When are the hemi JK's coming out????

[jgrreed]

Hey Guys, I've been watching closely from north of the 49th for a couple years now, and can't wait to get my first AEV.

What's the timeframe on the new hemi JK's?? Will there be a 6.4L option?? What are the details of getting one to Canada??

Thanks,

[AEV Matt]

Just 6.1 and 5.7 for now. The 6.4 calibrations just don't seem sorted out enough to sell to customers for daily use. The sales guys are taking orders now for April deliveries. Keep you're eye on the AEV news section too, interesting stuff coming in the next few weeks.

Matt

[jgrreed]

Thanks Matt. What are the costs for the conversions???

-J.

[AEV Matt]

Pricing is as follows for all new components:

5.7MDS Turnkey - $17,999
6.1 Turnkey - $24,499

I know the sales guys are getting pricing together for used powertrains or if a customer wants to bring us a WK/XK drop out. As soon as its all together they will send out a news item on the AEV site.

How is the driveability and performance of the conversions compared to the stock 3.8? Are there any other upgrades you reccomed such as axles or driveshafts?

[AEV Dave]

Put it this way, up until we put a 5.7 in mine, It had about 2800 miles on it....2000 of those were the miles put on it when it was stock from Detroit to Montana. I hated to drive it with the 3.8. Now, I love it and it has about 6K on it. No hunting for gears, about 17 or so mpg on the highway (37" swampers) and its fun to drive. We just pulled the 5.7 out of mine and are putting the 6.1 in it for kicks, but if it were my everyday car, I would stick to the 5.7.

That can be offset with selling the 3.8 right or is that built into the price?

Well from what I have seen on this so far probably not yet. Burnsville Offroad has said that they are willing to give them away, so you probably won't get much for it.

[jgrreed]

Really hoping for a 6.4 sometime. If I'm doing something this pointless, aka pure fun, I'm going to do it as pointless, I mean as fun, as possible. Can't wait to see some other builds for ideas. Thanks for the info so far.

What about getting them into Canada?? Are you guys tight enough with Chrysler to have one sent to a Canadian dealership???

What gearing?

[AEV Dave]

In order:

The 3.8s aren't worth much yet because there is no standalone harness for them. We're working on that now also, the 3.8 would actually be a great motor in a buggy or an older Toyota.

The 6.4 is OK, but to be honest, not worth the added expense and headaches at this point.

I don't know what kind of laws are in Canada. We've done a couple in TJs for guys up there who haven't had any issues. In the US, the HEMI conversion can not be done on a vehicle that hasn't already been delivered to the final customer. Once delivery has taken place, the customer can have the conversion performed legally by federal standards (state is another issue), I would imagine that Canada is similar in that respect.

I originally had 4.11s in mine with the 5.7 and 37s, it drove great, but the MDS wasn't kicking in cause the loads were too high. Switch to 4.88s, all is well. I think the 4.88s with either HEMI is a good way to go if you have 35-37s.

[JeepinJon]

I am thinking that this may be the conversion for me once my JK arrives if there is not a diesel option for 2009. Do you know if the york air compressors for the 3.8 will also work for the 5.7 as well, or are their additional modifications needed. I would like to be able to run on board air, and all the JK kits are set up for the 3.8.

[AEV Dave]

No way on either!

[kntr]

Dave,
How soon till the 6.1 is done in your Jeep? I just cant decide between the 5.7 or 6.1.

[AEV Dave]

Its in, just tweeking it now getting it ready for Moab.

[Screamin Lizard Customs]

I found a home for this 3.8! A 1947 Willys buggy. Look for Gerry P. out there in Moab. Adam

can i ask few question:

1- what do you think of the dana 60 front and rear on a 6.1 JK ???

2- i heard that there are metal sheet axles better than dana 60, and they are used alot in the states for racing cars, So what do you think of those, are they really a better option ???

3- 6.1 and 6.4 is there really big difference in the power ??? and are you doing the 6.4 ?

5- Having a hemi 6.1 on a JK can i use a borla headers and borla slip rear cat-back ??

6- having the 6.1 on the 4 door JK what milage would a full tank give me ???

[AEV Dave]

Axles really depend on your usage. If you're in the rocks all day, with 37s and serious on the gas and use the JK mostly off-road, you probably need 60s front and rear. We'll install the rear 60 for expedition use (trailer towing, heavy weights, lots of very hard miles) but don't like the front 60 because of how much the weight affects on road manners. The 44s are very strong and will hold up to 95% of most wheelers needs just fine, even with the V8s. Basically if your right foot is connected to your brain, the 44s are fine.
Sheetmetal housings have been used in race trucks for years, normally with a Ford 9" based center section and gears. These housings can be built very strong and lightweight but again are overkill unless you plan on racing through the desert at 90mph and jumping...which the JK body, frame and suspension will not stand up to, if that is your plan, look into a purpose built pre-runner truck.
We won't be doing the 6.4 anytime soon for customers, the calibrations just aren't as sorted out as the 6.1 and 5.7 factory calibrations. We wouldn't want a customer getting something that fouled plugs if not run hard consistently. The 6.4 is more of a race engine that likes to be run hard all the time.
We have Flowmaster design and build all of our exhaust systems and they are excellent. I don't know if Borla would be willing to build you something that fit or not.
Milage on the 6.1 varies greatly. Around town, with 37s I get about 14mpg. On the highway with the cruise set, it gets about 16. Off road, its about 10. Keep in mind that the 6.1 requires 89 octane min. The 5.7 is considerably better and is the engine we recommend for customers using these vehicles for overland travel. The 6.1 is more for fun.

[kntr]

Is there a huge power difference in the 5.7 vs the 6.1? I know its close to 100 hp more but how about get up and go and towing wise? Can the 6.1 be driven as an everyday driver?

[jeep]

someone told me that in 2009 JK will be introduced with 5.7 engine , is that true ???

would the dealer introduce a 5.7 JK to the market ????

[JeepinJon]

So far Jeep has made no official announcement regarding new engines in the JK. I think we are going to have to wait until mid may when they release the order forms for the 2009's.

[jeep]

now back to the JK hemi 6.1 engine , i heard from lots of people that no one has the 6.1 computer programed for the JK, and that every body is using the 5.7 program.

so is it available or not ??? and does everyone have it or only AEV ???

Ive seen a lot of 6.1s in JKs. I have yet to test drive one though.

[jeep]

now i'm thinking to change my axles so handle the hemi 6.1 engine.

Its a 4 door Sahara, the car will be used in the desert (before i had a TJ and we used to have problems with its front dana 30 because if we do one small jump in the desrert the axle gets bent) so i want to solve this problem , some people tell me to use for the JK front dana 44 and rear dana 60 , but i'm thinking to use dana 60 front and rear , so what do you think ???

It is more of the wall thickness of the axle housing than the axle itself. I think as long as you get an axle that has a thinker wall used for the housing you should be fine. I know I am looking at the Currie Rock Jock Dana 60 axles in the future because they are retaining the 5x5 bolt pattern so you don't need new wheels, and I am not a huge fan of running locking hubs because then you need to get out everytime you want to run 4wd, and it defeats the purpose of having shift on the fly.

[scoutermike]

Thinking of trading up to a JK and getting the HEMI conversion. Are they done in Montana or the Detroit facility? Living just across the boarder makes it easy to bring in and pick up.

Last I knew they were being done in Michigan.

We do have true 5.7L and 6.1L JK programs.

I personally have serious concerns about running one engine of any type with any other engine controller. Maybe it works, but that's not something that we would offer even just for diagnostic or potential long term unreliably issues.

I know at EJS there was a swap kit shown for the 5.7 / 6.1 by AEV. How much work would it be for a garage mechanic to do this swap. Is there any welding, or is it pretty much take out the old engine, put the new stuff in? I know it will probably be w hile for this, but just trying to decide if I should start saiving.

[imajeepnut]

Forgive me if I missed it.....and I probably know the answer already...BUT....if AEV performs the HEMI conversion, will DC honor the lifetime warranty at any dealer? Crossing my fingers here waiting.....

I am assuming that it will be like other warranty issues where it the modified part is what causes the defect then no they will not. I know that the engines if bought new carry a warranty from Chrysler, and I beleive that AEV also has a limited warranty in place if they do the swap.

[Jdemonto]

X2, If the dealer finds that the v8 broke a rear driveshaft or axle likely it would not be covered. AEV does warranty the motor and trans and the conversions parts.

Jason

[AEV Dave]

Actually here's how the engine swap warranty works:

If you buy a turnkey conversion through us with all new parts, we warranty the conversion parts and labor for 3/36. The Mopar parts (including the engine and trans) have a 12/12 warranty.

If you buy a turnkey conversion through us with a used powertrain, we warranty the conversion parts and labor for 3/36. The used parts typically only have a warranty from whatever salvage yard supplies the parts saying that its a good powertrain.

If you buy the kit, all the parts are warrantied for 12 months.

Thanks for the clarification Dave.
