- This throttle body comes off a Dodge or Jeep 4.7L V8. Would be a great mod for a stroked 4.0 or a highly modified 4.0

Amazing! By far one of the best how to videos with pure jeeper mod! Was amazed when mentioned neon injectors plus like the in cab air filter
Thank you, I appreciate the positive comments.It makes all the work this video was worth it.
I appreciate genuine good hard working craftsmanship well done
Thank you, I appreciate that. Glad you liked it.😁👍
great attention to detail!! master of fabrication!
Wow, nice to see people still have skills out there. Very cool to watch this project!
Thank you, for the nice comment. I enjoy doing these kind of crazy projects.
Crazy design... looks cool 👍🏻👍🏻
Excelente trabalho de adaptação. Não achando mais os originais, esse é o trabalho a fazer. Parabéns Martin.
Thank you!
Thanks for all your effort.
Great watching your work!
Thank you Shay
Awesome job man, i really appreciate with you taking your time to make this video
Thanks Ruben
Great video Martin! I'm excited to have found your channel here!
Well Martin, looks like this is on my to do list before I start on my stroker build. I have a couple of the newer intake manifolds and power steering brackets in the garage, still need to pull the pumps and swap out pully's. Thinking of picking up the Harbor Freight mini mill for some of the simple machining stuff as I don't have a drill press yet... 2 birds I guess.
Good work by a true craftsman. Did you have a chance to quantify your work and efforts by doing a dump run before and after? That's an awful lot of effort and time. I wonder what sort of gains it brought you.
+2hp.
Great job thank you for sharing
Very detailed presentation...nicely done...thanks
You are very welcome!
Yes sir fine craftsmanship u should put up something on the early 4.0 as there isn't much out there for it and i sure alot of us would love to see what that wonderful mind of yours would come up with hope u see this >rob
nice job done and nice equipment for doing it all.
Thank you!
Someone should Machine up and sell adapters for these.
That was definitely a "Pro Tip" on the use of rags and topping it with grease to catch the shavings. I was wondering how you were going to keep the savings out 👍🏼
Glad you liked it.. Yeah I love this throttle body it would really be great on a bored and stroked 4.5 and large engine.
very well engineered.
Thank you for the video!
Glad it was helpful!
Niiiiiiiiiiiiiiiiice martin you are an real mechanic tech
Thank you :)
Very cool.
Trusted Design Services, LLC sells the adapter $75.00. Google them 2/29/20. On EBay TDS - throttle body.
Great Mod !! That would work with any of the L6 motors .. Thanks ..!!
Hi Martin:
Just found your channel a couple weeks ago and now I watch you every nite. Yours is by far the best channel on repairs on CZcams. I watched ur video on fuel injectors and was thinking about trying ( I have a 96 ZJ 4.0L) the Denso 12 hole injectors. What vehicles can I find these on at the "JUNK YARD" ? Thank You again for the best videos, keep up the good work.
Wow, thanks, I would recommend the Bosch 280156161 12 hole injectors from the Ford eco boost engines found in their compact cars like the Focus but you will need to change the connectors to the EV6 style.
@@martinbuilt Thank You. In a couple wks am going to try the local "U Pick" and see if I can find those Bosch 280156161 12 hole injectors. Here is a tip you might pass on. Am doing the rear diff fluid now, Dana 35 and I soaked the bolts & cover in vinegar for a couple days and the RTV comes right off. Watched your wire tuck engine compartment video last nite. What a job but it really looks great when you finished. Thanks Again
Love your videos man. Keep up the great work!
Question
Can a bad Throttlebody make your Jeep not to stay on. It cracks good but won’t stay on Everything is new on it
Martinbuilt: Always thinking. Question: do you use the Learn mode on the XJ. I just joined by buying a 2001 jeep Cherokee XJ. So I’m learn mode right today. Going to u pull u save tomorrow another item to get a TB off of a WJ..
right on !
Muy bien , mas una cilindrada de 4.6 LTS (282 pcd) como se producian los motores de AMC / VAM en Mexico seguremente alcanzaria hasta los 270 HP y un torque de 330 Lbs / Pie. GRACIAS ¡ por compartir tu video y felicidades .
Hey Martin, I have a thought I want want to pick your brain about. What do you think about matting a Hemi to a 6 speed mustang manual transmission. I been thinking about this for a long time as a project for a xj6 jaguar that I have. Do you have some input on this??
Good work props 👍👍👍
Thanks 👍
Awesome video man
Thank you!
BET YOU DIDN'T KNOW THE GRAND CHEROKEE 4.0 IS 87 YEARS OLD !!ITS PROTOCOL WAS THE NASH AJAX 6 IN 1934!! AND THATS THE REST OF THE STORY!!!
Do you happen to have any info like prints or templates on how you made the spacer??
great video!
What size throttle body should I put on my 03 Grand Cherokee stock 4.0 along with upgraded 12 hole injectors? Should.I upgrade coils/plugs or anything else? I do already have a K&N air filter as well!
I would recommend the stock size to 60mm unless you start to make exhaust upgrades (header, hi-flow cat, cat-back exhaust) you could go up to 68 but, a 62 would work great.
Nice i go to doit in My renix engine i have 99 manifould and head for convert My renix un to a HO
"SO SWEET"!!!
Very nice budy... Sorry i have a question...
- this upgrade spend more gas per gallon?
- how many hp increase
- wy are U do that...
Plan "B" make me lol...
Have a nice Day..
hola! genial. hello, because you make me one and send it to me, to install it in my cheroke, how much does it cost?
So what were your results with this? Impressive fabrication, not sure if you did swap injectors, but were there any improvements?
I could really tell at the top end and at the time I was using the Bosch 703 injectors.
hey man do you fab and sell these upon request, would be a nice addition to my turbo tj stroker
Does any one make a pre manufactured plugin spacer for this application?
You could just get this TB www.painlessperformance.com/webcat/65301
Wich I was so clever I could do that. Nice job
Great video. Maybe i missed it, but why didn't you use the new intake manifold? Aren't they supposed to be better? Thanks.
Yes I will be swamping to the newer intake. But wanted t do it at the same time I install the new header.
Nice mod but it looks like u have the old style intake on your jeep. The one u had on the bench is newer and flows better
Couldn't agree more, I installed the 99 up intake shortly after this video was posted with a brand-new Pacesetter header.
I'm going to be machining the plate to adapt the throttle body soon. Is the bore drilled in the center or the 5x5 plate or is it offset?
Cant remember for sure . I think it is offset. I'll have to look.
martinbuilt was it worth it? Any loss in low end torque? Is it touchy while rock crawling? I have a 4.7 stroker with a cam, horseshoe intake a header and a bored 60mm tb. Just don't want it jumpy while crawling and I want to gain low end torque.
I am have lost a tiny bit bottom end. It's not touchy at all. It was worth to me.
I'm actually in the process of doing this, and I'm guessing you used the 4.7L sensors & harness. You must have spliced the 4.7 harnesses in. I just don't recall you mentioning that. How'd that work out for you? Are they sending equivalent voltages to the ECU?
No, I used the same TPS and IAC, just moved them to the 4.7 throttle body.
@@martinbuilt Yeah, I have a different idle air control on my '93. It makes a 90 degree bend for a male style harness. Another reason I mention it, is because the plunger on the IAC is slightly smaller on the older model. The TPS I have got to fit, but am having an IAC issue. I'll let you know how it goes when completed.
Wonder if you could 3d print the adaptor......
Wide range of material choices
I don't see way not, ABS have a very high melting point.
Why run a 68mm throttle body on a pre 99 style intake manifold? The manifold is the bigger bottle neck and swapping in a 99+ manifold is a much simpler modification.
I have the 99 and newer manifold just haven't installed yet as I'm also will be installing a new header and wanted to do it all at the same time.
Thaddius Smith I thought that myth was busted by jp magazine.
Why can I find so much after market parts and stuff for my beloved jeep but when it comes to throttle bodies it is slim pickins? I would buy this so hard, I am tempted to make it too but I don't have nearly the same amount of tools and would be doing it on my apartment patio which is far from ideal in so many ways... I really want a 68mm too the only one people seem to offer is 62mm which is nothing more than a ported factory throttle body, which I have doubts about there being much if any air improvement, since you cant port the valve portion... ugh.

So now that you've had this mod in your jeep for a while, have you noticed a jump in horsepower?
Arthur,
I wouldn't say there was a jump in HP. I think it is something you would have to put on a dyno before and after to see the difference. I think this mod is best suited for a highly modified 4.0 or best yet a stroker 4.5 and larger. I haven't seen any ill affix from this mod and this throttle body is here to say.
Nice video you should make them and sale I would be interested in something like this for my Jeep damn instead of taking Woodshop I should have taken machinists elective class in high school ha ha ha
If I had the right tooling to mass produce I definitely would consider it.
LS1 Throttle Body bolts on 4.0L
abdulrhman saleh
if you're asking if you can put an LS1 throttle body on the 4.0 I think it's possible. the LS1 is very large at 75 millimeters. the problem would be that you're going to run into the throttle body bolt holes on the intake manifold. you would probably have to weld an aluminum adapter plate directly to the intake manifold
martinbuilt no I'm not asking، i have 2000 4.0l Cherokee with ls1 throttle body it's bolt on if you want to see shot my email abdulrhman saleh
martinbuilt
Nice engineering on this project. Thinking outside the box is always interesting.
abdulrhman saleh send be a pic
Hey man can you email.me a pic of the ls1 throttle body on the 4.0 ?
Is your 4.0 stroked? If so can you share the details? i just ordered ATKs 4.7 stage 1 stroker block.
+RagingPirateNo it's a 4.0
+martinbuilt I think I'm going with a 62mm throttle body bc it's alot easier and I'm not as talented as you and do not have all the machining stuff. Although, in the future I may go with this setup. Awesome video. Thanks for the quick reply! Jeep on brother.
What happened to the beard? Nice upgrade, you make it look easy
Thanks Rick, I appreciate the kind words.
why is the drill press running backwards
It does look that way but it's not some kind of optical illusion with the video
Did the 68 mm make much difference?
Yeah I felt it did especially on Mid to Upper range.
How much torque and horsepower have you gained from this? Very nice work sir! I would screw this up and it would be a total disaster!!! I bet it took some hours thinking of how to mesh everything together..
Almost Zen I don't have any Dyno tests or anything like that. I definitely noticed a upper end Improvement. Yes engineering the whole thing is what takes the most time.
martinbuilt dyno tests are rather expensive.. I was just curious that's all.. I have a few issues with my 4.0l such as a few minor oil leaks and when accelerating my ac/heat will transition to the floor or defrost for a few seconds and then return back to the front vents.. The very first problem that I considered was a vacuum leak but I can't find it.. Any suggestions?? Thanks for the reply..
Almost Zen yeah that's what I thought right away too when I read it was a vacuum leak. Yes Dyno tests are kind of expensive. Never had one done before.
Almost Zen the vacuum ball/pill mounted behind passenger side front bumper must have a leak/is disconnected.
why dont you have a air fuel meter?
No special reason I don't really need one.. Just to make sure we're on the same page you are talking about a air fuel ratio gauge?
why is this not a good idea for a stock 4.0?
+Scooby Doo
It would be like installing a hi lift camshaft on a stock engine without making any other changes. If your going to install a large throttle body then you need to address other parts of the engine as well, like cold air intake, free flow cat, free flow exhaust, port matching, bigger valves, etc.
how much power will this add to a 4.0?
Rafael Farias
I'm not recommending this for a 4.0 but this would be a great upgrade for a 4.5 and larger stroker engine.
alright thanks, awsome video
So have you noticed any differences?
A little to early to tell yet. I have run one tank of gas threw it so far. Got 15.2 mpg. Is down by about 3 or 4ths. But I was having some fun with it, so that could be that. It does sound nice.
Nice work but for all of that I'll just pay the $350/400 an buy 68mm jeep spec throttle body
Yeah when I made this video there was no such thing as a aftermarket 68mm throttle body....Hmm...wonder where they got the idea...lol
@@martinbuilt that there is true It wasn't available and even now only a couple companies do it every ones just making 62mm for the 4.0 so sad
do u sell them ? for jeep ? 4.0
No, I'm not tooled for mass production. Thanks for asking.
martinbuilt would u make me one if i pay u ?
@@elvynortiz3456 well I wish I had the time I'm always trying to put out new videos and it takes a lot of my time. I was looking at painless makes a 68 mm throttle body. For $489 the only thing I don't like about it is the outlet side of it looks like it's 62 mm. I wonder if it be possible to take their throttle body and bore out the outlet side of the throttle body to 68 to make it a true 68 millimeter throttle body and then do like I did and bore the intake manifold to match.
thank you for the info very much I see what can I try
Hey Martin how have been?
It's been going very well. The new job has been great.
How have you been?
martinbuilt
Ive been well thanks for asking , new yob?
Ive been busy on my projects here in the garage ,got the welding table mostly fabbed up , I started tearing down the motorcycle engine , I m gonna film it and start posting some youtube videos
Definitely not worth it
5 years ago I too swapped the injectors to the 5703 Neon injectors on my ZJ. Question: After doing this, did you have to upgrade to something else or no? I saw in another comment you mentioned it wouldn't have full potential without other supporting modification, however, that is exactly what I'm doing on our kids XJ.
Since then I have upgraded to the 99 intake manifold, currently running the 280156161 Bosch injectors 12 hole, also have a Pacesetter header and Harland sharp roller rockers. I also have the aluminum Edelbrock cylinder head just haven't got around to installing it
Great video Martin! I'm excited to have found your channel here!
