Honda B-series turbo kits

Depends on the power and RPMs that the car will run. Most modern Hondas run high impedance fuel injectors. You can usually get up to 440cc injectors for fairly cheap. RC has started making high impedance fuel injectors larger than 440cc in the last year or so. If you want to run low impedance injectors, like 450s from a DSM(extremely cheap). Then you need a resistor box or you can wire individual resistors into each injector pigtail. I would look into running something at least the size of a 50-trim. Often kits designed for the 1.6l motors will run a smaller exhaust side like a .48 T3. Turbo choice will depend a lot on how you want the car to respond, are you going to rev it to 8500 all the time or do you want it to start spooling as right away for auto-x use. The GT28RS aka Disco Potato used in some of the Edelbrock kits makes a few pounds of boost pretty much instantly from just about any RPM and then slowly spools from there like normal(a lot of dual ball bearing turbos do this).

Doing Hondata on an OBD2 car can be a little spendy though, you first need to convert the car back to OBD1 with a conversion harness and get a socketed OBD1 ECU.

I'm pretty sure the guy who wants the turbo kit for his Si would be happy with the increase a basic turbo kit would have. He knows it won't be that fast, he just wants to make his car at least respectable. He'll be on the stock engine for awhile, basically.

What are some basic things he could do to prolong his internals with low boost (6-8psi)? I'm talking about things like a thicker headgasket, or a rising rate boost sensing AFPR, etc

Rising rate FPRs are called FMUs and are a ghetto way to go. The stock internals should be able to handle 6psi-10psi fine with a decent tune. The reason to goto something like Hondata and a bigger fuel injectors is to get safer tune. The ways that kits like the Turbonetics and Edelbrock handle fuel/timing are much safer than the old FMU approach, but not as perfect and reliable as doing a Hondata style setup. When you install any kit though, you will want to make sure that whatever fuel and timing system it comes with are actually working.
