Couple YJ NooB Questions

Would like to get a leaf-spring Jeep. Two questions:

Were there factory built YJ'S with 4.0 liter fuel injected engines?

Is there a GOOD resource for putting CJ front bodywork on a YJ?

Thanks for your thoughts.

Couple YJ NooB Questions

Yes, I got one lol. I believe 92 was the year but maybe 91 for fuel injection and there was both 2.5 and 4.0 versions...I can’t help with the cj mods but I know others have done it.


1992, 4.0,5 spd, BDS 4.5 heavy duty lift, jb conversions ss sye, 8.8 with ARB, Aussie front, tj shafts, dual dia.brake booster, 33” bfg a/t

Yes and 91-95 4.0's were the best 4.0's ever made. in 1997 jeep started lightening everything on the 4.0 (like 70 pounds) and made it less durable. They lightened the pistons and shortened the skirt causing skirts to break and start knocking. And they had problems with the heads cracking and they even lightened the block so much they had to use a girdle on the main caps because the casting was so thin it wanted to twist the block.

The 91-95 blocks were also lightened compared to the earlier Renix blocks. The renix blocks have really thick walls and could be bored over a crazy amount without effecting durability the only problem was Renix injection kinda sucked.

And don't put a CJ front end on a YJ it just looks stupid if you want a CJ buy a CJ. It's like sticking a GT-R badge on a Altima your not fooling anyone and no one thinks its cool.

91-95 yj's were available with 4.0's with obd compliant multiport fuel injection.... absolutely nothing wrong with them.... my 95 has over 260,000 miles on it and I have absolutely raped it for the last 100,000....

Cj front clips were a fad for a while before yj's came to be considered classics.... if it's your jeep you can do anything you want but you'll lower the value of the jeep and catch a lot of flack for it.

Thanks guys. I would plan for an engine rebuilt or swap along the way. For me, it has to be fuel injected. I'd just like to keep the chassis/wiring/accessories/engine all in the 'compatible' model range. Don't really want to put a TJ engine in a CJ, too much hassle for my taste.

The CJ bodywork, I saw one on YouTube, and I think it looked great. I know it's not pure, but neither am I ;-)

If I wanted a FI Wrangler, I'd try to find a 1994-1995 because they have an external slave cylinder and the '95 should have a galvanized tub.
Of course there are other more important things to consider, like miles, overall condition, rust and price.

Once you own it, it's yours and you can do what you want with it. I prefer the looks of a CJ, but wouldn't consider doing anything to my YJ to change it.

Good Luck, L.M.

OK, thanks. I will start looking for a late model YJ, '91-'95. Of course, price and condition will be the biggest factors. Hope I can find one fairly close to stock, without a lot of "lift" stuff installed.

I saved this post. sorry I couldn't get the pictures in. I've been saving my lunch money, and keeping an eye out for a CJ and a YJ grill. I really like the way it looks, and that's what really matters. I don't give a rat's a$$ what anybody else thinks or says.

KY: Yj grill with round headlights

Yj grill with round headlights
Up for grabs is a YJ grill with round headlights.
I posted these pics in the builders corner part of this forum when my buddy and I did this to his YJ. We had several requests for these and made a few extra. I don't know if we will make more once these are gone.
A cj grill and a yj grill were merged together for the outcome you see iin the pics below. The grill wll be ready to bolt in with no fab work left for you to do except add your parts and paint. The red one shown is just for reference.
This grill outright is $725.00.
If you send me one of the two grils to replace one that I used it is $625.00
If you send me both grills this one is $525.00
Prices are plus shipping.
I am set up to take paypal under my ebay screen name (Lavern23) and have positive feedback on ebay. Please check me out.
Well I sold the ones I had converted and just made one for "cjays". It should ship out in the morning. We took 2 grills he sent me and then painted it to match the paint code from his jeep.
I would be happy to do them for those who are interested.

[email protected] is my email and 502-552-6335 is my cell for those who have questions.

thanks,
Chad

The motor issue has been covered so I will talk about the CJ7 conversion. I did this to my jeep the week I got it. The PO had cut up the body so bad I had to order new front end sheet metal anyway and since I like the round headlights I went with the CJ stuff.

You can do all of this with stock parts. You don't need to custom fab anything. But, you will have to do some trimming on the inside of the CJ parts to make them fit. I had to trim the inner fender of both front fenders to get them to clear the frame and shock towers. Basically cut about 3" or so off the inner fender portion. I also had to cut a notch in the bottom of the core support to let it clear the power steering lines. If you have manual steering this won't be an issue. It was stated that they had to cut and lower the front core support on the frame. I didn't have to, I actually had to take out the factory bushing and installed a half inch piece of rubber and it fit fine and the fenders and hood are level.

You can reuse your hood latch on the new core support but you will lose the prop rod. I also had to shorten the support rods from the firewall about an inch and half. The five bolts for the fender to firewall all bolted right up. I did have to drill new holes for the radiator overflow and the horn and washer fluid bottle. You can modify a couple of brackets to use your existing radiator but since I needed a new one I just ordered the one for a CJ. I did do away with the fan shroud and it has never been an issue but you can trim it also to make it work if you need it.

The CJ fenders and core support are about the same price as the YJ's on amazon and it was free shipping. The big issue for me was the hood. I found them at a good price but the shipping was almost as much as the hood so I sourced out one locally for a hundred bucks. I suggest mounting the hood and lining up the core support and then install the fenders to fit. I have a post up on here when I did it if you search my name. All told it took me about an hour and half to take the old stuff off and a couple of hours to put it back together and line everything up. Good luck on your Jeep, let me know if you have any other questions.

Edit: Added a picture of it right after the sheet metal was put on and before the numerous other mods.. All told the sheet metal and all the CJ parts were about $500.00. I added some other stuff but that was for the fenders, hood, lights etc.. If you find someone parting one out you may be able to do it cheaper.

Just looking at the picture has raised a question - is it the camera angle, or is there a toe-in adjustment issue with the front wheels?

Oh yeah, the toe in was way off due to the long shackle lift that was on the jeep when I got it. It has since been corrected with a new Zone 4" lift and I am in the process of upgrading to 1 ton steering and all new ball joints, wheel hubs and axle u joints.

@93YJfan :

Good looking Jeep.

Is the "core support" the front grill, or something else?

Thanks.

Yep, the grill panel on a CJ and YJ & TJ Wranglers is what is typically a "core support" on most cars. The terminology comes from supporting the radiator core. The terms are interchangeable.
"Core Support" is most commonly used in the autobody shop for this particular part.
When describing it on this forum, I try to call it a grill panel, because I think that's an easier recognizable term.

An obscure reference that I hadn't heard until I came West is "radiator saddle". I don't think that saddle would apply in the case of CJs and Wranglers.

Good Luck, L.M.

Really nice work, but I like a YJ better, the late wide track CJs just look like an Old Dog in the Face! Really nice Work, Nothing Down on You, Just CJ's. Sorry!
