(ok old news for most im sure but i thought i would share)
For the 14b swap supposedly you use the 1g dsm water and oil lines I thought. I just used all the original 4g61 lines and it worked out great. The only issue is the banjo fitting side of the 4g61’s water line (the u shaped one that goes under the turbo and hooks to the water pipe) has a 12mm hole but the 14b needs a 14mm hole. That must be why its recommended to use 1g dsm lines. I even had purchased a supposed dsm line but the line was a much larger U shape and I found it too difficult to bend into place so I just used a 9/16 end mill and drilled the hole larger in the original 4g61 u shaped line. (a milling cutter is uber clean but a drill bit would work too)
Now I know some may want to say… wait its metric and don’t drill out a banjo fitting it wont seal etc. But a 9/16 drill bit equates to 14.2 mm which is no problem at all just a lot more common. As for drilling the banjo larger I wish I had taken a picture to show that the banjo boss for the 4g61 line is exactly the same size overall as the dsm line( ie plenty of meat left). The 4g61 just had a 12mm hole bored through it instead of a 14mm on the dsm. Im on the super cheap with this project partly just for the challenge of it, so I inspected and reused all the copper washers and haven’t had a problem so far.
Long story short this is super old news and way late for most guys but to swap a 14b onto an original csm turbo car you can reuse all original lines and washers (as long as they haven’t been used a bunch of times already) all you have to do is enlarge the banjo eyelet on the U shaped water line coming from the water pipe to 14mm.
And remember every machine and welding shop in town will have the 9/16 bit (14.2mm) and would probably drill it for you for 5 bucks.
Here is a pic of the u shaped line I did not use just for a reference as to what im talking about.
