I was hoping this was going to be a bolt-on affair, with just new 4" piping needing to be fabricated......right....
The new turbo hit the valve covers, so Jason @Matchless Performance came to the rescue to modify the exhaust manifold.
The block looks so lonely without it's friend.
Starting the modification work on the manifold, basically changing the angle on the flange so the turbo sits flush.
So now....the actions shots...

Man, Jason knows how to work by the clock. Took right at 3 hours from start to finish, very impressive.
Look at the clearance....Almost makes me want to go bigger, hum....

Sorry for the dusty valve cover shots, I'll get some better ones this week.
Here is the completed engine photos showing the new Borg Warner 74mm ETT Turbo.
We put the car on the dyno this weekend, special thanks again to Chris Hamilton for the tuning. You truly are amazing.

At 18 PSI (593whp), the car ran out of fuel, and we found the problem to be a dead Walbro Fuel Pump. We'll be going back this weekend to retune for 25 PSI, expecting around 750whp.
Then onto the C16, where we will shoot for 900whp.

Update:
Went back to the dyno this weekend with new fuel pumps, and ran into our next problem, maxing out the 1000cc injectors at 624whp/442tq.
1600cc injectors are being installed this week, and we'll head back to the dyno for round three, haha.
The E85 really requires big injectors, and I never imagined we would max out the fuel system this quickly. Im guessing we're going to end up with a Weldon Race pump, as the dual walbro's are really struggling to keep up.
Enjoy the Vid!
