Video Title: What To Know Before Installing an IS38 Turbo - Tips and Helpful Info when upgrading your Golf or GTI

[@kiliannelson5320]

anyone else have any misfiring issues after installing is38? I am running a eqt stage 2 tune w stock hpfp, and I have basically every other bolt on, the car runs fine just abt until I really floor it and then it sounds like a different car and starts misfiring after a few pulls. I also don't think I was careful enough taking out a cam shaft actuator and now have a check engine light for it and 1 of them cost 95$ so be careful when doing so. -Streetcamgti

Hell yeah! I love mine. Good luck with the install!

I've never even heard of this channel. Nice editing, I'm surprised this doesnt have a shit load of views, great job with all this. I have a 2019 gli, I just went through all this,pleasant to watch. Keep it up ^_^

Thanks so much man! Share the shit out of it, then I’ll have some more views. Only been around for a little while, but growing quick.

[@cheknocksya]

Good luck with the install! Make sure to prime the turbo without turning the car on so you can get oil and coolant in there before you actually turn the car on!

[@karstgeo7290]

Correct. Liquimoly even makes a special lube just for this purpose.

[@DadWagon]

Thanks! Will do!

[@jaxxhaggard2306]

and how would you prime a turbo?

[@samuelst-jacques8312]

​@@jaxxhaggard2306 i think removing the fuel pump fuse or some like that and start a few times. Maybe i'm wrong

[@geordonpride5874]

I back the scientific fact that an AWD wagon is definitely cooler than an AWD hatchback! I bought an Alltrack a little after you started this channel and I do plan on tuning and adding the IS38 turbo. I have read and watched a lot of content and gotten a lot of different answers. So my question to you and everyone in the community is what is ABSOLUTELY necessary to install on my car BEFORE I install an IS38? I’m trying to budget myself and buy only what is necessary, but I also want to do this right and maintain the reliability of my precious MK7.

[@EvilSe7en]

This is obviously pretty late but I just added an IS38 to my 7.5 Sportwagen. I have an IS38, a CTS intake hose and turbo inlet pipe, RS7 spark plugs (not that I’m concerned with using factory spec) and an APR tune. That’s it. After owning a 15 WRX and throwing tons of mods at it, little and big, trying to get the most out of it I’m excited to do less. Heading to work one morning I got behind a stock looking MK7 GTI and chased him around a left then right onto a long straight industrial road. My 315 AWHP WRX got left in the dust. This experience has informed every choice I’ve made with the Sportwagen. I will be doing an intercooler but as far as power modifications this is as far as I plan to go. It’s stock quiet, factory feel and my gf doesn’t even know I’ve tuned it, let alone added probably 100hp. But if I ever laid into it to merge on the highway with her she’d know something was up. It’s exactly the subdued monster I wanted.

[@lukemfross5533]

Early on in my search I was wondering if there was a nice twin scroll option as the header seems set up for one from factory but I don't think you can beat the value and performance of the is38 at least without having to upgrade every other part of drivetrain...

[@azf9434]

do I need the installation kit? Or can I just get the turbo itself and fit it in the oem is20 Monts?

[@Volks2462]

I have a Tiguan Allspace with the 2.0t 220hp / 162kw with MPI and is20... i want to also run a oem is38 effectively making it a stage 1 golf r with a tune. How important is the upgraded intercooler and would the original intercooler be enough since the plan is just a stage 1 file ?

[@xanderwayne7938]

Here in Europe the golf R as wagon option and is way more common 🙃

[@encryptgti9193]

Can i do all this with the stock intercooler on my 2016 GTI?

[@limitededition3278]

Nice turbo good luck with install. My question for you or anyone is the following? Aside from down pipe and intercooler upgrade do GTI owners need to get a (HFFP) High Flow Fuel Pump before installing IS38? Thanks! 👍 You have a new Sub.

[@travisstokes7342]

question anyone run the is38 on a stage 3 tune ment for the is20? I also have a dadwagon 2017 sportswagon tsi. I currently have the downpipe, intake and a stage 2 tune through IE. but they don't make an is38 tune yet

[@lukemfross5533]

Would love to see how the install went!

[@DadWagon]

Coming soon. Less than a week out.

[@DadWagon]

Thank you all for participating in this discussion! Looking forward to seeing what we can generate together. *QUESTION: When installing your IS38 Turbo swap, what part of the install did you find most difficult?*

[@mikerosenthal1977]

Are you planning to do any alterations to your DSG tune when installing this turbo? Also, do you plan to do this turbo install yourself? (I have a '17 GSW 4 Motion). Keep up the good videos on these hidden gems!

[@DadWagon]

My DSG is currently tuned with Stage 2 from Unitronic - i believe this is what's suggested for Stage 2+IS38 ECU, so no changes are planned.

[@HKDriverMike]

@@DadWagon Not sure if this is useful or not. My car is a golf R mk7.5 and it comes with is38 turbo. When I went for apr stage 1 high torque version upgrade, I did some research and found out that the car also needs a tcu tune to prevent clutch slip. I am not sure whether you will also need a clutch upgrade for IS38. Just for your information😀 Thanks for making those videos. Love it as always😍

[@mikerosenthal1977]

@@DadWagon Are you rocking the stage 2 ECU tune as well, since you have the DP, intake and intercooler?

[@DadWagon]

[@Vaguh]

"While you're in there..." is there an exhaust manifold (aka header) upgrade that could be done? This is something that I NEVER see mentioned in performance upgrades on Golfs, so I'm unsure if it's just not typically done because it's a PITA (like front sway bars), or if there is just generally no performance gains from it because of the extremely short run from the exhaust ports to the turbo.

[@jasonmay6565]

There really isn’t much of a header on these cars, and it really doesn’t make a difference, so that’s why you don’t ever see it discussed. The turbo basically comes right out of the block

[@740GLE]

Intake manifold with MPI is def an upgrade, I think I’ve seen some Aluminum ones. The exhaust manifold is in the turbo and there are other options other than IS38 but then you run to fueling issues.

[@740GLE]

Plug in the Wastegate actuator connector before snugging the IS38 to the head, the connector is rotated compared to the is12-20. Also be careful of the top coolant port adapter on the head, the plug is plastic, it maybe best to have a replacement on hand in case you snap it. IMO if you’ve installed the DP, the Turbo swap is just as complex just maybe a bit longer. What’s next after this? HPFP upgrade? MPI + Intake cleaning DIY? Too bad unitroic doesn’t support MPI.

[@DadWagon]

Thanks for the pro tips!

[@eatthellama9140]

You mentioned updating your intake and intercooler before your turbo install. Is this something that has to be updated or tuned after install?

[@DadWagon]

Most of the companies who make the IS38 stage 2 tunes consider a new intake, Downpipe and Intercooler as required modification to run the IS38.

[@guiseppevanoni6268]

If I want to install a is38 on a stock 2017 alltrack what should I upgrade on it before the turbo? (Necessary and recommend)

[@DadWagon]

Downpipe, Intake, Sparkplugs, Software - these are all generally considered required, but I've seen arguments for all of them being just recommended.

[@abruechert82]

Can you get into the 12s with an is20 or would that require an is38?

[@mcwendel8066]

kzbin.info/www/bejne/qWKumnarhpeAmpY

[@tommytruong3350]

Still deciding for a daily whether to go is20 or is38. Have a buddy that will sell an is20 for $200. Is the is38 much more noticeable/worth it in power then the is20?

[@DadWagon]

After tuning it seems to be a difference of about 50hp and 10 ft/lb torque difference. I can't say from a true driving experience since i haven't done it just yet :)

[@H2oToGoWH]

You can run the is20 on a jb4 and won’t void warranty and avoid having to tune it so your car won’t be flagged if you’re under warranty, as for the power difference it is noticeable especially at the top end as the is38 can carry the power a bit longer, only downfall is spool time. The only thing I can strongly suggest for an is38 is upgrading the fuel pressure regulator from a gti or an r, though the 1.8 can handle it, it’s definitely a safety net and less ware on it.

[@FreekaPista]

Is there a significant difference in response between the IS12, 20, 38 and Hybrid turbos?

[@karstgeo7290]

It's there but not as much as you may think. I've had each on my 4Motion Sportwagen complete with logging and Dragy times. The 12 certainly is the fastest spool but of course dies off up top fairly quickly. The 38 and 20 are closer but again the 38 keeps on pulling up top.

[@yacluck8343]

@@karstgeo7290 how's the reliability with the is38 on a 1.8t?

[@abruechert82]

Will an IS38 upgrade be safe without any other supporting modifications besides the downpipe? Are intake temperatures dangerous with the stock intercooler?

[@DadWagon]

All tuners suggest/require upgrades intercoolers, intakes and Downpipes. I assume there are reasons beyond just making money. At a minimum I’d assume at least going with a golf r components may be safer. Is12s we’re utilized to save cost - so it’s safe to believe that vw saved costs on the IC and down pipe as well in non r models. With the cheapest components or used items you’re lookin at $2500 usd. My setup with tuning is closer to 3500

[@andreasford274]

I know I'm about a year late to answering this one, but if it helps, I have personal experience: Is it safe? Yes. But does it perform? No....well kinda. I blew through two IS12 turbos (wastegates stuck open, known issue). First one was under warranty, second wasn't. My independent shop happened to have a used IS38 with about 10k miles on it, offered it to me for half of what a replacement IS12 would've cost. I was low on cash at the time, so it's installed with zero additional equipment, just the APR IS38 tune. When it's 65 degrees or lower outside, it's a massive upgrade over the IS12, especially from 3,000 rpm up to 6,000. But running it hard for any length of time and/or at high altitude (like 10,000 feet, I'm in Colorado), it'll suffer at the top of longer climbs at highway speeds. I believe they call it heat soak? I have about 50k miles on this IS38 so far, zero issues with repairs. I'm very likely doing this again when I buy a younger Alltrack, but when I do it next time, I'm adding additional parts, bare minimum a better intercooler, very likely cold air intake, and possibly but not likely a downpipe.

[@marcopolo9407]

Looks like the intercooler is the hardest part?

[@DadWagon]

It's a toss up between the downpipe and the intercooler. Both relatively time consuming - especially when trying to film it with a one man crew.

[@Ericej2344ej]

How much low end power will you lose with the is38 upgrade?

[@DadWagon]

I’m not sure how to quantify that for you as I don’t have dyno comparisons, but it doesn’t feel like that much. I haven’t missed it since installing the IS38

[@Zharsergey]

Interested to know if you have to remove the downpipe completely to gain access

[@DadWagon]

I sure hope not - really don't want to have to take off the prop shaft again.

[@danh1807]

I'd be surprised if you're able to do it without pulling the downpipe, the leverage you need for removing the oil line on the bottom of the turbo (assuming yours is as stuck as the one we did) just doesn't seem possible from the top side.

[@Zharsergey]

@@danh1807 What about leaving the line attached to turbo and remove it from block instead?

[@danh1807]

The line on the block is even more buried by the downpipe than the line on the turbo, from my recollection it would be harder to get at. We also tried removing it from the block when we swapped a turbo, but found that the factory line was just as stuck at the block as it was at the bottom of the turbo. Enough wiggling the turbo around and enough curse words, and we eventually got the line to free up on the bottom side of the turbo.

[@jasonmay6565]

You do not have to remove the Downpipe. It can be done by unclamping it and pulling back. The flex section will allow some movement. You may have to unbolt one or two nuts but that’s all.

[@themikepietersen]

I find the GSW / Alltrack awesomeness order placement rude. The Alltrack is clearly more awesome. It should be ordered furthest to the right.

[@DadWagon]

The alltrack is more awesome if you like spending more ;) It does depend on what GSW you get.. 4 motion FTW

[@evanacevez4741]

I’ll take turbo muffler

[@5Minuteman]

Whats the mileage after?

[@DadWagon]

I don't have any specific metrics - but it doesn't feel like I lost too much in gas mileage. My gas mileage does suffer now, because I really enjoy steppin' on it.

[@prs314]

Copying my comment from ShopDAP install video on the bottom line triple square bolt (kzbin.info/www/bejne/kHzCY6ybdqqomK8): I found a good way to approach it: 1. take the long M8 bit from ShopDAP's Triple Square Socket Set and a 10 mm ratcheting box end wrench. 2. Use the wrench as an additional guide at the bottom of the socket 3. You can see the bolt from the front of the turbo, so use your fingers to connect the bit while actually looking at it. Go behind the actuator rod (as shown on the video) not in front of it.

[@DadWagon]

Thank you!

[@prs314]

@@DadWagon Another thing I've picked up from the FB Turbo group is that Unitronic Stage 2+ may not be playing well with all actuators, especially if they are from Audi. I had to swap the actuators on my turbo (Shuenk IS38+) from OEM IS12. Also, calibration procedures for those actuators are different! Is your wastegate closed in resting position (without any power)?

[@ianmartin05]

I have heard the downpipe is not fun or easy to yank

[@DadWagon]

on the 4motion models, it can be a little bit of an exercise

[@deeezobrown]

If there turbo is already out, but be able to feed the downpipe from the top. But yes, typical install for 4motion DP is a bit extra work when dealing with the driveshaft.

[@charleshollow5734]

I'm super excited I found this channel. I've been a volkswagen nerd for the past 24 years. My first car was an 88 golf. I currently have a mk1 cabby project that I am swapping a built 16v 9A into. My daily (a 2013 scion xb, dead reliable but quite boring) was totaled a couple weeks ago (dashcam video here: kzbin.info/www/bejne/Y4fQdIehe6x3rNk). I always like the golf sportwagen since they came out, and I thought one would make a great daily. I picked up a 19 GSW 4mo DSG last week, and it has me SUPER pumped. This is my first forced induction car, and I'm really looking forward to making it a bitchin dad wagon of my own. This video in particular has me drooling over the thoughts of swapping in an IS38 turbo. Do you have any thoughts on keeping my daily reliable while having some fun with it? I'm insane about maintenance as it is, and I want my cars to last. Thanks for the content!

[@DadWagon]

1. That dash cam footage is crazy and scary as hell. I watched it like 8 times. Sounds like you and your son are all ok? 2. Thanks for sharing the super thoughtful comment with so much background. Sorry to hear about your scion. I had one for a few years, and absolutely loved it... so slow... but so simple and reliable. Super stoked for you and your GSW. You're going to love it. 3. thoughts on keeping it reliable while having fun - 1. Try a stage 1 tune first. It requires nothing but software, and will add a ton of fun and spirit to the drive. with that and a rear sway bar - that might be enough to keep you happy. Try it out and go from there.

[@charleshollow5734]

@@DadWagon Thanks! We both had some bruises from the seatbelts, but no soreness or any other problems. My son is still a little shaken from the whole experience though. I am waiting on a turbo muffler delete, luft-technik inlet duct, 034 "insuction" bundle, and a neuspeed piggyback. That should keep me happy, for now...
