I am not sure what the pros and cons of these mods are. i just got in to jeeps after years of ol full size trucks with leaf springs
1. intake from 99 inline 6 motor
2. ford 8.8 axle swap
3. 3 link over 4 link in the front
4. 5.0 injectors over stock
and what makes the 30 such a trud

The Dana 30 isn't all that bad. You can easily run 35s if you gusset/truss it. And beef it up a little. It's the turdyfive that likes to self -destruct.

As far as the 8.8 swap, what rear axle do you currently have? What kind of tires do you use or plan to use?

REALTREEXJ

right now i dont have one i am lookin at a few xjs i just want some input on sum of these mods
and for tires i want to run 33/12.50 super swamper tsl with bead locks

Find one with an 8.25 rear, no rust in the floors, runs good and you'll be ok. Buy from older ppl. Get'em fresh!

8.8 has stronger shafts and housing. some come with disc brakes factory. They'll have like 4.10 or 3.73 (?) gears stock but if you're gonna run an 8.8, chances are 4.10 isn't deep enough for the tire you're runnin. They have way more aftermarket support also. Only cons are a tad less ground clearance at the pumpkin and they and a little more narrow. I can't even notice it with mine. If you can cut and weld, definitely worth the swap imo. I love mine.

You've probably heard the d30 being a turd on them fullsize forums. It's just not enough axle for the tires and motors that most of those full size guys throw at them. They hold up fairly well on these lil jeeps though. I run a locked d30 with 4.56's on 33s and it holds it own. 35s is all i would throw at one though

not to seem like that guy but that was kinda a ******* move man. you didnt really help explain anything. and thank you every one else that has help explain it to me

helmut

Huh? I dont get it. Those are really good answers he gave you. Straight to the point. Best info in short form that you will ever get.

taythegibs

I gave you the exact answers you asked for, you didnt seem to know too much about the different mods so i gave basic answers. No reason to be cussing here

better flow, and if you have an earlier year xj, it also gives you a much better belt tensioner system. no real cons

strong axle, most are 31 spline with disc brakes, huge aftermarket, superior pinion flange compared to the standard yoke design. most are 373 or 410 with factory LSD, cheap and easy to fine.

cons
a little more narrow, cutting and welding required

you mean a 3 link over the factory 4 link? need more details with this before i can answer.

but over all, 3 link provides bind free flex.

more holes, more flow, better atomization

tiny ring and pinion, small axle shafts....but most can run 35's open without to many problems.

99+ intake manifold. No real gain unless you open up you throttle body and exhaust then you'll see some really nice gains. Here's the dyno numbers with other mods.

8.8 requires some fab work and in most cases the 8.25 will get you by just fine and is a direct bolt in. Try for the 97+ with 29 splines and a lsd unless you plan on locking.

5.0 injectors I don'y personally know much about but I run the 703's and love them.

I was thinking about doing the 99 intake.....

With dyno numbers like that it's a no-brainer(given they are true). Before I had 35's my Jeep was quickkkk on stock tires.
