MK4 1.8T Big turbo build.

[@shiftya4]

I have a mk4 GTIsitting on the side of the house with a 67mm Garrett and all the supporting mods& water/meth. I just wasn't ever able to get it happy it was so finicky. Watching your videos has inspired me to give it another run. Really like when you get into engine management I'm always learning something new. Great channel 👏

[@COMotorsports]

Much appreciated, we've made 700ish on a 62mm on a 1.8t so you have lots of potential there.

[@scotiacoastyachts1]

You have just busted everyones HP ego that have stage 2 tunes, you're a bad man!!

[@COMotorsports]

Spittin facts. :)

[@andrewgilman2202]

just started my blue lagoon gli big turbo build as well. I have all kinds of parts on the way as I see this video. Gets me so stoked to start putting on go fast bits!

Good luck with your build.

Awesome channel. keep the content coming. I have an imolla MK4, but you are right the blue ones are the best.

Imola's good also, however this color is hard to top.... and I don't even like blue.

[@Elswalbe]

makes me miss driving my mk4 Wagon with a 12v swap!

[@psavel274]

Totally agree. I miss my '91 gli with a fully built AAA swap. Very clean mk4. Looks close to mint from here. It definitely needs a cooler to address the heat soak, and of course some poly mounts, especially a dog bone from the looks of the engine rock. Only thing I despise about them is the stupid pcv setup and the emissions junk. With a real catch can and emissions junk gone, they are a great bang for buck powerplant. The gli's are getting more and more rare around here. It's nice to see more three pedal cars and not all dsg's. Clean looking caddy in the next bay over. Do I spy a 24v swap in there? Its tough to see on this beat up phone.

You sir have impeccable taste. Ive got a ‘92 rabbit cab with a 20vt waiting to be dropped in here... been procrastinating about going K04, not sure there’s much point with all that chassis flex, not the best handling car

[@COMotorsports]

I've never been a fan of the K04 on a 1.8t so you're not missing much.

[@ervinhernandez3137]

I want to see the whole process , because I want to learn all that

[@COMotorsports]

Follow along. :)

[@ernieandreoli249]

love the build! did you say actual timing was 5 to 8 degrees after it pulled due to heat etc? I think you said 91 octane it was running realizing its limited due to octane. guessing 93 octane @ 20 psi 10 to 12 degrees what tuning software do you guys use? Thanks again for sharing your time and knowledge.

[@COMotorsports]

First pull (cool) it was pulling 5-8* out during the pull. More after it got heat in it as you can tell by the results from the dyno runs. This currently has Uni, we will be changing that.

[@jamesschulte5278]

Aren't they supposed to make around 180 from the factory? I know all Dyno's read different, but man you nailed that guess. Lol.

[@COMotorsports]

180 crank hp yes from factory. We're measuring power at the wheels.

Fun first car for sure.

[@Crypto_Chino]

Awesome video !! Im kinda bummed and cant believe a stage 2 pushing 21 psi is only 180whp...really thought it was going to be about 220-230whp.....with that beeing said ive the seen the K04-001's push about 230-250whp and the the K04 hybrids push about 260whp+ like (F21 Frankenturbo)....

[@COMotorsports]

K04's are useless on this engine IMO, I've yet to see anything in person make any sort of power... maybe 230whp. Definitely no K04 1.8T's making 260whp around here. As for the power this car makes... as mentioned at the beginning I was sort of expecting around this power so not much of a surprise to me. We're talking real world results, not fudged hail marry dyno numbers.

thanks, and yes a 28 has the potential for a lot more flow compared to a K04.

So do you get the eight credits when you buy the first Urodine maestro seven or do you have to buy credits also

[@COMotorsports]

I guess that would depend where you purchase it from.

[@sparky5879]

With a stage 2 tune on that setup shouldn't the hp and tq be higher then that?

[@COMotorsports]

It's running 91oct, and this is WHP not crank HP.

[@action76news]

I only need about 380hp/380trq to the wheels 1.8T JETTA GLS you think

[@COMotorsports]

Lots of things that come into factor. The first being what mods the vehicle currently has. If it's stock you need to consider things like exhaust, intercooler, and clutch... and the stock stuff won't handle your power requirements.

[@vanystuart551]

Hallo wich log do you use to see that noting going on

[@COMotorsports]

Depends on ECU, and what software we're using.

170 psi of compression?

Each build is different, depends on power goals, what the vehicle is being built for, and what mods are existing on the vehicle. If you'd like drop us an email with the answers to the above questions and we can work out the details further.

[@kool-aid8085]

Can you run stock injectors with a ko4 turbo?

[@COMotorsports]

Depends on the software you're running. Some increase fuel with an increase in fuel pressure. So it all depends on the correct software and correct FPR to match. It would not be wise to run a K04 on completely stock fueling.

so weird that it made 180 on a stage two because stock they make 180, unitronic advetrtises stage 2 as 245hp 275tq

[@COMotorsports]

Wheel HP is different then crank HP.

[@COMotorsports]

Also their stage 2 is supposed to be 93oct, but all we have here is 91oct. The big difference though is you're comparing crank HP to wheel HP.
