@@PBGarage Ahhhh! There’s the difference! Although I haven’t heard much negative about the XSPower KO4s. I know they use a VSR sort rig for balancing and a VSR balancer can easily cost $30-$50K vs say a basic Heins TC3 balancer which you can get for a few thousand. So, there’s that. My understanding is that XS uses genuine BW turbos to start with. I plan on getting the RS6 hybrids myself.
My Allroad 6mt made 325hp 345tq at 4500ft on stage 1 tune by Blake data was taken with using an accelerometer iPhone, only modification were heat wrap on exhaust J manifolds to turbos, and heat blankets on the header pipes at the engine block, stock cat's and OEM tail pipes.... Water injection is definitely the way to go for extra power without octane, I need to complete my build, I installed the injection right under the throttle plate in the manifold, can't wait to hook it up completely ....
Are those numbers calculated as wheel or crank? Likely crank as they seem representative for a 2.7 stage 1. Before I embarked on the stage 3 build my s4 had a stage 1 tune and it was a ton of fun. My winter / summer beater daily car is a B6 Avant 1.8t but I would love for it to be a 2.7t stage 1 like your allroad. Perfect amount of power (can always use more i suppose haha)
@@PBGarage Stage 1 is useful in many respects, the stock turbo's are less than desirable, K04's or SRM Turbos under a stage 1 or 2 tune is really a perfect fit for utility, otherwise your just racing.... lol
Funny, I lived down the street from this place from 13-17. Had a red URS4 back then. Stumbled on your channel and the scenery looked familiar. There was a yellow B5 S4 Avant on my neighborhood down the street from our old house. Great project, watching the videos as I get my house keeping on! What happened to the 20vt B3?
Thanks for the comment! The B3 ended up being stripped for parts and the shell sent to the scrapper. A main bearing in the engine failed and locked the engine up, and it was at the point where the body was getting pretty rusty / my priorities were changing (I say that after just completely overhauling a B5 haha). But at the time it made sense to move on from the car into something else (~2011). I picked up a E34 BMW, had two kids and got married, then several years went by before I scored on the B5S4. I'd love another B3 or even B4 for nostalgic reasons, but practically it doesn't fit in my line-up right now. Plus the B5 is such a nice chassis compared to the B3.
@@PBGarage the B5 is a great chassis, I drove a few B5 S4’s and some ko4 A4’s. Fun cars. The B5 maintenance wise always put me off. Just seemed like it needed too much $ all the time. But then what old Audi doesn’t ? Saying this as I build my UrS4
Haha ya tell me about it. When my 90 kicked the can I thought it’s time to get a reliable daily. Next cars after that were 88 BMW, 1990 Audi coupe, B5A4, mazdaspeed3, B6A4 Avant automatic, B6A4 Avant manual, B5S4… obviously allll reliable cars 😂
I’d love another B5 as a daily though, a 2.8 B5 in mint condition came up for sale last year but he was asking $10k, plus the b6 Avant I use now is pretty handy.
Thank you! I did some digging around for info on the auto and Stage 3, and it seems to be okay but I wouldn't quote me on that. All the yes or no opinions are anecdotal, so I can't say for sure the auto will hold up to a certain hp/tq number. If you do try it out please let us know how it goes!
Still running my Ming Blue Avant in factory spec (engine & tune) and very happy. Now covered 295k miles with no major issues. I did replace the worn out suspension with an H&R coilover kit which transformed the handling, however, recently replaced all the suspension bushes with Powerflex street bushes and the ride is now a little to firm. Thought the car does handle superbly when pressing on. For me the weakest aspect of the B5 S4 is the gear change (both feel and operation) which doesn't like to be hurried. A JHM short shifter kit did improve it considerably, but for me it is still the one aspect of the car that disappoints. Does anyone have any remedies for this?
Yes suspension upgrades certainly make a huge difference. I kept my suspension bushing stock but made aluminum subframe bushings. The car feels very planted and handles well but does feel a bit stiff on rough roads. As far as shifter upgrades, mine is completely stock and sloppy. If I do anything it will to just replace the worn components with stock pieces. I’m not fussed about short throws or anything like that. Aside from JHM there aren’t many aftermarket options.
has the other builds been abandoned? I was really hoping to see all the builds. I am wanting to do a swap into my b7 audi and was hoping i would get some valuable information from them. The videos that have been put together have been wonderful and would love to see some more!
Over 450 whp with k04s takes E85. With the 94+boostane we were expecting to be above 400 though. I compared my log vs a WMI log for IAT and there is a 25+ degree C difference, so that will help tremendously. That combined with E40 and I will be guaranteed to get speeding tickets everywhere I go!
@@PBGarage It’s good power and lots of fun for sure. This is a ‘Me’ problem. I just had that 450 number stuck in my head for some reason as you did all that work.
@@PBGarage Is the 2.7tt engine can pull higher max power like 7000-7500 rpm with these turbos , or with the stock k03 ? Or it needs different cams or heads ? I was thinking they rev higher, mainly with that amount of power. thanks to share!
@@simontrepanier7320 I think the limit isn't the rpm/heads/cams, but the size of the turbos, even the K04s are still small for making power at high rpm.
Honestly that's not terrible. I know that thing moves! I have a B5 A4 1.8T with all the "stage 3" stuff plus methanol injection. I'm around 250ish and just need the time to put my gt28 on and shooting for the numbers you just got... 350-375. Definitely set up that methanol! On a 90°F day driving down the highway (75mph) IAT sit about 105° but when I get on it and the meth kicks in they drop to between 60 & 70°! I did all the tuning so I know there is definitely power left in it as I'm by no means a tuner but it really woke up! Pre meth I'd go from 105 to 150 IAT in 3rd gear alone! Now I never get close!
Wow good to know about the meth results!!! I’ll install that kit this winter while the car is stored for sure then. How’s the power band on a stage 3 1.8t? Do you find it peaky if you know what I mean?
@@PBGarage the engine has 190,000+ miles so below 2000rpm there essentially no torque at all. But it's getting rebuilt here in a month or so. Other than that it pulls strong, falls off a bit right about 6K but for it definitely surprises a lot of people!
Doing great overall, couple little issues but up to about 10k km since the rebuild. The weather here just got nice so I took it out of storage a couple weeks ago. Running on E40 since last June. Trying to coordinate a dyno session with my tuner for this week or next to see where it stands compared to the 94 octane tune. No other upgrades planned at the moment. Just plan to continue driving and enjoying it while I work on my other projects (B6 Avant and BMW E34).
@@PBGarage nicee man! I promised my best friend I'd become a track driving in an audi, thinking of choosing the a4/s4 stage4. I've been looking online but can't get any numbers about hp, torque or anything other to indicate how fast it would be
Sounds fun!! The b5 chassis will make a great race car. Not sure what makes it a stage 4, though? For racing, my opinion is to keep it simple and reliable. Tons of power accelerates wear and tear on everything, adds a lot of heat, might make it difficult to drive “right” (follow the correct race line)… it could lead to a lot of headaches. A stock engine with a simple tune might be a better choice for the track, with some heat management added (better intercoolers, brake cooling, oil coolers etc) Disclaimer: I’ve never raced an S4 on a track so the above is just my opinion!
Thank you for your videos. They are greatly appreciated. I'm building a stage 3 allroad and very happy to see 380hp/400tq! Cheers
You’re very welcome and I’m glad you enjoy them! Good luck with your build 👍🏻👍🏻
Nice job on the build! I am at stage 2 with my B5 S4 Avant.
Want to take it to stage 3 someday. I am very close. Keep the videos coming.
I’m kind of wondering if stage III is worth it when my stage II/+ rips pretty well and is so reliable at 17-18 PSI.
Tyler is the GOAT
You got rid of the XS Power KO4’s?
Those are going on a different build.
@@PBGarage So they’re still holding up? Good to know!
The BW K04s are holding up! The XSPower haven’t been run just yet.

I need to get mine done. That thing sounds great!

In your description it shows JHR 4:1 shims is that for the center diff?
Correct the center diff has the 4:1 shims.
Nice! I bet that make the car handle better. Can’t wait to do that and put an lsd on.
How much boost and was it holding on all 3 runs? Also what version of intercoolers?
Peak at about 21-22 and tapers 1 or 2 from that. I believe I’m on V3 of the intercoolers
Nice man. What HP is your goal?
Whatever Blake and Sean put down + 1. 🤣
Actually I have 400 whp stuck in my mind for some reason so I’d really like to hit that.
