Need some insight/input for my stage 3 build

[Auditude437]

Hello everyone,

I recently purchased a '21 TTRS and am prepping it for stage 3 soon. Below are the mods that I already purchased but wasn't sure if I needed anything else. Hoping someone could chime in and see if I'm missing anything. Will I need a clutch +flywheel kit? Any insight/input will be really appreciated. Thank you!!


-TTE700
-Iroz LPFP (**pending purchase**)
-Unitronic Downpipe w/ Midpipes
-Unitronic 4" Turbo Inlet Elbow
-Unitronic Carbon Fiber Intake System, 4"
-Unitronic Intercooler Upgrade Kit
-Unitronic Wastegate Line Upgrade Kit
-Unitronic MPI Upgrade Kit
-Unitronic 2.5TFSI EVO Spark Plug Set
-Unitronic P3 V3 OB2 Gauge
-Unitronic stage 3 ECU & TCU tune (**pending purchase**)

Not sure if you have an upgraded dogbone/mounts. You won’t need to mess with the tranny for a TTE700 though.

ECE Dogbone Mount, and Motor/Trans Mounts (034 or BFI) I have had ECE dog for a while with stock mounts and they are fried (6k miles on stock mounts on stage 3), suspension? and Probably want a better wheel/tire combo to get traction with an 18" possible a 19" on a ttrs...

Oh and definitely want a DSG catch can a must if launching at all or even 1st gear rolls with stage 3. Engine catch can is always a good thing to add as well. Charge pipes can be added as well. various companies, I have red Forge boost hose kit BNIB i'd let go for cheap if interested. Some use upgraded coil packs as well.

If your going built motor I would definitely do flywheel upgrade from DCT or Iroz but clutches are not needed for 700. If you're planning full frame in future then yes, if not then no. Feel free to PM as well, lot of information in a private uni chat group too. I am in process of going from stage 3 stock motor to a built motor setup, and tried to do a lot of research.

Wow, really appreciate the in-depth info. I will definitely keep this in mind and will PM if I have any further questions. Thank you very much!!

Build the motor. So much more expensive to have it fail and then build.

Yeah a lot of people have been telling me to. I'm considering it but I'm curious what the performance difference is between the stock motor tuning file and built motor tuning file.

I believe on the TTE700 its like 70ish WTQ and 30ish WHP, but yes I would strongly consider building motor too, much cheaper to do in the beginning than to repair in the end. If you go that route may want to consider tte777 too very similar spool with even more power on top.

Build the motor! If you go on stock block with E85, it is a disaster waiting to happen. I never launched my car, I mostly daily drove, I changed the oil frequently, and I seldom went WOT, yet I bent a rod on a low torque file after 7,500 miles and it not only cost me money, but 14 months without my car.

If you can afford all those parts, you can afford to build the motor.

Here's another example of someone with actual experience.
I've been telling people from the very beginning that this is the right way to do it (see it on previous threads), but it's only until just recently people started echoing my sentiments.
Better safe than sorry!

What stage? OTS tune?

Same specs as OP.

Stage 3 E85 and stock block then?

Wow, my goodness. Sorry to hear that. I wasn't planning to drive that hard either but I think your comment alone will lead me to build the motor. Thanks for sharing that. Wow.

[Nartard]

Agreed on building the motor, planned event vs. a surprise event. Might also want an Ethanol Content Analyzer if it isn't part of Uni's P3 setup. And 034 Street mounts for the trans and engine.

Sorry forgot to also ask. Now that you're on a built block, are you still staying on the stock block file or are you on the built block file now?

I don't know if there is much of a point in doing a hybrid turbo on a stock block with e85 and conservative tuning. You can't really push the engine much harder than stage 2 e85. Some people do, but as mentioned throughout this thread, it's a disaster waiting to happen.

Unitronic Built block, E85, TTE 700, upgraded fuel pump file.

The block was sleeved and the bottom end built by Iroz. They took about 12 months. Car was dissesembled, reassembled and tested by TCR. Josh at TCR was not just fast, but thorough. I can’t thank him enough for the job he did.

I need to get upgraded motor/tranny mounts. Way too much power for the stock ones.

Did the block survive or only bent a rod and scuffed a cylinder? I am stage 3 E85 stock motor but only 1000 miles on car last year. Might get that this year build is in the future plans.

[HWCN]

Block survived. It actually ran fine and I didn’t notice it until I parked the car running and saw the blue smoke. As I stated, I never launched my car and mostly daily drove. It only made it 7,500 miles.

I ran Unitronic Stage3 E85 file with tte700 for around 10K miles with no issues but the stories of motor failures eventually got to me so I put a built motor in it with Iroz fuel pump and 4 bar sensors. I mostly just run 93 since I don't drag race the car and its been very reliable so far.

Hmmm, build motor only to most NOT run E85? Color me confused? Take advantage of/Use those parts that you paid $$$ for!

I was of the mind to eventually go to full Stage 3 Uni 710H stock block/motor E85, 93 oct for winter, but have probably decided against just hearing failures even with just DD use/driving.

I'll probably just stick with Stage 2 E85/93 oct winter since IMO, ultimate DD is where RS3 shines. Unless I fall into a pile of money & can justify building motor...ha!

I'm into keeping this car around for a long time and where I live pump gas file is plenty fast. Don't get me wrong, I will run E85 here and there but the TTE700 on pump gas is the ultimate daily driver and is very reliable. The built motor is just insurance.

[bucolic]

How much HP do you gain going built block TTE700 93 oct vs Stage 2 E85? Doesn't seem worth it for the money you paid IMO... Maybe I'm missing something though.

My main reason for going TTE700 was to get stage 2 E85 power on 93oct but be able to run E85 when I want to. I bought the turbo used with low miles and ran it mostly on E85 for the first year. Low 10's at 138-139. It was plenty of power for me but I worried about the motor being stock. A forum member with a freshly Iroz built motor was parting out and looking to trade his built motor plus cash for a stock one so he could trade his car in. His motor only had 3500 miles on it since the build and the compression and leak down looked perfect so I jumped on it. It cost me half what it would have cost to build mine so for me it was worth it. As for power, on pump gas it runs 10.5 at 135 which is plenty for me as a daily driver. I will put E85 in soon to feel the extra gains but it should be high 9's/low10's in low to mid 140's. For the money I have in it that is all I need and if time goes by and I want more I can just upgrade the turbo but at that point you start looking at new clutch packs and that's where it starts to really add up. If unitronic ever comes through with the flex fuel it will be a perfect no hassle daily setup that will walk nearly anything you come across, not that a stage 2 on E85 doesn't but that extra 10mph in the quarter puts it in a whole new level. Worth it? For me yes, reliability is key, power is second so I think I nailed both with this one.

[Auditude437]

If I have an Iroz LPFP and fuel line upgrade, will I be able to safely run E85 all the time without any issues? How about over time? The car is a weekend car and it'll stay in the garage a majority of the time. I'm concerned what it will do when the E is just sitting in my gas tank. I'm in socal so there's plenty of E85 fuel pumps around here but was concerned since I value longevity/reliability as well and there's only 91 pump gas around here. There aren't many performance numbers for stage 3 TTE700 on 91 pump gas either.

If I were you I would run the tte700 on pump and splash 3 gallons of e85 in it. Its safe, its faster than stage 2 E85 and the motor and drivetrain will last a long time as a daily.

[Auditude437]

Sounds good, will keep this in mind. Thank you!
