1.8T from B5 to B6 ??

[Dreamert]

I read there is a diffrence in power output from the B5 1.8T engine to the B6 1.8T.

Now, what diffrences are there to explain that ? is it only in ECU programming ?

One wild guess, say I buy a B5, once I get it reflashed or chipped, can I see the same output as say a B6 with the same treatment ?

Or is the intake/valves/cams/turbo and whatnot restraining the B5 1.8T from getting to the same level as the B6 one ?

They are both slow as hell, thats all I have to say.

[kwik_shift]

I think some of the K03's (fan blades)were different in the older B5's compared to the B6's, and maybe the engine code. Not 100% sure though.

Technically, 1.8T B5s can move faster than 1.8T B6s since B5s are lighter.

I'm not aiming for pure acceleration, I allready have an SRT4 that I fiddle with for that purpose....this is for a daily drive...but I'm quite concerned in buying a B5 because of the lame 150hp the 18.T puts out....especially coupled to an AWD train

I just want something taht goes by without feeling it streching to his last trend on every move...

Look for an 01 or 01.5 B5 A4 and you'll get the same power output that B6's have.....in the last year of production, the B5 A4 came with 170hp from the factory, while the older models had 150hp.....But generally speaking, both the B5 and the B6 will have similar power outputs given the same treatment (chip, exhaust, test pipe, etc), but the B5 is a lot lighter. However, the B6 does have the option of going Stage 1+ and the B5 does not

Depending on the motor, there are differences in heads and which case the intake manis are a bit different, blocks have slight differences in some instances. B6's use a return-less fuel system. So short answer they are the same but different.

You almost have to buy a chip if you have that motor. Without one you cry every time you get on the throttle.

I owned a K04 B5 and a GTRS B6, The way i look at it the B5 should have had that turbo stock, and the B6 should have the GTRS stock, but that is not the Case.

the B5 in quattro and a 2000 or 2001 is a nice compromise, as they are getting cheap. But if you have any ambition of larger than stock turbos i would reccomend the 1999.5 because it has a better flowing head, larger Intake Manfold, Drive by Cable throttle (easier to modify, tune, piggyback standalone etc.) and has the more current head light and taillights.

but if you want to have a good power and reliablity go with the V6 in any year or body style.

You said you already have a High Power Front Drive turbo, if you think about hooking up similar power with AWD you will be addicted and not drive the FWD. just food for thought.

A 2002 B6 with 1.8T quattro is less than ten grand then spend 3 grand on a gtrs, and you should be happy for a while.

How can I make the diffrence between a B5 with 170hp and one with 150hp ?

VIN maybe ? what to look for ?

How considerably lighter are they compared to B6 ?

[durfA4]

1997-1999.5 are 150hp the AEB motor code with a throttle cable
2001-2001.5 is the 170 hp the AWM

[durfA4]

oh the a chip will run you about $300 for the increase in boost and timing, and the B5 weighs about 3200 where the b6 weighs about 3500 plus or minus different options and such if you search on audiworld there is a model year guide.

stock is dog slow and I want to shoot myself on the highway on ramp. The problem is I dont want to push anything to it's limit and have to spend a few grand on a new engine. How mush less reliable is my car with a gtrs compared to stock with the basic revo setup?

[JumboBlack1.8]

Why don't you just save urself the effort and buy a built B5.....look for BernB5....he's selling one with a scat rods, custom paint job, refreshed short block, ALL supporting mods and a GT3076 for $12k I think.....Thats the price of a well maintained dealership-bought stock 2001 1.8T A4 with low mileage.....well worth it, if ur thinking about speed and power....cuz either way, no matter what stock A4 you end up buying, it'll still be ASS slow

Well that car looks amazing but the thing is, I live in Québec, like 7hours north or the border....that makes for a hell of a drive to buy a car.

My goals aren't to get it fast, just keep it fun and reliable. From what you guys told me so far (thanks a lot, I appreciate every input), a 2001.5 would be the best I could aim for: 1.8t with 170hp and 3200lbs.

Now, I'd maybe go for a reflash or chip to boost it up a little bit and keep it interesting in the snow (of which we get A LOT over here, like a foot-deep and over by times) as well as keep it economic (in gas).

So, how can I go and make sure one has the 170hp engine in it, any distinctive marks ? accessories placement ? trim ?

[fitch303]

Why not go with the b6 platform? you said you did not want it fast and the b6 is not that much heavier but looks 10x better. Also because it is the newer body style it wont depreciate quite as fast. Also from what I understand the b5 has a quite a few problems that had been worked out on the newer b6.

only 300 lbs? thats really not that much.

[J-jizzle]

only 300 lbs? thats really not that much.

Try to loose 300 lbs on a b6 with it looking the same and it really is a lot.

[mike-2ptzero]

only 300 lbs? thats really not that much.

Lets see anyone try to get a B6 A4 1.8t down to 2800 lbs without fully gutting it or cutting body panels off.


Here is a test for you. Get a 300 lbs person to sit in your car and do some runs, then run without that 300 person in your car and see if you feel the difference.


That extra 300 lbs over a 3200 lbs B5 is nearly 10% increase in weight.

Then go with the B6. With the 170hp 1.8t you'll have a car that's reasonably quick and enjoyable.

Contrary to what all the kiddies on here will say, the car is plenty powerful for everyday driving and in the curves it handles much better than a B5 due to its stiffer chassis and improved suspension--stock B6 is equivalent to a B5 sport suspension.

The car isn't fast, but it's not terrible either. Power isn't everything; the handling and the gearing make up for a lot in the fun-to-drive department.

[Dreamert]

I guess I'll have to test drive both to make up my mind.....wish me good luck on this lol finding both models with Sport Package to test drive, not gonna be easy but I'll try.

Thanks for all the inputs !
