Big Turbo 1.8T MK4 GTI easily makes power. Not your average street car.

[@COMotorsports]

Hope you guys are enjoying the content.

[@jaygray99yo]

How does the stock trans hold up to power above 500 ?

[@nakedrobotmonkey7550]

Yeah man. Too cold in my garage but makes me want to go work on my 337 GTI. Thanks for the inspiration.

[@ps_n_sq5]

I just got here and I’m already beginning to enjoy it! Much love! 🤘🏼

[@brooksallenyoung]

Of course

[@stephenspringer8100]

Loved the intro on this one!

[@stevenwhitehead426]

Love the Black Forest industries parts! I am a Volkswagen technician at their sister company Black Forest Technik!

[@Thumper68]

I had a 2001 Jetta Wolfsburg with the 1.8T all I had was an aem cold air intake an exhaust and a custom turbo down pipe but that car moved pretty damn good it definitely surprised a lot of people lol

[@ryantempleman6551]

Yup now I got to put a motor in my 20th it been broken for a few months and it’s time awesome video keep it up

[@bakafunny8386]

can't wait to build my 1.8t

[@VeedubbinVR322]

Love watching yall guys keep up the great content

[@cupraboyz9469]

1.8t FTW ✌️👌

[@aknk6759]

The video i waited for a month❤️😂😂

[@COMotorsports]

This has been sitting in the hopper. We needed to get past the holidays and stuff and get back on track.

[@aknk6759]

@ thanks for your hardwork to share with us. I have some questions if you dont mind. How high are you revving it, i checked the video serie twice but i am not sure if it is stroker or not. And when exactly it spools up? Thanks again

[@tptrsn]

This one is a badass!

[@gpa-q1d]

Thanks!

[@COMotorsports]

Greatly appreciated. ❤

[@AlainK-Official]

Waiting this thing with patience - You are the man, 658 WHP with safety margin 😂 - Happy New year to you and your staff

[@danielweinbaum]

Try R1 Concept Brakes ! 4 wheel st pads and rotors for around $350 for a GTI on Amazon! I am not affiliated with them at all, just impressed! Slotted and drilled with pads! I got a st put on my 2018 Honda Odyssey, this is my 5th Odyssey and every one had warped rotors! I called 3 Honda dealers and got 3 quotes, $850 for a resurface and pads, one for $1100 new pads and rotors and $1200 new stuff. I bought the R1 Concepts brake kit and brought it to my guy...the box from R1 was $387 and my guy charged me $400! Incredible brakes ! Black coated !

[@COMotorsports]

@@danielweinbaum this has a big brake kit on it. Part of the issue is the lines were left disconnected for a very long time which also drained the abs pump. We'll get it sorted.

[@Skirasa]

Gosh that’s a lot of power

[@josephkelly4893]

Love a spicy Mk4

[@BCAlltrack]

Love the 1.8T content. I have a newer EA888.3 that is trying to get where you are!

[@SimplicityFab]

You guys made putting that damn engine in looks easy af lol… im no longer lifting my car to remove the engine lmao

[@andrewmartinez1667]

More than 6 months waiting following every part to this series you guys are the best this beast looking amazing making great power very very nice great content guys !! Whats a cost of parts only for something like this ?

[@COMotorsports]

@@andrewmartinez1667 Thanks. This has pretty near ever piece upgraded that you could think of...and I'm being serious...so a lot.

[@Tagomago12]

When you see a low pressure fuel pump like that going in you know what it's about.

[@gpa-q1d]

big ups, any 1.8t i’m in

[@Tagomago12]

I'm more of a ea113 guy especially the cdl version ( more torque) but your uploads are always appreciated.

[@COMotorsports]

@@Tagomago12 it's not really any torque'r. It's just the nature of a turbo this size on a 4cyl, also cams etc. A similar setup up ea113, would look similar really.

[@JohnDoan-iu7sm]

If people are shipping cars from all over that tells you these guys know their stuff. That’s got to carry some clout. I would ship mine if I could. Good on you sir.

[@LoFi_Chillz]

I have a turbo S Beetle with the 1.8T AWP engine. I really would love to put a big turbo on it 😮

[@okvic77]

🤟🏽🤟🏽🤟🏽🤟🏽

[@BOOSTEDDUDE]

This is one amazing setup! You did an awesome job and know a ton about tuning a 1.8t. Did you do all the tuning? I would love to see this run against Jewel City!

[@COMotorsports]

@@BOOSTEDDUDE yes, this one is tuned by me.

[@BOOSTEDDUDE]

@@COMotorsports That's awesome! Do you also offer tuning services?

[@COMotorsports]

@@BOOSTEDDUDE yes, email us

[@sebastianlorenzo4935]

Another One ( dj khalid voice) Thanks guys. 👍

[@DZGunner]

the immobilizer light is purely key related

[@DZGunner]

but it won't affect the car in any way, normally it would disallow the stock ECU to start, but sinse you have the EMU it doesnt matter

[@COMotorsports]

@@DZGunner I do immobilizer defeats all the time in VWs, and have also ran this ecu in other VWs without this issue. Something else is up.

[@ramkaz7491]

Great content! I'd be interested to see how much it ends up making on only 91.

[@noad890]

What’s a good power to enjoy the 1.8t? I have ko4 GLI and wanna go more is it worth it? Thanks

[@luvs2spwg629]

I have a cts big turbo kit with the basic T3\T4 garret T50 trim and I easily push 550 with rods and pistons. I constantly blow axles. 😎

[@COMotorsports]

I think you should dyno it. 😉

[@colinmurray6741]

Hell ya

[@Golfzla]

Where did you get the firewall shield?

[@talanr6629]

Love the content. Many entertaining yet very useful videos. But also how would I reach you guys about working on my Big Turbo 1.8t Jetta? Or even how can I ask a few questions about it? I've got a lot of hiccups I cant seem to get iron out.

[@COMotorsports]

email us.

[@Ethan-ui1jx]

would love to see the tuning side with timing and power enrichment and also would love to know if this is a stroker or stock bore and stroke forged setup. are the 8740 rod bolts the upgrade path for these? Also what are piston ring gaps. sorry for all the questions but I love the nitty gritty details. Love the channel been following since the beginning! I have my own built 1.8t also and enjoy the content. keep doin what yall are doin have a good one!!

[@COMotorsports]

If you've been following this build then you will know we did not assemble the bottom end, I just replaced bearings. It is not a stroker.

[@jamesatkinson120]

Hi what’s spool like on this turbo what rpm is full boost and is it still a 1.8 or is it a stroker thanks

[@quetzalcuber]

How did you learn to build and tune? I'm new to building/tuning, and am interested in building my mk4 gti! I have a 1.8t with a simple stage 1 tune, upgraded downpipe/exhaust, better diverter valve, etc. Sometimes I get stuck on what to do next. Thanks!

[@COMotorsports]

@@quetzalcuber books, courses and a lot of spending money, a lot of trial and error. Best way to learn is by wrecking your own stuff.

[@jungillestt02]

Id love to see a 02 audi tt awp on here. I have one and want to make a fun street car. Picked it up because it has the wideband and higher compression than the 225. Does anyone know a company that makes a e85 kit for these cars?

[@MBMotorsport]

Good job Sir ,keep it up

[@simonell6573]

Precision next GEN and when does boost start rolling in?

[@COMotorsports]

If I remember I think I show boost graph on the dyno.

[@Jakey959]

Can you do a full anti-lag that builds boost like the old Suburu just with your ECU, also can this be done on an ME7.5 stock ECU too?

[@COMotorsports]

Yes, no rolling antilag on stock ECU. Well maybe someone's in the world has figured it out but the short is no.

[@Jakey959]

@@COMotorsports Niiiiice... I have an AUM 2004 its stage 1+ around 240whp, im about to fit my third o2j box would you recommend a half cut built gearbox as the input shaft seems to crap itself all the time? Thanks for the reply, keep up the great videos. 😎

[@owen8271]

She is a beauty. How many hours did you put into this beast?

[@COMotorsports]

A lot lol

[@yulmerced4434]

What motor mount are those?

[@MxhzlC4YHGaming]

BFI stage 2

[@pudermcgavin4462]

I'm gonna spend more money on my 2015 tsi I want to see stuff with the 1.8t with a 5 speed trans! My transmission scares me

You’ll be Ight
