If your planning for higher then 5 psi i'd have to say I would NOT go for a rrfpr or anything of the sort. I'd highly recommend, in my lowly opinion, that you up the injectors to atleast 450cc (theres a calculator for this someplace)and go with an electronic piggy back system (SAFC, EMANAGE!)seeing as anything higher then 5psi the mechanical systems will max out. You'll probably need to add in a fuel rail to your list.
I would also recommed just getting a Z32 MAF rather then a hacked stock maf just for the sake of reliability and tidyness.

If you need to skimp, skimp on the intercooler, the turbine itself, the piping, the manifold, etc. Do not skimp on the fuel system!

ps.
I know a good fabricator i'd like to plug too, so if you wanna know who PM me.

pps.
Plan to be boosted next week kids!
Heres my list to compare to.

Turbo Stuffies
Custom angled manifold (clears stb and brake mc with heat shield) 300-something$
!Mystery Hybrid Turbo from a 6.5L Diesel by Borgwarner-IHI - 350$ (I'd say for 5psi-7psi Get a T3)
I/C Off a blown civic (Get a Cheap Side Mount)
!Tial 35mm Wastegate with 6lb Spring
Z32 MAF
!GReddy Oil Press Gauge (Oil means life for your turbo, I think Autometer works fine but I got a deal on GReddy's, don't buy the autometer a/f)
!GReddy Exhaust Temp (Good when paired with dyno #s)

Fuel System
255 Walboro Pump
450cc DSM Injectors - cheap and easy to find, and injectors dont really wear out
Custom Fuel Rail (A Must with DSM injectors, because they dont fit)
GReddy Emanage (<300$)
!GReddy Profec-e01 (pricey but tunes timing and fuel with the emanage, but the profec-b is MUCH cheaper)
!Knock Off HKS BOV (I don't know how it works so I won't recommend it, 1st gen DSM BOV should be fine)

This is all to run 10 psi safely in a daily driver.
(!=use something else and save $$$)
