What should I get with the 3s?, before they put it in Options

[Doge]

Hey all. I am about to get down and dirty with the 3s swap and I have some questions about what items I should get right now and what items can wait.

Turbo Timer - Kinda confused about this one cause I know its a really beneficial thing for your turbo to have one, but do stock turbo'd engines have them? If not why not? I thought these things were pretty necessary unless you want to sit in your car for a spell before you turn it off and go do what you gotta do.

Boost, a/f, and EGT gauges - I know I want the boost and a/f gauges, but how good of an idea is it to get them? Will the boost and a/f need enough attention that its prudent to get gauges for them? And about the third gauge (I put EGT because thats the one I was thinking of getting based on posts that i've read) ...of the other gauge options which one is the most important to be able to monitor? EGT, Oil Temp, Water Temp, Oil Pressure, etc, etc. Which gauges will be used the most?

SAFC2 Engine Management - I know its beneficial for proper tuning, but do you guys think its pretty necessary? Will it help with reliablity, gas milage, etc.? What im trying to say is, is it something that i'm going to need to get soon or is it something that can come way down the road?

Been searching endlessly for these answers and I figured there's no faster answer than to ask you guys. I'm just alittle paranoid about doing this thing right so thanks for any info.


P.S. If theres anything that I didn't list that would be a good idea to get please feel free to list and explain.=)

A/f is pointless. EGT would be very good, boost, oil pressure is vital, and water temp would be good. The 3s runs pretty hot. But the 4g63 on the eclipse runs hot too. Both run can get up to 200 degrees and that's normal.
DO NOT GET THE S-AFC!!! It's a device that's tricks your computer into how much air the engine is sucking in and you will risk running very lean. It doens't work too well with the AFM unit. I have a link that talks about this. Let me find it.......Well here is an excellent write up. http://www.mrcontrols.com/primers/power.htm
Anyway, your stock ecu will take you as far as you want to go(power wise) until you upgrade the turbo.
Get a turbo timer if you don't feel like waiting for 40 seconds to get out of the car.
Replacing all of the gaskets and timing belt would be a good idea. But then again, the engine will only have 40,000 miles or so. So it's up to you. I didn't repllace anything. I beat the **** out of it for a year, timing belt and compression are all good.
