has anyone DIY turbocharged their 12/13 jk?

i know about the forced induction kits that are out for the pentastar engine but I'm not even remotely satisfied with the results that I've seen from people that have installed them, so has anyone (particularly loaded with money) made their own turbo systems for the jk? just want to see what an already impressive engine is capable of when it has serious work done to it.

this isn't an invitation to the "why would you do that" or "its already powerful enough" guys. we know. we don't wonna hear it. thanks for your input in advance because i know you're eventually gonna show up.

by the way I've seen a dyno for a v6 challenger that was pushing 379 hp to the wheels so this isnt completely crazy talk, just whimsical thinking for fun of course.

I think with a ripp for example we would get close to that too, but the wranglers loose lots of power in the drive train due to the 4wd...

i think a lack of aftermarket is the biggest culprit. this powerplant deserves more credit

I thought of going that route but stopped due to not being able to submerge the turbos in water while offroading. I was told the fast temperature change of putting hot turbos into water would shorten the life of the turbos very quickly. Hopefully I was told wrong because I would like to add turbos.

What about the aftermarket kits didn't you like?

I'm considering a RIPP myself for my '13 JK.

Well thats definitely true thadeus, turbos reach 2000 degrees in some cases depending on the performance level, but there are ways to avoid it. For example if some way was possible to bring it higher up in the engine compartment like they mounted the alternator at the top. But honestly ive seen humvees completely underwater so theres gotta be something. Ive also considered one of those cheap thermal turbo wraps, it would slow down the dramatic temp change as the water takes longer to get into direct contact and becomes heated on its way in.

As for the current aftermarket systems, they are way more expensive than DIY and theres just no joy in it. I could have bought a 600 dollar muffler but i made my own cat back with a 90• elbow and a glass pack.

I was always a small block chevy guy n ive seen 500 horse diy turbo iron block 5.3 lq's built in total for less than the price of an ls1, and less than the headers for an ls1 as well. Its all about the creativity.

Like you said you considered it, so you must be hoping somebody has a story to tell

Are you looking at turbo charger or super charger? On a jeep I'm not sure I would even consider a turbo unless you want to street race it. Turbos give you more horsepower in the upper end where super chargers give you more horsepower and torque at the low end which is where you are working most of the time off road. I also don't really see "cheap" way of doing this. Leaning towards super chargers, by the time you add up all the new parts, it will still run into the thousands. The best place to save money would be to buy the kit and install it yourself.

From following the forced air crowd, modern engines with computers aren't friendly to the old shade tree bolt anything on to make it go fast crowd. Companies like Ripp spend years trying to make a force air unit work with a particular engine. Forcing an air fuel mixture into and engine and getting the computer to understand how to run properly is a lot different than dumping the resulting exhaust gasses out the tailpipe.

The reason why you aren't that impressed with the systems that are out there is that those companies try to error on the side of safety and reliability. I'm sure the right person with the right parts could push well over 400hp out of the engine but I also imagine that the engine isn't going to last long. If you have the money, do it and have fun. It makes for a great toy but in the big picture it is an awful lot of money per horsepower and if I wanted something that puts out 350+ I would buy a second vehicle.

Sorry I started getting off on the why would you want to do it tangent. I got my 3.6 with a supercharger already on it at book value. The supercharger makes it a properly driveable jeep on road pushing larger tires and such. I couldn't imagine the same jeep without it. It would be a dog. The supercharger serves almost no purpose off road for the average trail going Joe when you are rolling along at 10mph and less. That all being said, I wouldn't spend the $6k for one.

I've considered putting a turbo on it, but decided a super charger would be a much better choice. Since I like to offroad on sand dunes fast, i want the power right off the line, no waiting for the turbo to spool.

Turbos are really easy to install though......would only take a weekend and a couple hundred bucks with junkyard parts.

There we go now we got some conversation blooming. For sand it wouldnt be bad or mud. Snow can be smooth but power isnt really needed in that case.

This all came up because im on 32's with 3.21:1, i love the gas mileage while still having pep, but if i wonna have 35's or 37's i need more power. I know i could put 4.10:1, but i wanted to see if anyone else has done somethin along those lines

Prerunning is fun too, more applicable to the 4 door guys though i suppose, once youre off the line and past the lag issues turbos are pretty useful

the way turbos like gears 3.21 with 37"s would be the hot set up...

why would that be more applicable to the 4 door guys?

2 door wheelbase is a bit short, more for quick turns. Long wheelbase is more stable, good for long highspeed rough terrain

What if someone owns a 2 door simply because they're awesome? Or possibly to discourage people from asking for rides?

No, not by a longshot. Turbos are much more complicated to setup correctly, which is why there are no companies that make kits...they would cost 2-3x the price of a supercharger setup. On 2012+, turbos would be EXTREMELY complicated since the manifolds are part of the head.

Michiganadam i agree thats why i own a two door lol and i live in NJ where if im lucky to find a spot its tight trails and rocky soil so i stuck with a maneuverable climbing billygoat rather than the steady long 4 door.

Some people say they put the manifolds in the cylinder head because eventually the pentastar will be used in a twin turbo car thats coming out later on, but we cant see the future

One thing we do know is that eventually there will be prerunners and hill climbers and even the gigantic undrivable monster jeeps with 6' tall tires built out of these pentastar wranglers

I was referring to the turbo lag. Heard of it? You need a healthy dose of exhaust gasses flowing through the turbo to get it to spin up before you get a decent amount of boost and get the power flowing. Superchargers run from a belt tied directly to the engine and you get the kick immediately.

That is why a turbo really does you no good in a jeep. When jeeps are built to 4-wheel up a mountain at little more than idle speed, the turbo will give you nothing at that time.

I see a lot of videos where people have modified jeeps and are blowing corvettes or whatever off the road. My question is why? I can use a pipe wrench to drive a nail but why when there are far better tools for the job?

Superchargers make linear power, meaning, they make most power on the top end, and very little on the bottom. Turbo lag can be easily mitigated (where supercharger behavior cannot.) If you run the correct size turbo, and a modern one at that, you will have almost no lag. Lag is generally a problem on high horsepower vehicles (like the 1500hp supras.) A moderately sized turbo can begin making power at 1600rpm with full power achieved at 3000 on a 3.6L motor. A supercharger will never be able to accomplish that. My 2.0L S2000 makes power starting at 1900rpm with full boost achieved at 3400rpm all the way to 8900rpm (it's starts to lose power from 8900-9120 redline, but a very small amount.) If I put the same turbo in a 3.6L V6, it would spool even faster. It's all about putting in the right turbo for the job. 90% of people that install turbos on their vehicles run the biggest one they can fit, so they can brag about their dyno papers, but in reality, unless they are on a dragstrip AND in the right gear, they are useless. For a Jeep, a smaller turbo would be ideal, so that you have power instantly, and more importantly, down low. If you haven't driven a modern turbo vehicle, I urge you to drive a new 911 Turbo. No lag whatsoever.

Not to mention modern turbos are starting to reach 300,000 rpm so itll do a decent job feeding a 6,400 rpm redline, especially if theres two tiny ones.

Obviously a diesel is completely different but the basics do apply, theres a reason the most powerful heavy duty trucks are turbocharged, and theyre meant for low rpm work..

Its not that crazy of an idea, look how many people started turbocharging the old 4.0s. And when i lived in japan all kinds of people ran straight 6 turbos in VERY LARGE lifted toyotas. They trudge through jungle swamps in okinawa and very steep hills. If its so popular there, they musta figured something out.

Like i said before its only so long before you start seeing hillclimbers and prerunners made out of these pentastar jeeps. I guess im (and a few others are) thinking well ahead.

The problem is cost. Turbo kits generally (assuming there isn't anything special like the JK manifolds to deal with) 2x more expensive to get right than superchargers. The supercharger setups are about 5Kish for a JK3.6, which means the turbo kits will run north of 10K EASILY (more for manuals.) For a company to take the time to R&D the kit vs the amount of kits they sell would be a hefty gamble. Sure, a proper turbo kit would beat the piss out of any supercharger setup or a hemi conversion, and it will cost 1/3rd of the hemi kit but the big dollar motor mod market on JKs is fairly small. A nice twin turbo watercooled setup would easily put down 400/400 at the wheels on a pentastar (which would be VERY VERY conservative) but again, it will cost an amount of money that the sales numbers just wouldn't be there.

Unless you have serious tooling, are an expert welder, etc, you ain't DIY'ing a turbo setup.

Is it just me or does that sentence totally contradict itself?
Superchargers start building boost right above idle... Perfect for offroad.
