I bought this car back in August 2009

It was ok. The wheels were bent, was completely stock & generally boring.
So I began to strip it

I bought the metal front end from a parts importer. To say a metal front end is hard to come by in the US ( I'm from Ireland ) is an understatement. Eventually I had to settle for what essentially looked like it had been dug out of the ground. But that was nothing a huge amount of labor couldn't fix.
I got the headlights, brackets, grill and front / back bumpers / brackets and all service items from a local dealer.

Had Hasselgren build me a really nice 20v. 200bhp, 130lbs. 9,000rpm. The problem was that I spent too much time around their 16v Atlantics & decided I had to have one. Sold the 20v, saved & bought an engine from them.

Also, my exhaust manifold for the 16v arrived today. I couldn't be happier with it. Because the collector is so big it meant that it had to be a very high rise manifold to start the collector as high as possible before it gets to the steering.

Got a nice surprise, the chassis arrived back from being adapted for the Omega dash & wheel speed sensor. When it was 1st made it was a generic chassis harness. Since I was sending it back to be modified I decided I would have it tailoured for the actual car so all of the lenghts are now correct. The ECU will live in the glove box & that was used as a reference for the lenghts of the rest of the harness.
I knew I was dealing with a competition level shop but really was sure of that when the emailed me the PDF pin-outs of every connector as well as the layout diagram for installation reference.
The pics are just print screens & in the PDFs you can zoom in to see each individual pin in the connectors....

Engine bay sanded and washed, ready for paint next week.
Put one mount on the engine only to find the intake side mount doesn't fit with the oil pump. Out came the angle grinder, plugged in the mill and went to work. Put the amount on a bit of a diet and it's in. Pics once painted.
Put in the adapter plate for the gearbox. Will do a test fit of the box over the weekend and maybe make the gearbox mount next week. Always hated that battery tray. Glad to have it gone...

Mount finished: I have bought another one so I can take the measurements & make a much cleaner one to be the end product. The new one will be all done on the mill & the bottom right mount hole will be a bit thicker. Approx. 4mm

Taka's solution:

https://www.6speedonline.com/forums/...ine=1400865726[/url]

Remove the brake booster & bought this. Always hated the look of that booster !

https://i927.photobucket.com/albums/...psef769d5b.jpg[/url]

Now that I knew that the 1st modified mount worked I set to work doing a 2nd one only with a mind to keep this one as the mount that will stay with the engine. I marked it out, milled the forward most hole properly and made the reliefs with as little material removal as possible. Ended up with just about 2mm of clearance in some places. Also made sure to have all rounded edges to try to prevent cracking.

Finally decided on a clocked position for the oil tank & had the base welded to it.
All of my oil circuit connectors showed up. now just waiting for the hose.....
Also picked up a set of sticker slicks for when I install my 13x8 & 13x10 wheels. Will look into cutting thread into them when I'm ready to install them. Already have the thread cutter...
Finally decided how and where the oil lines are going. Modified the rear seat to allow the lines to pass underneath it and still look stock. The goal is for it not be obvious how the dry sump system is laid out once the interior is back in and the trunk privacy cover is back on.
Put my 1st AN fitting together today as well. Wasn't as difficult as I thought it would be. Once I started on the 2nd one it was easy.

When I got the carbon seat I found the alcantara coming away from the fiberglass seat cushions. Not being happy with that I removed the cushions from the seat. I came to find out that the early seats that Tillett made had the fiberglass backing glued to the carbon rather that taped like the late seats. This meant that both cushions broke during removal. I sanded both cushion backs & repaired the cracked sections with some carbon scraps I have in the garage.

Well today I finished the valve cover breather as well as the breather tank and vent for the oil tank. Instead of the tank breathing to the atmosphere ( into the boot / cabin ) I used a household brass barb mounted to a carbon plate that replaces the standard body plug in the wheel well. The catch tank breathes to atmosphere through the well floor exit.
Also made a very brief start on the exhaust system. 1st mount measured, bent and ready for tacking.
Lastly, removed, painted & reinstalled the gearbox mounts. Also mounted my new driveshaft.
Next week will be all exhaust.....
