New jeep owner

[Ovedz]

Hey guys I'm getting a jeep this week. I need some pointers on what I should look for when buying it. It's an 02 renegade 92k miles

Welcome to the forum.

02 is a good year. Have it checked out good like you would with any used vehicle.

Performance upgrades ???
Its a Jeep not a Mustang
Keeping maintenance up and gearing are about it

Just because your comfy with a v6 doesn't mean there's people out there that want a little more juice. It looks nice, now I want to make it sound nice, not by just adding a new exhaust system. When you live near the Catskills it helps to have more kick when ur scaling mountainsides.

There are a good deal of snake oil upgrades that you can sink your money into if you choose... but really nothing that performs and lasts.

piston rings are to high on the pistons to handle any boost so forced induction is out of the question, IIRC i've heard that the ECU will learn around something like a jet chip and you'll be back to stock tune in no time, no company makes performance parts for the 3.7 (not even ignition coils), i think the name of a company that can actually tune the ecu is "B and G", (someone correct me if i'm wrong) and as tom said most "cold air intakes" aren't that they are a Short ram intake=hot air intake, so a good set of headers from JBA and a cat back are your only "power adding" options and if you just want the sound go for it, but IMHO the payoff in added power isnt worth the money for an exhaust on a kj, but if you're dead set on more power do a 4.7 swap.

Sorry just telling it like it is
Sure you can add a different muffler for sound but not going to gain much real world HP, just sounds like you do.
Only real thing to do if going bigger tires is to regear
The one company that made headers for the KJs even stopped making them
so..............

Well, there is always the 4.7L swap. Out of that, the only change they are made for are off-road mod.

Re-gear.

The ECU doesn't learn around the Hypertech, and it made a HUGE difference in my Jeep.

How much power did you get?

 

[tjkj2002]

Maybe 5-10hp if any at all,mostly effects the trans for better shifting by correcting the speedo and altering shift points.

The transmission shifts soooooo much better. According to hypertech it's a 25hp/25tq gain. I'm sure that's not true but it's significantly faster and worth it to me.
