A pro can have the old ones out in 5 hours and the new ones in before the end of the day if they work straight. Might run you $700-900 but thats the cost of having a 500HP monster

If your serious about doing this here is a quick list of tools off the top of my head...

T50 torx---Manifold Nuts
11mm deep socket---Manifold nuts
E8 external torx---Heat shields
T30 torx---Oil and Coolant lines
8mm---splash shields
E10 torx---Steering shaft
16mm---aluminum thrust plate
E14---motor mount
E12---water pump
13mm---v-clamps on cat
12mm---exhast collector

This is just off the top off my head. Dont forget the wastegates need to be adjusted, so you will need a vacuum pump. Again, I want to stress that this is not a light job. And not a job I would not want to do without a lift. The front turbo can actually come out the top, but the rear turbo has to come out the bottom.
Wait the subframe rail must be removed i thought it was the seering rack that needed to be dropped and then you have access, I'm 100% sure That i WILL be doing it. haha i work at a regular indy shop and that where i do my walnut shell blasting every weekend. I do have a ton of tools and the waste ages do come adjusted from Vargas. I'm pretty mechanical and if i had to pull the N54 guess what its coming out
but not gonna pay to get it done just cuz i work at a shop don't see the point.

Are you saying this off the top of you head from experience? haha
