Minimum needs: 60s, boost a pump, maf, tr6 plugs, tune.
Other things I'd look into are: idler pulleys and a larger heat exchanger.
The list can go on and on.
Look around on here, this set up is well documented
I agree with the above about 700 on corn. But he'll need more things to support that 700, clutch and trans upgrades, more fuel ect...
What's minimally needed vs room to grow are two different ideas here
I guess no one asked what boost level you plan to run. I believe a 2.3 Whipple makes 15 psi with a stock crank pulley and the supplied 3.5" upper which is perfectly fine for 91 octane. As stated above all you should neeed is 60lb injectors, larger MAF, colder plugs and a tune. Also consider swapping the cold air intake if you're still stock.
