The Jeep 4.0 Straight Six is one of the greatest engines of all time. But that doesn't mean that it can't be improved. Newcomer Racing shows us how to put together a big power, naturally aspirated stroker 4.0 Jeep engine without spending big coin. Check out their website here:

This thing is a monster of a straight six. It made 329.5 lb ft of torque and 304 HP! That's small block power out of a NA inline six that's smooth as silk!

You got it. A five-grand redline isn't exactly sexy, but it is practical on a off-road engine where you want to maximize low-end torque anyway. Plus, like I'm sure you noticed, the builder was trying to get good power on a real-world build. This engine is going to be used everyday, and longevity is definitely an issue. Lightweight stock springs minimize wear on the cam lobes and lifters, but they don't exactly help stretch the redline to the moon. Thanks for watching!

GT3582R LSVTEC EJ8 First. Rpm is directly related to airflow. This is an older bigger ci engine. It doesn’t need to rev to 10k rpm to make any power like crappy 4 bangers Second; stroker motors don’t help an increase in rpm. If anything the inhibit rpm. Thirdly; this particular type of build isn’t for a race car. It’s built for torque. The more torque at a lower rpm is more useable power. Reving the shit out of an engine is always the goal of a build.

@Brock_Landers 4 жыл бұрын

I had to edit my original post because I jumped the gun on what I said and didn't think about the 4.0s of the past. I made a comment about the 5000 rpm redline, but I didn't take into account the fact that the 4.0s don't need to rev high due to their ability to make torque. I've driven quite a few Cherokees and Wranglers with the 4.0 and even some AMCs with the 4.2 and they were always extremely reliable, extremely smooth, and they always produced alot more torque than people gave them credit for. Besides, in an offroad based vehicle, you don't need high revving capability, you go with an engine that makes good torque down low, which is why so many people love the 4.0 and is also why you hardly ever see a Jeep stuck. This option being available to the Jeep community who stick by their beloved 4.0 just makes it that much better. Once again, I let my mouth run before I saw the dyno numbers...it's hard to argue with horsepower and torque!

That's cool. It's always good to read comments that understand different engines serve different purposes, not some keyboard warrior yelling that if an engine doesn't have twin turbos and make 1,500 horsepower it's junk! Thanks again.

@@Welcometofacsistube You're right, I am an import guy who has a 612 whp Civic coupe and ran my mouth before I took into consideration what this engine will be used for. My turbo 1.8L DOHC 4 cylinder revs to 10k rpm because it was balanced and built to make power that high, but my Civic is a drag car, not an offroad capable vehicle. That being said, this Civic is my 54th vehicle since I was a kid, and the other 53 were a mix of imports and domestics which included cars like a 800 HP 74 Camaro Z28 that my brother now owns, a 70 Buick Skylark GS, a 69 Roadrunner 383 4 speed car, a 70 Charger that I built a high compression 440 with a 4 speed for, but I've also owned Eclipses, Eagle Talons, a turbo 92 Acura Integra that made 412 whp, and even an AWD swapped 92 Plymouth Colt hatchback that I swapped a fully built 4g63t into that made 500 whp and would destroy Corvettes. I've always been a fan of a good build, but more importantly I've always been a fan of the underdog, and it doesn't get much more underdog than a lowly common Honda Civic. All in all, I just like horsepower and going fast on or offroad.

The first one I rebuilt came in and I assumed it was just a 4.0 liter engine because it was a 4.0 liter block . When I installed the first piston and turned the engine through the top ring came out of the cylinder . I had to order the pistons through the company that built the pump . They never would or could tell me what c.i.d. the engine had .But it had a different crank and rods than any jeep we had ever worked on before . The crank was forged steel and the rods were regular I beam rods but were very different from a factory rod . The piston looked like regular 4.0 pistons but the pin location was higher . Since then we have rebuilt 2 more of these . Always thought jeep folks would love to get a hold of one of these engines .

(I literally just looked it up) Pretty insane that those engines pumped out 190HP from the factory when most V8's were still only at 220 at that point, and in the early days (late 80's) were still only putting out 135.

@dawabbitt3079 Жыл бұрын

190hp / 6-cylinders = 31.66hp per cylinder. 220hp / 8 cylinders = 27.50hp per cylinder. That's a difference of a mere 4 hp per cylinder. Far from insane.

Why not start the dyno at 1500 rpm ? Alot of us would like to see torque numbers from 1500 to 2500 rpms as well

@AB-80X 4 жыл бұрын

You never run the engine at wide open down there. And if you tow something that lugs your engine down that far at wide open, you need to revaluate your setup, because that's not how you use an engine.

@TheHorsepowerMonster 4 жыл бұрын

It is really hard on an engine to put in on a dyno at start a pull that low because the pull is always at wide-open throttle. So to protect the pistons and rods, most engine builders won't start a pull until at least 3,000 rpm or so. Hope that helps!

Q-Jets where as big as 750cfm on a smogged out 350 yet, you could carry that Q-jet all the way to around 700hp if you knew how the carb worked.
