Default DD MS6 GT30

Hey all,
So I'll be installing a GT3071r in a few weeks and have been doing a lot of reading but still have a few lingering question for the speed6 BT guys.

I'll be cleaning my intake valves this weekend, car has 65k on it and to my knowledge haven't been done yet (no OCC or EGR block off)

(mods in signature) I'll be using the stock exhaust manifold and fabricating a way to support the turbo with the stock turbo support. So the turbo will be in the OEM location.

1: Are there any real concerns with using the stock oil drain line if the line isn't bent or anything? I've read about lots of people modifying the stock oil drain line to fit a 10-AN fitting onto it. I've read of one guy using the stock oil drain line, but he only commented on a thread. bt oil drain line for MS6
2: I know I'll need the step down studs from ATP if I use the stock oil drain line, are these really as bad as people say?
3: Can the stock oil feed line be reused?

I'd be replacing all crush washers/gaskets, etc
I want to reuse the lines because I'd rather not have to weld.

The coolant lines aren't that big of a concern, I'll be buying banjo bolts and running new coolant lines.

My power goals are 350whp and not going over 18psi, which is unlikely but either way I won't go over 18 psi. My compression (cold engine) is 185-180-182-185. I'll be replacing the CP-e TIP that necks down to 2" with a HTP 3" TIP. I'll also be porting the wastegate on the turbo to prevent/lessen the turbo creep. And switching to a 3-port electric boost controller. I'll be updating this as I progress. Any words of advice would be awesome.

Thanks,
-Rob

the stock oil return is too long to fit a gt28/gt30 turbo.

Well that's a disappointment, but thanks for the input. Looks like I'll be fabricating one up
