A lot of a Stage 3 S4s with tips holding up to the power as a FYI. Being able to burn most cars on the road in your grocery getter is always a plus.

We built a E85 powered Stage 3- avant (full stage 3 fueling will blow apart the torque converter) the car had a IPT torque converter, and STILL the tip didnt know what to do with the power, the car was very quick but the transmission used to hang up not knowing what to do with the power. TIP FTL

It is a terrible mix...all that power and the stock tip, but like I said there quite a few guys in the Audi tuning scene running Stage 3 fueling at a little lower boost usually than 6 speeds and seem to be holding up alright. The new thing now, I guess tuners have helped the problem a little bit by tuning the car so that torque is dropped a little bit right before trans shifts.

Here is a thread with multiple examples... http://www.audizine.com/forum/showth...&highlight=tip

Hey, guys, modding question. Can I fit a 6 speed gearbox in my car?

Yes, we've done that swap on numerous occasions. Though it requires a lot of parts and work. We're currently doing this swap on a RS6 turbo'd S4, guy went through an IPT fully built transmission and has had it lol..

Parts:
Transmission
Driveshaft
Rear Differential
Front Axles
Got to run a clutch line to the brake booster from the pedals and then to the master slave on tranny
Pedal set
Got to recode the ecu
Cluster recode to 6spd (tips are 5 with different gearing)
Need a different shifter surround
You need a shifter linkage + shifter
You need a different flywheel
You need a clutch

I may be forgetting a thing or two. But yeeah its a lot of work and money involved, you essentially need to know what you're doing to do this swap.

No point on spending money on the injectors / maf with a tip, because you can push a 3- to the limits of the transmission way too easily.

So, how much would a 6 speed gearbox cost with all the little doo-dahs?

You just need to chip the trans as well. Aparently a GIAC chip allows the tranny to stand up to about 375awhp or so. The problem with the stock tune is that the trans doesn't know what the fuck to do and hunts gears. It also can't shift quickly enough (normal shift time for a tip is 1 second) so the fluid heats up too much. Also because it takes some time to shift the clutch packs slip and obviously get worn more quickly. The other problem is the TC of course.

How much would a swap like that be? From what I hear its around 6K or so.

I'm sure you could get parts from local junk yards but if you don't know how to do it yourself you are going to end up paying ALOT of money for labor.

I am surprised even with some tuning that the trans and TC trans can still hold that much power and boost. I know the guys at VAST have done amazing things with their customers Auto trans getting them to hold as much power as the K04s can put out on race fuel with some finicky tuning. Obviously they didn't run it like that for very long but that trans is still holding to date on K04s with street tune at 19lbs i believe. So, it can be done...which is why I linked to that thread with multiple instances of Stage 3 Autos and only one of them running fully built trans and some of them with 20k miles on them at that kind of power w/ only the Trans chip and higher stall TC.

My 300zxTT started off as an auto so I know all about power + autos but I didn't even mess with it. As soon as it was done I just did the manual swap. Little easier in that car than the S4.

^Well you gotta figure a 2WD would be easier to work with than AWD. I think most cars are easier to work on than Audi's, they put the engine way too far up front to increase leg room.

Yeah, the S4 is a pain to work on but I would still say overall the 300zx was much worse as far as anything concerning the engine. If I do try and compare the 2 I would say anything engine bay is more of a pain on the 300zx and anything else is more of a pain on the Audi, the latter is to be expected. Believe it or not, Audi did a good job with the limited space engineering ways for a mechanic to reach much of the stuff with removing 80 gagillion things out of the way first. Nissan failed to do this with the Z, they just threw it together and if something failed you have to figure out the best route to access it. Regardless, both cars are known for being extremely frustrating to work on along with some others that I have heard of anyways, without going exotic of course.

But yes, I am anxious to move on to a much simpler car in my future, though 02ish 911 Turbo is at the top of my "next car" list which would be doing the completely opposite of simplifying.

Labor wouldn't be as much as you may think. Check us out and feel free to contact, (easier by email, we get pretty packed on the phone a lot of the time)

^You know the B5 S4 engine into A4 swap sounds entirely too enticing

[LeVeL]

how reliable are stage III cars? Id be a little wary of daily driving something like that. I know more than enough people that have upgraded their cars and something is always broken

SSP eh? You guys got quite a backing on the Audi forums around. Keep up the good work over there.

K04s are far superior than K03s as far as reliability is concerned. As long as you have all the supporting mods, clutch, fueling, etc and don't track it constantly I would say it is just as reliable if not more reliable than stock simply because of the K04s, but things always go wrong whether it be stock or stage III.

I thought Stage III was a GT turbo not a K04.

Stage III is k04. GT28 is Stage Badass.

Well the hot thing discussed right now on the scene right now is KKK Eliminators by ATP, which are costing $4k for a set. I am guessing it is only a matter of time before GT kits or eliminators or whatever have you completely replace the K04s in the market. Right now, going GT is just a bit more expensive than going K04s but I look for the price to drive down and be a lot more competitive in the near future. GT kits have gone from $10k builds to a $4k set of bolt on GT turbos within the past year so I look for that pattern to continue.

Very nice car! Don't worry so much about shifting; you've got plenty of torque...just put it in 3rd and drive!

Thanks.

I wish you guys got to experience a GT S4. One of the shop cars used to be a twin GT28 setup, that car had a kick. I pressed it in 3rd and into 4th, in the stretch of an 1/8th mile I went from local speed limit of 40 to 120
Its quite a thrill.
