I have a 95 yj with 2.5 L engine with the ax5 trans. and a 231j tc.
it has a 3 1/2 suspension lift running 33 inch tires.
i recently got a 304 engine with less than 14k miles and I was wanting to install this engine in my yj.
have any of you done this conversion? is there an adapter for the 304 to the ax5?
any info will be greatly appreciated.
Where do you live?
If you live in an emisions state, you will never be able to drive it legally, better to look for a 318 or 360 Dodge motor, 5.7L or 5.3L GM motor, or ask some of th eodd folks around here that drop Ford engines in their Jeeps....
The emissions rule of thumb for engine swaps is: Your Jeeps model year or newer engine/induction system.
You WILL want to upgrade your transmission, the AX5 is known to come apart behind the anemic power of the 2.5L Upgrade to a AX-15 or NV3550 for V8 power.
After searching all day for a ax15 with no luck I am wondering if i would be better to leave the T15 trans in?
If I do what are my options for the transfer case??
I have the one that is on the 73 model but I am not sure what that will cause .for me on the shafts?
I guess my question is if I put the original 1973 engine (304),tranny (t15 3 speed),and transfer case(dana 20 I think) will it fit under the 95 yj?
I wouldn't unless the motor is 100 percent stock. Although the ax15 is light years beyond the ax5 its still not half as strong as other options out there, and the 231 case....nah chains are for bicycles. He could use a T18, T19, NP435 mated to a 205 and have a bulletproof setup for cheap.
thanks for the good info.I think I am going to look at the ax15 route.
I have got to get this project on the road!! Bow season opens in october...
I was hoping I could do this upgrade with out killin the old wallet... but I cant use all the drive train in the 73 in the 95. unless there is a transfer case that will mount to the T15 that I dont know about. If that is the case then maybe I could use the 304 and t-15..
As Ibuildem said, I would look into a T18, use the Dana 20 (gear driven xfer case) or pick up a Dana 300 and go with that. I had a 1972 CJ5 with the 304, T15 (which is the strongest tranny that AMC built for the CJ to be put behind a V8), D20. The only problem with the Dana 20 was a high gearing ratio for offroad. The only advantage to it is that the V8 would push through just about anything just idling but not great for crawling slow. If you can find a later model CJ7 front axle (Dana 30) with the same drop as the 20 or 300 TC's output, then I would go that route...as well as a rear axle upgrade.
Got a ax 15 to put behind 304
Pulled the 4banger an ax5 out of the 95yj
Now trying to figure motor mount issue
For 304 in yj.....
Motor appears to be sitting to low..
Any ideas??? Does the AA mounts fix this?
Any info GREATLY appreciated!
You could make your own, just while doing my swap (sbc) I bought mounts. Figured spending money on a piece designed by someone smarter than me and that has already been used on jeeps like mine I knew it was going to work.
The mounts from both companies work with any AMC 304 to 401 motors regardless of what it comes out of,( Jeep, Car, or truck) the motors are all the same. The mount will bolt directly to the block itself.
