Dual won't do anything. Comptech doesn't do much.

Maybe 2-4 for total.

 

this blows, i guess id have to go turbo and cash out around 7 k. i heard that i probably need to upgrade my transmission too.

 

No the Transmission does not need to be changed as it is one of the best out there. The "S" is a very difficult and expensive car to add power to. It all depends on what it is you are looking for and what you plan to do with it. For all out whp you could easily spend $20K or more. If you just want better throttle response with just some mild gains in whp & tq than your costs will be far far less. I have always looked at the "S" as more of a road course car rather than a street racer where you soot off the line and just go streight. With that in mind I wanted more tq & some medium whp gains and put more into tires & suspension. SO you really need to decide what it is you are wanting from your car.

 

Get gears!!!

 

get some suspension/chassis stability mods and some decent tires so although you might not be fastest in a straight line, take them to the corners where balance really matters.

 

just watch out for the mazdaspeed 3....

 

I dunno ... the new Invidia dual is 70mm, it's supposed to give like a 5-7whp gain (consistent with the T1R 70R Sparrow).

Don't mod this car into being a drag car unless you want to go balls out, it's quick in the quarter but not really built to be a drag car, you have to change the diff housing and gearing, not to mention add at least 100whp, to be competitive with most modded street cars in a drag race (i.e. run 12s).

 

How much would and AEM EMS help me. its only about 1000$, figured if it would give me some performance boost i might as well get it.

 

AEM EMS can give you gains, but know that you are going to lose some of the functions of the factory ecu.

 

If you want full power go turbo.

SC at 5 PSI is a nice bump up but you still wont be blowing out the newer cars out there.
