And wow, this is a massive build. I would focus on getting the swap done first though. If you try to do all the above at once...I think you will overwhelm yourself.
This is true, but I'd suggest boring it out and port-matching it to the TB. This is what I will be doing with my Helix TB spacer. It is made for the stock 54mm TB, I am going to bore it out to match the Inline4 68mm TB and already port-matched 68mm upper plenum.
@Chris, Yeah, the suspension parts, especially the F2's, are less of a priority, but the brakes and U/R parts are some of the first things to get done. That was a typo with the RSB, thanks for pointing that out.
@Nikita, I am sure there are shops here that could probably do that for me, I really don't want to many places involved with the build, so I would probably just get the P2R one and be done with it.
