it would be a really hard swap to go from the 2.8 to a 3.8. one the 2.8 is a 60 degree motor and the 3.8 is a 90. i am going to swap the 2.8 for a 3.4 because as far as power the 3.8 isn't much more powerful than the 3.4 and the 3.4 is a very straight forward swap almost everything is interchangeable.
complete engine, wiring harness, and computers. you may also need the tranny if they are different because the computer needs to connect to the tranny as well and won't work properly if they're different.
you shouldn't have any problems as long as all the sensors and wiring are the same or switched to new motor.
Yes, But there is A lot of work and parts to change too. Tranny wiring harness most accessories motor and trans mounts computer You pretty much need to take everything out from under the hood and the computer and wiring and change it from one car to the other.
you need V8 motor mounts, bigger radiator, a turbo 350 or turbo 400 automatic tranny, a new driveshaft, the computer and wiring from the 350 fuel injected engines donor car and you should get a beefier rearend.
It's the same car so it will work as long as you make some changes like motor mounts, tranny exchange, and you will need the wiring harness and computer off the donor car.
YES
tranny is built in the motor case and is changed everytime u change oil
absolutely not. not without some kind of mods and all of the wiring harnesses and computers. also the tranny would have to go with the motor as the ECU must connect to both the tranny and engine to function properly.
If it is a 3.1 any 1992 GM motor will work. If you are doing a motor swap from 3.1 to a 3.4 Dual Cam engine it can be done but you have to change more than the engine. The wiring harness and ECM (computer) have to be changed. Possible mounts also. If you are swapping to a newer engine (say a 1998) you might have to change the wiring and ECM.
you will need to 2.4 tranny and they sell a motor mount kit that will make the engine fit to the original motor mount holes u dont need a tranny froma 2.4 the neon tranny bolts right up to it manual or auto works fine. go to modernperformance.com and buy the passenger motor mount adapter and u will have to cut the bottom motor mount to clear the oil pan. then the wiring u can use the neon dohc wiring and the computer. if u use the computer u need to change the 2 outer wires around on the coil pack and move injector plug #1 to#4 and move the others down one left to right. i have done this swap and its not hard to do if u can change a motor in a car. also the 2.4 srt-4 motor didnt come out till 2003 and if ur gonna us the srt-4 engine it is best to use the srt-4 tranny with it. I did a 2.4 swap froma stratus and put a srt-4 turbo on it and it works great. How much will this cost??
Check the fuse and the wiring.
get the fluid changed and a new filter put in the tranny and hope for the best, it's possible the tranny is on it's way out.
