Engine and tranny have met for the last time. Superstructure is complete. Working in getting (you are not going to believe this) the wiring harness STILL, getting the details squared away for the front engine mount(this is a hybrid engine/tranny combo and the mount is somewhere in between), put a Audi TT 225hp intake manifold on and am getting the bracketry around it squared away. There is now a nice straight shot from the turbo outlet to the TT intake, about the distance a good A/W intercooler(chargecooler for the guys on the other side of the pond) should fit nicely into. The clutch might be a hybrid as well for now, stock type I cable back to a bracket that moves the hydrolic master cylinder for the stock Jetta. Eventually I'm sure it will be hydrolic all the way, the trouble is getting the pedal assembly in there without too much cutting. I was not able to integrate the "pendulum" style mounts of VWs from 1998-present. There was not enough room for clearance on the passenger side of the engine without cutting out the inside of the passenger rear wheelwell. I think I can make the oldstyle low mounts work, I just don't like the amount of engine/tranny movement that they allow. I'll probably build some additional motor mounts to prevent unwanted movement later. The biggest hurdle currently is how to attach the upper strut plates for the Mac struts. If they are welded on, to remove the superstructure from the vehicle would require the removal of much of the C pillar. I'm trying to come up with a way to make those plates removable so they can be unbolted then the superstructure will slide right out. That's it for now!

Bobtail,

Just want to say how sorry I was to hear the project had been sold. Like many others I was enthralled by your ideas- it was really an inspiration.

i am presently mocking up a mid-engine setup with double wishbones etc- and perhaps in another TEN years or so I might have a complete drivable car!!

Anyway- best of luck with all your current and future work

Chris, welcome to the nut house! Of course your going to have to keep us posted with your progress. Have you a digital camera?

Yep, I was very said when the Coopers said goodbye to the setup too. Does anyone know who has the car now?

Here's an old pic of the engine with the mock-up super-structure.

And this is a bit ago with the super-structure almost done.

Its a ROLLER! I set it down on its own 4 wheels this weekend. More details at http://www.germanlook.com/Forums/showth ... #post43910

I spent WAY too much time with the wiring harness. It looks like I'm going standalone! I called up 034 Motorsport and they are going to hook me up with a killer system. I like the idea of being able to tune it for the what I want it anyway, and this is a way easier system that uses most of the stock sensors.

I met a guy, Dave S, today. He is a member on GL Forums but hasn't posted yet. Keep your eyes open, it's going to get even crazier around here! Anyway, he had a DBW Mustang and said the throttle response sucked because of it, so I'm kind of glad to be getting rid of the DBW system. I'll be ordering up a cable throttle body tomorrow.

On the cooling front, I installed the bleed area up front. This is at the highest point of the front area of the cooling system. The valve can be opened when the pressure is up a bit in the system, and then any trapped air can be bled off.

Here's a pic of the rear end in its more or less complete form. Those are 4 piston Wilwood Dynalites. I'm thinking 6 piston up front, black again, and 13 inch rotors. I also have a mechanical brake caliper, but I'm going to have to fab up a bracket for that, it's not a bolt on type affair. Who needs an E brake anyway!

The hole for the strut was opened up a bit more than I would have liked, but it's all done in the name of science!

Just a little update: Cooling system is getting close to being done. Aluminum side cooling tubes are done, radiator is in place but not mounted. Brakes are coming together nicely. Have the Wilwood pedal assembly mounted, master cylinders and remote brake balance adjuster are on there way. Calipers are having logos machined and rotors are purchased. Hats for the rotors still have to be purchased, but offset measurements will dictate their offset. It's been pretty slow going lately, but I expect it to start getting going faster with in the next few weeks.

Well, a slow summer is yielding a fast fall. The brakes are now done and bled, clutch hydrolics are done and bled, cooling system is about %95 done, fuel system is complete. Waiting for 034 EFI harness, they say next week, need to pull the tranny, forgot a couple parts apparently, then wiring, and she should start!

Ooop, I've not been good at updating here, sorry!

Here's the latest little movie:

I worked on the shifter this weekend, it used to be able to slip into reverse as easily as 1st, so a little stop gives a positive position for the first/second plane. It's a little rudimentry, but simple and should work just fine for quite awhile and it's a screw so its adjustable.

How wide is your rear track? Outer tire edge to outer tire edge?

At the top of the tire or the bottom?
