- What is up everyone! I just wanted to get this year started off right, so I wanted to get this highly anticipated episode II video posted ASAP. Sorry about the crappy audio throughout the video, I'm really not good with computers so I'm still learning how to do this right. I do not consider myself a professional, I am merely a motorsport enthusiast that loves high power, fast speed and big turbos :)
Just because you see something in this video doesn't mean that it's right, but I try my best to not give any false information. I'm hoping the next video in the series will be a parts video when I get everything in and get the crankshaft back. I plan to include prices for every part shown in the video. It will take some time to get everything back so thanks for your patience. Stay tuned guys, 500whp AAN here we come! - Авто та транспорт
What's up everyone? Just wanted to get this year started off right by uploading episode II of my newest build series. I'm having a lot of fun with it and I have a lot more ideas for future videos with this project. I will hopefully have all the parts soon so I can show you guys everything involved including prices.
It will take some time to get the engine block, cylinder head and crankshaft back from the machine shop so I greatly appreciate your patience. This thing is gonna be a certified ripper when it's done, can't wait!
I love your videos dude. I’m about to get an Audi 90 with a 2.2 turbo I’m gonna be watching your stuff on the daily. Wish you were west coast I’d pay for your time and advice.
By far the most in-depth build guide I've ever seen for these older 5-Cylinder engines! Keep it up! These are so awesome and informative!
I really appreciate that you were very specific and clear on everything. Length of the video is good cause of all the info. No short cut wish you were closer to me I would send you a spare block and let you spruce it up. Keep the great work.
Happy new year mate. Great vid.
Another high quality vid, keep it up man! This budget build series is awesome.
As always, great content. 👍
Bro, excellent video (and series)! I bought my '94 with a built bottom end already, but it's great to know if I ever need to pull it apart I have such a clear, concise, and in-depth guide to follow. These cars are so rare in the US, and so many of the owners are... let's say "distinguished older gentlemen" who often have trouble posting pictures on a forum, never mind filming and uploading videos. Someone who actually knows what they're talking about posting quality ur-S content like this is a welcome change.
Bu
awesome Video lots of details *thumps up*
Great start for the year! I want to do a bottom end build for my AAN in my 4kq, but don't want to tear the car down because I often have to shift focus. Maybe I'll get lucky and find another AAN to build. Thanks for keeping up with good content!
Luv ur videos bro
Great videos brother, I just got a URS4, my third Audi 5cyl and wanted to get in touch with you regarding the upgrades I have plan for it.
Hi! We did have a problem with those manifolds, the welds inside broke and destroyed the turbo
S257SXE is the turbo i bought for mine as well! can't wait to see how it spools
I saw that at the end of your video and I thought to myself how ironic. I have been wanting to try this turbo out and with the opportunity of a new build, I quickly talked the owner into buying one. It's a no brainer, for the money I don't think you can get a better one at this power level. I also have plans to upgrade the oil cooler since the turbo is no longer water cooled.
I'm itching to see what it can do as well, I personally think the newer sxe line can handle the higher 35-40psi of boost without issue as they are designed for diesel engines. In my experience running over 30psi with ball bearings is just a matter of time until failure. It is going to take some time to get everything back for assembly so I may get bored and just slap this s257 on my car and test it out at all different boost levels for a video :)
@quattro4life you’re the man! Can’t thank you enough for this awesomeness. It’s a new year gift for me. My S2 has been built for 5 years and it stopped due to lack of expertise and proper knowledge. But you’re giving so much valuable info. Any other places I can follow you? Insta or facebook?
Would you recommend using the stock coolant return pipe that runs to the left side of the engine with the pipe there despite the small diameter? Just for routing purposes, I have a regular line that I am running but it is much harder to fit.
Just finished the hr. + Vid. So pumped on this practical real time no frills content! Are there any advantages that the 3B has over the AAN or does it all tip in the laters favor when you add in the RS2 manifold and relocating the radiator to the rear (I'm building a Sport quattro replica). Going the 7K route is tempting but would rather stay true to the old school Audi platform. The only reason I ask is I've found a reasonable 200 with a 3B with moderate miles. Thnx again for all the knowledge 💣!
How is the budget build doing its been 2 years im looking to do a build like this . Do u have a parts list?
Hahah. In the beginning I was about to turn this off cuz I thought your voice was really like that
is there something weird with cyl nr3? my aan rod blew on that cylinder last winter and I was only at orginal boost level.
Hey man, on your last vid in the description you listed the GT3071R which I've been thinking about going with. Would you recommend either that one or this Borg Warner S257SXE that you showed in this one. I'm hoping for 400whp setup similar to this one just toned down a little.
I think it all depends on how much you are willing to spend. I like the BW because they are cheap and reliable. For 400whp the S257 would probably be too laggy. The S252 would be a better match for that power level in my opinion but I haven't tried one so I'm basing this solely off of data. The S252 compressor wheel is very close to the gtx71R so it should make similar power.
The GT3071R on my friends car makes around 400whp at 24psi on E85 maxing out the stock AAN. In my experience the car is more fun when you can push a smaller turbo on higher boost versus only being able to push a bigger turbo on lower boost. I'm trying to get an S252sxe for the channel so I can compare it to the 257 so we'll see...
@@quattro4life20vt hay bud I need to get in touch with you regarding vemz what is the price you can get it for coz I can't seem to find a proper listing and it's not available in south africa

hey man, any news on this budget build?
Im waiting for that maxpeeding rods assembly. Im thinking of buying them.
Gonna do simmilar engine build already got engine in peaces.
Very curious myself, they look very identical to the scat rods that I put in my car. I put them on a digital scale to check for weight inconsistently. I was amazed, there was no more than one gram of variation between the five of them. Needless to say I was impressed. I plan to show these findings in an upcoming video. Thanks for watching!
@@quattro4life20vt you got instagram or facebook ? In case i need any tips on engine build.
@@quattro4life20vt I just finished my AAN build with these rods, and i was also amazed with the quality for the price. Now the engine has just run for like 500km on the MTM tune and nothing exploded yet :P but getting ready for the big turbo in the spring time. Also using ARP head and main stud kits. All cylinders bored and sleeved to fit factory pistons, and a reground all the bearing journals on the crank for the 1st oversized bearings. Hopefully should be a reliable ripper soon.
@@matiganek that is really good to hear! I'm sure you won't have an issue. Don't be afraid to post a video and show us your car! You can always put a link to it here in the comment section :)
Definitely gonna be a ripper, thanks for watching and sharing!
Just a question as far as hydraulic lifters go… I’ve had an AAN sitting for years and finally getting around to working on a swap into my coupe.
Some of the lifters are spongy. Is it possible that they’d be fine once it’s running with oil pressure, or is that a dead giveaway they’re toast? Any advice would be greatly appreciated.
Thanks.
Not a bad question, there is a good chance they are fine. The AAN that I installed in this car on the first episode was the same way. Sat for years and all the lifters had that same spongy amount of play when pressed on.
They made a lot of noise on first start up, but after about 5 to 10 mins all of the lifter noise was gone. If I was you I would just go for it! I'm sure you will have similar results :) thanks for watching!
@@quattro4life20vt thanks for the info dude! Great channel by the way!
Whats up Quattro4life, i have a silver 92 S4 second owner 150k miles, only mod is removal of complete exhaust system and replaced with 3" turbo back. So my car started having problems with anytime i would put throttle wide open the car was cutting fuel or dumping boost almost violent. Now im only running at 75 % power and factory boost gauge is stuck at 0.8 regardless of RPM.
Any ideas im thinking tubing running to ecm is kinked or has a hole. Let me know what you think. Also sensor at end of fuel rail is cracked a little can't seem to locate online or what its called. Thanks man big fan would like to hire you to build my car to 500hp.
I would definitely check the vacuum line for the map sensor in the ecu. It is common for the line to pop off at the moisture trap located under a cover on the fire wall just behind the fuel pressure regulator.
The connector at the front of the fuel rail is for the cam sensor. Follow the wires, they should go behind the timing cover to confirm. If your car starts up then you shouldn't have an issue with the cam sensor.
@@quattro4life20vt you could be called the URS4 whisperer, i removed the cover on firewall and what do you know line had fallen off the trap. Any other small tweaks i can make to my car to squeeze a little more power out of it? i have removed complete stock exhaust system 250lbs at least and replaced with turbo back 3" exhaust that i built with exception of pricey down pipe from some company in Cali. i would like to talk about getting on your list to get my car up to 400 - 450 hp. blairheating@yahoo.com Thanks again and hope to hear from you.
@quattro4life hi man,you got a way to get in contact other than youtube?
Doing a timing belt on my urs4 what torque procedure do you use on the crank hub bolt? Thanks.
Best way is to get the locking tool number 2084 and torque it to 250 ft lbs. That's what I do for my engine. You can run it on with an impact gun but it is possible to damage the key way on the sprocket and if that fails then so does the engine. You can get the tool from EFI express if you don't want to take the risk!
@@quattro4life20vt thanks,one more question,do you reuse the crank bolt?also any loctite? Again thanks
@@markroberts9225 yes I reuse mine every time, pretty sure my crank bolt is original. You can throw some blue loctite on the 4 bolts that hold the pulley to the crankshaft sprocket. At 250 ft lbs of torque I don't think it is necessary to use it on the crank bolt. But if it makes you sleep better at night then I'd say go for it!
Any chance you could post a list of parts recommended or required to make 500whp?
As far as the engine internals go the factory pistons are forged and can easily support 600whp. The factory rods limit you to 400whp on a stock AAN. Swap the rods out and throw in some ARP headstuds making it a bulletproof budget setup at 500whp in my opinion...
I will be continuing this series with episode 3 and that will most likely be a full parts video once everything comes in so stay tuned!
@@quattro4life20vt what about main caps and main cap hardware? If I go arp will I need to line hone the block? Super excited for future videos, I'm working my way through all you existing videos, they're awesome!
@@carstuff3791 main caps are good, factory main studs can handle 500 but I have never pushed them that far. If your going through all the effort then obviously I would go arp head and main studs just like I did. And yes it is highly recommended to line hone for arp mains.
What forum do you use? Quattroworld?
I have used quattroworld to sell parts before but that was years ago. All my friends want me to get social media but I have never been into it so I doubt that will ever happen.
A quick question. I want to run my stock AAN (REVO 303) with that stainless manifold but can i run it without the MAF sensor without any issues or do i need it?
The exhaust manifold is not going to effect the MAF sensor so it doesn't matter. The MAF works fine on lower power levels but when you run high boost/power it is recommended to delete it and run speed density.
Yeah but the manifold places the turbo in an akward position to run with the MAF. Do i need to do any mods to run with just speed denisty or can the stock MAP sensor do that?
@@marcusholmare Marc at EFI express can set you up with speed density tune on the stock motronic ecu if your interested. Either way, if your going to run the manifold you have to delete the airbox and turbo inlet pipe. You have to make a new intake that is similar in length to the stock turbo inlet pipe, this will ensure that the MAF will function correctly. You will need to modify the turbo outlet pipe as well since the turbo has moved. All of this information can be found in my Audi UrS6 build vlog part I ;)
@@quattro4life20vt Thanks dude, keep the vids coming, great work! :)
@@marcusholmare you will have to completely remake the oil and coolant lines as well so I recommend doing the manifold when your ready for a bigger turbo. Thanks for watching friend!
Could you link the manifold please?

@@quattro4life20vt how you gonna fit the BorgWarner supercore into this? This manifold has the K26 flange, right? Or you choose some other fabrication route?
@@audiemblems that is correct, I am going to modify the manifold by welding a t3 flange over the k24/26 flange just like I did on my friends UrS6 with the gt3071r. I plan to make a whole episode on just building the turbo kit and installing it on the car. Stay tuned!
@@quattro4life20vt definitely will stay tuned! Also what type of timing you use for VEMS? 60-2 on flywheel or hall sensors? I saw people use rear main seal of VW T5 or Lupo which has 60-2 crankshaft timing sensor in it.

Yes of course, the land speed car has always been my inspiration! Jeff is in possession of my cylinder head as we speak, so we have been in frequent contact as of late. What a cool dude, I am probably his biggest fan haha.
He told me just yesterday he will be installing a custom ratio 01E 6-speed dog box built by a company in Canada called "drivesport". First gear will be a 2.80 ratio, I put the info into a transmission simulation app and at his 10.3k rev limit he should hit 60+mph in first gear :) top end killer!
