so i derped and bought a -3an oil supply line yay for correct size, problem is it doesnt have a 90 degree end for attachment to the block can i still use this or will i have to source another.
Also, the internal wastegate actuator was removed on my turbo and so im not sure where im supposed to put the vacuum line from the actuator, i thought it was supposed to go on a nipple on the turbo, however i can not find anything

 

On my last car, i didn't have a nipple on the turbo for a vaccum line, so i just welded a nipple as close as i could to the compressor on my intercooler piping. It worked great like that. However, i was using an external wastegate, not 100% sure it's the same, but i don't see why it'd be any different.

 

well good news is i was reading up on a build thread and a guy mentioned Joe Perez's boost sag thread, so turns out it doesnt matter that i dont have the stock nipple
