Out of Curiosity... - 4/25/2008 2:24:26 AM    Shibby927 Posts: 742 Joined: 4/28/2007 From: Norwalk, Iowa (Living in Ames) Status: online What would it take to swap my 3.7l V6 for a 5.7l Hemi? What kind of parts would I need to buy? How much would I be looking at spending?  I have tossed the idea around for awhile but always thought it would be too expensive, but I have read that putting a 5.7l in wouldn't be too difficult.  I can do poor man's mechanics (oil changes, tune up stuff...) but I am not very mechanically inclined so this would be something I would have to get done professionally.  _____________________________ 10.2s at 130mph in the 1/4 mile!

There's a guy on the dakota-durangos site that swapped a 5.7 into his 2001 Dakota Club Cab.  It was a lot of work but he knew what he was doing and seemed to have a limitless supply of cash to fix all the problems that came up. He got his motor with like 17,000 miles on it from a junkyard for just under $2000.  I think I would go the same route, of course I would have my mechanic friend look at the motor for me. :) < Message edited by Shibby927 -- 4/25/2008 3:28:39 AM > _____________________________ 10.2s at 130mph in the 1/4 mile!

Never mind... i've been up all night long and my mind just clicked on that one. < Message edited by Shibby927 -- 4/25/2008 5:13:59 AM > _____________________________ 10.2s at 130mph in the 1/4 mile!

I guess you could say Owner like Truck...Truck like Owner... I dunno about the price being 10k but I bet for sure you'd be in around 5k or alittle more. I dunno much about the electronics with our trucks yet, but as far as switch to the 4.7, I would guess new ecu and such, new rad, engine, motor mounts, basically all motor compartment parts. Itd be less of a Pita to just buy a different truck with the 4.7 especially if you are lacking a bit of mechanical knowledge. Its quite a battle switching to a different size motor and getting everything to work like it use too. < Message edited by lghtngblt02 -- 4/25/2008 10:37:10 AM > _____________________________ 93 Dodge Dakota LE 2x4, 3.9L V6 Magnum 00 Ford Focus LX Sedan, 2.0L SPI (in reply to Shibby927) Post #: 7

The one i looked at was a gen 2 dak it has custom everything he had to do a SAS to support the weight of the motor. the cheapest route would be to find a gen 3 with the 4.7 in it. or buy a crate motor all ready to go and fab the motor mounts and such... you'll need a new ecu and all of that other crap as well. its alot of work and money. and you have to work all of the bugs out. too much headache for me... oh ya and it cost too much for a poor man like me lol!... _____________________________ 06' Dakota crew cab SLT V8 4x4 crew cab tinted windows Flowmaster exhaust.

RE: Out of Curiosity... - 4/25/2008 1:21:41 PM    ericemery DF Site Moderator Posts: 4093 Joined: 1/30/2007 From: Michigan Status: offline Well,  since nobody has tried to actually answer the question logically...   here goes nothing. lets say you went with a Donor truck.  it would probably be the cheapest way.  (can salvage Motor, trans, and engine harnes/cpu.) I have seen totalled rams at thw J/Y for around 6K Now figure in ATLEAST 80 hours of shop time for the install.  (I have heard of swaps going faster,  but the average time seems to fall into that time frame on many other vehicles. (IE Cavalier V6 swap,  Civic B18c swap, Silverado 454 swap...)    So that where I grabbed the arbitrary 80 hours. Around here,  shop time runs around 150-200/hr.   so lets go on the high side and say 200*80=16000...   but then lets say you find a shop that knows what they are doing and can do it in half the time...    so for 8 grand... you would still be in the 12 grand price range. So I would say,  just get a ram for that money...  http://cgi.ebay.com/ebaymotors/HEMI-V8-CD-CUSTOM-WHEELS-NON-SMOKER-REAL-NICE-TRUCK_W0QQitemZ280220126070QQcmdZViewItem _____________________________ 2006 SLT 4X4 Quad cab V8.

RE: Out of Curiosity... - 4/26/2008 7:23:33 AM    Racinartist Posts: 375 Joined: 11/23/2007 Status: offline It would seem easier, and more cost effective, to try to find a new 4.7 out of a wrecked Ram or Dakota. It might be hard to find since they've only been out 6 months or so, but 300+ HP with no mods, and the swap should be relatively easy considering that it's the same engine block, so one would assume the same engine mounts also. Just a thought. (in reply to Shibby927) Post #: 14

RE: Out of Curiosity... - 4/26/2008 8:23:55 AM    donkeypunch Posts: 67 Joined: 1/17/2008 Status: offline Just realize that you will have to obtain the wiring harness and ecu for a successfull install. Honestly, removing an engine and install is not what it seems. If you decide to stick with the 4.7L install, the nice part will be that Dodge has already gone through the fabrication to garuntee fitment. If you go with the 5.7L, you  (nor I) have any clue about the issues that you will run into.....because no one has put one in our trucks  yet. The shop that does the work will need to excell at fabrication and engineering. I'm sure you don't want that one guy that has R&I'd a couple motors that one time to take on the job. Honestly, unless you have a wallet and time, just get a new 08 Dak or maybe even the new 09 Ram... _____________________________ J.P. 06 Dakota 4x4 ST -Power Wire -Mopar Tow-Package -Mopar Skid plates -Mopar Tow Hooks 91 Eagle Talon TSi -2.4L, Eagle rods, Wiseco pistons, Brian Crower 280 cams, 1mm OS SS valves, Garrett 57 trim T3/T04E, Etc. ...traction ret (in reply to Racinartist) Post #: 15
