Alrite, my turbo situation is looking pretty good. As of now, it seems like I can definitely have it at my house by May or June 2006. I've been working on a file with just about everything I need to get for the full rebuild that's scheduled down the road, but for now, I plan on installing the kit, and running at 5 psi on stock engine.
This is what I have on my list of things to have while I'm running 5 psi:
AEM EMS (I know I don't NEED this, but I'd rather have it early)
Turbo Timer (HKS Type 1)
Boost Gauge (Greddy/Apex'I/Defi)
Fuel Pressure Gauge
Is there something BIG that I'm forgetting? I'm just talking about stuff that's good to have if I'll be running minimal boost, nothing involving the engine rebuild- yet .
And, I've read that I don't need to upgrade the fuel system, since the stock one is rated past 350 - 400 hp, but would it help me in any way if I got a Fuel Rail/FPR/High flow fuel filter now, instead of putting it off until later, or would it just be pointless?
Finally, about a boost controller, does the AEM EMS have the ability to function as one?
Your forgot..blow off valve, dual gauge pod :P, and Id reccomend getting any parts that are old changed so they dont cause any problems. And btw you could easily run 6 or 7 psi

^^True true! I totally forgot the BOV! I originally had the Drag kit in mind, then I heard about setup problems, so I decided on going Greddy- forgot they didnt include a BOV. About parts being changed, I was thinking about changing belts, what else needs to be done? I would run a little more boost if I had money in my bank, but the fact is, if the engine ****s up, I won't have anything to drive until I save up most of the money to rebuild.
Any word about the AEM EMS being able to function as a boost controller? If not, I've read reviews about the Apex'i AVC-R, and the Greddy PRofec-B, they both seem to be pretty good units, any opinions on which is better?
You'll probably want to change your clutch and maybe your flywheel as well. I would upgrade to a custom 2.5" exhaust once you get the turbo kit installed for maximum flow and exhaust efficiency.
That's a file I had a while ago, it's NOT the updated version, (GT server isnt letting me upload to it) About EMS working as a boost controller, no info?

For your temporary build, it would very much be pointless.
As for "good to 400 HP", I don't think so. Hondata did a study on the Prelude fuel pump, and I'm not impressed. If I were going anywhere near 350 HP (not hard for turbo), I would absolutely upgrade to a Walbro pump FYI.

Yes. Not only that, it features gear dependant boost settings and closed loop capability (IIRC). The AEM is truly a bargain for any serious turbo build.

^^Awesome. So I won't need to get my hands on a boost controller or anything. I know I can plug my laptop in, so is there any way I can load different maps in, depending on if I wanted to run 6 psi, or 12 psi? and, if the EMS functions as a boost controller, does it come with the valve hookup and all?

It would be best for you to read the AEM forums as much as possible. There is tons of wisdom there.
The AEM will control any solenoid you can find. The easiest one to find is the GM one. I've seen them on Ebay many times. Any boost controller will control any solenoid for the most part -- all of them are controlled by a varying PWM signal. All it takes is for you to wire the solenoid to the pin identified on the AEM wiring diagram.
You can run different pressure settings either by uploading different maps, or by configuring a switch on one of the available EMS inputs. I believe that the EMS allows available inputs to be assigned to cabin mounted switches, in which case you could have it switch boost settings based on that.
One other feature the EMS comes with is closed loop knock detection. It essentially has most of the features that the J&S Safeguard comes with. It allows both fuel & spark adjustment based on knock signal. Not only that, it has some pretty nice knock signal conditioning too, so it doesn't pick up noise.
The more I learn about the AEM, the more I am amazed. It is one really nice piece of hardware.

Just to update you .. . I just did a BUNCH of research into the AEM EMS system and boost controller ability. I visited AEM and spoke to the head tech, Chris, one of the men who DESIGNED the damn thing.
Contradictory to what everyone says ... DO NOT USE AN AFTERMARKET BOOST CONTROLLER!!!! use the EMS.
I recently purchased an AEM 3.5 bar map sensor (which is the same price as a 2 bar and just as accurate), a GM boost solinoid and a wiring harness for it (which AEM recomended as it can hold 30 pounds!)
Anyway, the EMS has ALL the functions of the APEX plus it can also do RPM dependant boost WITHIN the gear dependant!!! ITs also 1 integrated unit so you save $$ on wiring, install and headaches from complications. My cost for my set up = $250 ... if you do an APEX set up = 500 + 200 for AEM map sensor!!
Point of the story ... AEM EMS KICKS A$$ so use ALL of its functions... including the boost controller
