Hemi Swap 1yr Plan
#11
02-23-2012, 03:02 AM
I got some new info from someone on another forum who did a 4.7 to 5.7 swap. It puts the wiring situation into perspective. I asked...
He responded with some great info:
The more I learn about this swap, the better.
Also, thanks to HammerZ71, I know what I will need to turn any 5.7 MDS into a non-MDS motor. That opens up motor options. While I understand that I won't have MDS anwyays, it's nice to have it physically deleted instead of just programmed out. The lifters and yolks just need to be changed.. if I go that far, I might as well put a cam in while I'm at it. Now it's time to research Hemi cams.. yay more numbers.

I heard you used the 4.7 PCM, did you look into using the 5.7 PCM at all? If you did, what steered you away from it and how difficult was that route?
Did you just sit down with diagrams and swap over the connector, extend some here and there and what not?
What motor did you end up using, what year was it from?
Thanks for any infos you can offer, it will help me in the long and short of my own swap.

I looked into the 5.7 PCM but it was pretty close to impossible on the Ram due to the CAN databus in it looking for everything to match. Also I do not like drive by wire.
I did not even sit down with the wiring diagram to be honest. I put the 4.7 on the stand and removed the harness. Yanked the 4.7 off the stand, tossed the 5.7 on the stand, yanked off the 07 5.7 harness and then started connecting the 06 4.7 harness to the connectors on the 5.7 engine. I knew that the 5.7 engine would have a vacant MDS connector on the rear of the block. From there it was a simple matter of extending the TPS, IAC, oil pressure, crank sensor, and alternator wiring to the correct locations. The coolant temperature sensor, oil pressure sensor, alternator, and crankshaft position sensor had different connectors, but the wire colors and functions matched exactly between harnesses.

you're your own worst critic. what did you say anyways? lol
I think the viper would be fine width wise, it's just a super long motor. E-fan and remount the radiator on the other side of the support might clear it. i sure would like the T56 trans though, even though 6th gear would be useless in that aerodynamically challenged overweight beast.

Ok guys, I'm about to make the biggest, most expensive, purchase involved in this build. Just got to hammer out some shipping details and such. I'm getting an '06 Vin2 assembly line fresh with 0 miles, stored in a climate controlled warehouse.. would have been the one installed in a Ram or Durango, and it comes with everything but the ECU, catalytic converters, and accessories. purchase should be finalized by tomorrow.. hopefully.
I went this route because I like the idea of new, really, but mostly because I didn't want to wait for a super deal on a low miles on that I would have to get harness and coils on anyways.. this has plugs, wires, wiring harness, intake, TB, (will be replacing that) manifolds, starter, egr, all covers, intake, and bracket for AC/ALT.. so to have a working truck I would just need accessories, CAI, efan, spliced harness, program, mounts, and exhaust welded.
But I'm not stopping there, it will get cammed and I am looking into other mods I can do while it's out too.

too much wiring for that one lol. I can hide a hemi from the inspector (OBDII checks) but a viper will stand out like a sore thumb..

Yea headers will probably be custom. I heard one will fit for some brands but that extra loop that most have won't clear on one side as the engine is 3" offset. I can start with manifolds 'cause they are sure to fit and go from there. I was thinking about aftermarket log style manifolds, but that seems like a waste.

after i said the viper thing i actually took the time to look it up, and it requires some extensive fab to make room for the viper, so i wanted to delete both things, but apparently there is no deleting things haha. but you'd have a massive sleeper if you did it all. all in all good luck in your project

I will help keep it that way
Shipping has been hammered out, delivering it to the place I used to work, has a loading dock, forklift and such.

Ok so I have a bit of an update, no pics yet as I don't have anything yet.. but I just got this update from the warehouse that I bought the engine from, apparently they couldn't drop ship it from their supplier so they had it shipped to them first, and now to me.
TRAILER 558454 IS ENROUTE TO INDIANAPOLIS IN US
Left on: 03/07/2012 from COLUMBIA, SC 29210
Estimated delivery: 03/14/2012 to Destination SALT LAKE CITY, UT 84119
Looks like I will be able to drink my green beer around the Hemi. I love beer holidays...
Another big hurdle has been jumped tonight too. I was having a hell of a time tracking down a Mopar Performance cable driven T.B. 80mm, and I stumbled across an 80mm cable operated TB from BBK for the Hemi. I got in touch with Richard at Hi-PoTek and he's going to order it to see if he can bore it to an 85mm or 90mm. It will also be cheaper this way too, that MP TB was $575.. I'll pay much less this way and have a bigger bore
BBK has model numbers for an 85 and 90mm but they never produced them, so I bet they use the same block, so the 80mm should be easy to bore out to at least an 85mm.
I've also decided on a cam upgrade, I'll be getting a Comp XFI 260. It's a torque cam so I should have no troubles spinning tires even with my 3.55 gears.
I'm thinking that the motor will make around 410hp at the crank which should amount to 300-320 at the wheels. That will be with headers, cam, TB, and CAI. I'm hoping the tune from Hemifever will increase that.
