965 3.3 : Electronic Fuel Injection (EFI)
Hi,
i'm a french owner of a 1992 964 TURBO 3.3, and i would like to show you my EFI project, nearly finished after 3 months of hard work. I just need to opimize my MAP because i'm using a simple lambda sensor instead of wideband lambda sensor... So i'm waiting for ~520HP with great MAP (at 1.1bar).
But actually, with a bad AFR of ~9/10, my engine has got 471HP and 645Nm (at 0.9bar), you can see below pictures of my project :
My 965 :
And power/torque here : (before and after EFI)
Sorry in advance for my poor english, and please.... speak slowly

Thank you onboost, the ECU is a Sybele Commander44 from skynam, you can see more informations here :

It was not a good choice because we are the first to use it ! A lot of time spend to understand this ECU and some bugs like with all new product... but now it's ok

EFI hardware (~$3500), there are EFI injector block package with fuels rails and sensors.
I've got too a manifold extrude hone, open ports to 40mm with cylinder head insulator blocks tapered bore down to 32mm (40>32).
I've got a GT35 turbocharger from garrett (ball bearing), headers from GoingSuperFast and a HKS super sequential blow off valve (nice sound !!).
It's not the standard intercooler, i've got this one from blownsix : http://www.blownsixdesign.com/new/965.html
