Just bought the car with a couple of mods I've listed below, but I was wondering what else can I modify to push more power?


Mods so far:
a g-force computer upgrade, centerforce dual friction clutch, fd fuel pump, bigger injectors (no sure what there are), 2-stage boost controler, boost and a/f gauges on pillar, tokico hp shocks with apex springs, performance pulleys(main, waterpump, alternater), removed air pump, no cat, hks catback exhaust, custom turbo inlet piping, removed abs

 

may want to invest in a fuel pressure regulator and gauge. Also when you installed your FD pump did you rewire it? I ask because all the FC's we've had worked on lately aren't getting 12v, they all get 5-8v. So we've rewired them for 12v constant.
Just want to make sure mine doesn't lean out.

 

Next- Dual alternator pully to run the fan without the air pump belt.
Will the cat go back in for emissions testing?
Have you replaced the fuel filter and fuel pump pickup strainer?

 

I have people around the area that will pass the emissions for money, but I have no clue about the history of the car.

The fuel pump was re-wired to the a switch on the side of the steering wheel, switch down when I crank, when car begins to start up, switch up for fuel pump.

 

That's how mine came too, but with the switch underneath the steering wheel.

 

Do a tune-up. Like plugs, wires, coolant flush, new t-stat (mazda OEM), brake system bleed, tranny/diff fluid change, oil/oil filter change, fuel filter, check belts and replace if needed. You would be quite suprised what a nice tune-up can do!

 

Ok, so you are adding more fuel via larger injectors and a bigger fuel pump. How do you plan to tune that fuel? More fuel doesn't mean more power.

You should get a SAFC and do some dyno tuning.

I noticed you have an ECU mod. However, unless that change is specific to your fuel mods, you might be not getting all the safe power you can out of your setup.

Maybe some stainless steel braided brake lines an some good brake pads.
