We made a new smooth firewall with recessed pockets for the coil packs

Also needed to raise the trans tunnel so we just decided to make a new one with a removable front section......

Here is a link to the video of some of the dyno pulls.......
The videos make it look easier than it was - it took almost 100 pulls and 40gals of C16 to get it down. We didn't ring it all the way out as we didn't want to beat it up anymore before it made it into the car. These turbos will max out around 35psi so there is more power to come.
Disregard Tom's comment about it going into an Oldsmobile - it was late at night and he was delirious from getting his *** handed to him by all the "teething" issues that kept popping up.

It's been a while but in case anyone is still interested we are almost done with the fabrication stage of the build........
Seam sealed/primed firewall, Wilwood master cylinder, and steering linkage

DSide downpipe mockup
![](http://i1173.photobucket.com/albums/r600/TwinTurboGSx/Fabrication/file-3.jpg)
PSide downpipe mockup
![](http://i1173.photobucket.com/albums/r600/TwinTurboGSx/Fabrication/file-2.jpg)
3" to 3.5" transition from turbo (for future upgrades)
![](http://i1173.photobucket.com/albums/r600/TwinTurboGSx/Fabrication/file-4.jpg)
Transition from round to oval tubing
![](http://i1173.photobucket.com/albums/r600/TwinTurboGSx/Fabrication/file-7.jpg)
Borla mufflers
![](http://i1173.photobucket.com/albums/r600/TwinTurboGSx/Fabrication/file-12.jpg)
3.5" tubing over the rear (this was a major pain but it clears)
![](http://i1173.photobucket.com/albums/r600/TwinTurboGSx/Fabrication/file-9.jpg)
Overall the exhaust is tucked between the cage and the body - it won't even be visible unless you roll under the car
