New jeep owner

Just purchased my first jeep, a 93 yj 2.5l with a 3in lift and Rollin 33's. Wanting to know easy suggestions to get a little more power out the four banger without spending an arm and a leg.

Welcome to the forum. Not really sure about the four banger. I'll let the others chive in on that one.

Re-gearing is going to be your best option...

Poweraid throttle body spacer makes a noticeable difference in midrange power. Cheap and easy. Stay away from aftermarket intakes, those little motors like the stock setup with a K&N filter. Do you know what gear ratio you're running in the axles? My last YJ was a 2.5 with the mods mentioned above and 4.88 gears. It would pull up long grades at 65-70 but stocks gears and no mods meant 3rd gear at 55

How is the install on this product? Pretty straight forward? I may buy one myself after reading up on them on the web.

well souping up an engine usually isnt a cheap proposition. Especially with 33s and a lift with the 2.5. Regear would be the best option I agree, problem is it isn't a very user friendly process to replace the gears. If your exhaust manifold is cracked (very common in YJs) replacing it with a header (about 110 shipped) will return some MPGs and horsepower. Installing a throttle body spacer may add more power, I have one installed and honestly did not notice a whole lot of improvement but I have a 4.0L so it may be different for a 2.5L.

I would start by tuning up the jeep and making sure everything that can be serviced is properly serviced before undertaking expensive upgrades. At the end of the day throwing a V8 in it is the best option if you are up for something like that.

Thanks for the advice. I know the tires are dragging it down I may go to 31's once these wear down. I will look into the spacer and I am currently looking into all new exhaust with new header any suggestions there?

Welcome!

I know... you'll get mixed opinions, thats the joy of the internet!

But, we usually suggest not going over 31's with a 4 cylinder. The heavier 33's are a lot for the engine to turn, especially if your doing anything more than simply driving it to work everyday. Not much you can do other than re-gear your axles w/new ring and pinion gears to make up the ratio differences.

K well I just put my header on last week, took about 3.5 hours and few beers. I have limited experience working on anything so you can definitely do that. Installing the rest of the exhaust is a no brainer as long as you enjoy battling rusted bolts. Quality is key here, I recommend headers with the flex pipes in it, but honestly those are not a necessity I have a header without the flex and it's fine. Give it a good acetone bath and a few coats of high heat rustoleum and call it
