yea i have a 97 wrangler with a 4 banger in it. im wanting to do a couple things to give it a little more power... ive heard and read on here that the 6 cylinder throttle bodys fit on these...is there any specific model that it has to come off of? i seen one that said it was off a cherokee but said it would fit a 6 cyl. wrangler...so does this fit the 4 cylinder?
im also wanting to get like a pace setter header or something more aggresive because mine is leaking and i have to replace it anyway...any suggestions on what brand?
also plan on getting snorkel and new exhaust...any input would help......thanks
The TB off of any 4.0 will work. You will only gain power on the top end, ie...freeway with a WOT and then it's not much. I notice on one hill near my house I do not have to downshift as soon as I did before this mod. Not a great mod but for the price and ease of install, it does help.
99 SE with less than 43K on the clock and a few mods......
They may be putting out twice the horsepower with the boost and higher compression, but they sure aren't running 87 octane to achieve that power! If you want more power one option is to have your head milled down to decrease the size of your combustion chamber but that will necessitate running higher octane fuel, which of course costs more and if you mill too far then you will get stuck running race fuel or octane booster in every tank. You can also try to find a more aggressive cam if they are made for your engine.
It must be a lot easier to find 93 octane in Chicago! Premium fuel here is only 91 octane. If you want anything higher you have to go to the specialty stations that sell the race fuels and those are very very very few and far between! It would be great if the higher octane fuels were more readily available as I will be lucky to be able to run 91 octane on the 289 I'm currently building to go in my '66 Mustang and even then I would be even more lucky to get 10mpg with it! Haha!
cold air intake
full exhaust including high flow cat.
throttle body swap, be sure to bore the intake manifold so you get your flow.
throttle body spacer
decent spark plugs, wires, cap rotor, fuel filter.
all in a combo would help you get as much air in and out of your 4 cylinder. without major mods there isn't much you can do.
Prices the ebay way.
Header = $120 (next year)
Hi-flow cat = $20 (Later on)
Cat back exhaust = $100 (Have it)
Cold Air Intake = $40 (Have it)
Throttle Body Spacer = $20 (Didn't make a dif)
New Gears = $300 (Christmas)
Squeezing every last bit of power out of a 4 Banger = Priceless
These are all actual prices I paid, or that I am going to pay
Be careful with the ebay items, I've read to many posts with the cheap headers cracking. the tb spacer I've got one on a 4.0, and didn't notice anything either. And every $40.00 intake I've seen has the filter right next to the engine, kinda cancels out the cold air part huh? And please tell me where your getting gears for $300.00 I'm in the market if they don't whine louder than hell.
