Can the trans hold the extra power?
2300lbs and 275-300hp on coilovers would be one hell of a ride I bet (which is really what this car should have been from the factory, or at least an option for it).

1) Going for a built NA motor is going to be an exceptionally effective waste of your money. Cams/heads for the FA20 aren't like the LS world. The biggest and most cost-effective gains come from a catless header, E85, and tune. That will put you around 200-205whp. After that, it's a steep climb for diminishing returns. EDIT: the guy behind Money Shift Racing tried to do the ultimate NA build but gave up before finishing. I think the short block is still for sale. His build thread here:

2) Not easily.
3) Trans is okay for NA power levels. For anything more than, say, 250 lbft, you should have a spare trans on hand. There are options for building the trans or for trans swaps (like MazWorx CD009 swap) but they are expensive. Spares are much cheaper.
4) There's not a whole lot of easy weight to lose on these cars. You can get to 2300 lbs but it's tough. See Anthony's thread here:
http://www.ft86club.com/forums/showthread.php?t=42284. You can get to 275-300whp with a JRSC, which is a rotrex SC unit that has extensive track testing behind it. Sure, it adds complications, but it's among the most reliable FI solutions for this platform.
