Mods and noise
I know that installing an intake and DP and cat-back will increase the noise, but does it get really loud? I still want to sound healthy with out overpowering sound of a race car.

They offer good performance but they aren't as loud as most of the single-tip exhausts. Racing Beat and M2 both have very good dual-tip exhausts.

Well the 7 I got already has a greedy cat back system on it, so I have no choice in that, but I was thinking of adding a blitz intake and an m2 or pettit DP. Is that ok? I've done some searching and see some controversy on wether or not you can do this on the stock ESU. I want to make my 7 more reliable, not kill it.

You will be ok if you keep the boost under or near 10psi. I got the m2 downpipe and it is great. It is not as hard as the others to install and works really great. Made of SS and 3". The only thing that really keeps the noise level down is the cat and cat back that you have on the car. So keep the stock cat and if you want a quieter sound then go with a rb or m2 cat back.

Well, if you want to keep it reliable, keep the stock intake. Replacing the intake doesn't really help reliability, however you should be fine with adding a downpipe.
Just keep an eye on your boost (if you don't have a boost gauge, get one before you add the downpipe) and make sure you are not going too far past stock levels. You will be fine around 10-11 PSI. Some people have run higher levels on the stock ECU, but I wouldn't recommend it.

Do I really need a boost gauge if I'm not racing? This is just a fun car for me. If I'm not abusing it, shouldn't i be ok with just those 3 mods? I read that the stock air box is not good, that's why i was going to replace it.

The stock air box is fine. It's a little restrictive, but adding an open air intake like the Blitz can cause the air pump to fail prematurely (since it has the possibility of sucking in warm engine air at idle or stop-and-go traffic).
What did the car come with already on it when you got it?

a boost gauge is a useful additional to a stock RX7. It can be extremely helpful in picking up problems before they get too serious. On a slightly modified car, the need to monitor your boost levels increases.
An accurate boost gauge is a must purchase on most peoples lists!

Ok so I see that there are different sizes of gauges and different monting locations. What is the easiest and least expensive. So is having a boost gauge, downpipe and cat back a good start? This car is all stock with less than 30k on a new engine and turbos and brand new auto tranny. I can get a slightly used blitz intake for 220 bucks shipped. it sounded like a good deal to me....don't you think?

If you are wanting to keep it reliable, then here's what I would do:
1. Add a boost gauge and an A-Pillar gauge mount
2. Replace the stock plastic AST with an Aluminum AST
3. Replace the pre-cat with a downpipe
4. Do the Fan-Switch mod
Sounds like you already have an aftermarket cat-back on, so that's about all I would do to it if you are looking to make it reliable.
Now, if you are trying to go for performance, that's a different story.

add an all aluminum radiator. Stock ones have plastic end tanks that are known to crack and leak coolant (mine certainly did ) Also, with an aftermarket intake you free up a little too much and the problem is not more air, the problem is boost. If you have a way of keeping the boost under 10psi (a boost guage lets you know what you are boosting at) then you are ok. Most people see it as a way to over boost and blow a motor.
