Performance Upgrades

Hello Jeepers,

I own a 2005 Jeep Wrangler TJ Unlimited. Everything is stock.
First, I am looking to do some general upgrades on the engine to enhance performance.
Second, I am interested in adding some stuff to the exterior such as body armor, bumpers, a winch, light guards, etc.

I plan on upgrading it in stages and am trying to get a list for stage 1. My budget is about $2500.

Moved to TJ Tech.

As far as performance, there are no cheap and easy bolt up upgrades. Engine swap, stroker or forced induction are the ways most go. Internal engine work can help also, but cost benefit balance there is questionable.

As far as all the other stuff, peruse this section. Use search function if you need to. There will be hundreds of threads on each of those topics. If you have specific questions then you can ask them, but at this point you need to just read.

General upgrades consist of a tune-up.

Don't waste your time on intake or exhaust mods unless you plan on doing head & cam work.

There is a relatively recent thread about armor priority, good stuff, find it. I suggest aluminum to minimize weight gain.

Fill out your profile first. If it's an auto, regear it even if you have small tires.

I'd save up money and research. $2,500 won't get you far with this hobby. Start small. Figure out where you want to be in the future and plan accordingly. Nothing worse than spending time and money and ending up trashing ur original plan because you want to go bigger. Surf the threads. This place is a goldmine.

Join a club and wheel that Jeep. You will figure it out real fast what might be needed. The I6 engine is a boat anchor; not a great platform for any enhancements. Being practical; proper gearing for your wheel size is all you really have to play with.

Reducing weight will help but you want to ad armor. Obviously armor is important. Much of what you do to improve off road capability will reduce the performance (handling, speed, mpg). Re-gearing is how you make up for the power loss, esp the loss you will experience if you go with larger tires.

as others have said don't bother with the "horsepower" bolt ons. For what it costs exhaust, intake, filter, throttle body stuff is no where near worth it. Best thing you can do right now is clean your IAC and throttle body, put in some double platinum or iridium autolite plugs and put in a quality MOPAR or AC Delco air filter. Check your ODPA for wear.

Wranglers with the 42RLE transmission come horribly geared from the factory even with the 30" tires. Most guys go with 4.88 gears when running around 33" tires.

Thanks, I will look into that then.

Yep definitely avoid 1) K&N air filters, 2) throttle body spacers, and 3) Cold-air intakes. The K&N passes WAY too much dirt into the engine, the throttle body spacer does nothing when placed under the type of throttle body modern Wranglers have, and the CAI is great in theory but does nothing for the TJ in reality.

When you have a choice, buy American.

I would suggest a modest lift and a front aussie locker, bigger tires as you can afford them.

first i'd say rocker armor, then engine skid and steering box skid.

My personal choice of armor installation order is oil pan, gas tank, rockers, steering box.
