that, sir. is basic automotive knowledge.
do NOT do any work to your car for a while.
spend some time in front of the computer, talking to mechanics with the basic intention of gaining some basic background of knowledge.
the brake booster is the big round thing that the brake master cylinder bolts to.
and to your other thread, if you have to ask, it's too hard.
the intake manifold comes off quite easily. but i suggest you spend a little time reading, and gathering knowledge before doing such a thing. read into the vacuum situation, and since you're going to remove the charcoal canister, that's almost all of the vacuum lines on that side of the engine.
now, in the meantime studying on how to remove the charcoal canister and egr, you can look at the link i posted earlier, and figure out how much hose to order. once you order your hose, buy some egr block off plates (
www.suprasport.com ,
www.jblmk3.com are two sites that sell the plates ), and finally purchase an intake manifold gasket set. then figure out how to successfully route the vacuum hoses.
once the knowledge and supplies are there to tackle the job, enjoy.
this engine bay can only be improved upon, so good luck.
just be smart about it. dont dive into anything before gaining previous knowledge about said project.
