EDIT: April 2018, new motor
We did it. We k04 now!!! Now to maximize its potential...
EDIT: Feb 2018
E30 blend, Mabotech tuned
Made 356whp/355wtq on dynojet in 85F in Florida heat. Comparison is ots eurodyne k04 file for pump gas 93 octane. Major gains!

Showing off some Mabotech apparel.

EDIT: December 2017
Mabotech tuned k04
pump gas logs- need to update the link

The beginning steps on the road to k04, which is now no longer the road to f23t FrankenTurbo.
This is the story of my first car, my first manual, and my first mod streak. When it was time for me to finally get a car, I had my mind set on 2 vehicles WRX STI or GTI. The sounds of STIs 'rally cars' riding around always caught me eyes. And my fiance drove a mk4 GTI, so I was also familiar with the 'hot hatch' capability. I knew I wanted a manual because I always wanted to learn. My dad drove a Stage 1 Jetta GLI VR6 6MT so I knew what Volkswagens were capable of doing. Long story short, what sold me on the GTI was the superior interior. Purchased in May 2013.

The story

Apparently someone liked my car in the snow (I love you!)

I learned the stick on the Jetta then transitioned to the GTI. My first task was driving it 500 miles back to Michigan for school. We made it but lets just say I was far from the greatest at the time. One year later, here I am comfortable behind the clutch and starting my mod journey.

So initially as most youth do, I put a sub woofer in the car. 8" enclosed Polk sub with matching Polk amp in case I want to do later sound upgrades. As with most stock systems, the lows were lacking.

Then I joined this forum and I caught the mod bug. By the end of the first year I had purchased an P-flo intake, Neuspeed 25mm front and rear sways, and APR 3" exhaust.
And then I met the MIVE (Michigan Volkswagen Enthusiast) community. And boy have they been helpful with the VAGCOM and mechanical advice.

Plans for tuning the car are down the road. I want to wait out the warranty some before I really get into the modding. But I am still looking to have some fun in that mean time.

Some old mod reviews
Reserve for Mod Review

Clutch Stop- Amazing. Who knew that much petal travel could be eliminated. My leg thanks me. Best mod you could do for $10.

APR 3" turbo back exhaust- I love this thing. Quiet when I need it to be. But loud when you get on it. And it passes the wife test so it is definitely worth it. No fitment issues.

P-flo intake- Inexpensive RAM air intake for the extra whoosh sounds. Easy install.

NewSouth vent pod- It was easy to route through my existing routes for the subwoofer. Bought it used so had a little trouble with the wire taps, but after some new clips and adjusting, we got the gauge working properly. Now I can finally see my stock 10psi. [emoji2]

Neuspeed 25mm rear sway bar- Car definitely feels better in the turns. I have it set to the stiffer setting and it feels good so far in the 2 on ramps I took this evening. Only concerns iare potential noise from the new endlinks and having to re-grease the bushings in about a year. First impressions are I made the right choice on the hollow bars.

Soundaktor delete- Coupled with this quiet turbo back, I can finally enjoy my soothing wind noise.

Color Matched Emblems- This was just something fun I wanted to try and I think it looks pretty clean. The front looks a tad bit more aggressive. The rear looks more uniform.

Enkei Fujin- These rims are about 5lbs lighter than the Lagunas. The weight reduction on the butt dyno is reasonable. I think I can feel it some. I went with 7 spokes because I do not like even number spokes and 5 spokes are too common.

The rest of the reviews are integrated in the posts.

Good stuff. Where about in Michigan?


Go Kart Champion
I'm just north of you in Pinckney.


Might I suggest a set of LED tails on your future cosmetic mod list? Reps are only like $350. OEM are closer to $600 though. I went with Eds Reps and they've been good. They much improve the back side of the car.


On a CSG for ya:

and for stock comparison:

They are definitely in my list for next year. Everything above I own, just is not on the car yet. I love the LED look. Thinking dark cherry w/fog

I put my dogbone mount in about a week and a half ago. At first I was a bit worried because as soon as I started my car there was a good amount of vibration. Also when taking off from first I felt like I wasn't giving it enough gas (even though I was). Well, ~600 miles later and it has "settled" and isn't as rough feeling. I'm really not sure if shifts are crisper or if I get better throttle response. Let me know what you think when you get yours in.

Does that have to be stop and go mileage or can I just put 500 highway miles on the mount and call it a day?
I will let you know how it feels when I get a chance to install.

I'm not sure if it makes a difference WHAT kind of driving is done. I'm definitely not the expert on it. Daryll at HPA would be the man to ask.
