walbro it depends on what turbo you have/plan on getting i believe the 190 is good for you.
for upper intercooler pipe try dejon tool..i'ts either dejontools.com or dejontool.com. Mine is a roadrace engineering one and it was pretty cheap. Wellman boost controller? never heard of it.I have the hallman ES manual boost controller. Turbo XS, Hallman, Joe P..they are all good manual boost controllers.. if you want a electronic one get the apexi avcr or greddy profec-b..they are quite expensive though. For gauges. Boost, Air-Fuel, EGT. Those are 3 gauges that are just about REQUIRED for modding a 4g63. You can find them anywhere for about $50..shit even pepboy sells nice autometer ones now..but the EGT gauges are expensive..like $160ish. For blow off valve if you want a cheap good one get the 1G.. you can get them for like $60..they hold a lot of boost and are good. If you want a nice sounding one that holds a lot of boost get either a Greddy Type-S (Type-R if you are running a huge turbo) or HKS Super Sequential.. those seem to be the 2 most common blow off valves for 4g63s. You can find them for about $150ish-$200.. not sure.. i buy most of my shit used. Just becareful from who you buy from. Hope this all helps. later

You don't need an A/F gauge. It's a waste of money cause A/F ratio isn't reliable to tune with at all. Boost, EGT, and water temp or FP or Oil pressure or oil temp are better bets.
Also getting a Walbro 255 is probably a better bet if you want to upgrade big in the long run and you can get them for 105 shipped from autoperformanceengineering.com.
Also going with a 1g BOV isn't a bad idea cause the hold about 20 PSI before leaking.
Oh and I recommend the Hallman MBC. They are rock solid.

the 1gen will hold 20psi when it is crushed properly..... a reg stock 1gen won't hold up to psi by itself

If you want to pay a ton of money, Greddy is fine. However, RRE and Dejon Tool make great quality stuff for a lot less. Also, the 1g BOV will work perfectly well for less than half the cost of a Greddy one.

I'm going to have to disagree on this one....... with a crushed 1gen you can run up to 20psi...... it will leak at around 15-16 psi if you don't crush it......... I'm going by experience on this one and also conformation from jeff hill on it.....

I have been running 20psi daily for a year with my stock, uncrushed 1g BOV. I hit full boost at around 3800rpm on a Green. I doubt it is leaking much. It may leak a very small amount, but hardly enough to consider it a problem. Plus, when you crush a BOV it actually has the negative effect of not working properly at low boost levels. That means at partial throttle where you may only build 10psi, the BOV will not work properly.

At this point it's an argument over semantics. Jeff, from personal experience, has run 20 PSI daily with no noticable leaks but Icedout has heard from Jeff Hill that 16 PSI is about the limit. In this case it's safe to assume that once you get close to 20 it will start leaking noticeably (perhaps). Basically, you'll need some serious mods to run close to 18-20 PSI safely so for this purpose putting a 1g BOV in the 2g is the way to go.
At what point a stock 1g BOV leaks isn't an exact science so let's agree to make 18 the magic number with a +/- of 2 PSI. That way everyone is happy.
