I want to build a 4.6. There are quite a few of parts I will need to upgrade, plus the machine work I can't do myself. My friend built one a few years ago and his total was about 3900 including his injectors.

I'd need to buy junk 4.0 and piece my build together.

Would a crate stroker be worth the money or should I just take my time and learn a new realm of modification I have been reluctant to explore?

If you dont have the tools,time,knowledge of how to assemble an engine the answer is buy a pre assembled crate engine and install it. No fun having a pile of parts that you cant make work sitting in your garage. You have a garage right?

I don't have all the tools but I have lots if time. I've learned a lot already about the build and everything involved and it all seems straightfoward. I know a guy who built one, too. I read about someone who bought parts individually, not a kit, and the overall cost with the core of his old one was less than $1000. Since I have a 2.5 under the hood, this build might be worth it.

In reality an engine swap is a better move. Just the swap to a 6 is a big project. Do so searching. A V6 or V8 from a TBI GM is a cheap high power alternative.

Haven't done it myself but the consensus seems to be that swapping from a 2.5L to a 4.0L is MORE difficult than many of the common V8 swaps, and that if you're going to swap you may as well get the V8 for the trouble.

I never rebuilt an engine until I built my Stroker. I took it on as a hobby, my TJ was far from my DD (it didn't even working brake lights due to a faulty turn signal switch for over a year). The extent of my work before the build was installing a 2.5" lift and replacing the clutch. I ordered this DVD from BoxWrench Media, high production quality and worth every dollar to any novice engine rebuilder, it walks you through every step of a rebuild. However, I took the 4.0 out of my TJ and stroked it and it has been running damn strong ever since. I was deployed 2008-2009 and had a lot of time to plan my build online and planned it out for over six months before I got home to start ordering parts. Three years later and I still have yet to tally the receipts but they are all still in an envelope for my curious self when I get the curiosity and patience to go through them. I do know that the machine shop was well over $2k.

Don't forget to check out JeepStrokers.com, and use my JF username if there is a referral. If you have any questions then shoot me PM.

The challenge is one part of the deal I'm really looking fwd to. Besides, a V8 would be a real gas guzzler, no matter how you build it. My friend has 350 tbi and gets 12 mpg, same as my 2.5. This thing is my DD so i'll build the thing then do a swap when it's finished. I just think it's funny how all those other people try to steer others away from what they want to do.

A guy in my club is a machinist and can practically do that stuff free! I'm looking at money going only into the motor and parts. Tomorrow i'll be pricing all that together and comparing to crate. But the reason i started this thread was to get feedback regarding costs.
