I'm installing a single and have ran into an issue with the turbo oil drain since it's a RHD and the steering rack inputs are on the turbo side of the car. The only way that I've been able to get it on is by running the braided line under the steering column and attaching it to the oil drain from the stock twins (it's flexible and allows a workable position), which then attaches to the block.

The question I have is if the oil drain has a low point below the oil inlet at the block (caused by having to use the stock oil drains) but the oil drain on the turbo is significantly higher than the block side, would that create an issue with back pressure? I'm thinking that it wouldn't, but wanted to be sure.

 

I mean no disrespect at all, but that is not a good job. Going off the pic, I would point the flex tube in a 45* looking at 2 o'clock.

 

I believe I tried that, but wasent able to get the braided line on. Yeah, right now it's not ideal. I've been scratching my head on it while I finish the rest of the swap.

 

something like this,

 

Also can you swap the lines? Meaning install the flex tube to the turbo side & mount the flange w/line to the engine side. It's hard cause I cant see the lines from end to end.

 

Or flip the flex tube over, having the 90* pointing towards the engine & the flex side pointing towards the turbo. This will help with giving you more angles to bolt the flange to it.

 

I tried pointing the flex line up, but that caused a high point in the braided line that was close to the same elevation as the turbo end, making it so the oil may back up into the turbo. I'm starting to think that the only option is to cut off the flex portions and weld the ends together, so it's just a 1" straight pipe attached to the block and the flex line.

I believe that's what the stock twins were set up for the front oil drain. There was a 1"-2" long straight pipe that connected the block and the flex pipe, which went straight to the turbo. That might be the best option since I can't attach the braided line directly to the block (not enough room to get the rear nut on the bolt).
