xj_dummy Posted June 30, 2009 Posted June 30, 2009 On the "2.5L" on my 86 mj, can I use wrangler performance parts on my MJ?
Geonovast Posted June 30, 2009 Posted June 30, 2009 It might bolt in... but TB spacers are pretty much useless unless you have a plethora of other performance parts, and even then I couldn't justify the cost.
dunl Posted July 1, 2009 Posted July 1, 2009 Very minimal improvements compared to other mods....like and engine swap. :D
philbert001 Posted July 1, 2009 Posted July 1, 2009 The only way a TB spacer is useful, is on a TBI, or carbed motor.
Automan2164 Posted July 1, 2009 Posted July 1, 2009 The only way a TB spacer is useful, is on a TBI, or carbed motor. I am going to agree here. The only thing a TB spacer does is add to the volume of fuel/air mix, and if you are running MPI, it won't work as it would stirring up the air/fuel coming in, and adding a couple of cubic inches of available volume.

BLHTAZ Posted July 1, 2009 Posted July 1, 2009 The only way a TB spacer is useful, is on a TBI, or carbed motor. He has a TBI motor. Still a waste of money IMO. For the money spent, there are no significant gains in MPG or HP. I have tried them on 3 different engines in my years and have been disappointed in all.

I have tried them on 3 different engines in my years and have been disappointed in all. I have noticed a "small" seat of the pants improvement, but nothing life changing. For the price, if you have a TBI setup, just want to eek out some more minimal ponies, and add some anodized colors under the hood, go for it. They are only about $100. Rob L.
