Simply stated. Recently bought my '90 YJ with 86k mi. Want to get rid of my '05 SRT-10 and my '99 Firebird and concentrate on one all-around monster. i.e. bestial Diesel Jeep!
I'm planning to rip up the YJ (which runs perfectly fine) and part it out, but keep the frame to work from for this build.
Unfortunately that's about as far as I get. I really want this to be a project that I do, and I've got some tech-savy friends that can help me. But I need to know where to start dumping my money in order to get this build going.
I figure the bottom up is the best way to go; especially considering I don't have a great garage to work out of.
But I would like to know a little about some diesel engines you'd suggest as well as where I could get the conversion kits (or what I have to cut/weld/mod). I also don't know how the weight will translate into required axle support, or any of that as a matter of fact.
So let's just assume I'm a super dummy and would like some advice despite my staggering incompetance!
Thanks in advance for all your help/critisim/etc.
Cummins 4bt, google 4bt into a YJ and you will find lots of writeups. Thats the next engine going in my YJ.
1992 YJ, 4.0, auto, HP D30 w/TJ chromolys, 8.8 LSD, 4.10s, AA SYE, Tom Woods shaft, 5" lift, 35" MTZ's, 12k winch, Mark VIII fan, 136 amp alternator, TJ flares, custom snorkel and rock rails, no track bars or sway bar
I know I can't expect the same, but everything about a Jeep is so much more appealing to me. The turn radius alone is nothing to scoff at.
Park a four door SRT-10 50 times and tell me you don't miss your Jeep!
But I'm just looking for a daily driver with a little pick-me-up and the ability to do pretty much anything. The MPGs will also be a big plus, as my Viper gets 10.7mpg based on my fuel monitor.
We'll see how things go. I may keep the SRT-10. But between the Jeep (once diesel), the truck, and my sport bike, I'm pretty sure there won't be much I can't do.
Thank you both for the input and help! I feel like I've learned a shoot ton already!
Would it be awful to ask what would make the 3.3 a better candidate than the 4bt?
Is it only the weight?
I suppose I should look it up, but I wonder what the stock power vs reasonably increased power gain is different in the 3.3 vs the 4.0...
Or is there some other efficiency issue I'm too new/inexperienced/toolish to realize?
As I've said I plan to use the time I have to make this project a success. Which means figuring out exactly what I want the end result to be before I start buying.
Dang, you saw my stupid post before I could edit it.
Sounds like a great deal as far as mpgs at least.
I imagine it will then still have a comprable effect on the drivetrain & axle?
If you're tired of answering questions I'm sure I could use a 4bt build from the website only with a 3.3t in exchange as far as engine right? Oh, and are the engines comprably sized so as to fit the same chevy engine mount kit?
Thank you again!
