Oops! It's
http://www.iboost.org not .com. My bad. Their site is under construction, whatever the funk that means, but you can still e-mail them from there.
I've heard good things about the starion I/C. Good luck finding one in a junkyard. They have them on E-Bay all the time but they usually don't go for cheap.
EGT gauges don't usually go for 50 bucks. Maybe 100 if you're lucky and then you have to buy the sensor, another 100 or more.
The Bypass valve in question is a HKS standard. Should be good for my low boost setup(7-8 psi). It's always upgradeable later. Yes, you would recirculate the air back in before the turbo but after the MAFS.
You'll never see 10 psi with a rising rate fuel pressure regulator. Raising fuel pressure to flow more fuel through your stock injectors is an exponential function. Meaning, to double the flow, you'd need four times as much pressure as normal. Hope you have a fire extinguisher in your car.
An EIC or AIC allows you to add more fuel injectors, 1 or 2 just prior to the TB or one in each intake runner, that will inject extra fuel under boost. Short of larger injectors with ECU tuning, this is the best option. SDS makes the cheapest one I've seen so far. Greddy make a system called E-Manage. If you buy the extra harnesses and the software you can use it to control some extra injectors. Looks pretty sweet but it's not within my budget. Some other companies like HKS and Blitz also make these controllers. Like I said before, this is where I'm going to spend the most money. I don't want to half azz this part and wind up with a burnt up motor. The other stuff is no biggie. So what if my turbo takes a dump, it only cost me 100 bucks. It'll just be an excuse to buy a bigger one. At least my car will still run.
Yes I know that my I/C core is small, but it will do for a low boost setup like mine. It flows through the 16" side, so there will be very little pressure drop. As if that's not enough, I already have a water injection kit that will lower intake temps more than enough with this small of an I/C. Besides, you know how small the opening is in the front air dam. Maybe 4"? How much air is really going to flow over something that's up behind the bumper? We'll see, I may go with something larger later.
10psi is a lot. I hope you plan on lowering your compression ratio a little. Maybe a thicker head gasket or something. I'll probably do this too next spring/summer when I yank out my motor for a rebuild. Maybe then I'll consider upgrading to 10+ psi.
