So the story behind this car is that we wanted to have some fun and do something a little different. The car used to be my wife's car. As some of you know, the 12v V6 is a workhorse of an engine and very reliable. Nothing but the most reliable for our ladies, right!?

But in the late spring, she scored a great deal on a one year old Jetta GLI, so the light turned on in my head and I figured this would make a nice project car.

I started by putting in some Penske Racing coilovers...thanks for the help Tomasz at StartUpRacing!

Then, out with the V6:

In with a 4-cylinder turbo. Not your normal 1.8T or stroker swap here. We used a VW ABA bottom end (built with Scats and Wisecos), and a VW 16v head (build with supertech valves, HD springs, and Ti Retainers). Some European guys have been doing these swaps for a while. Also, think back to the racing days of B5 A4s with naturally aspirated 2.0L 16v engines. The Axis Motorsport tribute but with boost added:

We put an intake manifold together using the 16v flange and an AEB plenum and runners. Works like a charm:

One custom engine bracket (driver's side):

Intercooler (note the A/C delete):

I have to give credit where credit is due. I did not weld anything here. The fabricator, Jodi Doyle, did some awesome work throughout:

3" downpipe (remains 3" right to the rear muffler, then splits to twin 3.5" tips). Also featuring an exhaust manifold for a 16v longitudinal VW Parati made by SPA Turbo:

Modded rear head flange for -6AN fitting to bring water to the turbo:

Getting close...fab work is mostly done:

Here is how is stands today after completing an open track day at LimeRock. We logged 197.7 on-track miles that day. The street tune was set to about 14psi (it was about 2 weeks after first startup). However, in the last week or so, I turned up the boost and I have a pretty good street tune at 30psi. Intake temps remain under 40*C all the time when the car is moving. It will be tuned on a dyno next week.

Hope you guys like it!

 

Thats nice like too see her running or Dyno numbers :-)

 

Oops the last pictures and data didn't show up till my second peek. Very impressive.

 

Sure we do. Sweet project.

 

Awesome project! Wish I had the time and knowhow to pull that off.

 

I has 'JPG' instead of 'jpg'. Never knew that made a difference!

Anyway, we will be cleaning up the tune on the dyno next week, but based on previous tunes, i feel that we are pretty close to the max for this turbo now. I'll report back for sure!

 

Laser FTW. ;-)

 

nice...i thought the 12v's came w/ euro trunk lids...anyway the work looks top notch!

 

Thanks. I'm sure any K04'd S4 is still faster, though.
