

From an old copy of Classic Ford, the editors Corsair is being fitted with a TT pinto. There is a pic of the engine out of the car from the exhaust side, the drain pipe from the turbo leads to the back of the engine block. On my 205 block there is a blanking bolt there. I plan to run the drain pipe to this hole. Said blanking bolt.........  |

our skylines use a larger diametre return pipe back into the sump, just a simple pipe but obviously above the oil level line, worth double checking if the return diametre is critical

Yeah loking at the size of that hole i'd say you might be better off with a pipe welded into the sump.

The return from a turbo is only really helped by gravity so it must be lower than the level of the turbo and as least restrictive you casn get it.....which means the bigger dia the better.
I used a t piece off the pressure sender on my turboed fto with little or no pressure loss at all.
