This was one of my favorite turbo projects of a few years ago inside and out. A couple of years on from her original EVT700 build this car came back to us for a hardware and software update with EVOMS' latest EVT775 upgrade, including the dual-mode ECU for 91/100 octane (the switch is hidden in the ashtray). Since then she's also added a set of TechArt GT Street Side Skirts and all-black 19 inch HRE 893R wheels.

Off comes the bumper..


From the other side you can see a few suspension goodies including the TechArt coil over kit and many solid links/bushings.


And the Tubi Race Exhaust system:


The parts start to come off..



Out comes the airbox and standard throttle body:


The factory plenum vs the larger Werks1 T-pipe kit:


Werks1 Kit installed in order to accept the larger 82mm throttle body kit:


The factory inlet ducts are indeed quite skinny/restrictive and to feed the upgraded VTG turbos we installed the EVOMS Turbo inlet duct kit (driver's side shown):


And installed:


And other side:


The smaller 997TT throttle body (left) vs the larger 997GT3 throttle body (right) ready to be installed:


The stock pulley is also removed:



And the EVOMS lightweight pulley kit installed in its place:


A box of take-offs including the stock coil packs, throttle body, plenum etc... These were all replaced with EVOMS' HED Coil Pack kit and upgraded spark plugs:


James installing everything back together:


Here we are with the ECU/DME open and installing the necessary EPROMS for two fully-functioning ECUs. The EVOMSit software is then burned to each EPROM.


A switch was run to the center console ashtray for 91 or 100 octane modes:


Ready to go for a test drive:


Ready for pick up...

 

No dyno posts?

 

TestJet! We need some impressions!

 

It's built in exactly the same fashion that we've been doing since late last year when EVOMS live-tuned the kit on another of our customer's cars so with all the hardware staying the same etc...

Felt very good to me on 91

 

plenum + ducts + throttle body = 75 more hp? not that i need it, anything like this for 996?

- chuck

 

+ new tune

 

There's a few lil' things that have come up... we can chat tomorrow but it would need to be tuned for it
Bingoz!

 

Very nice!!! Looks great!

 

Love the EVT 700 to 775 upgrade. Small items that go a long way regarding HP increase. Lets not forget (EVOMSit tuning) the icing on the cake.

 

Cheers man... they look good in white
Cheers pal.. It scoots well!
