Topic: 4.0 throttle body

[lanulos89]

well i was in the 2nd year auto class at school this morn, and looked around found a old 4.0 engine chillen on the floor, so i talk with the teacher, and he said i could have the 4.0 one as long as i give him my 2.5, well now morow morning i have a new throttle body to put on, hope to see a difference, and the best part is, its free.

nice find....

[Jeffy]

He's going to wonder why his 4.0L is still there, I bet....

my shop teacher wouldn't even notice and or care if i just took the throttle body one day and put my 2.5l one on it the next day.

shop got cut at my highschool, they built a brand new highschool my senior year (5 years ago) and decided not to build a new shop--poor choice

Yup, that is happening all over the place.  I think shop is able to give kids something other then school.  It's actually fun and it's something that you'll take where ever you go.  It was well worth the cost. (free)

I like how schools cut things like shop but don't dare consider making Algebra optional.     At least I might be able to use shop later in life.

nah i goto tech school in the morn, high school pays for it, and i miss half a day of hs being there, this teacher just has piles upon piles of motor laying around, and begining of the year he stripped a grand cherokee, so yea thats where my throttle body came from.  anyways i did the swap this evening and rlly liked the difference.

there making a new high school that will open the year after im a senior... looks like it will have a bigger shop than the one at my high school.. but the new high school is just a big waste of tax dollars.

If they don't build it, they're going to have to start stacking you kids 2 high just to fit in the old school   I don't think you realize how huge the population of 6-12 year olds is in the district, they're building an elementary school every 2 years just to keep up.  (Yes, I voted to raise my property taxes to build it )

I'm glad they're putting a nice shop in the new one.  My son is pursuing the engineering program at the current school and makes a lot of use out of the shop there.


Nice score on the throttle body, I had a friend of mine bore out my stock one on his mill.

Oldjeep,

Since I don't have the skills or friends with the skills to modify my tb I got a 4.0 one on ebay.  Just a couriousity question.  When you had yours milled what did you use for the butterfly valve?  I hope thats the right term for the round plate that is in the middle of the TB.

Mine is just milled so that the diameter of the lower part of the throttle body is the same as the butterfly diameter.

going to get 4.0 tb soon but can't figure out with all the engine mods on mine if it would be benificial to go to a 62mm or that is going to be too much.  i brought my intake system back down a notch and brought my torque back up.  i also ordered a set of 19lb injectors and a afr gauge so the tb should be the next step.  anybody notice how expensive they are getting?  it's hard to find one for less than $50 now.  anyway chime in and let me know what you all think.

What you do to bring your intake "down a notch"?
