B5 A4 01E Swap Info Thread

[lepermessiah]

@Nollywood no spacer was not used, as it's not compatible with 1.8T block

@spindoctor I will try to get flywheel somewhere from Europe and if I have no luck, I will try to get something from US :/

but if I understand it right, I can't put 228mm clutch on 240mm flywheel, so I think that I need to look for thinner 228mm flywheel or thinner release bearing. I don't have money to buy whole 240mm kit for $1000 or more

EDIT: looks like ALL clutch sets for B5 have same release bearing, but there are 2 different release forks, so I will try to look for number of my fork and if it's the taller one, I will order the other and if it doesn't help, I will order RA4 (my stock flywheel is single mass)

INFO: ClutchMasters kit (for max. 420Nm/310PS as I requested) with lightweight flywheel costs 1440€ in EU (over $1900 USD !!) through official dealer - that's too much, still hoping for that release fork

[Iapetos]

Good Info!

[lepermessiah]

so I've ordered RA4 flywheel with RS4 clutch kit, I hope that it will work

my 228mm clutch looks little bit burnt but pressure plate is totally dead - after 5 miles :D

[lepermessiah]

OK guys, problem solved. RA4 with RS4 clutch works good, but I need to rework exhaust as it's too thick (2.75 pipe) and has no room beside the gearbox so it's making weird noise and whole car vibrates

[Crispy222]

one problem solved, another shows up.

[chris164935]

So, if I'm reading this correctly, the stock-sized clutch/flywheel setup from a 1.8t will not work with an 01E? My current set up is a Clutchmasters FX725 twin-disc with steel flywheel.

[lepermessiah]

yes, stock flywheel is too thick for this swap. it's at least 2 times thicker than custom RA4 flywheel

[M-Hood]

yes, stock flywheel is too thick for this swap. it's at least 2 times thicker than custom RA4 flywheel

It is thinner because it is designed to be used with a 240mm LUK pressure plate which is way taller then the stock Sach pressure plate.

So, if I'm reading this correctly, the stock-sized clutch/flywheel setup from a 1.8t will not work with an 01E? My current set up is a Clutchmasters FX725 twin-disc with steel flywheel.

It will work as long as the stack height of the flywheel/pressure plate are not too tall, if it is too tall the top of the pressure plate will hit the back of the bell housing. You shouldn't have a problem with the FX725 fitting since the stack height is not even as tall as the stock clutch/flywheel, which is why it uses a taller TB. A CM 240mm clutch/flywheel will fit with the 01E which means a CM 228mm will also fit since it tends to be slightly shorter then the CM 240mm setup. Even the FX850 fits, Gunnar is running the FX850 twin with a 01E on his 1.8t.

[Schrubbe8210]

So just for clarification, as a guy who has literally all the supporting parts sitting in his garage, and is picking up the 01e this weekend, the stock 228mm clutch/flywheel/TOB setup will not work due to it being too thick. Neither will mix and matched sets of OEM/aftermarket parts. However, any complete aftermarket clutchmasters clutch/flywheel/TOB set (either 228 or 240mm) for a 1.8t will play nice with the 01e? All this back and forth with lepermessiah confused me.

[ricekikr]

What brakes are needed for a pre-facelift 1.8tqm?

Will i also need rear axles and uprights?

If you're following this parts list:

96-00 A4 1.8t
S4 Axles
S4 Uprights & Hubs
S4 ABS Sensor

You would need S4 brakes or something aftermarket (Brembo/Stop Tech) with adaptors.

Rear axles:

S4 Rear Diff
Direct bolt in, requires use of S4 rear axles or swapping of the diff flanges
Tiptronic A4 Diff
Direct bolt in, uses stock A4 axles

[S4NIK8]

Anyone with a more "medium" (2860) size turbo do this swap? My 01A is on it's way out after 250k and I have an 01E sitting in my garage.

[redline380]

I really think the sweet spot for a medium sized turbo is a 5 cylinder 01e 5 speed, but I have no personal experience to back this thought up

[S4NIK8]

Well I guess I'll find out; probably swap it in next week depending on my schedule.

My thoughts exactly!!! too much back and forth I have everything sitting in my garage ( trans, subframe, axles, driveshaft, rear diff, front uprights) I just want to know what else i Need and what clutch/ flywheel i need

[pee quu]

btw my 1.8t has a k04 , not my daily so really not overly concerned with all this mpg and gear rations. I just want to put this stuff to use since the trans was rebulit about 20k ago and is not going to the project I originaly got it for

[chris164935]

Can anyone shed some more light on the differences between the early style and late style 01E transmissions from the B5 S4s? I recently purchased an 01E but the seller does not remember which MY it came from. I plan on purchasing all of JHM's shifter stuff, so, basically, would I just need these:
Gear Shift Lever Base
Selector Rod Clamp
And the 2 shifter rods? Also, I'm guessing that if I used the above parts, I would need the late model JHM stuff?
The car itself is a 2001 A4 5-speed 1.8t.

Pretty sure when it comes to which JHM shifter you need to order it depends on which base you are going to be using in the car.

This is stated on the JHM web site.

If you have a pre 2000 S4/A6/Allroad or a pre 1999.5 A4 and your shifter looks like this (metal base) please do the following.



-For Early pre 2000 S4/A6/Allroad - select the "OEM Base for Pre 2000 non-US:" option at the bottom of the order page for STS-B5S4E.

- For Early Pre 1999.5 A4 w pushdown reverse - you must order the STS-B5A4E shifter that upgrades you to NON push down reverse like the newer 99.5 up A4.



Doing so will upgrade you to the newer version and upgraded plastic base thus allowing you to put a JHM "solid" short throw shifter in your car.

Notice the base is metal (old style) instead of plastic (new style).

So it should be the late shifter you need if you are getting the plastic OEM S4 base.

[S4NIK8]

To add to this, there are no clearance issues with a spec stage 3 228mm clutch and awe flywheel. Haven't driven the car much since finishing the swap so no real impressions on the gearing differences.

The cross rod on the trans is also different.

[ricekikr]

For the reverse lights, you just need to clip the old wires and solder in about 12" of wire with the 2-pin connector. You can use any 2-pin connector i.e. N75, fuel injectors, etc.

Are there different kinds of reverse switches? Mine looks like it has round corners. No way will an n75/injector plug fit.

[ricekikr]

Just finshed my swap.

A4 abs sensor works just fine. No codes. Just spaced it out using a thick washer.

A4 neuspeed shifter works but without reverse lockout. Guessing game if in reverse or first. It is centered. 01e shifter box + a4 neuspeed.

[demonmk2]

I wonder if anyone on the board has used the jhm carbon synchro kit
and how well it holds up to the added power.

[GoremanX]

Confused about why the S4 uprights are required at all... on my 2001 A4 1.8T, the wheel hub end of the front axles are identical between A4 and S4. Both 100mm and 108mm axles will fit in either of those wheel hubs. And track width is close enough as makes no real difference as far as axle length is concerned. I'm currently swapping in an 01E and purchased the S4 uprights based on the info in this thread, only to find that I didn't need them.

I understand the need for 108mm vs 100mm axles (since the transmission output hubs are different), but I don't get why the uprights need to change.

The a4 1.8t quattro m/t have smaller hub bearings than the s4. There are some a4 models (forget which) that have the same hub bearing size as the s4.

Must be mine then, because my 2001 A4 with AWM 1.8T m/t has the exact same bearings as the ones in the S4 uprights I purchased.

Pretty handy, means I don't have to waste money buying S4 calipers. Kinda wish I hadn't wasted the money on the uprights, though...

01 A4 1.8T got the B5 V6 82mm wheel bearings as standard.

You cannot use S4 front brakes on A4 uprights as the caliper mounting ears are too close together, hence necessitating S4 uprights

Everything graciously mispelled by Android

err, yeah. I know. That's what I said. "I don't need to buy S4 calipers because I'm not going to use the S4 uprights that I bought for nothing" (paraphrased). This means I can re-use my A4 uprights and keep my existing A4 calipers, A8 brackets and A8 312mm slotted rotors. Money saved. *cha ching!*

edit: in fact, wouldn't that be the ideal thing for anyone to do? Acquire the A4 V6 or A4 AWM uprights if those aren't already on the car? I bet there's a ton more of those available to buy than S4 uprights, and possibly for less money. That way there's never any need to spend money on S4 brakes at all when converting to a 6-speed. Also, could retain the existing ABS sensors. They wouldn't even need to come out. Even more money saved. Probably no alignment needed afterward either. Yet MORE money saved!

*cha ching!* *cha ching!* *cha ching!*

[M-Hood]

Don't really have to do any of that stuff, don't even have to buy new front axles since you can just swap the flanges off the rear diff and put them on the 01E to use your stock A4 01A front axles.

[ray4624]

so that that point, you would just need transmission, driveshaft and rear dif?

[M-Hood]

Plus the shifter box, S4 6 speed shifter and linkages. Then there is dealing with the transmission brackets/mounts, I used a custom bracket to mount the 01E to my stock 1.8t manual sub frame on the driver side and the stock 01E passenger side transmission bracket. Other option for the 1.8t owners is to switch to the other subframe which is used in the 2.8/2.8 and 1.8t Auto.

[ray4624]

i remember seeing that bracket. It looked like something i could have fabbed up. Easier then swapping subframes.
I more or less dont want to swap uprights and lose my bbk etc.

Dont know if its worth it at all. When i inevitably blow apart my 01a maybe ill just source another used one.

[GoremanX]

Wait... shifter box? I can't re-use my 01A shifter box with an 01E?

[PZ.]

I used the stock clutch setup without issues on my swap. I swapped from a V6/Tip combo to the 1.8T/01E on my 01 B5. I will need to upgrade the clutch as I have more traction than clutch and even a 2k launch results in slippage. I've got a RS4 PP and Kevlar clutch sitting in the garage from when I picked up the trans, but I don't know if I want to go 240mm on the flywheel of keep the stock 228.

This is not true. The S4 uprights have different brake caliper mounting points. The AWM uprights just use a larger bearing but still have the smaller A4 brake mounting points.

[GoremanX]

Plus the shifter box...

This is incorrect. The shifter box is the same between 01A and 01E. Even the bellows for the rods works fine. The shifter base needs changing. but not the box.

[M-Hood]

When I say box I meant the actual base.

[GoremanX]

When does the reverse light switch actually close? When the shifter is moved all the way to the left (past the 1/2 gate), or when the shifter is physically engaged into reverse? My reverse lights aren't working, and so far I've narrowed it down to the reverse switch itself. I'm wondering if maybe I don't have the shifter adjusted properly so it isn't pushing the rod far enough to close the switch.

If you plan on making power later on go 240mm and save yourself some headache later on. That being said the 228mm can hold it down with the right clutch but for the most part the price on any decant clutch and fw setup will not be much different 228 vs 240. I have a 240mm 6 puck not great for DD but makes for a fun weekend worrier.

to bring back a somewhat dead thread, who all has done a b6 a4 1.8t 6 speed swap into a b5 a4? is it worth it or are there more hoops to jump through than doing an 01e trans? i am building a holset powered 1.8t and my end power goal is going to be higher than my 01a will like (at least i hope i make too much power for it) and after reading and reading i am curious as to why that 6 speed is less prefered to the 01e... its made for a 1.8t and has a final drive similar to what our cars already have. but i have never seen how they are mounted or what electronics it might have that ours dont. if anyone has any info on why i should do the 01e swap instead of the b6 6 speed i would greatly appreciate it!
