and, uhhh...about how much will this damage the wallet area of my pants??

I don't recommend a K&N air filter, those things allow soooo many dirt particles into your engine it isn't funny. Stick to a regular paper OEM air filter box, they don't provide any additional HP, that's for sure, but they're the best at keeping the engine from inhaling dirt.

There are not too many affordable options for increase in HP in these Rodeo's, main thing for optimal power is keeping them stock and in-tune.

and, uhhh...about how much will this damage the wallet area of my pants??More than you'd think. First you'd have to put a "98 and up" DOHC 3.2L or 3.5L in your Rodeo, then buy the supercharger. No one makes a Supercharger for the SOHC 3.2L.

depending on how in depth you want to go, you can deck the heads and grind the valves. You can do this to a stock engine and gain probably 15-20 hp depending on how much you take off and the angles you grind the valves. That is the old fashioned way, but it works.

Like the others mentioned, not much. Why would you want to add HP to a '97 4WD? To see if you can acheive single digit m.p.g. instead of mid-teens?:lol:

And there's isn't much to the structure of this type of vehicle that could withstand the stresses of extra power for any length of time.

Having said that, my recommendation for you to add HP to your ride is to drop a trailer on your receiver hitch. Atop that trailer would be a nice new 14' freshwater fishing boat with a quiet 15 horsepower 4-stroke engine. That would be a great way and reason to spend $3900 instead of modifying/upgrading the engine.

My :2cents: :wink:

about $3000 after is is all said and done.

ok...right.:rolleyes:

and while your at it you can custom fabricate new bigger 3" headers, port and polish, bore out the cylinder heads +20, re-calibrate the computer,etc. etc. etc...

so realistically, nothing...

mmm-hmmm, looks like I wont be getting a supercharger...guess I'll just add a calmini filter, which will give me what, 10 HP max?

about $3000 after is is all said and done.Is that including the new engine?:evillol:

yeah, if you're using their test vehicle, on the day they tested it, using the gas they tested it with, etc...

none of the "adds horsepower" numbers they give are realistic. it's as tested*

it may give you 3-5 if you're lucky.

the engine will cost you about $5500 from the dealer. (the dealer only pays $2500...go figure:rolleyes: )

hmm, so would you recomend adding an aftermarket air filter for added HP or is it not worth the $160?

Not if the type you get sucks in more dirt then air.

i wouldn't spend $160 on an air filter. save you money, get a cheap one off of ebay--then fab a heat shield to keep it from sucking in a lot of hot air from the engine compartment.

k&n filters are nice, but now you're paying for the name anymore. there are a lot of aftermarket cone filters that work as well as k&n does. i think there is one that is green and only half the price.

the engine compartment is full of dust and heat, so a cone filter is going to pick that up pretty quickly. i have an idea for a scoop for the hood that might be able to use the existing air box. something that is like this:http://i39.photobucket.com/albums/e152/directoryphoto/vehicle/Mac4x4005.jpg

now if i could just find the part number for the scoop (off to the mitsu forum i go) i could fiberglass it into the hood. http://i39.photobucket.com/albums/e152/directoryphoto/vehicle/Mac4x4003.jpg

I just dremeled out the front of the stock airbox and removed the rubber sheathing around the left headlight to let cold, outside air into the airbox. This gives me the same extra pep I got from a cone filter without the drawbacks of using an exposed filter. Plus it's quieter than the cone filter.

that's a great idea!

that is a good idea...have any pictures of that?

I don't have pics cuz the thing is, it looks completely stock! You really can't see the opening at the front of the airbox unless you really know to look. To me that's a benefit. I started by cutting out a small rectangular area (3.5" x 1.5") and started expanded it till I got the right balance of pep and gas mileage. I use a K&N panel filter with no worries cuz it's protected by the air box.

A warning about cone filters: I went with the modified airbox method cuz when I used a cone filter (calmini intake), it would cause my truck to ping. After much discussion on the 4x4wire forum, it was determined that the velocity of the air entering the intake was the culprit. The oem airbox has lots of kinks and round-about air passages to reduce the speed of the air coming in. Anyways, I know lots of people with the same truck have cone filters without the ping problem, but it just wouldn't work for me.

And besides, having an exposed filter element in the engine compartment just didn't make me feel confident. The airbox on the other hand, both protects the filter and serves as a heat shield. Plus, the cutout and removal of the headlight shroud ensures that outside air is entering the airbox, rather than the hot engine air. BTW, I did remove the elbow that wraps around the front of the airbox and goes to the driver side fender. I just taped up the remaining opening. No need for that elbow.
