blown 4.7 engine

So I destroyed the engine in my wj. I'm debating onwhat the best option is to replace it. Should I go to the junk yard and get a low mileage engine. Should I look at jasper engines or another type of crate motor.

Reman.. If you plan on keeping it. The used motor at the junkyard will cost you almost as much and not offer the warranty that the reman does. With a used motor you really have no idea how well it was maintained. As long as you go with a reman from a reputable company you will be happier 2-3 years later.

I faced the same question myself and installed a reman (a 4.0 i6 from Grooms engines) after looking at all my options.

Crate motor for a 2002 wouldn't justify the cost for me. I would go with a low mileage junk yard engine.

Jasper warranties aren't worth the paper they are written on.

That low mileage junk yard engine will probably cost you close to 2k without install. For me it was only a $400 difference.. Installation cost was about the same between the two options. I think I had about $3600 in it by the time I was done with it and now have a 3 year unlimited mileage warranty on the motor (and I know that it has been maintained well Because I have owned it).

The problem that I have with remanufactured engines is the fact that the engines are rebuilt with the cheapest of everything. As for the 3 year unlimited mileage warranty, it sounds great until you try to make a claim. Hope you haven't been doing your own oil changes.

Work with a well known and established local installer that also sells them. My installer just told me to keep the receipts and that they would assist if needed. He has lots of customers that change their own oil and in the few issues that they have had with these engines Grooms has taken care of them.

I heard that about Jasper too.. That is why I didn't go with them. A simple Google search for comments on these companies will show you the number of complaints out there. At the time, Grooms is one of the largest suppliers and negative comments were minimal.

I know nothing about Grooms. Dealing with Jasper is nothing but a nightmare. I'm sure that Jasper means evil in some language. LOL

Install a supercharger on a 4.7 and the outcome should be about the same. LOL

I wish I could put a super charger in. But thanks for the tips. I think I have a lot more research to do. If I go the junk yard route my buddy would install and I would. Or my family friend own a garage and is a dealer for jasper so I sous find out what he woke charge me.

Sounds like a plan.. Good luck. Report back what you find/decide.

In my area, its around $1,500 for a junkyard 4.7 and they usually have high miles.

I'd never spend that much on a used 4.7 with high miles.

In my area the 4.7 out of a wreck pulls a premium price. Usually above 2000.

My friend that builds engines says the parts are expensive and it costs 2700 to rebuild one with all new parts.
