I aquired a used BAE turbo for my 924N/A Made by Ray Jay industreis looks like straight ahead installation needs a little fabrication for the exhaust There are two fittings on it one on top & one on bottom of the turbo the bottom fitting attaches to a hose that go to the oil pan I am assuming & I hate doing it the upper one is for the oil input. Where would you tie into for oil feed . I know there is no room where the oil sender is . Do you have tee into the oil sender feed or is there a better or easier way to get oil thru the turbo. Is it possible to tie into the cooling system instead for coolling I am all ears . somewhere out there I know someone has been there done that. I have search the internet for any info & batting zero right now. Also where is a good source for parts for BAE turbos?
Thanks

It's not for cooling, it's for lubrication AND cooling. If you connect it to cooling system, you will destroy the turbo on seconds.

You have to tee the oil pressure sender and get the oil supply from there-

any downsides on using a sandwich plate at the oil filter mount?

edit: I believe that's the spot where the 931 gets it's oil for the turbo.

No downsides but 924 NA doesn't have it and it's easier to go to the hydraulic store and have necessary hoses made there.

A better thing to do would be to use a sandwich adapter, the style designed for adding an after market cooler, and use it to plumb in the lines for the turbo. Would be a good idea to add a cooler while you're at it. Something like this:

block -> sandwich adapter outlet -> turbo -> oil cooler -> sandwich adapter inlet

If you do this, you might need to use a shorter filter, but that's really no big deal.

I seriously recommend using a thermostat in the oil cooler system.

The BAE kits originally used a Tee at the sender, and yes the oil drain goes into the front of the sump.

know nothing about 924NA, but would it be worth seeing if a 931 oil distributer might simplify things? Ieola's bound to have the part?

931 oil sandvitch plate can't be used on NA because NA has a starter motor where oil filter should be on 931 oil plate.

And reaching oil pressure sender is about as hard or easy as reaching spark plugs on NA. I did it and definitely have the lines professionally fabricated because oil pressure is NOT the thing you want to mess with.

I did it like that: took off the oil pressure sender, put the 90degree bend and there was a 10cm steel-braided hose connected to it. The tee was on that, at the one end fitted the oil sender, turbo got the oil from the other.

This way the oil sender was around where the ignition distributor used to be, otherwise you have no space and it's easy to ruin the sender thread.

I did a similar thing to raceboy, but used a copper pipe straight of the back of the head and brought it around to the side and braced it to the rocker cover bolts so that it wouldn't flex and crack. I used the distributer so my pipe was a bit longer, and made access to the tee junction/sender/oil feed very easy. The BAE kit I had originally came with a strange mix of brass fittings that allowed it to all stay behind the head, but it made it very hard to get to and it always leaked.

good bad or otherwise - I moved my sending unit as well. I put a brass fitting on the back, attached a hose and mounted the sender on the fender and ran the feed line to the turbo. for the 1-1-1/2 years I had it running like that with no leaks and I do not believe any or much pressure drop. Like Andrew I had some leaks from back there and got tired of never being able to reach it very well. I cannot recall what the oil pressure was at - and at the moment the car will not start (probably because I have been screwing with a new ignition) if I get it started this weekend I will check it for you if you would like.

Thanks to everyone who have chimed in on my oil lines question I really appreciate at . I am going with the oil filter housng/cooler set up on the 924/931 turbo. I have already aquired one Should wiork perfect! A much better set up than trying to adapt tees & pipeing for at the oil sender.since it is rather the tight fit. I am also going to relocate the altenator to the left side of the motor due to the heat generated by the turbo

Please read carefully what other have written.

There's no problem with the alternator, it's the starter motor that gets in the way when you are trying to use 931 oil filter adapter. It's not going to work!

And it's easier to have the new lines fabricated and installed than to install oil sandwitch plate. BTDT.
