i know the 6.5 turbo diesel is not known for being a power house by any means, BUT i was wondering if anyone has tried, thought about trying, or succeeded in puttin a 6.5 in a yj. im looking at doing a off the wall swap and thought this may be cool. i would think a 6.5 weighs just a hair more than a 350 small block, and ppl do that swap all the time. so i figure a little frame beefin, this would be fairly straight forward. any insight?
The 6.5 is a boat anchor. It was crap when it left the factory and will be crap when its in a YJ. The 4BT would be a better option if you want go with a diesel and hasn't been done enough to be considered "common". But if you have money to burn, and just want to do an engine swap go for it. Just don't consider it an "upgrade". I work in a fleet shop, and have quite a few of the 6.5's still in service. And after a few years dealing with them, I'd rather have a 2.5L in a YJ.
You would definately feel the difference in power, but with all the other better options out there, I don't know why you would want to use the 6.5. If it was a good motor, a lot more people would be swapping them, and there would be a big aftermarket for them. The 6.5 is anemic at best. Its reliabilty leaves a lot to be desired.
Not sure what motor you have right now, but I wouldn't expect the 6.5 to be much, if any better than a 4.0.
i thought it would be the cheapest diesel swap i could do is why i was thinking it. i figured they would be pretty plentiful since the military used the na version of them along with the 6.2 but i could be mistaken
The 6.5 is a piece! I wouldnt use it to power any rig to the crusher, let alone something I would drive every day. I bet with the extra weight that it will add to your rig, the slight (and I mean VERY SLIGHT) power increase will be offset, leaving you with a rig that is just as slow, but even more noisy than when you started.
Go Mopar if you wanna swap! Why? Thats who made the entire rig. If you love it, think about it, its a MOPAR, Keep it a MOPAR!
Can you tell I hate that stupid gay blue bow tie?
After working in too many shops on too many pieces of crap, my brand loyalty is nil. Just take the best items from each manufacturer and put it together in what ever body/frame you want. They all made junk at one point. The 6.5 is one GMs dull moments. The LSx motors, are one of the best things they ever made, though. Take the best from each, and you will have a reliable, powerful jeep. Even if some parts have the blue oval or the bowtie. 10 years ago, there was no way you could ever convince me to put a ford anything into anything I owned. Not anymore, now I have a different view. If it works well, I could care less what name is on it. The ford 8.8 is easily one of the best things to put into a jeep short of going to 1 tons.
I've replaced 3 heads, oil pump, vacuum pump, waste gate solenoid, resleeved the block, and new pistons in my 6.5. I didn't replace the crankshaft after it broke. Now I'm in the process of putting a 383 in my truck where the 6.5 used to be. My YJ is getting a 4.3. If you install a 6.5, hopefully you'll have better luck than me.
