99 motor vs. 2000 motor.

Th0r · 02-11-2010, 09:26 AM

Are there any differences with sensors and wiring, or can I just drop a 99 motor in my 2k and turn the key?

don't think so what motor are you putting in.

There is. Something with injectors and stuff. Il let ION or someone who know the 2.4 better chime in.

injectors on the 99 arte Multec I's and the injectors on 2000+ are Multec II's

I'm sure the block is the same, but I just want to make sure all the hookups for sensors and such are there so I can run it with my ECM. The injectors wont matter since they'll be going bigger.

starter will be slightly smaller in 00 but its switched over anyways, and injectors apparently are a lil different, but you are changing them. yes it should fit just fine.

is there any difference in the output?
1) just curious
2) helpful for future readers of this thread

actually it depends on if early 99 or late 99. My 99 has the 00 starter and the 00 knock sensor and the different injectors and ION's hp tuners was setup for 2000 and was able to read and write to my car but not smurfs 2000.

early 99 could have an egr, would also have different knock sensor, starter, and different injectors and they also used a different upsteam O2 sensor.

so to some up there could be quite a few differences which won't work swapping and others that could.

so if i read that right if it was built late i could put a 99 in my 01? if so then i could get it fixed alot sooner

that would make my other half happy since she is part owner of the car she would get to drive it again.......

you have a 2001 car? awesome. You need a replacement engine? awesome.

any motor from 96 until the end of the production run of the 2.4L motor will work, as long as it is in good running condition.

from your crap motor you will transfer over this.....

starter
fuel injectors/rail
intake manifold/throttle body assembly
exhaust manifold using the newer style exhaust manifold gasket

as was previously said, 99 was a year of some minor changes.(2000 cars occasionally getting shafted too w/ the older style goodies).. as mentioned already. which is why listed above is what you will be reusing on the replacement engine.

the only issue is the knock sensor will not thread into an older style block, & vice versa. One knock sensor is larger than the other. Everything can be remedied w/ an adapter nut that your sensor can thread into and the nut being able to thread into the block. It's a simple fix. Car will run fine. I had a 98 block using 2001 goodies myself. Before I figured this out I ended up welding a nut instead. I learn the hard way for your knowledge.

blammer! hope I helped. it's late I'm tipsy.

Ok, this is my deal.

My motor is fine, but I want to build it. I found a 99 motor that has already been build with a good portion of the stuff I want done to it for about the same price. I figured I could save myself a lot of hassle and vehicle down-time by buying that motor.

The guy who will be tuning my car was able to read it with HPT. I just want to make sure that should I install the motor, and of course swap everything over, can still work with HPT.

So all I'd have to do is block off the the EGR with a gasket, adapt the knock sensor and I'll be good to go?

Thank you Spyhunter. you have just made my search so much easier i was thinking that i couldn't use anything other than a 01

i know newbie mistake but i was corrected which i actually wanted.. and thor i wish you the best of luck

all you need is the exhaust manifold gasket for a newer motor which already blocks off the egr passage.

You're using your existing wiring harness and PCM, so the HPT should not have any issues with whatever motor you use. It doesn't care, it just needs a PCM it likes.

If you want to do a sick motor build that will be bullet proof. Hollar at ya boy.
