Okay, I've reworked everything out. It's definately going to be an S5, and the only two mods I really want to do the engine (leaning towards turbo now), is the cat back exhaust, and cool air intake. Now because of this, the PSI will raise about 2-3 psi (right?) so I have my boost increase that I'd like.
Now because of this, I've been reading more and found information about needing more fuel delivery, so a Halboro (forgive me if my spelling sucks) fuel pump, is definately in order, but what about the fuel cut? Do I have to worry about that also?
And I say now, I just, and only just, want these two upgrades for performance. A $500 exhaust system in the US, will cost me about $1400 in Canada :P

get a FCD if you are going to do an exhaust. Also you might want to consider how difficult it is to find a series5 especially in canada. If you come across a clean S4 for the right price, don't exclude it just cuz its an S4.

Oh, thanks. Must have missed that information. Then I guess I'm going after an S5 (89 - 91 right?)
Don't mean to sound like an idiot, but you can't learn anything if you don't ask questions. Thanks for the help.

actually an S5, I could buy about four of them right now, just the prices are so expensive ($4000 - $9000) I've found.
An Rx-7 is an Rx-7, and hell, I even find the first gen 7's very cool ;> Sort of a classic Rotary, and everyone I've seen, especially from their age, is well taken care of. The only thing that is alluring to me though, is the engine in the S5. I heard it runs the best because of the ideal weight of the rotors.
Just doing homework before I start investing a lot of money. And next question, if I were to say, remove the resonator (if there is one) and replace it with a straight pipe and replace the muffler, would that be an effective way of gaining a few HP?

I guess. My real plan for some extra HP. I have 2 12" subwoofers, two amps, wiring, custom boxes (already made for the 7), and other items I want to stuff in place. So I want to make up for the weight I'm going to add with some extra HP.
But, some questions about the fuel cut defuser,
1) How does it work
2) Can I make my own?

unless youre really good with electronics and crazy stuff like ohms and volt and wiring and all that then you cant....it does stuff with signals and im not about to try and explain/butcher how to make one
it works by sending a different signal to the ECU i believe...or maybe to the solenoid?

I see. If it's just modifying the signal, a delayed signal might be a little better in that respect. So, adding a cat-back exhaust is going to require a bit more research just to use it, but can I get away with adding just the cold air intake?
