What clutch to use with 500+hp 99' 2.8L tranny?

[A4 Meets 27t]

Im swapping out the 2.8L and putting in the 2.7t with RS6 turbos. Should have around 500hp with the E85 tune I'm getting. What clutch will hold up? I checked out SB site and the stage 5 is for 1.8t, will it fit the 2.8L? Thanks in advance.

[zrowcool]

nope 1.8t clutch wont fit the 2.7t. needs a 2.7t clutch. i would look into a vast performance clutch personally. IMO you need to do more research before you undertake a swap like that. A lot of work small details involved so read up a lot and plan it out so it goes smoother. just my 2 lincolns

[A4 Meets 27t]

The 5spd from a 2.8L will fit the 2.7t motor SSP tuning has done it. The 18t will not however.

[317ssayzarc]

The B5 01A transmissions are all interchangeable... Trust me, I have a 2.8 trans on my 1.8T now and it went on the very same way as the 1.8T trans that was in it for a while did...

[A4 Meets 27t]

My question is I see that for the 2.8L SB only has a OFE stage 3 that will hold 430 ft lbs of torque. What other options do I have for the 2.8L.

I know 034 sells a SPEC stage 5 any thoughts on that?

[A4 Meets 27t]

So what your saying 317 is that I can get the SB S5 and Itll be fine?

[317ssayzarc]

You are using a 2.7T flywheel which means you need to use a 2.7T clutch...

[zrowcool]

^^Correct as i stated before but in different words

[Splinter]

isn't the big issue the fact that the 2.8 NA mated with a 5-spd and the 2.7t mated with a 6-spd? surprised no one has mentioned that, and that is why you will need a 2.7t specific clutch...

[zrowcool]

no the issues is the flywheel. you can mount any tranny you want but if your using a 2.7t flywheel then you have to use a 2.7t clutch. same as for 1.8t and 2.8. whatever flywheel is on the engine is the same clutch that has to be used. the trannys all mate up the same and can be switched around

[juggernaut201]

ok ill awnser you flat out if your gunna b lookin at 500 hp ... go with the spec stage 5 forr sure south bend stage 3 while a great clutch wil not hold up as well as the spec slutch will give them a call they can help you out with whatever you need and n e questions

[TMorris]

It can not be in your garage if it isn't done. Good luck if you do go through with it though.

[Siena]

^^^ Lol, you're funny as hell!

Good point though.

[michael66899]

Just to put this out there, when I had my 2.8 I tried using a stock S4 clutch and flywheel and I could not get the tranny on. The bellhousing would hang up on the clutch leaving about a 1/4in. gap. Trust me I tried everything to make it work, finally I put a little paint on the clutch and could see right where it was hanging up. Just something to think about.

nope 1.8t clutch wont fit the 2.7t. needs a 2.7t clutch.

Exactly. if you're swapping a 2.7T into a car, you don't put a 1.8T or a 2.8 Clutch and flywheel on. You put a clutch and flywheel on that belongs on the engine being swapped in.

The 01E 5sp will bolt up to the 2.7T, 2.8 and 1.8T. There isn't a fitment issue aside from the driver's side transmission mount. You don't need to worry about that b/c you already have a V6, so it's the same from the 2.8 to the 2.7T.

South Bend or SPEC will have a full line of clutches and flywheels for the 2.7T, I suggest one of those two

[djwimbo]

you said ssp has done it. do you have proof, cause if you don't, then it means they did not do it. good luck anyway.

Are you talking about the trans or the 2.8L to 2.7T? If you're talking about the trans, then a a trained monkey could do it. The 2.7T swap isn't like landing on the moon, it's a swap.

[mike-2ptzero]

my best friend did that swap to his car and it works like a charm.

Yes SSP did in fact use a 1.8t FWD tranny on a S4 2.7, he posted video of him smoking just the front tires with that setup.



As most people are saying, when you swap motors you have to use the clutch/flywheel setup that is made for the engine being put in because the crank for each engine has a different bolt pattern where the flywheel gets bolted down. This is why you can not bolt a S4 flywheel to a 1.8t or the other way around, simply because the bolt patterns dont match up.

[TMorris]

Why hasn't anyone questioned the E85 "tune" yet? Doesn't E85 hurt performance. It's not like gas is expensive either, its $1.33 here.

No, its higher octane but you need to spray 30-35% more of it since it produces less energy. Others that have tried tuning with it found that their knock sensors no longer work correctly so getting the timing 100% right is much harder and the ecu doesn't pull timing back to even out the cylinders.

Back when gas was $4+/gallon it was cheaper to run E85, but at this point it cost more. So at this point its only better to use it if you are actually trying to make more power are just doing it to produce less polution.

E85 = 105oct. Only difference is that you need 30+% more.
I think there's two people that do E85 tunes for 2.7T's, one being SSP. So far it's been pretty successful.

That's why I got excited when there was a low impedance injector driver released for our cars. If I wanted to (down the road, after a build) I could run 1200+cc injectors and build my own flex fuel car.

well thats easy enough to get around:

just swap a 1.8t crank into the 2.7t. seems like a good idea to me

[mike-2ptzero]

mike, where is the proof? well anyways it was a 1990 coupe quattro gear box in the car you are talking about. mike i would like to ask you a question whenever you have time, ya.

Just send me a PM, Email or hit me up on AIM.


The FWD 1.8t trans is exactly the same as the quattro 1.8t trans, it is not a problem to fit either of the 1.8t or 2.8 trans to a S4 2.7 engine seeing that plenty of people have mounted the 6 speed from the S4 2.7 into a 1.8t block mounted in a A4.

[Siena]

Flywheel bolt patterns that match:

6 bolt pattern, offset with regards to crank - I4
8 bolt pattern, offset with regards to crank - I5, V6, V8 40V exc. RS6
10 bolt pattern, offset with regards to crank - V8 32V, VR5, VR6

The S4 / RS4 flywheel can be used on a regular V6 12 / 30V, but will require the S4 / RS4 engine-to-transmission spacer, 11,2mm thick.

My first foray int tranny swaps was back in 1999 - I ran an RS2-engined B2 Coupe Quattro, and I fitted the S4 6-speed.

Not much info about in those days, so I made a few trial and error procedures.

First, I fitted the S4 6-speed in conjunction with an Ur quattro 10V turbo flywheel / clutch, but the pedal was terrible, the distance between the operating lever / bearing and the clutch cover was too great, was a pig to bleed, and the pedal was as spongy as hell.

Second, I ran the 6-speed tranny with stock S4 flywheel and clutch, but after bolting the engine and tranny together, the engine was locked, and there was still a gap. The thicker flywheel meant the clutch was rubbing against the bell housing.

I ended up fitting the 11,2mm spacer, and that cured all my problems.

Worth noting though, whilst some flywheels may fit different models, the crank firing pin / 60-2 teeth TDC reference may not line up with the crank sender, this however, does not apply to I4 models.

[sean1.8t]

these type of questions and you plan on swapping in a full RS6'd 2.7t motor. im a bit nervous for you my man.

are you doing any of the swap? or are you having a professional swap it for you?

and you realize you can't just swap the motor and ECU and have it run right?

also, are you at least putting rods in the motor? well running RS6's flirt with the motor's power threshold

[A4 Meets 27t]

Yes me and my buddy are doing the swap, hes an audi tech and were using my friends shop to do it in. We have a complete 2.7t motor with engine harness/ecu and all. We have the M box and are running a 2000 A6 motor with the hitachi MAF because of the M box. Will will have to do a few rewiring for the body harness but the tach and speedo will work from the A4. We will be starting to do the swap in the next few weeks, were just getting everything before we start. Were putting a stock 2.7T first, get it all up and running before we do the RS6 turbos and all. Will post pics and all during the swap. When we do the turbos we will be running IE rods/stock pistons, 2.8 heads with redone exhaust supertech valves, probably redo the intake valves while were at it, and still deciding on cams, either 2.7 cams to start with, and maybe later play with the 2.8 cams, their a little more aggresive so we shall see. The swap will take us a weekend, should be nice once were done.

[Das General]

"a weekend" hahahaha.

[A4 Meets 27t]

well start early sat finish sunday night, my buddy can get the motor out in 4 hours, also 3 people will be working on the car

[Siena]

If you plan of fitting RS6 turbos, and given the power you estimate you'll make, I'd put rods into that block, and definitely fit the RS6 turbos before installation.

Why would you want to fit it bone stock, only to pull the motor later, to install turbos??

[Siena]

I doubt it'd all be done in a weekend, but that's just me.

Sometimes, it's not the more people there are that make a job move quicker, but the way the job is approached.

It's possible for one person to do the 2,7 biturbo conversion in 5 days, while 3 could do the same in 7 or more.

[A4 Meets 27t]

Reason why is because we don't have the funds yet to put in everything we want for the rs6 turbos, It will be about 10K in parts alone for everything we want. Will wait for tax season to help out a little in the funds department. Also we just want to get it up and running with no problems before we go rs6 just because we can sort out any problems we have with the stock motor.

[TheWrightAudi.]

if you have this kind of money...
sell your a4, buy an s4 with no probs and then do rs6's lol

[A4 Meets 27t]

There are no problems just figuring out what you need to do the job right. I don't have this kind of money just yet. Labor is free. Turbos will come in the spring. I bought the A4 for $1500, body is mint, engine wouldn't start, bad starter salvage title, car runs with a push start. Bought the 2.7t for 2K, show me a place that I can buy a S4 with 75K miles on it for under $4,000 and Ill buy it.

[B5A4Kevin]

i agree with siena. i say wait untill you can afford to build the engine, then do the swap. its possible to do turbos with just dropping the trans, but you need the heads off for the rods so why not just do it with the engine on a stand? any problems you would have with a k03 fitted 2.7 is the same problems you would have with a rs6 one (aside from programming). it just seems like you would be creating too much work for yourself. either way you do it, good luck to you, and hope to see some "after" pics soon. peace.

[A4 Meets 27t]

I do agree with both of you guys, why wouldn't I just do it all at once. 1. Don't have funds yet. 2. Ive driven a 337 for the last 6 years, its fwd, and to be honest I'm sick of wheel spin and just want an awd for the rest of this winter we have in Chicago, its the worst winter we've had here since I began driving 8yrs ago, lol. The ecu I have is already chipped to a chipped 2.7t will be much faster than my chipped 337, and for driving reasons I want to get used to the awd before I step into a 500hp 2.7t. Pulling the motor in and out is a headache but I have the time and labor is free so I guess that's my choice.

[A4 Meets 27t]

As for clutch reasons, will be going with the VAST S3 hybrid ceramic. Thanks all for the help, did get some very useful information. Have a Happy New Year and will post up once the project is started.
