Well i decided to do this conversion. And have been researching quite a bit and I am sure I can tackle this project. Only one question have you guys figured out what to do with the brackets for power steering and ac including belt tensioner? I know that the alternator bracket does fit. but i want to keep my PS and ac any ideas? Any advice would be appreciated.
 
The passenger side motor mount doesn't work, you will need a bracket made

the lower water pipe will need to be creatively held to the block, since the bolthole doesn't bolt up right

the dipstick will need to stick between header runners 2 and 3. Check the oil on a cold motor only

oil pan doesn't work well with the exhaust. Can be modified by cutting support ribs to make work with the crossmember, but for the exhaust, I am at a loss. Custom pan necessary

PT Cruiser alternator bracket works (can't remember the belt size)

must use underdrive pulley

recommend sandwich adaptor and oil filter relocation due to crappy location

custom ps and sc brackets need to be made, as well as a way to tension the belt

starter requires some notching of the bracket that holds the lower water pipe in order to bolt it to the transmission

the 4 corner head bolts must be from a 2.4, not a 2GNT, as the 2GNT corner head bolts (4 of them) are too short to meet the threads in the 2.4

2.4 oil pan gasket is needed

the main seals from the 2.4 are different then the 2.0

I recommend removing the balance shafts. They are on the bottom of the bedplate and can be removed by pulling 4 bolts and cutting the drive chain. There is now an oiling hole that must be blocked. I recommend tapping it and screwing a bolt in there, using red loctite

I also recommend baffling the oil pan if you remove the balance shafts. there is now a 6.5 qt. capacity in the pan which is too easy to slosh around.

2.4L valve cover doesn't fit well. Not sure if silicone sealant would fix this or not.

2.0 sensors (oil pressure, knock, and crank angle sensors) must be used. The 2.4 sensors don't fit the harnesses. Must get creative on knock sensor placement.

coil pack must be rewired: switch the outside wires

cam position magnet must be removed, the location nipples filed off, and replaced, turned counter clockwise 90 degrees.

Injectors must be rewired, move 4-3, 3-2, 2-1, 1-4.

This is all that I can think of off of the top of my head. I would not recommend this swap to my worst enemy.

GOOD LUCK HOPE you know what you are doing
personal I would not even try to attempt this swap
save your money get a stroker kit
 
Ha ha how many times have you posted that exact response BC when I searched that one comes up every time. Thanks for the reply but I know everything that needs to be done and I have the time just have to find the money! What I have found with my research is that the passenger mount does work 3 of the 4 bolts fits you just have to cut the 4th one out and weld it were it needs to be. The only thing holding me back is the brackets for my accessories, and belt tensioner.
 
you dont need accessories :p
I dont have any acc. on my race car
wouldn't you use the 2.4 tensioner for the timming belt
I post it alot because once upon a time I was going to do this swap BUT for racing i decided to stay with the 2.0 so that way I could spin it higher
