The best mods for the money.

[20mach03]

So i have a 2003 mach 1 and i would like to make more power. But, its my daily driver so i dont want to do anything that will hurt my gas mileage, also i dont have alot of money so... Im looking for somethings that are cheap but will help the power.

It already has a catback, k&n cai, and a raised shaker.

anything would be helpful.

the basis intake, spacers, exhaust, short shifter like MGW, and a tune and you'll be set for a mach. I would start with the basic intake such as JLT RAI and then get a custom tune and you'll definitely feel the difference

Raised shaker, as in an intake spacer or is the shaker itself the only thing raised?

What's not a lot of money? I've done a lot in a short time with very little money. The key I've found is getting used parts.

An Off Road x/h pipe needs to be your next mod. Pypes, MAC and UPR are all under $200.

If you don't have an intake spacer, MMR has a 1/2" for $99.

K&N isn't the best but it's ok I guess(JLT RAI is the way to go). What CB is on the car?

Also, are goes just for set of the pants, track, street? ONce you buy some mods you'll need an SCT tuner!!!

its just a raised shaker. and im just looking to feel the power when im cruising with my buddies etc. its not really a drag car.
Also when i bought the car the duct that goes from the shaker to the filter is gone. is that piece worth looking for a used one?

go to mach1registry.org and look in the used parts section, im sure there's a cold air and cat back there. also check out the ROY's intake spacer. its worth 12tq in the mid range, not much on peak hp, but the mids are what get you there. also, if you can find a used mid x/h/ prochamber setup itll be worth it.if you get mid's you'll need a tune.
btw congrats on the car.

I agree with everything except I'd add gears, 4.10's IMO if fuel economy is a huge concern. 4.30's if you can live with 22-23 on the highway. Best bang for the buck mod on a Mach IMO. I got mid 20's with 4.10's all day on the highway in my Mach. Add in mid, tune, JLT RAI, short throw shifter, maybe some H&R's and you will have a legit 12 second car on your hands if you can drive.

i concur, lol... i knew i forgot something. yeah, gears dont kill mpg's in the mach's. a heavy foot will with gears only.

 

[RcodeStang]

Weld in sub frame connectors, shifter, used long tubes/x pipe, tune.

Gears def!

So i have a 2003 mach 1 and i would like to make more power.

Good bang for the buck power mods are:

-March #1158 fluid damper and water pump pulley
-Cobra R alt pulley
-Cobra R hydraboost pulley
-96-98 cobra intake cams, degreed to a 108LC
-Off-road X and good mufflers


On a stock longblock engine the following mods will do little-to-nothing to increase power: throttle bodies, CAIs/RAIs, intake spacers and shorty headers.

Aftermarket coils and raising the shaker will add no power at all.

Doesn't the cobra r alt pulley prevent the alternator from spinning fast enough to charge at idle? Just curious, I'm considering this mod as well.

I have a few csutomers running them and none have charging issues.

Thanks so much, What's the common gains from these? Any dyno results from just the pulleys? Those add up $$$ could get a West Innovators for a little more.

My car doesn't charge with tho's pulleys on, once you bring car up just off idle she starts charging.

 

[clc44]

Got ya, did you notice any gains?

 

[na svt]

Those add up $$$ could get a West Innovators for a little more.

and the innovators west damper frees up no power.

If you have concerns about charging you can keep the stock alt pulley.

The march damper and water pump pulley will free up about 10rwhp, the hydraboost pulley another 3-4.

 

[Bmeagher]

I do have a before and after dyno results, March damper, Cobra R Alt & P/S pulleys & new COP's. But the before dyno result, a COP was causing power loss in TQ. So actually it's not a good comparison.

^ how much did it make anyways?
