4.0 Crate Motor ??

GM, Ford, Mopar, all have crate motor programs. My '95 4.0 is starting to age and was wondering if there is a place to get a 4.0 crate motor?

Any help ???

Thanks,

Don

not that i know of, but for the price of an engine swap, you could have a stroker kit done, which will basicly give you a new engine with more power.

With a stroker motor, do you need to change the injectors?

Jasper Engines sells 4.0's with a 3 year 36k warrenty or so... as do a few other companies.

Is there anything wrong with your engine? Does it smoke, tick, knock...? Generally 4.0's will last a long time, so thats why I am asking.

well my local dealership does, 3000 for a rebuild (install, labor parts, all inclujsive basicallyu) and 5000 for a crate motor... I intend to just purchse another motor from the wreckers and might stroke it if i can figure out a way to do it without having to use 97 octane or whateever redicously high octane level they insist on least for some of em... so it depends on what you want to do, oh prices i qouted are canadian. I will prob see what it costs for a crate motor and ill put it in... gotta be like 1500 cheaper at least

For the $$ you'd have in a Jasper (or like) or a crate motor send your existing motor off to get rebuilt (ie. stroker). You'll be a lot happier in the end... (I know I am)

Where is Jasper engines located, and will they do a stroker engine? To answer earlier question, motor runs good now, uses no oil, just in the mood to tinker I guess.

not to be an a$$ but if your gonna tinker why fix something that aint broke?? if your gonna do that much (time and money) why not upgrade insted of just replace?? (ie. stroker).. i mean no disrespect and do what makes you happy its your ride and money just dont make much sense to me is all

There are some good simple strokers out there, check here first:
http://www.jeep4.0performance.4mg.com/stroker.html
He lists lots of options, and fairly inexpensive too.

As others have said, if you want to tinker, the 4.0 is hardly a component in need of it, better time and money would be spent on armor, diffs, axles, etc, the 4.0 is legendary in it's reliability, other XJ parts are not. If you want to do some underhood work, try an On Board Air or an On Board Welder, both are tinkerer type projects.
