Also how long to intsall new exhaust? Thanks.

 

Max 6 hrs for turbos and 5 bar. exhaust 2 hrs.

 

Take it to them on a friday afternoon and watch how much quicker they can do it! JK

 

With pieces left over no less!

 

should take no more than 6 hrs total if you have experience from what I saw.

 

I am ready to pull the trigger, I think..

 

The hardest part can be if the sump plugs and / or sump lines fight you. Mine fought as someone had stripped a turbo sump drain and it was TIGHT.
Pull the bumper too. Some don't, but it makes it a heck of a lot easier if you do.
Oh, and change plugs and maybe coils while you have the blowers off as it makes for an easier job.
I did it in a day. Used to be a professional mechanic way back when...
Now I do it for fun.
I did 16G's too. You'll love them. Your clutch won't

 

+1, Do the plugs and coils at the same time.

I'm looking at doing the 24/18g thing and all that I've spoken with have said it's the best time to do the plugs and coils too.

Clutch to shortly follow.
