Hey austin lets hang out and you can make a video and work on my jeep. you can be like heres how to install headers exaust cold air intake and new injectors. out jeeping lets get it.
Just fyi to to the XJ'ers, 62mm TB's come literally stock for a grand cherokee, YJ and JK and cheap as dirt off of Ebay. It was in the later half of the 4.0 that it finally got upgraded.
Does the upgrade require anything else to be changed? What does the upgrade improve and or change? Thank you. I appreciate your videos, they have helped me in numerous repairs, saving me money.
I have a vacuum leak , won’t pass smog in CA. I smoked the motor and found smoke coming from the Butterfly shaft of the TB . My Question is.. should the TB have “No “ smoke coming from anywhere? …
@@OutJeeping Have had any luck with the after market 62mm BBK ? RockAuto sent me a remanufactured one that the smoke test proved to be worse the my original TB.
What's the point I got a stock Throttle body with a Spacer and cold air intake . Aint that the same results in the end gonna still take same air to fule ratio unless you program the Pcm otherwise 🤔
It will be the same air/fuel ratio but with a bored out throttle body, it will increases your throttle response because more air can pass through faster with a larger hole. As for a throttle spacer they don't really do anything to increase performance unfortunately.
If the rest of the engine internals are stock it doesn't need a retune. This forum explains some of the benefits. www.cherokeeforum.com/f2/4-hole-vs-6-hole-vs-12-hole-injectors-best-245564/
You're engine burns the vapor from the holes so with one hole its more a "stream" of fuel while the 4 hole injections distribute the fuel more efficiently
Would this make a difference in throttle response for basically an all stock grand cherokee. Stock size wheels 2001. Sorry if this seems like a silly question. I just notice you have replied that this throttle response made yours "feel more like stock" since the bigger tires made it sluggish. Any feedback is appreciated. Thank you
OutJeeping thank for you'r reply sorry it took me a while to get back to you i was working on a friend's car the tps sounds like time to replace it i just think checking seancers when you have something apart it's good time to know what is what and easier in stead of finding out later for you'r jeep less trouble on the street and off road plus for it to run good and get the best m.p.g. have a very good night C😎😎L
Does DW Designz still make these? Does he have a website or better place to purchase now? I never got a response on Facebook and KSuspension doesn't carry it anymore.
Intake is 63mm for direct bore match. Just did mine with 4-port injectors. Reset the PCM afterwards by ground positive cable on negative 30 secs...ignition on but not started, headlights on then off then ignition off. Viola~
Throttle body spacers don't have any proof of performance, and using a hole saw is not as accurate as Machining a surface and having it fit perfectly with a new butterfly valve
@@OutJeeping right, but the space was for getting the hole perfectly spaced, and centered. But you neither used a hole saw or had it machined and just plopped a 62mm tb onto a factory hole in the intake. The intake hole is 55mm
Aside from being a dog, the throttle response is as 'right now' as a cable driven throttle could be IMO...drive a 6cycl Trailhawk sometime. 2-sec delay from input to reaction! Almost dangerous. Throttle body upgrades (in my past) were done in conjunction with porting and exhaust upgrades. And ignition. Just the TB might not be a value added item by itself.
A lot more responsive, my jeep is very sluggish with stock gears and 33s and this makes it feel more like stock. I will make another video on 12 hole injectors soon so then we can see the difference even more.
Ohhh. Kaaaaay...........I searched for a vid on this subject for the explicit purpose of seeing how to disconnect the throttle body cables and what do I see? The swift disconnect with the cables hidden by gloves........no close up of what you were doing with that screw driver or how to avoid damage to the cable end fittings. Move on........nothing to learn here.
Let me guess you also disliked this video because you got all flustered? The amount of disrespect from people like you who get pissed at a free video on the internet is unreal. Getting the throttle cables off is easy as shown! Pull the opposite end of the cable and it pops out, for cruise and trans cable.

should be titled "how to change a throttle body" Bro we can all change throttle bodies. that's four bolts, a few cables, and a plug or two. Thought you were going to be SHOWING us how to bore out a throttle body to 62 mm.
Would have been nice to have a review of results and perhaps comparison of revving between the two Tbodies.

If you did a aftermarket intake, and a header, that bigger TB would make a noticable difference in power.
just whit a trotter body specer n 62 mm trotter body from bbk n i cut the post cat i can feel the difference
It's about 4 or 5 horsepower. I bored mine out on a Bridgeport mill and made a new throttle plate on a lathe.
The throttle plate is actually oval a bit. The plate sits in there on an angle, so I mounted it a mandrel at 5° when I machined it.
IＩflip the clips off with my fingers to remove the air filter cover
people with lady fingers need screw drivers
Dude holy shit! You got balls of steel!
@@OutJeeping he doesn’t know that the clips are thermal sensored and react like temperature stat coil . Shhhh 🤔
Thanks, learned much, thank you

The upgrade improves throttle response mostly. Nothing else needs to be changed.
awsome vid
I would like to hear your opinion on it, good install tho
Defiantly more responsive and in easy upgrade for the 4.0
What is the stock Prada body for a 4.0 did then got bored out to the 60 mmm, and what was the end result, and final cost plus or minus the $50 core
That’s awesome Austin
Is there another place to buy that TB? how can I look for it?
The link for the part in the description is dead
What were the results? Power increase? How much?
I never took it on the dyno. But from what i hear it doesn't gain any power really just throttle response
Better throttle response is well worth the money and effort to put it in
I was surprised that you didn’t have to open up the intake manifold hole to accommodate the increased opening
The intake hole is already bigger than the throttle body.
Didn’t know some CZcams’s show them grinding the hole. Did it make any difference?
If i have a rough country throttle body spacer can i still use it with thisb
Should be able to. A spacer isn't doing anything though.
Great video! Do you think they make them for a 98 Grand Cherokee 5.2l V8?
Offroad Maniac I think they only make them for the 4.0 but I'm sure there are other companies out there that make it for the v8.
I have a vacuum leak , won’t pass smog in CA. I smoked the motor and found smoke coming from the Butterfly shaft of the TB . My Question is.. should the TB have “No “ smoke coming from anywhere? …
Correct, those shafts could wear out and cause vacuum leaks and possible high idle issues. I would recommend replacing it.
@@OutJeeping
Have had any luck with the after market 62mm BBK ?
RockAuto sent me a remanufactured one that the smoke test proved to be worse the my original TB.
I haven't ran any aftermarket throttle body other than the original bored out.

It will be the same air/fuel ratio but with a bored out throttle body, it will increases your throttle response because more air can pass through faster with a larger hole. As for a throttle spacer they don't really do anything to increase performance unfortunately.
I am looking into the four hole injectors. I heard the CPU has to be retuned? Could you explain benefits of a more holes please.

You're engine burns the vapor from the holes so with one hole its more a "stream" of fuel while the 4 hole injections distribute the fuel more efficiently
It also allows for better fuel burning and fuel economy. Not much but slightly from what I've seen

I just notice you have replied that this throttle response made yours "feel more like stock" since the bigger tires made it sluggish. Any feedback is appreciated. Thank you
Yup it would make the engine more responsive to any application
What would happen if I use the 60mm throttle body?
More throttle response than stock.
what are the pros ana cons of this, doe this increase HP or just a repair
Pros - better throttle response and gives a little more pep while accelerating. Cons - no real hp gain but a better driving experience.
good up grade some thing I would have done use a ohms letter to check the sencers to make sure there in speck C😎😎L
Cole Webb Yeah I should have done that because the jeep is actually throwing a code for low voltage from the tps.
OutJeeping thank for you'r reply sorry it took me a while to get back to you i was working on a friend's car the tps sounds like time to replace it i just think checking seancers when you have something apart it's good time to know what is what and easier in stead of finding out later for you'r jeep less trouble on the street and off road plus for it to run good and get the best m.p.g. have a very good night C😎😎L
Cole Web
Benefits on a bored out 62mm TB?
Mostly for throttle respose
What made you choose the 62mm vs other larger diameter throttle bodies?
Intake manifold is 62mm
If i have a bigger throttle body will i need to run a different tps
All factory sensors should work with no hiccups, that's how I'm running mine.
Will this fit on an 88 2.5L YJ?? Cause I need a bigger throttle body
If you go on DW Designs Facebook page they have multiple different sized throttle bodies for different year Jeeps.
i just installed this but now my gas pedal is hard, any idea why?
I would double check your cable routing and make sure nothing is getting bound or snagged up on anything.
Does DW Designz still make these? Does he have a website or better place to purchase now? I never got a response on Facebook and KSuspension doesn't carry it anymore.
I am not sure on that, I will have to look into that because I will be needing one here too for my other Jeep.
I have a 1988 with a Renix. What do I do?
They have their own throttle bodies that can get bored out as well.
Good upgrade man 👍👍👍
Your mom was a good upgrade as well
If I do this upgrade to my xj would I have to tune it ?
No
Did you bore the intake manifold too? I thought the intake had a smaller hole than 62mm
Nope I believe the manifold had a bigger hole
@@OutJeeping thanks! I hope so, my XJ is from 97 and has the log intake. Bored throttle is on the way!
Intake hole is bigger 10 mm socket for bolts and you can find out yourself in 5 minutes
Intake is 63mm for direct bore match. Just did mine with 4-port injectors. Reset the PCM afterwards by ground positive cable on negative 30 secs...ignition on but not started, headlights on then off then ignition off. Viola~
I've seen guys put the 62mm spacer in, then with a 62mm hole saw, open the intake to exactly 62mm. why you not do that?
Throttle body spacers don't have any proof of performance, and using a hole saw is not as accurate as Machining a surface and having it fit perfectly with a new butterfly valve
@@OutJeeping right, but the space was for getting the hole perfectly spaced, and centered. But you neither used a hole saw or had it machined and just plopped a 62mm tb onto a factory hole in the intake.
The intake hole is 55mm

Do you have a 4 hole injectors?
I have the 12 hole injectors.
@@OutJeeping does it spend too much gas or normal ?
@@omaralblowi6278 Its the same fuel flow as stock but has better atomization.
Not sure this is going to matter if you don’t open up that stock gasket.
Gasket is larger than both throttle body holes, so no trimming necessary.
Will it make gas mileage worse
I haven't noticed a difference in mpg.
OutJeeping okay thats good. I just bought 4 hole injectors and im looking to get a new throttle body too
does it worth or not?
Increases throttle response, not a huge difference though.
How much horsepower did it give you
Nothing noticeable except an increase in throttle response.
Lol.
Wh5
Wouldn't this give you very poor fuel mileage? I get poor enough mileage now in stock form. Thanks
It shouldn't make a difference in that aspect only in throttle response, its not like a forced induction intake.
If you are worried about fuel mileage go buy a fucking battery car you bitches!!🇺🇸😈
Doing this on your seat is funny...
Gotta do what you gotta do in the college parking lot.
@@OutJeeping tailgate
@@mercman2.5 It was full of crap and it was cold out.
does it still start?
Yup, why would it not?
Maybe it's me they look the same size
The new one is straight bored through compared to the stock one which as a lip mid way.
@@OutJeeping did you keep stock injectors or you have 4 point injectors well like the dodge neon kind
@@vee950 I went to 12 hole Bosch injectors, I got a video on installing them.

Depends what the bore size is on the RC spacer. Needs to be at least 62mm for this upgrade to be effective.
