project dakota motor swap
Hi I got a 2001 dodge Dakota 4.7 5 speed 2wd single cab short box. Current mods before teardown for body restoration and drivetrain build was third cat delete tune welded diff stage 2 clutch 3:73s 3.75" drop springs rear shackle flip (4wd hangers and Silverado drop shackles) srt8 intake 2008 manifold superchip tuned. Never got to dyno i just drove it but January 1st was the last day it ran I drove it to work and ripped the motor out the 4.7 had a smoking issue starting if you let it idle and gave it gas it would smoke same way my 5.2 did with the lower plenum gasket I tore it down and bore rings good heads look good and all so I pushed it to the side cause I've been wanting put a new front clip on the truck fix my bed and paint it so apart it came so far body works 50% done got firewall fixed paint underneath painted when I took cab off had frame painted even though it still had brand new paint and barcodes on it front clips painted. Well now come my drivetrain issue.the 4.7 I can't afford to buy pistons and rods right now to make over 325rwhp so I've been looking at seeing how hard it would be to put a 5.2 in there I dont believe it would bolt up to my tranny so i was thinking of using a v6 2wd Dakota tranny computer harness and modifying it like you would for a v6 to v8 swap but does anyone know if it bolt on motor mount wise cause I can get a powerdyne kit for 800$ for a 5.2 and that be cheaper to get me where I want then boosting a 4.7 I believe I've seen 5.2 stock bottom ends handle 400+ rwhp

You'll need another transmission for starters. The 45re isn't compatible with a 5.2.
You'll also need a new PCM and wiring harness. You won't find one for an '01 with a 5.2. You're better off using one for a 5.9. The fuel trim won't be perfect though.
The mounts are different but you should be able to get a set easily.
The 5.7 hemi swap might be an easier option.

No 45re in my truck its 5 speed so I was gonna use a 2wd v6 tranny

Was gonna use a v6 5speed 2wd harness and add for injectors like you would for a 3.9 to 5.2/5.9 swap

Is the frame side the same with the single bolt like the 4.7

Look online for an engine rebuilder that provides a warranty... If you have to go through the work of changing the tranny wiring and computers I would look into the hemi swap.. Will provide far more power stock than a 5.2.. Considering the 5.2s make like 230hp to the crank where the hemi is about 320hp(year depending).. Guy on here a few years ago got a motor online and shipped to him for like 200.00.. I would at least look into it
