I'm after some info on the Gen 3 Hemi crate motors .

I have a line on a full plug and play 6.1 - but ts the EFI version and I want to go with carb induction.

As we don't have MP dealers down under - the questions relate more to the product than the actual conversion -

1 - The crate 6.1 seems to not include the power steering pump, alternator and air con compressor - Is this correct?

2 - I don't want to run air con or power steering - so how is the serpentine belt set up without these components?

3 - The conversion I'm planning on will be using a carb fed Gen 3 using the Carb change over kit from Plum Floored creations

- Can I use the ECM that comes with the EFI crate motor, or do i have to swap it out for a custom one?

4 - Are there block hugger headers available for the Gen 3?

Hope some guys can help me out with answers on these questions - there may be more to follow but at this stage I need these answers.

Thx in advance.
 
I hate to be a dick but it was said already most of this info is on the forum you just have to look. But, I've seen a AC compressor replacement pulley available from mopar, I doubt the crate would come with any accessories, and I believe you would need to purchase a MSD Hemi 6 controller to run the spark and timing with a carb. Also do a search for info on plum floored you should avoid them at all costs.
 
Street and performance - offers block hugger headers and ps delete I think

Bouchellon- offers ps delete I think

Don't need an AC delete, just a shorter belt

Where does ya'lls steering box sit? And is the engine offset the opposite direction?
 
You might want to rethink buying from plumb floored creations.

Thanks UHCOOG - I appreciate the effort.

OK - so I'll need a P/Steer delete, anda shorter belt - thats not too bad.

To answer your question -

Our cars are right steer - but they used the US K frame .

They ended up with no room for the steering box on the actual K frame - so they bolted it to the frame rail. ...right in the way of where the header outlet is on your passenger side.

So for us this conversion would need block huggers or custom pipes.
 
give it a break, he's looking for information not a pissing match....agree to disagree and move on....
 
Moving on - and back on topic......

The biggest issue is finding information on reverting from a 6.1 EFI system back to a Carb application which is what I have to do (Unfo EFI is not a consideration for race rules purposes) .

The main problem I'm confronted with is :

- Can I re-use the existing EFI harness with the "manual/carb" ECM supplied by XV or S&P?
 
I think the main issue there is just knowing what plug each computer uses. If the XV/S&P computer is just a stock ECM that's had some programming changed I'd think you might be able to reuse the crate motor harness, but you'd have a lot of extra plugs you'd either want to cut off or tape away (injectors mainly). You'd really probably just have to ask XV/S&P if you can to see what computer they use. There's probably also a decent chance the crate ECM isn't a stock computer, but rather something Mopar developed specific for the crate motor just to be a pain in the *** (because I'm sure there's one wire different somewhere...).

As far as accessory delete stuff, don't waste your money on a fancy delete pulley if you don't have to. I can't vouch for a 6.1 without seeing it, but I know on my truck front cover 5.7 I just got creative. I bought a standard plastic idler pulley (like what is found on the tensioner), and made a spacer from some washers to get it in line with the belt and bolted it to a spare hole on the cover. Then just used a string to measure for length and went to the part store to get a belt. Took two tries to get the right length and tension, but it was easy enough and only cost $20 for pulley as opposed to the $100+ for a "delete kit".

You could just sell the plug and play stuff off to someone who wants to run efi, and use that money to buy the carb,msd ignition stuff .

What he said. Sell the stand alone setup (somebody would pay a decent penny for that since the stand alone setups are between 1400-3000) to pay for the carb, intake manifold, and MSD hemi6 controller and wiring harness. You will come out ahead this way and end up with a better product as the hemi 6 controller was developed for this purpose.

You might get away with running the stock srt 8 jeep manifolds/headers on the 6.1 as they are like a shorty header basically.
 
4dr4ever.....one more post that is derogatory in any way shape or form and your getting a vacation...any more pm's and your getting a vacation....steer clear of this thread completely or your getting a vacation...This is Your Last WARNING!!!
 
What's going on here?????????? if someone has had bad dealings with a vender we can't help a brother out and tell him???????? I think we still live in America ????? Well maybe again after November we can only hope!!!!!!!!!!! Steve
 
Thanks for the helpful responses - Ill use the MSD 6 - I wasnt sure if the 5.7 application in the sticky thread for Map63vette would work with a 6.1.

I guess I was too bound up over using the factory stuff when I don't need to.....

Do I assume the only other ignition component I'll need is the harness P# MSD 88863?

I'm not sure that's right, is there a different part number for a 5.7 harness (old coil packs) vs 6.1 harness (new coil packs- for new coil packs on 5.7 as well?).

Someone else will have to answer this one...
 
Which efi plug and play system ya got? Interested if your selling
 
I'll check And make sure the MSD harness works with the 6.1.

RJSJEA - if I buy the engine it's a late 6.1 MP crate hemi but it doesn't come with any controller.

I'd guess I'd be selling the intake, harness and fuel rails/ injectors.

Excuse me if none of this makes sense but I'm three days in to learning about Gen 3s.......

Copy.....usually when people say "plug and play" it means with the ECU/harness. No worries, good luck on the swap.

You can probably get about $500 for the intake,rails, and injectors on LxForums or similar forum

Good luck on selling em, I know I had to wait quite a bit to get rid of my setup, though I supposed you have the upper hand since you have 6.1 stuff. Once I thought about it I sort of realized that trying to sell a stock 5.7 intake setup was going to be interesting. Who wants to buy a stock part unless you broke yours, lol. I know what they're worth, but the market for them isn't exactly huge. Everyone likes 6.1 stuff though =P.
