hello , thanks for looking at this. please help. i recently purchased this 95 yj 4cyl 5spd for my younger brother. he's currently in iraq and is coming home soon. he always wanted a yj v8 , lifted , to go with his buddies trailing. what do i need to do to make this project a reality for him. i'll do most of the work myself and what i can't i'll get help. please advise. currently have a h.o. 350 ready to go into truck but what else needs to be done..this is also budgeted too b/c my wife may kill me if i get carried away. thanks again  

I am no expert but i do know there is alot of work involved in such a swap, to start you will need a transmission, probably easiest to get an automatic with overdrive off of an 4wd chevy truck with a 350 in it, your jeep should have a np231, i beleive advance adapters makes kits to adapt them, thats just the start of your problems, the stock axles will not hold up to V8 power, so you need to be looking for a good set of donor axles.  I suggest becoming good freinds with your local junk yards.  There is much much more, that is just a start for you. Even getting most of the parts through junk yards, this is still a costly procedure.  good luck  

Im thinkin about doin the same thing.  I have a H.O. 305, with tranny and transfercase. I have been told that the stock tranny will not hold up to a V8... and chances are your transfercase wont work either... if i were you... i would tell my little brother that a six cylinder essentially has more power than the eight cylinder. (or just go for broke and drop a cummins in it... that would be fun)

If anyone has any info on putting a vortex 4.3 Liter in a 95 YJ Wrangler... please let me know... i have tranny and transfercase for it.  Any info would be great. Thanks.  

What year 4.3 is that?  I build the electronics for 96 up fuel injected 4.3  

its in a 94 s-10 blazer and it is fuel injuected  

I am in the process of this swap right now. A jeep 6-cyl. would be a way more easy swap. You would really only need to upgrade your trans to the AX15. Everything else would be good i believe. I am 3 months in the process & about 2K-3K into it & I still have 2 more months & another 2K to go. I am buying everything new (exhaust, radiator, etc.) because i've had bad luck in the past with junk-yard parts. I am putting in a 400SBC & TH400 trans. The NP 231 should hold up. I have a ford 8.8 already in & i am going to have the dana 30 until it blows. Take my advice go with a fuel injected 6-cylinder. If you spend 1/3 of the money you would putting in a V8 & stroke out the 4.0l to 4.6l, you will have just as much power as a v8.  

just like he said get the tranny and case the take the inner fenders out set the engine in and start building
