What is the difference? Anything I should worry about? I have heard the 01s are just more reliable all around!

2001's are usually considered better. 2000's have old style block which some say is stronger, but it has an intermediate sahft, small port head like an 01, older motronic ecu, narrowband 02 sensor.

01's have new style 06a block with no intermediate shaft, vvt, wideband 02 sensor, probably some other stuff im forgeting.

the 01's are easier to tune and can run wihout an maf sensor. if your not planning on modding it, either one wil be as reliable as you want it to be. if your looking to mod heavily, id look into an 01

on a side note, I would go with an 01 or a 97-99.5. Reason being the 2001 is the most up to date version, has 180hp stock, runs without MAF. The older aeb motors don't have immobilizers so if you want basic mods and buy a used ecu with a tune, you can plug it in without any additional fees or hassle of mating the ecu to the car

Redline is talking 1.8T's (not the 2.8), so I will continue with that.

2001's also have slightly more horsepower on the stock tune. 170 vs 150. This is mostly because they push a little more boost from the factory: ~11psi vs ~7psi. Nothing neck-snapping, I assure you. The 2001 1.8T will have larger front wheel bearings (they use the V6 front bearings) which may make them last a bit longer. I've had both rears fail on my 2001, but not the fronts yet.

Pre-facelift ftw!!! (i'm no help)

No limp mode
dbc
shittier interior
2 piece head lights
no independent fog lights
Pre-faclift rear hatch/trunk (euro rear)
no worries when it comes to pixels


thats all i can think of.

North American B5's don't have immo's at all, just to clarify.

2000 Engine is the bastard child as the others have pointed out... If I were to do it again, I'd get a 2001 for the wideband option.

whats the difference in 2.8's? all i know of is the moronic changes.

I've had both rears fail on my 2001, but not the fronts yet.
ive had my front bearings go muliple times, and no rear bearings yet. im 01 also.

Well, apparently there is no rhyme or reason. The bearings will fail randomly, however they like, regardless of which you choose. lol

the best one is the one you find cheaper with less miles and a better history.... \end thread

How hard/would it be worth it to swap in the AWM or a AEB down the line?

its been done but it wouldn be fun. besides the motor, harness and ecu, theyre are other things like cluster and sensors hat make it not very fun. better off getting an 01 from the start

NO MAF you say. any benefits running no maf and any draw backs? wheres the map sensor?

Are you talking about just swapping engines? If so, that's not hard as long as you have some one who can cancel some sensors or eurodyne. But.. if you're talking about changing from narrowband (AEB) to a wideband (AWM) now that's a pain. There's a lot of parts you need from an AWM. I'm going though it and I just wished I would of just bought an AWM.

As for me - ideal would be getting an AWM block with an AEB cylinder head.

yeah first off no intake, just a filter. maf's can be tough to tune as well. you need the correct size and scaling. the engine can run more accurate with an maf, but its much easier to tune without them. as for the map sensor its located at the top of the stock intercooler.01's have them. aeb engines do not, so they must run maf's unless on standalone, which usually includes a map sensor anyways

not sure if its only the 01's but my 01 came with a Ko3s and is on a s4 frame.

s4 frame what does that mean? I have the same car.

neither of these are true. The k03s is debateable, but it's never been proven the turbo is different. Its the software that adds the hp. As for the frame, there is no frame. Its unibody. And its the same as an s4.

redline, you may be right. bought the car from my brother. took him over a year to find this one. he told me something was different about it. he said he had some frame number ran or something and it was same as a s4. and i thought the ko3s was a completely differently turbo, better parts, lasts longer, etc. again, i may be wrong as i know im a noob.

just looked it up, seems that the ko3s has a slightly bigger compressor. same as a ko4-001 for 2001-on

Nope. I wish it was that easy. Aside from changing the wiring harnesses, you have to change the pedals, throttle body, intercooler and I'm sure I'm missing something. I ran into a problem with my ABS, the AWM ABS is different. So I had to go back and get the wiring from my AEB. Since I'm not done yet I don't even know if what I'm doing is right. I guess I'll find out when I'm done.

That is from AEB, what about ATW, probably don't have to do pedals, t-body or intercooler, ABS, etc, no? Or are you talking about from any of the earlier B5s, 2000 included?

AWM has:
Motronic 7.1 (as is 2000, but anything 99 and down is 5.9, and 97 down even lower)
Wideband 5 wire o2
K03S turbo, basically k04 compressor side, k03 hot side.
2001.5 A4's all got celebration package, meaning they received S4 strut bar in the front of the car.
2001's also had bigger hubs, same axles as all 98-01 2.8 A4's, 00 and down had the smaller hubs.

Its by far the best year to go for, especially if you want to mod. My A4 was putting down around 400whp on a HTA3076 turbo and a built motor. Mafless file too.

ATW's also have a MAP sensor. Mine was tuned and is running without a MAF.
