Hey guys,

So exactly like the title states I want to buy a 2.3L Dura to build and then swap into my '05 with the 2.0L. Any advice on where to get the 2.3L motor? Also, does anyone have a link or information on completing the swap?

Thanks! [ffrocks]

Best chances are to watch craiglist for a parted out 2.3 car. Or if you can find one at a junk yard. Just with the junk yard its hard to know if it is a good motor or not.

I believe the harnes is the same, and all you need is the ECU.

I think all you would need is the ECU an motor to do the swap + what ever is missing on the motor you bought, like the alternator, AC compressor, power steering pump, ext.

New motor complete.

I'm going to check out the local salvage yards to see what they have available.

I appreciate the link but I do plan on building the motor for high boost. So I don't know if buying a completely brand new motor is the best idea since I will be taking some of it apart and putting performance parts in it.

Thanks for the input guys! That should help a bit. I'm just trying to find the best way to do this.

I believe the transmission is the same correct? Mine is the MTX-75.

trannys are the same.

Thanks. I thought they were but just wanted to check. So let me make sure I have eveything right. As long as I find a good motor and get the ECU I should have everything I need to complete the swap.

yep, o an i forgot you'll have to have new keys programed for the ecu.

You dont need a new ECU. Your 2.0 ecu will work fine, it just has to be reprogrammed.

Also, you need a 2.3 passenger side motor mount and the dipstick will need some modifying or a 2.3 dipstick tube will be needed.

As in door keyless remotes? Or the actual starter keys? Cause if it's the remotes I don't have those now so I don't think that I would need them.

But if I'm replacing the motor entirely with the 2.3 wouldn't the dipstick tube already be there? But I will be sure to get the motor mount. Any good places to look?

The PATS looks for a match between your key and your ECU. Since you would be reprogramming the old ECU, I'm not sure if you would have to reprogram the old keys. May very well have to.

a tuner should be able to tune the ecu to use the 2.3 motor i have seen it done a few times

And why the motor mount swap that is something i have never heard when someone has done swaps before

So depending on the tuner I may not have to get a new ECU? Also, I'm still a little confused on the key thing. Is it the keys for the ignition or thr keyless remotes?

The transponder in the key will need to be reprogrammed. As far as the motor mounts go, You're building for high boost, so screw the OE ones anyway. Sounds like a fun lil project. I'll be looking for Your build thread[thumb]

Getting the keys re-programed for the ignition.

But now Im confussed, if you dont have to swap the ECU, why would you need to get the keys re-programed?

SYZ or HonHon, can one of you guys who have done this swap answer this?

I will be most likely replacing the mounts with better aftermarket ones to handle the power coming out of the motor. Thanks. I'm excited to get this thing underway. Just need to plan what parts to buy and find the motor and I can get started.

I'm just as confused as you norcal. First, since I will not be using power locks does getting the keys re-programmed even still apply to me? Or if I can get the ECU tuned to work with the new setup will I even have to do this?

here i think i can help ya out a little.. see your key has a chip hidden in the plastic... when your key is close the ignition the RF ID says ok i know this key and it matches the one i have in my ECU... so when you turn the key to start it starts... if you didnt have a matching RF ID in your key that the PATS system didnt like... you would turn your key and the car will not start.. no matching ID, no start.. the key needs to have the chip match the ECU "key code" inside it.

Say you went to a locksmith and had a key made as you would a house key or what ever, it will not start your car because its missing the RF chip.

PS I too will be watching your build. I am almost done paying of my car 2 years ahead of schedule... so I spend most my time on FS looking (drooling really) over parts, and trying to find Cosi parts that for some reason you cant find any longer. and building the killer 2.0. how ever i may switch to a 2.3.

Thanks! That makes more sense now. I need to find the motor first before I can start building it obviously. I need to take the time and go to my local junkyards to see what they have. I've been told I can find one with around 40k miles on it for $700-850. That's only 7k more miles than what my 2.0 has. And once I get the new motor built I can sell my 2.0 for a couple hundred and use that for parts. I may start ordering parts soon. Still compiling a list of what I want to get but I am dead set on getting this project under way. I may complete a few smaller mods not engine related before I get to the brunt of this build but we'll have to see what happens when I get the money to start buying stuff. Christmas kinda tapped me out for cash. Lol.

So, will the 2.0 ECU and wiring harness work or will I have to buy all that as well with new keys?

wiring harness is the same and the 2.0 liter ecu will run the 2.3 , but if your going for built turbo and stuff ur gunna need a tune anyway so u will be fine.

Ya I plan on getting a tune anyway. Probably from tom for a temporary solution until I can find a dyno place to tune it.

i believe the dipstick tube needs to be modified slightly. If you are replacing the ENTIRE motor, like getting a crate motor, then i suppose it won't matter. a lot of times you just get the long block

Maybe I will just make sure I get the oil dipstick when I pull the motor. Is there anything else to know that will need to be modified?

whoops, sorry for the late reply, but I think someone else already answered it anyway. But for clarity- you would not need to reprogram your keys if you retain your original ECU. IF you did retain your original ECU, then you would need an Xcal to reprogram it for the new motor. But if you were just doing a straight swap from a 2.0 to 2.3 with no addition of ECU tweaking for performance, then swapping the ECU along with reprogramming the keys is needed.

Just remember to get a passenger side motor mount for the 2.3, otherwise, you might have to add some fender washers under your 2.0 mount to raise the attachment point to the correct height.

Ok. So if I am planning on building it for performance, I will need an Xcal to tune the car for the performance. But will not reprogram the keys.

And if I just do the swap with no tuning needed I will need to reprogram keys correct?

Thanks for all the info guys!

This is what i don't get since i have done a few 2.3 swaps and as long as ur going with a 2.3 motor the motor mounts the same. Which is why when u order an after market mount it has one number for the mount. i guess u could order the mount but ive done at least two 2.3 swaps on built turbo'd car's and never once need to swap the motor mounts

yes correct. if you swap w/ no tuning you will also need the ecu from the 2.3 car.

yeah, i am actually repeating what another guy documented when he did his 2.0>2.3 swap. When I did mine, I was also installing a VF poly passenger mount. Everything lined up fine- I see your point about there not being any differentiation among aftermarket passenger side duratec motor mounts.

Thanks so much guys. This really helps. I think I am understanding it all. Now just to start ordering parts and the motor.

See if you can find an ST in a junkyard somewhere and swap out the drive train.

Jeff

What's the difference between the ST drive train and the one in my zx3?
