2.7 vs 3.5 engine swap
I have a rod knocking in my 99 Intrepid 2.7 engine. I have an opportunity to buy a 3.3 from a Dodge Caravan. Can anyone tell me whether those two engines are interchangable? What do I need from under the hood ie: computer, wiring harness, etc.
I posted this question on the Dodge forum and didn't get a response. Hoping I would get a responce here. Thanks, jfc |

Re: 2.7 vs 3.5 engine swap
These engines are not interchangable. The caravans 3.3 engint is transverse with the transmission. The Intrepieds is longitudenal with the trans. Two diffenernt things.

Re: 2.7 vs 3.5 engine swap
In first generation Intrepid's, they ran a 3.3 liter, 1998-2004, they had the 2.7 liter. Bizzy102 is right, it's not going to work, if you had a '97 Intrepid, then yes, same motor just needs mods to the intake manifold. Depends on how much money you have available but there are a few options you have: 1) find another 2.7 liter and stick it in their; either rebuilt, brand new, or used [personally, I wouldn't go used, it could be in worse shape then your engine currently is] 2) Get a 3.2/3.5 liter motor and stick that in there. You'll need to do some mods as well, like reposition your A/C compressor, power steering pump, you'll need a new computer and that should work for you.

Re: 2.7 vs 3.5 engine swap
You can use the 2.7 computer with the 3.2/3.5 conversion.I have done it this way with no check engine light on after hearing it run.Tha radatior is differant too.The 3.2/3.5 radatior has oil lines going to the radatior,The 3.2/3.5 throttle cable is longer and the heater hoses are differant too.I have ran into this too.If you replce the computer with a new one,you do not have to go to the dealer.The Mastertech scan tool from Vetronix will program and burn the vin in the new computer.Here is Vetronix's website, www.vetronix.com
