Ok so I just want to add a little more power and better throttle response to my beloved xj and was wondering what to do cheaply. I have upgraded the cat with a high flow magnaflow and I got more power from that. Does a tb spacer help at all? What about a bored out tb to 60mm? There is a vendor that sells them on here. Then I was also thinking about injectors. Is there any injectors I can pick up from a certain vehicle at they jy to give me more power? I have the 4.0 I6 btw. Later down the road I am thinking about getting a strikers and upgraded header but that is outta my price range for now. Anyone have a good link to a strikers kit that won't break the bank? Anymore ideas on how to increase power shout em out! Thanks! Also I already have champion copper plugs and have got new cap, rotor, and wires

 

Put stickers on the rear window of your jeep

 

Remove crush in down pipe. Better injectors. Better cat and muffler bored trottle body. 4.2 stroker.?

 

Ya I forgot the crush. Already upgraded cat and muffler. Injectors from what vehicle? Can I grab them from the jy. Bored tb is on the list. What about tb spacer?

 

Ya I heard u gain some HP when doing that

 

Why do you need more power. More power equals breaking more things. If you are looking for 10 extra hp, its doable, but anything higher then that and you will have to spend some bucks.

Use the jeep for what its ment for, if you want more power buy something else.

 

Ya that's fine just some extra power to push bigger tires down the trail and maybe burn a few ricers on the street

 

+1

 

!! Not looking for much just a couple HP here and there

 

Tb spacer is garbage

 

the bored TB helps, it feels more responsive.
If you have the stock airbox, there is a restrictor in the outlet snorkle, pull that out.

 

Ok ill see if I can find that

 

Change speedo gear!!!!

 

change the gear ratio?

 

Doubt ill need to do that for 31s
