EFI bolt-on & plug-in kit for the 924NA, 924SC and 931 (924 turbo).
I've worked on a set of parts that will allow to convert the 924 to EFI, but keep all the CIS components in place and partially re-use them.
The idea is absolute bolt on, plug in, start and drive, 100% reversible.
So no wires to solder, no wires to split into.
Around 100 sets delivered so far, along the supercharger kits being enjoyed in places like New York, California and other places in USA, Canada, Brisbane, Sweden, Denmark, Holland, UK, Spain, Czech Republic, Belgium and Romania.
Bespoke tune (maps) are available for your specific application, NA/SC/turbo
All the sensors and other EFI specific components will be bolt on to the old system and will stay as hidden as possible.
The "cherry on top" is the fact that this system wont use a conventional fuel rail.
Rather a replica of the original fuel distributor block acting as a fuel rail (block).
You get a set of new fuel lines as well.
Aim is: you open the bonnet, you spend 2-3h bolting on parts and connecting electrical connectors, you close the bonnet and you start driving.
Keep all work under the bonnet and installation time around a few hours.
End result is the engine bay looks nearly identical to the original but runs a modern system.
This should bump the power and torque up, improve reliability and driveability..no hot/cold start issues...smoother engine, more power.
Maps developed on the dyno and refined for drivability on actual cars, being driven on a daily basis.
For the 931S2, everything is already on the car, but for the 924NA/SC or the 931S1, the throttle body needs to be upgraded for this conversion, you need the TB from the Audi C4, reference part number: 048063D , 037907385H

IMPORTANT NOTE for the 924NA and 924SC:
The injector straps are coded, they are not all 4 identical.
1 hole coded straps are for cyl 1 and cyl2, 2 hole coded straps are for cyl 3 and cyl4.
This is because the casting on the 924NA manifolds is different between cyl1,2 and 3,4.
924 turbo straps are all 4 identical.
IMPORTANT: for 931, 924 turbo ONLY, the fuel block in/out ports are described below:

DISCLAIMER:
What the kit will not do:
-guarantee a power increase (this is highly dependent on many factors like conditrion of engine, fuel, your altitude and position on globe, etc..)
-turn your car into a race car
-make your car fast
-be legal
-make your car more fuel efficient
What the kit will do:
-give you a good time playing lego with your 924 if you're into that kind of stuff
-probably make you curse me for the more difficult part of the assembly
-enhance the driving experience with an oldschool flavor
-make your car start in every condition, hot or cold
-make you smile every time you drive your 924
Risks:
-this stuff is not a homologated and legal product, its up to you what you do with it, i just send you a box of parts.
-you can damage your engine if you mess with the tune or run anything but premium gasoline
-you can set fire to your car if you dont tighten and check for fuel leaks after the conversion
-literally anything bad can happen so keep your eyes open and your brain engaged, i just send you a box of prototypes, nothing is guaranteed, think and act accordingly!
