924 Turbo With V8 Fuel Distributor, FMIC, & Hybrid K26..

Turbo and FMIC from a previous tune stage..

I'm working on getting the V8 distributor install finished up now with supporting tuning electronics, MicroSquirt, FrankenCIS..

It all still keeps the factory popup headlights, washer tank, intake, upper and lower charge tubes and airbox and my CAI/ram. Still looks very factory and very little body mods..
The only real difference you will be able to see under the hood is a BOV, the new fuel distributor and intake boot to airbox..


This is with the IC and turbo done just before the FD install, just the BOV is unoriginal, and now the FD will be too..

It will stay narrowbody and original interior mostly, some brake upgrades done too..

Wow. Lots of ingenuity in your build.

You know, I had been wondering why I hadn't seen that tried before. Seems like a relatively easy way to "double" fuel capacity on the CIS system.

Cool car...

"double" is about right..
It would be much easier if I weren't trying to keep original components such as the pop up lights and washer tank and stuff..
924 turbochargers have big bulky compressor housings that really limit your positioning options, but I found that going with a hybrid, more normal compressor, you can turn the thing right upside down and shoot the compressed air out the bottom of the car instead of towards the top, so I was able to route all of my intake IC plumbing on the bottom side of the car by the sway bar rather than under the hood where their is no space and usually requires removal of the pop up lights mechanism, washer tank, things like that..
So I ended up with an intake that looks like this..

Right back to where the OEM intake would directly attach to the turbocharger as standard..
See the difference in compressor housings.. They have an integrated recirculating BOV built into the compressor housing, I'm pretty sure the 931 BOV parts are the same as the 930 BOV parts that are in their intake rather than compressor..

I do really like the monster OEM BOVs though so I have thought about modifying a 931 compressor housing's intake port so it can be flipped upside down like a standard compressor housing can. Maybe some day, but I'm not sure one could be bored out for a big enough compressor wheel for real power..

As far as the V8 CIS, the only way I found to get it in there and not have to start chopping or throwing out OEM components was to make a custom adaptor flange from the V8 distriutor's upper air housing to the OEM 931 lower air housing, so it will mount exactly the same in the same place as the original FD and AFM on the same mounts and have the same plumbing path..

That piece turned out to be a whole lot more work and time that I originally thought, pretty much hand made, but it worked out.. Until it was finished I really had no way to know if it would really fit or if I could find a way to plumb it so I was nervous about all that work for something that might not work but I was lucky and it worked out..
I did have to but a little 1" dent in my wheel well though for it to clear, I really don't like doing that kind of thing but in this case it was worth it..

The only other bad thing I had to do to the body was some small cuts where the FMIC 3" outlets are.. I think if I would have had an IC with 2.5" outlets I may not have had to cut anything at all..

I moved the bottom of the radiator back a bit and the top of the radiator forward a bit for room and it turned out pretty nice IMO..

It is quite thick..

I guess I had to cut the backside of the tow hook mount a bit too but not enough to weaken it..

I'm pretty happy with it and highly recommend this method if IC install on a 931..

If I can get enough fuel and tunability to properly feed her now she should scoot along quite nicely.. Fresh OEM HG and ARPs just done too..
I think I'll be able to tune it to 300-350 HP like this and maybe some day with a bigger yet compressor and different pistons I can maybe get 450 but will likely also need a radiator upgrade somewhere in the 300+ range..
The OEM radiator seems fine so far to somewhere around 250-275HP where it was running before I started the fuel distributor upgrade..

I have a good LSD G31 trans so it should be plenty to handle anything I can hope to get out of a 2.0 but I really need more tire.. I hope to find a good deal on wider 928 gullydeckle wheels some time so I can run a bit more rubber..

I'm running fixed 4 opposed piston front calipers but I have to install my adjustable brake bias valve, incabin, and reroute my lines to F/R split before I can do up the rears.. Kinda just got to get around to it..

The setup is running well!!
Keep an eye on my youtube channel for updates, videos are just easier..
