Differences in a 2000 and a 2004 3.4L

rckrzy1 · 10-18-2006, 06:02 PM

Thinking of putting a 3.4L 2004 motor, in to a 2000 3.4L. Are there any problems with doing this. Are they the same motor mounts, and everything else and if theres are problems what are they?

Sprucegagt · 10-18-2006, 06:23 PM

Should be no problem at all.

jaketuff · 10-19-2006, 08:47 PM

Only thing different is the PCM controls on the 04, and I imagine not much different at all. Mild tuning to improve efficiency (sp?) of the motor.

You'll be all good I imagine. Just need to get the PCM reflashed to match the VINs up.

Did Grand Ams have LS1 and LS2?

Thats what I heard 1999-2002 Grand am's with 3400 are LS1 and 2002.5 to 2005 3400 are LS2. But I guess I'm wrong

Your wrong. All 3400s are designated LA1.

You reminded me about 1 important difference. The pre cat O2 sensor is different between the 00 and 04 models. You will have to switch over your 00model O2 sensor.

The LS1 in in my GTO and all 1997-05 Corvetts (excluding the Z06 which has a LS6). The LS2 is in the 05 and 06 GTO and the 05 and 06 Vette excluding the Z06 which has an LS7. They are both V8's

Yah. 04 GTO is like the 5.7Litre and the 05-06 is the 6.0

Is there any reason I could not use the 2000 PCM to run the 2004 engine ?

And I do have hptuner so I can do changes to the 2000 pcm as needed.

If the only physical change to the externals is the pre cat O2 I can just swap
that.

Your 2000 PCM should work just fine with the swapped over O2 sensor.

Excellent, thanks for the info.

Also need to make sure the VIN#'s match OTW a code is kicked off iirc. The PCM will do fine from any year, the programming is the key... no hardware differences.

HPTuners... Has that made a difference in SOTP for the 3400? MPG work done?

Which Vin numbers ? The PCM will be the original from the car.

SOTP ?short for ?

He's not changing PCMs. So worrying about the VIN doesn't matter.

SOTP I think means "some of the problems"

rckrzy1 · 12-28-2006, 09:36 AM

OK, got a 2003 motor on ebay for $450 plus $140 S/H , I highly recomend these guys for a motor ( lkq Online ) . The motor arrived in TX 5 days after paying for it and there was a weekend in there too.

The O2 pre cat was different as already mentioned , and we also bought a motor from a impala , so we had to swap motor mounts, cam chain cover and the water heater lines.

The motor started right up with NO CSK , NO noise what so ever, the motor has alot more power.

The CSK was so bad you could easily see the oval shapes on the bottoms of the cyclinders and you could see the rings easily on 3 cyclinders, as in the pistons did not fit the sleeves at all, what a lousy job by GM. Looks like the 3 bad pistons where running very rich due to lack of compression.

Read up on the yearly changes for the LA1.

Though you may not have any issues...the newer 3400's have been improved.

Better sealing, better bearings, better gaskets, coated pistons.

It'll swap right in...but there are differences between yearly 3400's.

I'm unsure but does the 2000 3400 have a different EGR then the 2004, or is it just the 99 that has the odd one?

EGR's where identical.

slowbird · 12-29-2006, 09:23 AM

Okay then...must have been the 99's that had the odd EGR.
