My second build on my 08 GTI

[GIACUser]

I have owned this car for 10 years. Mods started early and I blame this forum and all of my fellow enthusiasts for the low balance of my bank account. The car graduated from stage 1 to stage 2 to K04 with a number of mods to accommodate the increases in power along the way. I had been driving it for a number of years at the K04 level (335/336). In 2017 I decided to refresh the car and go bigger turbo, bigger wheels, bigger tires, bigger brakes and some enhanced seating and am hoping to land somewhere near 500whp. As of 2/27/2018 the car is about 70% done. It will be going to AU Tuning in a couple of weeks for all the final assembly and tuning to get it on the road. Once on the road the fender flares and big wheels will go on.

March 27, 2018 - car went to AUTuning

Update 9/13/2018 - The car is still at AUTuning and it is nearing completion. I decided NOT to go with flared fenders and oversized tires and stick with my stealthy stock look and just refresh the black plastic pieces and grilles. I also decided just this week to replace the YCW coilovers and went with Eibach R1s. In working with Dave at AU he has a solution for a 5th injector on hand if we need it to reach the power level I am happy with. Hopefully the car will go to the dyno for tuning in the next week or so.

As you can see by the list below, this build was rather extensive partially because I chose to replace most everything that I thought might fail on a 10 year old car. Much of the information below was scattered over a long thread I started years ago for a previous slow motion build if you will. I thought I would compile and update the information here just for the new build. This build should have been done months ago but timing is everything and after many stops and starts the project is nearing completion after taking the car off the road in July of 2017.

The build is oriented around track use (road course). It is fun when your car accelerates well, handles well, stops well and can be beat on all day long without burning up. My K04 setup fit that theme well and it was a ton of fun. This build takes all of the good things I learned and turns it up a notch with significantly more reliable power, better suspension, better brakes.

It will not be the fastest MKV out there by any means but it should be a very fun track toy if my past experience has guided me properly. I sold off almost all of my old performance parts that could not be reused for this build and replaced them with new so there was little equipment carried over. The APR intercooler was about the only thing I kept as it was in great shape. Oh I did keep the 42DD 3in Turbo Back exhaust system but I will be modifying it to a 3.5in catback with Burns Stainless Quiet muff.

Update 3-16-2019
Car finally coming along and on dyno yesterday for its initial 91oct tune (347 to the wheels) more tunes coming for all combos of meth and 91 and e85.

Update 3-26-2019
91 oct only tune - 370whp
91 oct and meth - 420whp*

*Eurodyne issue is limiting boost to 22psi, Dave originally felt he could get to 450 on 91+meth. Car coming back to me at 420 to work bugs out. Hopefully we can get a solution from Eurodyne and move on to e85 tuning with a hope of reaching 500whp. In the meantime Dave says car is very quick, spools early and roasts the tires in 3rd gear.

.. Photos will continue to trickle in

decided to go all G-LOC brake pads f/r for track.

Waiting :)

Wow looks impressive, waiting for pictures!

Props to you for going all out with this platform, and thanks for sharing it with the community!

How much psi are you going to run?

I ask because I've been doing research on upgrading rods and I'm seeing in tuning communities of other brands (Subaru, Evo Etc) H beams are thought of as insufficient when running lots of boost. Most of the 500hp+ guys are using I beams (Eagle Turbotuff), similar to IE's Tuscan rods.

This was the approach I took...

I have a power goal of 450/450 ish. Keep in mind this is purpose built for track days and I want to be able to beat on it all day long. The EFR 7163 is a small frame turbo and it probably can be pushed to 500 but at the limit it will run very hot and for hours of constant road course work that is just asking for a major failure. I am not seeking max power but rather reliable power. H-Beam rods are good for handling a lot of torque and will be fine for my needs.

If I was going big frame turbo and 600-700hp that revved to 8K rpm I would go with I beams as tensile strength and weight savings really become important if you are making high hp at high rpm, where I am making most of my power well before 6500 and am more concerned with compressive forces that break the OEM rods. (torque) Forged rods, Calico bearings and ARP hardware should be all I need for what I am planning.

Anyway, the short of it is I decided on use and outcome I was looking for and built the motor accordingly.

I mostly used this great article put out by Integrated Engineering.

I'm so excited to see your project finishing up.

[GIACUser]

As per usual with this project it is one delay after another. There was an Aquamist cable missing from kit... so we are waiting for a new one.

Edit - AU sent email 10/19, part did arrive and they are working on finishing up the wiring.

Did you drive/test the car before installing the Aquamist?

[GIACUser]

No, it has not been tuned and the suspension was all bolted on but not adjusted or aligned (likely way off considering the mods)

So excited to see this car almost done I'm local and would love to get a ride if I could.

[GIACUser]

Of course, as soon as I get it dialed.

Well I was unable to get the Ohlins so I went with Eibach Multi Pro R1. I went through ECS for the Ohlins but they kept pushing back the ship dates so I eventually just asked for a refund.

I was ok with either choice. Wanted a quality Monotube with easy adjust. and I saved over 1000 dollars by finding this deal.

Usually they are about same price Ohlins about 2500 and R1 about 2300. I was browsing the Eibach clearance site this morning and they had both R1 and R2 at big discounts.

R1 - MSRP is 2441.00 Clearance Price is 1357.00

They also have R2 for sale which are remote reservoir separate comp and rebound adj.

R2 - MSRP is 3028.41 Clearance Price is 1857.70


These are really good deals - get em now if you are thinking about upgrading your suspension. Eibach Closeout LINK

The R2 looks awesome, and only $500 differences.

Holy shit, wish I had a spare $1800 lying around right about now. A second set of R2s would be awesome (no down time when sent out for rebuild).

So why didnt you go R2 at that price?

Yeah, I thought about it but the R1 are essentially same just no individual control of rebound and compression. R1s will be all I need for my street/track usage. I still have enough control options between swapping out springs and the single control.

Many other expenses all at once, remodeling a couple of our bathrooms and my TV got killed during demolition so of course I had to replace it immediately 75in 4K QLED bunch of money going out all at once, had to try and please the wife by making a cut somewhere.

[GIACUser]

Picked up the R1s at Will Call today.
They look great, top quality.

You're going to love em!

That is what I am hoping. They are so cheap I may buy a second set. (not really)

Lol, that's how I feel about the R2s right now. Considering they were just shy of $4k when i got em, at under $2k that's a hard thing not to buy.
