1st congrats on getting your FX. I'll start by giving you a fair warning: Be very careful, this is an incredibly addictive hobby that sucks massive amounts of cash!

My recommendation: Prioritize your options since there are so many mods you can do to your FX. 1st determine if you're more into aesthetics (or audio) over performance (or handling) and vice versa.

$ = $1-250
$$ = $250-500
$$$ = $500-750
$$$$ = $750-1000
$$$$$ = $1000 & up
$$$$$$ = maybe you should consider buying a real sports car as a second car to fill your speed needs instead.

Almost all mods are (here's a new word for you:) DIY-able. Here's a list in the order I would do them:

Straight line performance:
1) Cold Air Intake/ Air Filter (Stillen, JWT, K&N) - $/$$ (DIY)
2) Z tube or equivalent (UR CF or Alum tube) - $ (DIY)
3) Plenum or Plenum Spacer (Crawford, Kinetix, Motordyne) - $$ (DIY)
4) Pulley (UR) - $$ (DIY; Pro install recommended)
5) Exhaust (Stillen, Custom) - $$$ to $$$$$ (DIY; Pro install recommended)
6) Headers (Crawford, DC, OBX, etc...) - $$$ (Pro install recommended = $$$$)
7) Hi Flo Cats (Crawford, Kinetix, etc.) - $$ (DIY; Pro install recommended)
8 ) Custom tuned ECU - $$ (DIY)
9) Transmission mod - TC / Valve body / tranny black box mod. My guess is $$$$ on cost (Leave this to the pros). brnjug is the man to inquire about this mod (I think this mod's absolutely necessary if you're serious about speed)


Extreme: Forced induction (supercharger, custom turbo)- $$$$$$ (Dont even think about doing this yourself)

Handling:
1) Strut Tower Bar (Stillen) - $ (DIY)
2) Lowering Springs (Eibach) - $$ (also Aesthetic) (Pro install recommended = $$$)
3) Wheel Spacers (H&R) - $ (also Aesthetic) (DIY; Pro install recommended)

Extreme: Light weight forged wheels & perf tires - $$$$$ (also Aesthetic) (DIY)

Braking:
1) Cross drilled/Slotted rotors (stock size) - $$ (DIY; Pro install recommended)
2) Brake pad upgrade - $ (DIY)
3) SS braided brake lines - $ (DIY; Pro install recommended)

Extreme: Big Brake Kit - $$$$$ (DIY; Pro install recommended)

Aesthetic upgrades:
1) Window Tint - $ (Leave it to the professionals)
2) HID bulb upgrade - $ (DIY)
3) Fog bulb upgrade - $ (DIY)
4) Clear turns/driving light bulb upgrade - $ (DIY)
5) Interior bulb upgrade - $ (DIY)
6) Grill - $ to $$ (DIY)

Extreme: Custom paint / body kit :?

Audio:
1) Custom Sub/Amp - $$ to $$$$$ (DIY; pro install recommended)
2) Front/Rear speaker upgrade w/ Amp - $$ to $$$$$ (DIY; pro install recommended)
3) MP3 player or Sat or DVD add-on - $$ to $$$$$ (DIY; pro install recommended)

This is only breaking the surface of what you can do..... anything is possible as long as there's enough money to support it.

Here's a detailed list of Go Fast Mods available for the FX35:

Approximate cost Legend:
$ = $1-250
$$ = $250-500
$$$ = $500-750
$$$$ = $750-1000
$$$$$ = $1000 & up
$$$$$$ = maybe you should consider buying a sports car as a second car to fill your speed needs instead.

Performance gain Legend:
MINIMAL = 0-5HP
MODERATE = 5-20HP
YRMV = Your results may vary

Almost all mods are (here's a new word for you:) DIY-able. Here's a list in the order I would do them:

1) Cold Air Intake/ Air Filter (Stillen, JWT, K&N) - $/$$ (DIY)
Upside:
- Performance Gains: MINIMAL through entire rpm range (YRMV). Opens up top end; Works well in conjunction with other 'breathe' mods.
- Increased sound/noise.
- Never need replacement (K&N boasts 1,000,000 mile life), just maintain by clean & re-oil. (money saved in the long run)
- Reported to increase gas mileage.
Downside:
- Increased sound/noise; K&N direct replacement filter is a good compromise option (much cheaper too).
- Maintainance required.

2) Z-Tube or equivalent (UR CF or Alum tube) - $ (DIY)
Upside:
- Performance Gains: MINIMAL through entire rpm range (YRMV). Increases flow of air by providing a smooth air passage to the throttle body & removing the sound baffle/silencer; Works well in conjunction with other 'breathe' mods.
- Increased sound/noise.
- Reported to increase gas mileage.
Downside:
- Increased sound/noise.

3) Plenum or Plenum Spacer (Crawford, Kinetix, Motordyne) - $$ (DIY)
Upside:
- Performance Gains: MODERATE through mid – high rpm range (YRMV). Increased air capacity over stock; Increases air flow to the cylinders, negates the restrictive front slope of the stock plenum; Works well in conjunction with other 'breathe' mods.
- Increased sound/noise.
- Reported to increase gas mileage.
Downside:
- Increased sound/noise; there were comments that the Crawford cast plenum is as quiet as stock.

4) Light weight Pulley (UR) - $$ (DIY; Pro install recommended)
Upside:
- Performance Gains: MINIMAL to MODERATE through entire rpm range (YRMV). A light weight under-drive crank pulley ‘frees up’ HP (lighter, smaller diameter than stock), allows the motor to rev faster/easier to redline.
Downside:
- There is a concern for potential premature crank bearing wear – Never proven; an on-going debate about whether or not the VQ is internally balanced and other mumbo jumbo.
- Concern for potential alternator strain

5) Exhaust (Stillen, Custom) - $$$ to $$$$$ (DIY; Pro install recommended)
Upside:
- Performance Gains: MODERATE through mid – high rpm range (YRMV). Increases exhaust flow; decreases backpressure, Works well in conjunction with other 'breathe' mods.
- Increased sound/noise.
- Can add to appearance (Custom/larger exhaust tips)
- Reported to increase gas mileage.
Downside:
- Increased sound/noise.

6) Headers (Crawford, DC, Borla, OBX, etc...) - $$$ (Pro install recommended = $$$$)
Upside:
- Performance Gains: MODERATE through low – mid or mid – high rpm range (dependent on design: equal/unequal length; YRMV). Increases exhaust flow; decreases backpressure, Works well in conjunction with other 'breathe' mods.
- Increased sound/noise.
Downside:
- Increased sound/noise.

7) High Flow Cats (Crawford, Kinetix, etc.) - $$ (DIY; Pro install recommended)
Upside:
- Performance Gains: MODERATE through mid – high rpm range (YRMV). Increases exhaust flow; decreases backpressure, Works well in conjunction with other 'breathe' mods.
- Increased sound/noise.
Downside:
- Increased sound/noise.

8 ) Custom tuned ECU (TechnoSqaure) - $$$ (DIY)
Upside:
- Performance Gains: MINIMAL/MODERATE through entire rpm range (YRMV). Custom program ties all of your mods together and ensures that the motor is running optimal timing & A/F ratios.

9) Transmission mod - TC / Valve body / transmission black box mod. (My guess is $$$$ on cost; Leave this to the pros)
Upside:
- Performance Gains: MODERATE through entire rpm range (YRMV). These mods will increase feel & transfer of power to the wheels and decrease shift lag.


I hope this helps. Now, I need to get back to my real job....

Now the scary and sad thing about this list above is that I have done it all, and some even more than once. So now what do I do?

We need a vendor listing. Or is there something like that already and I missed it?

I've had my 35 for 4 months. What kind of upgrade should I consider first? More interested in performance than aesthetics but don't want to start off too expensive.

ujmont,

Kudos for such a complete list of mods!

If I was paying attention and found your post sooner it would have saved me a whole lotta "searching".

Your list couldn't have been clearer, better or more helpful!

2 thumbs waaaaay up!
