I have an 02 TJ with the 4.0 Liter and unfortunately it's at the end of it's life. I'm looking into getting a rebuilt engine but don't know where to look. Someone said Jasper has rebuilt engines, but I'm wondering if anyone has got one from there or any other site?

A rebuild is fairly inexpensive...plus you can upgrade components

get a reputable automotive machine shop to rebuild your much better than a Jasper

The advantage of finding a shop to rebuild yours is that it's so easy to stroke the 4.0. Get a 4.2 crank and 4.2 short rods. That turns your rebuilt engine into a 4.5 budget stroker. I think there's a company selling new 4.2 rotating assemblies because this is such a popular mod. The 2004 and earlier stock camshaft maximizes dynamic compression on this 4.5 budget stroker set-up.

Where are you located? Are you familiar with any machine shops in your area? Depending on where you are, there could be a well known Jeep engine builder close by.

If you have the ability to remove and disassemble the engine yourself, a machine shop will be able to rebuild it for less than half the cost of a Jasper. Also, we probably should be supporting our local machinists anyway.

jasper engines aren't very good

I have looked into the jeep specialty shops near me and none do rebuilds. They are the ones that actually recommended finding a rebuilt engine online. One suggested going used, but I'd hate to buy an engine that may have its own problems, and finding a used jeep engine with low miles is looking for a miracle. I've called several shops and most don't do rebuilds or seem like they don't want to do it. I have only found one that gave me a ball park estimate of $5000 to $5500, but they said they are booked until the spring.

Again, where are you located?

We are not talking about "Jeep Shops" that charge $5K to install a rough country "lift kit". We are talking about engine machine shops that have specialized machines to clean, bore, resurface and assemble engine blocks and cylinder heads. Shops that recommend installing a used or rebuilt engine are shops that do brake jobs and inspection stickers all day for grandma's Rav-4. Google engine machine shop in your area, or tell us which state you are in so we can point you in the right direction.

It cost me around 3K to rebuild mine, .030 over and name brand parts
Machine shop took about a month and a half, the good ones are usually backed up a bit on work

I agree. Rebuild, unless you have a rod sticking out the side of your block.
