some ?'s after the HSR swap
hey guys i just swaped to the HSR this past weekend. i had problems trying to get all the sensors to fit into the new manifold, so i had to go to the hardware store alot to make everything fit right. did u guys have the same problems?? and what did u guys do with that vacuum line that goes to the EGR, did u jus plug it or what do i do with it?? and how did u mount the ignition coil since there isnt a spot on the manifold for it no more? and last question did u have to plug any of those holes on the upper manifold in the back or did they all get used?? cuz i have 3 out of 4 used right now..
Re: some ?'s after the HSR swap
Plug the EGR vacuum port on the throttle body. Mounting the coil is a preference choice but I mounted mine on the firewall lip after drilling 2 new holes. Vacuum ports I used are..... topmost for the MAP sensor, next for the vacuum line for the heat and vacuum canister, next for the brake booster, and finally the bottom most for the IAT sensor and of course the one underneath in the middle for the PCV valve.

Re: some ?'s after the HSR swap
I have 2 out of 4 holes plugged in the back. Dunno if i'm missing something? But everything seems fine...
I have an extra coil mount for sale in my thread if you need it, just bolt it down and go.

all of my sensors pretty much found a drilled and tapped hole...dunno if they are the correct hole but they all found a home lol
