Hell yeah man, another great video. Not a lot of people like to tell their mod list, and if they do they normally lie. You seem ver legit and honest with everything bro. Great video
I don't see why they need to lie smh.
Why would someone lie in their mods?
I do not see sense
@Carlos Montenegro
@@josevictorcarreonferreyra1501 for them to feel good about themselves maybe....thats the only thing i can think about
Nobody really lies bruh
i never seen a lying one time* except when they put alot money they always lying*
I have basically this same setup but I also run a CTS Turbo front mounted intercooler and ARM charge pipes and that helps also. The intercooler helps mostly with heat soak so you aren't running high intake temps after just a few pulls. I keep everything cool with a Racingline oil cooler tucked under the passenger wheel well. I use the Racingline catch can also and the TIG welded oil pan by ECS. Those combined make for a reliable (long lasting) build. I had my intake manifold replaced and all of the valves cleaned prior to the catch can and while it wasn't bad, there was definitely some carbon build up even after 20K miles.
Changing your exhaust is SOO WORTH it, IF you're willing to go through the headache/$ to make it sound right! I wanted a mature, no-rice growl without drone, that's civil in neighborhoods and a monster when you floor it. Easier said than done.. Found myself buying 3 different resonators, learning the Science of helmholtz resonators, bolting different crap up to the exhaust countless times. Yes, an exhaust opens up some more power. But it's the subtleties- Turbo flutters, vibrations in the gas pedal and stick, less lag in between shifting, you just feel much more connected to the car. I'm manual, but get DSG farts, except they're not DSG farts, they sound like gutteral bombs exploding in the near distance. I FINALLY got it dialed in, and she nasty 😅
What are you running ?
Damn
Bro what’s your set up?
Like the others mate, what are you running? We all just watched a video listing mods. You talk about your exhaust and leave everyone hanging.
My fault, I never check the comments!
*AWE Track exhaust
*Vibrant 1974 Resonator
*Unitronic catted DP
(Get the res welded, trust)
The intake made the drone worse around 2000k rpm, until swapped as well.
*APR Open intake
*Unitronic Turbo inlet
*ARM intercooler charge pipes
*ARM Intercooler
I noticed a good portion of my drone was due to inconsistent breathing of the car. Once she was free to breathe on both ends, the drone was minimized with a very mature exhaust note (for a 4 banger).
Hope this helps
Anyone here who needs to rebuild their HPFP it is super easy, it is not labor intensive! It is a basic piston design, I have done it multiple times on Mazdaspeed 6's and 3's and several other cars. It seems way worse than what it is. I do not blame anyone though for doing a direct swap just keeps the install time down, but the HPFP rebuild takes like 5-10 minutes once you have it out. Anyways amazing video!
For those on the R platform it’s the same mod list minus the LPFP for full E
U mean hpfp bc I was told is38 hpfp is useless
@@prestonfields6642 no I mean what I said. You don’t need a LPFP upgrade for full E on the R/S3
Glad I stumbled upon your channel. Just got myself a 2020 GTI. Looking forward to building mine.
Don’t forget the clutch for the manual boys!great video tho man can’t wait to make some power with my gti
My mkv was DSG and I just recently got a mk7 and was like I love driving manual imma buy a manual. Then my friend who has mk7 told me you gotta replace that clutch anything over 300hp😭🤣
Man that was super legit simple. One of the better simplest,very well explained, attention to details in you personal experience of what works and what doesn't!
Kudos ✌️😎
Awesome build man 👌👌👌 what a champion for not forcing this 4cyl beauty into sounding like 8cyl 💪💪💪💪💪💪💪💪💪💪💪💪💪💪 the real deal 🤝
Watching your videos makes me think time to trade in my 2019 wrx for a volkswagen .The volkswagen has more potential to modify then the wrx worrying about blowing up the motor
Those flat-4 engines have narrow bearing journals and narrow crank pin journals to minimize the engine rocking-couple vibration but that doesn't bode well for lubrication if the should be any oil pressure drop. Inline-4 is just a better place to start for building HP.
Dude, thank you for making this. Came across your channel while looking for turbo inlet pipe/hose videos. I’ve got an 8v A3 1.8t and the MQB platform across the board is very similar per application and model, which is exactly why Your videos can have some degree of benefit and info for myself. Again, thank you. Got my sub for sure man. For sure.
I agree with all you said my friend, but with those light weight wheels I would add a 2 piece brake rotors stock size, that would shave some rotating mass, I did it to my MK5 GTI and you can feel the difference in pick up.
Is it daily certified and also do you need to build the internal to make tht power reliably
I also think Jewel deserves a lot more subscribers
great breakdown! ive been following your channel for a while
Any tuning program recommendations for an audi a3 2.0t that offers custom e mix tunes? Clean gti btw👌
Also if you have a 6 speed manual transmission is better to upgrade the clutch ,you have said it in previous videos that's how I know loll
Hey was wondering if you paid someone to do your clutch or did you do it yourself? And if you changed the flywheel. I’m at 66k miles and wondering if I should save up and change it later or if I should be fine going into stage one with the clutch I have rn?
Great video, thanks for the inspiration, I’m gonna order my cts catless dp and then I’ll get an intercooler and hopefully find a good deal on is38
What’s 1/4 mile times on something built like at?
Hey Jewel! Love the video, thanks for the guide. I'm super beginner when it comes to tunning and have a very dumb question.
Would this setup or similar work on a MK7 automatic? Thanks if you see this, cheers.
The mods apply to both auto (dsg) and manual cars
Great, thank you!
Any concerns about crank-walk with the high performance clutch and additional power?
Finally someone not lowering the car to ugly level.
Thanks for the great info, if I may ask did you do a dropped suspension on the car and if you did what did you go with?
Vwr lowering springs
Stock internals?
Hi, 1 step colder spark plugs. Can you give the name and part number? Thanks in advance.
and with the Walbro 450 did you just get the internals or did you get the bucket as well
What spoiler extension is that. It’s tight. The one linked in the description isn’t that same one
Have you see the new APR turbo for the EA888? I believe it's built off the MK8 R's turbo.
I've seen a few videos of it in action and I can assure you, that setup does NOT make 400WHP. I'd bet a typical IS38 on 93 would gap it.
Hey mate love the video and the build she looks great, Just wanted to ask what spark plugs are you running and is the front mount and high pressure fuel pump necessary for this hp? Thanks
At the time I was trying brisk and ngk plugs. You will need a hpfp for full e85, which is how you get 400hp. Intercooler helps maintain that power level
Yeah.... Big GTI fan.
Over 50... Enough said.
where did u get the silicone hose for the intake from
if one plans on just running pump gas is it fine without the fuel mods
first time watcher great stuff!! thank you
Good build, but idont wanna get hpfp when fuel prices are this steep, same reason i dont wanna go Revo Stage 2 as they say it consumes more fuel than Apr etc. With my present Stage 1 from BSR here in Sweden i get cheaper mpg when driving normal.
Personal preference i guess
I agree with you two guys, that’s why I added a Mini Cooper EV to my stable of cars , reminds me of my MK5 GTI that I still own, only drive the VW twice a week these days because fuel here in SoCal is pricey!
This builds my idol. Wish my white 17’ was this clean. Does a HPFP upgrade require any tune , especially being is38 now?
You will need a tune
@@JewelCity1Even w just 93 gas? I’m apr is38+ hi tq . Been reading forums and all I see is e85 needs it tuned. Always sumthn more building this car. 😂
Do you have a factory electronic lsd? Do aftermarket lsd's, like a wavetrac, bolt onto an open diff gti? might be stupid q's lol but fuq it, idk. Love the vids jewel, appreciate you g!
I have a wave track on my 2.0 vw cc
Your flywheel is it dual mass or single mass flywheel?
How are the VWR springs you installed? I’m curious to know as I am thinking of snagging a pair.
Made a video review here: th-cam.com/video/tPSewrqEXmw/w-d-xo.html
Sorry I’m very new to Audi/VW. Where I am there’s not many good tuners.
I’ve heard of the off the shelf type; IE, 034, APR etc but would like to know more about custom set up for big turbos.
Could you explain how this Cobb brand works with the tuning for your custom fuel system & turbo? Eg the files, is it from Cobb or an independent tuner.. will you need to log and send to the tuners to fine tune etc?
It's a port-access device for loading tunes. The tunes can be developed by companies like APR, IE, and others. The device displays all sorts of operation data while driving. The actual controlling of everything is done by the stock ECU.
Are those factory golf r headlights? or did you have the base headlights which you upgraded to the lighting package?
Golf r headlights. Car had the base non lighting package.
Nice,What do you do for strenghtening the brakes?
Upgrade pads/rotors. Swap for a bigger brake kit
Ive been looking for these wheels? Will they fit a stock GTI? I have the same exact. car all stock
how much the total cost of parts (without labour)
doing some research what car to buy for a project/weekend car
Is it better to have a local tuner or a Etuner (if E tuner do you have any recommendations?)
Local usually will be finished on a dyno that same day. I would say go with whoever can give you the sauce you want local or remote.
What r u planning to swap with those wheels bro?
Just looked up those Falken tires....of course they don't make a size to fit the GLI
Is this going towards the more power route, or a good handling route or kind of both?
This is more power focused. Here is the power and handling mods discussed th-cam.com/video/ynwkB5EYVyA/w-d-xo.htmlsi=ALxEQI10xEYxkb1z
Are you on stock clutch or aftermarket clutch?
Running mk7.5 stock but one day Santa 🎅 will get me a turbo charger 🤣🤣🤣🤣
Hello, how can i contact you about the product sponsorship collaboration?
What’s the total cost just for tyre and rims
Drop the link for the AP mount please.
Many thanks for sharing this with us all. Great info. Be safe out there.
Why cant i find any built 2 door 2016 gti..... i boutght one. Thwy are super rare nowaydays but jobody has any build vids on them....why
Hey awesome build man, followed your whole journey it’s awesome! 💯
Btw how did you achieve the loud blow off sound 6:49? Is it just only the intake and turbo inlet pipe? Or did you swap a aftermarket DV or Turbo Muffler delete?
You could add a dv spacer just for that sound. This was just intake/inlet
Is this the gen 3a or 3b
Ever looked into swapping into Trackslag DP
Hmmm th-cam.com/video/nyNSBQKIgRY/w-d-xo.html
Great video my boy 👍
your exhaust is completely oem, except by the dp?? The intermediary ressonator is still there?
Yup
@@JewelCity1 very nice... mine have basically the same setup and dont sound like yours... I'm thinking about to take the medium out for a biiiiit more sound... Tks for the anwser btw!
Does your high fuel pump use Golf R?
My GTI7 use is38 turbo
have some random misfire at 4gear 200km
I already change my fuel inject(golf R)
I don’t have change my fuel pump
Do I need to change it?
BTW(my Ignition coils spark plug is new)
Thanks 🥲
Probably the tune.
Will you be adding a new fuel controller like a PM4? Especially with added fuel mods and newer hybrid turbo? Is Cobb providing an off-the-shelf tune or will you be going custom?
car is currently running a custom basemap, boost controller is already installed
Older video so may not get a response but curious. Do you have any updates/upgrades to your transmission?. In short I'm running a APR Stage 2 2015 Jetta TSI but I'm running into slight transmission slipping (first one gave out and I'm on a rebuild). Running stock turbo with 8lbs of boost
All stock trans minus upgraded clutch. No slip thus far. Clutch was meant for a stage 2 set up but seems to be holding just okay so far with upgraded turbo.
I appreciate the response..... May have to replace the transmission entirely. I know the 1.8T (mine) doesn't have the dual clutch system so...... I may be screwed and have to drop a new engine 😅
Would u be upgrading clutch in future / maybe going single flywheel? Dkm/southbend etc ?
It’s already upgraded using dmf
@@JewelCity1 so is it the stock DMF? With a stage 2 or 3 clutch and new TOB? I was wondering if I could maintain the stock DMF since the whole clutch, pressure plate, and flywheel were just replaced for free by the dealer I purchased it from. Just trying to save money and possibly maintain the quieter DMF
@@BassMan9571 yes you can get a clutch kit that retains stock flywheel
@@JewelCity1 so I would just need pressure plate and clutch from stage 2 and I’m good to go. I’ll be keeping my is20 for a year or so then eventually upgrade. But it should be fine on stock DMF with just a stage 1 or stage 2 tune with a DP correct? I’m new to all this stuff lol
@@BassMan9571 run a "low torque" tune and you can keep the stock clutch...at least for a while
intake silencer modification ?
Can I get part number of your stock GTI diffusor?
Hey man, I noticed your said the golf r has dual LPFP in the tank. That is not true, the LPFP on the R is on the passenger side under the rear seat. On the driver side under the rear seat it looks like what would appear to be a fuel pump, but it is actually where you can disconnect the haldex. So it just one LPFP on the R.
Thanks for the correction!
what is the main difference between the OEM is38 and the is38+ because the price isn’t bad but is it worth the money
Retailers say it has stronger bearings etc. So it’s supposed to have a longer life than a vw/Audi branded one.
@@JewelCity1 does it die top end quick like the standard is38 does? how much psi can/or do you run
What spoiler is that??
Link please
What about intercooler??
What is the alloy wheels size ? r18 wide (j) et ?
18x8.5
wondering which HPA IS38 turbo or IS38 Hybrid Turbo you installed on your car?
It was an is38+ at the time. Now it’s a vortex hybrid
@@JewelCity1 Thanks! Ill try look it up
Would that setup work with a mk6 gli?
Hey man! I have the same car, it’s 2021 mk7.5 gti. It only has 11,400 mileage but there’s a creaking noise inside the car already. When I’m driving and hit bumps or like uneven road, you can hear it’s creaking inside. But it goes away if I’m driving for a long time. I’m not sure where it’s coming from, it’s sounds like in the door seal or something. It’s really annoying. Do you have the same problem?
idk if youre gonna see this but its a common vw problem its the top mount creaking or the bushes
Wich tune?
Is it okay if I wanted to go with a downpipe as my first power mod without a tune? Or do you need a tune to run a downpipe?
Car will still drive but might run a bit funky without at least a reflash
@@JewelCity1 gotcha, curious on what to do if I’m under warranty still, do the flash and risk it, run one without a flash, or just do something exhaust related not involving a tune
@@runofthemillz No need for DP without a tune. If you are worried about warranty go JB4 piggyback tune. Once you tune car it will show if scanned at VW.
@@medicalfrog_78 I hear ya, one of the reasons I even wanted a DP is bc I’ve seen lots of people say you don’t need a full exhaust system or much else to get a good sounding car while also getting great power gains from it so I was looking at just getting a DP for the sound but also a plus in power eventually
what is the small cone air filter next to the bigger one?
Crank case breather. I believe the stock just ran it back into the intake.
Did you have to upgrade the clutch? If so, what did you use?
This one th-cam.com/video/fKqcHhVHeCI/w-d-xo.html
Did you change the DV to hold higher boost?
Stock 😁
have you been getting dyno tuned for each part you installed like what steps should I take from going from stock to 400whp?
Tune = stage 1
Downpipe/tune = stage 2
Ideally you'd have a full intake/intercooler as well at that point.
Upgraded turbo = stage 3 (most go with the IS38/Golf R turbo)
@@MeltingRubberZ28 i have unitronic stage 1+ now i guess in order to go to stage 2 i need to do an intake, intercooler, and downpipe. i know i will get to IS38 eventually due to being able to hit 400whp
Awesome whip man, love your tasteful mods as I’m in the older crowd and I’m with you 1000% on the exhaust issue lol.
Golf R’s don’t have a second fuel pump. They just have a hump in the middle which actually cause a issue on higher HP builds.
Realized after upload. That’s my mistake
Just keep the rear seat delete bro lol, where did you get the wing extension
I wanna go full E on my 7.5! I’m already stage 2 I was just wondering what are the exact mods I need for me to go full E and if you could provide the links of the parts you recommend🤔
Made vid about it here: th-cam.com/video/KiNpumlyReI/w-d-xo.html
HPFP would be the bare necessity for E85. MPI and LPFP to get the most out of E85....but, they are not really worth it unless you upgrade the turbo past IS38.
What year?
Great video man! All I can say is don’t forget the clutch/dsg tune lol. Might want to also cut or open up some of the channels in that front piece from the oem intake and in the grill to let that thing breathe! Also wanted to mention a great tire choice for sure, I’ve always had great luck with Indy 500s though and is my go to here in Canada (super cheap). Maybe a dogbone would help some. Cheers.
Glad I saw this comment. I was going to mention the clutch myself. The stock clutch just can't handle much more then stock HP. Then of course, if you have the DSG you just need to make sure you tune the TCU as well.
@@austinm8823 he’s at 500 hp now on stock clutch?
I wish I could do this to my gti
What are you gapping your spark plugs to .020 ?
I’d do .27-.32
A manual and no clutch upgrade? What’s the mileage with this much horsepower? I liked that you started the mod list with the wheels. and tires. I do agree that’s the most important mod.
didn't mention but clutch is upgraded to hold the extra power
@@JewelCity1 which clutch did you go with?
@@Chris-qe6qr this one: th-cam.com/video/fKqcHhVHeCI/w-d-xo.html
Are you running default map on the Cobb or pro-tune?
Pro tune aka custom tune
What's the offset on the rims?
what wing extension is this?
Love the vids man, definitely would love to see a Dino video
Great video though man. You recording on go pro or phone?
How much did you drop for the list of mods?
hows the reliability? crankwalk?
Common water pump issue but that’s about it. Engine itself is holding fine. Latest vid has it in action
At what HP/TQ did your clutch start slipping? I’ve seen so many mixed answers. I want to go stage 2 but not sure yet.
my stock clutch never slipped, upgraded in advance
A stage 1 flash from APR will start a stock clutch to slipping.
does it feel a lot faster with ethanol?
Compared to 91, absolutely
What about the clutch? Every one tells me the clutch will not be able to take the extra power. I have an R BTW.
You’ll need a clutch. Stock doesn’t grip the extra power all that well. There is a clutch video posted on the channel if you want more info
Very nice 👌 content 👏
What size/ offset wheels & tire size 🤔
Keep up the great content 👏
Is there a way to hit 400 WHP on 93 octane? Nearest e85 to me is 300 miles away lol.
Upgrade the turbo so it can be done on 93oct
Link for spark plugs?
