if i get downpipes for my 93 RX7, will i need to get a computer to comply with it? The current mods are fluidyne radiator, Apex N1 exhaust, and AST. and if i need a computer what kind and what do you recommend?

 

The usual setup is intake, cat-back, downpipe then ecu. You should probably get one soon.

 

I think if you were to get downpipes, then yeah you'd probably need a computer.

But seriously, you're on the borderline where depending up on the condition of your fuel system, some people actally don't need on but it's good to be safe. Most people here will say Pettit Unlimited, I'm sure. They're like robots.

 

M2 is known to be safe yet conservative. KD reccomended me to go there.

 

As long as the boost is kept at 10psi, you'll be fine.

 

You can bolt on a 30" exhuast if you want and what ever else there is for this car. If it boosts more than 12 psi your in trouble.

 

im just trying to put on the reliablity modifications and some minimal performance mods, i want my car to be reliable yet still i want to run high 12s to low 13s.

 

As long as you still have the main cat it's not a problem...ask Rx7.com, Rotary Power, Rotary Performance, any good RX-7 shop. As long as you have your main cat you wont be in danger. Once the main cat goes...you will creep to death
