Default WRX-ish powered '99 RS-t

I will soon be acquiring a '99RS with the following modifications:

80,000 miles
ACT Clutch
Exedy Flywheel
STi short shifter
Stock powered otherwise, never boosted.

I have the following WRX parts laying around for use, are these all compatable for a budget turbo kit conversion?

APEXi AVC-R boost controller

fuel pump
Intercooler+plastic piping

I have access to purchase a used Downpipe.

What am I leaving out to complete this project?

I am going the same route right now... And I am about to drop a Grand on the stuff that is required to do this setup safely. And that price in no way includes all the WRX hardware I already have.

Do alot of research and really weigh your options.

You can get by with a S-AFC to control your fuel to an extent...

Are you planning on using a WRX up-pipe as well or going the custom Up-pipe route?

If you are using a WRX up-pipe, you will need a WRX or a Legacy Turbo Crossmember, wrx exhaust manifolds to mate that up...

You will also need coolant lines (feed/return), Oil lines (feed/return), WRX oil pan for the xtra baffle and weld in a return bung.

Some gauges would help too: EGT, Boost, Oil Pressure....

Don't plan on using the boost controller until you get some timing control, and the BOV really needs to be recirculated on the 99's... an S-AFC will not be able to accomodate for the additional fuel in the CC when the valve vents. You are on the right track though, oh and you will need some custom intake work done to mate the breather hoses/PCV and BOV return plus your MAF to the turbo (the WRX OE intake will not work due to different intake manifold designs).
