6.1 Hemi

Post by lastmanalliance » Fri Oct 09, 2015 10:29 am

Has anyone ever put a stock 6.1 HEMI into their 3rd gen?? Or is this even possible?

I'm pretty sure the 6.1 hemi is simply a stroked out 5.7 345 ci hemi.. It will bolt up to the 545rfe in the 3rd gen rams. I have seen this particular swap on the JK wranglers... Really not sure on clearances though. I know you would need a new harness as the electrical components are different as well as the orientation of the throttle body. I found this information online in another forum.

the 6.1 and 5.7 are the same basic motor, just the 6.1 is bored out, with different heads and a HUGE intake manifold with some big ass runners. you will need to modify the hood of the truck to get the height correct. as far as the motor mounts, im pretty sure they will be the same, but some cutting and welding should fix that up if need be. and for tranny, that im not too sure about. if you ahve a shortbed, shortcab, id go with a full srt-8 swap out of a charger for rwd, or super-skittle(grand cherokee) for awd, but the awd may be more work than worth.
your main problem is goin to be computers. the 5.7 hemi that is out now has a totally different computer that the 6.1(just wait till the next gen 5.7 comes out) the srt-8 motor has about 11 separate computers(pcm, ecm, abs, etc etc) whereas oyour 5.7 has 5, i think.

Like I said though i'm pretty sure the 545rfe will bolt right up to a 6.1 L.

I think the best bet is rebuilding and adding a supercharger at this point

I agree 100% lol anything Hemi is expensive to begin with... Hell used engines are going over $2000 it seems.. How many miles on your engine anyways? I'm up to 176,000 HA. She still pulls pretty strong and burns 1 qt oil every 3000 miles not to bad at all.

I'm at 153k. Just trying not to buy a new truck in the next 5-10 years. I like my 3rd gen and if I can keep her nice then I will give her to my son when he turns 16. It just seems like rebuild/upgrade is the only good option.

Nah I gotcha i'm the same with this wagon... Always said I would drive her until she turns to dust which ain't hard in the salt states LOL. Excited to see how long the drivetrain lasts I got up to 180,000 on my old 1998 Dodge 3/4 ton with a 360 original transmission until my buddy borrowed it and blew it up trying to get unstuck in a field... The hemi's are known to go over 200,000 miles I think you will be good especially doing a rebuild. Only thing I can recommend is keep up on your tranny fluid changes. Only real failure of the 545rfe's is pump failure due to filters clogging. :rockon:

You can get hold of a forged rotating assembly and stroke the motor you have for a few grand and avoid all the hassles of swapping motors etc. K1 makes a kit that seems quality and reasonably priced

I looked up the K1 kit. They charge $2078 USD. Seems a really good price for a good stroker kit. Way easier than swapping a motor. Good idea colibri.

THe 6.1 goes into the truck with NO issues. It will bolt to the trans. You will have to use your oil pan and front timing cover. (that's using the 5.7 intake manifold) If you want to use the 6.1 intake, you will need the adapter to bolt the front accessories on. Will also need to convert to an electric fan.... since you are moving evertything forward a couple inches.

A custom tune is all you need for tuning.

The 5.7 block and 6.1 blocks are not the same! The 6.1 blocks are still the most desired blocks to make big power, and since they are no longer made.... Their price tags will not drop.

So if I had a 6.1 long block I could bolt it in and a tune would run it just fine with stock computer?

Yes and no. Using the 6.1 intake manifold makes for more changes.....

I have access to a wrangler with a 6.1 in it and thought about buying it, parting it out and keeping the 6.1

I thought you would have to switch out your computer's and wiring harness. Could you stick with your stock computer and still be able to use your locker??

None of the wiring harness needs changed. (Unless using the 6.1 intake manifold, the wiring needs extended to the throttle body). The lockers should work as normal..... I had mine bypassed before I did the swap.

It is actually a very simple swap.
