Compatibility question
 

I'm in the process of freeing up some power on my 2001 boxster s and I came across the IPD Plenum and the 74mm throttle body. This is a mod I definitely want to do but the price tag is a bit high. I have read that you can use a 2003 C4S throttle body and a 997 v1 plenum. My question: Will this setup work in my boxster? Is it ply and play (are the connectors the same)? Where can I get these parts? Finally, is there an intake that will fit the new throttle body and fit in the boosters engine compartment?
Thanks in advance. Sorry if these questions have been answered before. I did a lot of research and couldn't find anything.
