For anyone wondering, you can look up a FASPARTS Steel Barb 45 Degree Male Pipe Fitting 5/8" Hose ID x 1/2", use that from your turbo as a barb fitting to nylon hose back to a same time barb fitting size to your block and you should be fine. 1/2 inch NPT to 5/8 45 degree to 1/2 NPT to 5/8 straight. Goodluck.
update on this, i made something very similar and was able to get it on my turbo and engine with it in the car, was a PITA but works as far as i can tell, there is a very very small leak of oil on one of the fittings but as i said its been fine a couple months later...
