newbie 2.5L performance.
 
ok i used to have a 2.5 in a 00 tj a few years ago, i had only the banks header and k &n filter. that was it, ok yea i had a stage 2 clutch and and so forth, well now i have another one it has a cold air intake thats it. i want to do the banks header, magna flow high flow cat and a nice muffler, i was also thinking about getting a throttle body spacer. and maybe a ecm chip. i was wondering tho, will a 4.0L throttle body bolt up and add more power? also has any one experimented with changed with bigger injectors? i am also wondering if there is anything else out there that i could possibly do to add more power and torque?

most of the power upgrades are not going to give you much power. a 4.0 tb will give you a little more power, the intake/exhaust/chip/tb spacer are also only gonna give little power gains each. i have a 2.5 with a catback from banks, aem intake, tb spacer and after installing a lift all the upgrades raised the horse power and gas millage back to stock. it was only 4-5 mpg gain and a little horse power.

eehhh
 
im only going to be doing a 2 inch and keep 31s here on long island there is no need for anything bigger. i just wanna be able to do 70 mph with ease. which is why i though of that and was wondering of there was someoe that makes bigger injectors to. but i cant find anything

Everything you listed is a waste of money. TB spacers do nothing but give shit looks with piss poor performance. Is headers really worth a couple horsepower for the price in my opinion, no there not! A new exhause system, if yours is in need of being replaced yes I would. Does all this work add up to a noticeable difference yes and no. People have different experiences and opinions. Just mine but sure most will agree.

Dont change the injectors, its not a diesel, no chips, its a 4 cyl, not a drag car. As for your cold air intake. Scrap it and get a OEM box, filter, and fittings from a junk yard off another jeep. Big waste of money and time!

If you want to burn tire, go fast and take corners sell it and buy a mustang! :wavey:


Save your money for a lift, tires, and lockers!

the injectors dont really help that much i installed some in my 4.0l and i think it actually killed a little power and dont get the tb spacer you should just bore your throttle body a little it adds way more power. i did that to mine

Yup I agree, everything you listed will be absolutely useless to your jeep
