Jeep XJ 4.6 Stroker Build
Вставка
- Опубліковано 21 лют 2020
- After 280k miles and wanting more power to make it up steep grades when loaded with camping gear and armor, it was time to build a 4.6 Stroker. I called Russ Potenger @ BishopBuehl Racing for a custom tailored kit including custom pistons, skat 4.2 crank, skat rods, ported/polished head, ported intake manifold, comp cam, LS valves, and all bearings, seals, gaskets, rocker arms, pushrods, etc. It would be my first time attempting an engine build so I enlisted the help of my friend Mark to guide me along.
If you've built a Jeep Stroker, how did it go? Let me know if you had any surprises like I did with faulty wiring.

The ending brought tears to my eyes
Nice Cherokee. Wonder why everyone jacks up the car and THEN thinks, "hmmm, maybe I should rebuild the engine....." Great hobby, tinkering with a Cherokee. I drove a 98 Cherokee, 2 Dr, Rear wheel drive, stick shift for nearly 10 years. Just needs oil and tires to keep going and going. Cheers!
Great Job on the rebuild the Jeep sounds great.
Really like the editing in the video very professional. Love to watching jeep xj vids
Thank you Angelo! I appreciate the feedback 😊
Great editing and video quality. Fun to watch!
Thanks Rader! I appreciate the feedback :)
Great looking (and sounding) Jeep. Thumbs up NAXJA members!
Thanks @EricsXJ ! I am a big fan of your XJ as well and hopefully one day I can join one of the Sierra Chapter runs and wheel with you guys. :)
Absolutely awesome video
Thank you!!
Amazing job... Nice Jeep xj.
Thank you! 👍
Great video! I've got a ton of armature XJ repair videos!
My favorite Inline 6 over any other even The Ford
Do you think you should upgrade the rest of the drivetrain? Tranny, axles, etc? How bout the brake system?
Great video. Whch flowmaster did you use?
I eventually want to do a 4.6 striker for an 04 grand Cherokee with 4x4. I have a 2wd 4.0 and I love it, it’s responsibly fast for my first car
Right on! I think you will really enjoy the extra power and torque when you do :)
Sporting a NAXJA shirt. :)
how's this thing holding up and what's the fuel economy like
Nice build. Have been really looking into LS verse 4.6 for over 18 months and right now leaning towards the 4.6. It’s hard when both of our Jeeps are low miles and run perfect. We are not looking for anything wild sense trail reliability is a must. Looks like you made a wise move on parts selection also. Good luck man.
Thank you! It was a tough decision, but unfortunately trying to get an LS to pass CA emissions is next to near impossible. I also wanted to keep it looking factory with a little more power. I have been crazy busy the last 6 months, but I am putting together a follow-up video with some tips and thoughts after driving it all summer in the heat.
Whenever you guys need to pass smog reach out I’m located in bell ca near Los Ángeles there a lot of spots over here no need to bring car in to the shops
Bwahaha, you didn't catch me cursing you. Nice engine hoist!
I kept it PG 😂
For everyone wondering about the fuel economy and power, fuel economy is much worse than when they are stock and you don’t really feel much more power. I recommend just Ls swapping if you truly want more power and better fuel economy because it’s almost a waste of money and time doing a 4.6 stroker, just speaking from experience.
My fuel economy is the same as it was with the 4.0. Then again, this build used custom parts that were engineered to make it reliable and provide alot more torque than before. An LS swap would have been awesome, but in California it's very difficult and expensive to pass smog. In other states it might be alot easier and less expensive.
I dont think so, you can get a 350HP 4.6l from Newcomer, so almost twice the Power, obviously fuel economy is worse, its a bigger engine. If you realy think its not worth the money, do so, but i rather believe a Engine-expert specialised in building stroker 4.0's...
Great video.
Got my RP kit waiting to be installed for my TJ. Russ being a great guy NAXJA the best redurce with lits of nice people there.
A followup video?
Awesome! Cant wait to see the results, let me know how it goes!
Dose it pass inspection. Did the check engine light ever come on?
Finding an untouched XJ wiring harness is a miracle.
So true, although I will say the o2 sensors were cut off, but overall was in good shape.
Did you have to have the It tuned after the swap?
What's your mpg? And or tire size and gears? My jeep has 217K and time for more power.... look into advancing the time with a crank sensor mod that's the biggest power gain done to my xj.
Hi Douglas! I'm averaging 14 mpg with 33s and 4.88 gears. My XJ is a bit heavy though, at around 5k lbs with all my gear, armor, etc. If I keep my highway speed below 70mph I can do better at around 15, but thats without the spare tire on the roof rack. I'll looking into that crank sensor mod, thanks!
Great video! Sweet XJ
Thanks Josh! When you are ready, let me know and I'll help you build one for yours👍
How is the fuel management done? I'm used to seeing things like Hondata and Crome for tuning fuel trim and ignition tables from my tuner days, but I haven't seen much talk for the XJ.
Fortunately the stock PCM does a great job and managing the fuel with the bigger injectors. I used to have a built GSR motor in a 93 civic coupe years ago so I'm also familiar with hondata. Now I have heard there are guys that can tune the factory PCM, but since I'm not after every last bit of horsepower I havent pursued it. The torque was more important for me with this build.
@@cleanEG 97 up ecms are now supported on hp tuners
96 and up the ecm can be tuned
Hi, do you have anything left of the 4.0 engine? I would like to buy. I collect the same only zj in Russia :)
I'm wanting a stroker badly, after all my research, I think the research I'm looking for is how happy someone is with what set up they went with, reliability and torque is what I want, did I stick with factory set up on timing gear? How about cam style ? And di u upgrade oil pump ? a little more than what the 4.0 puts out will already be great of course , hopefully you'll chime back in in the future with how it turned out . Great content on this .
I absolutely love it! I've put about 2800 miles on the motor including a trip with all my camping gear, extra fuel, water, etc. The XJ was probably close to 5000 lbs. Several times I climbed 8% grades from 200 feet above sea level to over 4000 feet. I used to crawl in 2nd gear and struggle to get up the mountain. Now, I'm in 3rd gear (AW4 tranny) and can maintain speed (50mph) all the way up the grade. With twist and turns, that's perfect and I don't hold up traffic. Unloaded, absolutely no issue in 4th gear on any mountain climb. Overall, I am extremely pleased with the result and the investment was worth every penny.
Regarding your other questions. Factory timing set with a very mild camshaft. It's not a wild racing engine with a huge cam, degreed and built for high hp. I wanted to pass emissions testing and keep it as reliable as possible. The Mishimoto radiator I have has done an amazing job at keeping it cool. The oil pump is a melling provided in the kit from Russ and I am running a Mopar water pump, Mopar coolant temp sensor. Fan clutch is Napa oem XJ, not a ZJ fan clutch. Hopefully this summer when temps are in the 100s it still runs cool but for now no issues whatsoever.
Thanks again and I dont think you will be disappointed!
Max BitRate Films hi
@ 4:51 - What is up with the pan gasket at the timing chain cover? Oh, and where did your cool red valve cover go? Did you take the time to paint it red only to decide to go with Jeep's factory black instead? I liked the red cover. Either way, this stroker engine looks really nice. Congratulations! EDIT: Now @ 6:18 - The red valve cover reappears. WTH?
:) I used a spare valve cover during the install so I wouldnt scratch the red one. Are you referring to the fel-pro blue gasket?
Great video! Just blew up my 4.0 last weekend and have heard great things about Russ's engines. About how much did the stroker kit run ya? Also do you have any tips for removing those top bell housing bolts?
just pull the engine with the transmission. so much easier
My plan was to pull the engine/trans together, but in the end, I had a long extension with swivel socket and a buddy in the engine bay guiding the socket onto the bolt. I probably have close to $5k invested in everything, including all the small stuff I replaced along the way and a few sensors here and there.
Did you ever bother to have the stroker on dyno? Curious what the results were! I have an 89, so it’s pre-smog in Oregon😁. I need recommendations!
Do you know what head was used? Also what are your cylinders bored out to? Is all of your fuel delivery system stock and what are the major components you had to change?
The head was ported and polished by Russ with bigger LS valves. I think the cylinders were bored .25 over if I remember correctly. I have Bosch 24lb injectors. The ECU is still stock along with the fuel pump.
@@cleanEG Thank you. Very valuable information and great videos. Very solid and beautiful jeep.
What kind of psc steering do u have???
Building a 4.6 stroker motor where did you get the motor mounts that you used??
I picked them up from StinkyFab Racing here: www.stinkyfab.com/collections/xj-mj-cherokee-and-comanche/drivetrain-mounts-jeep-motor-mounts-xj-mj-cherokee-and-comanche
Hey bro had a question where u got the motor bracket that goes to the motor mount
The motor mounts are from SFR
beautiful engine must of cost you a small fortune to get it built. did you get bigger injectors or throttle body for it? and fuel pump? if not that may be your next to do on that "ENGINE" (you call it a motor but motors are electric lol ). Curious to how much torque that engine produces.
Thanks Christoper19691, and yes I should probably call it an engine instead of a motor but old habits die hard :) I do have bigger injectors, Bosch 24lb. I also have the intake manifold runners port matched to the head and the TB port opened up to 63mm. I also had the stock TB ported to 63mm as well to match. I'd like to dyno tune it someday but for now I'm just enjoying it.
It's technically correct to call a combustion engine a motor. But an electric motor is not an engine.
👍👌
Thanks!
Well was it wort it? How is performance vs the old 4.0?
It was worth it, and I'm putting together a follow-up video shortly with some results. My jeep weighs in at 5100lbs certfied on a CAT scale with camping gear, 10 gallons of fuel, and myself. Going up steep grades I can leave the AW4 in 3rd gear and maintain a speed of 55 - 60 mph no problem.
Do you know what cam you are running?and passing smog
It passes smog (cleaner than the original 4.0) and I have a custom spec'd Comp Cam provided by Russ Pottenger.
Can you add a link to all the parts in the kit you used?
Hi Rex, Unfortunately the kit Russ provides is custom tailored to each individual. He's very knowledgeable and will be glad to answer any questions you have. He has custom Race-Tec pistons in a variety of compression ratios custom made to his spec for proper quench. Depending on your needs he will put together a package based on budget, horsepower goals, driveability, etc. From full blown king of the hammers race engines to daily drivers. Hope this helps!
Rex Mandarich there a lot of companies that make kits for 4.0 you have to look online u have Clegg's there very good an others an um talken billet pistons and rods
Roughly how much was your project ?
Oh man, I want to say the entire project was somewhere around $5k. By the time I bought all the miscellaneous items and a few extras.
So that's it?
No report from the test drive????
Did I miss something???
Did you use a stock header???
I used a Banks Torque Tube Header - I released an updated video and I'm working on a third update. Hope that helps!
How much horsepower does have now ?
I haven't put the Jeep on a dyno, but I think it's somewhere in the neighborhood of 285hp and 315 tq at the flywheel. It was definitely an improvement over the stock 4.0. Especially with the torque going up grades.
What octane fuel are you running?
I run 91 octane, even though the compression is low enough to run 87 if needed.
@@cleanEG What is your SCR and DCR?
I'm ready to buy your Jeep - how much? =)
One million dollars. That's a dollar per hour of build time 😂
so did you get the computer reprogrammed?
I did not - still running the OEM ECU.
Titled : "Stroker build" yet shows no building whatsoever. Ridiculous.
