Need some help

[Yellow 13]

Alright, Ive finally got some freetime to get my supra running again. I plan on using My 7MGTE with the head from a 7MGE. Its still gonna be a 7MGTE just with a performance head I had made for my N/A.

Heres a few things I have some questions or need help with:

-Ive heard of people running N/A cams on a turbo engine. If someone could confirm this for me thatd be great. If anyone knows the ups and downs of doing this thatd help alot too.

-Im looking for a decent exhaust. im on a budget so I was thinknig about getting the HKS turbo downpipe that removes the first cat. I only have N/A exhausts laying around so I was wondering if this would bolt up to the back half of my N/A exhaust. Or would I just be better off welding my own exhaust?

- Removing the EGR. Im not building this car for the street so Im getting off as much smog equipment as I can. I cant seem to find the stopper plates that Ive heard about (to cover the EGR ports). And will i need a piggy back ECU if I take it off?

-Can I use the clutch disc from my R-154 on a W-58?
