Hello everyone. I did a search for this and I may be trying to over-think this issue but I also don't want to hurt the motor as it was rebuilt 2k miles ago.
I have recently replaced the twins for a single turbo and I have replaced the stock oil cooler system and lines for -10AN lines and 2x new oil coolers. I know this will affect the amount of oil I need, but I am curious if I just fill the oil like I would normally do (fill, start, shut-off, check, fill as required, repeat), or is there more to it to get oil into all the new items prior to turning the key for the first time since the update.

I have read (somewhere) that I should at the very least, put oil into the turbo prior to the first start up to ensure that the bearings have oil right off the bat... is there truth to this as well?

Any advice from others that have already gone through this would be helpful.

Items used:
BW EFR 7670 IWG twin scroll turbo system
Earl's -10AN UltraPro Lines, fittings, adapters (approximately 15ft of line)
Earl's (501) oil Thermostat w/bypass
Earl's 19 row Wide oil coolers x2

 

yes if you can pour a little oil into the turbo before the first start its good. if not you can unplug the Crank Angle Sensor, or fuel pump relay (which ever is easier) and crank the engine until you see oil pressure.

for an oil change, the first one i would just do like you normally do, and then maybe make a note or something.

 

Definitely prime the oil pump. Not as critical since your engine is not brand new, but you probably have some air in your oil system, so it's best to circulate prior to firing. I would disconnect the fuel pump (relay/fuse/etc) so you don't dump fuel in your engine while cranking.
