hallo mede 924 eigenaren.
ik ben op een ander 924 forum gestuit op een ombouw van de motor.
http://www.924board.org/viewtopic.ph...r=asc&start=30
het blijkt mogelijk te zijn om de elektrisch geregelde inspuiting van een golf 2 GTI 1.8 8v zonder veel aanpassingen over te zetten op een 924 blok.
het ziet er allemaal niet al te moeilijk uit en veel geld kost het ook niet in principe.
nu is mijn vraag wat jullie hiervan vinden want zelf heb ik er wel interesse in aangezien hij dan zuiniger zou moeten en beter zou moeten kunnen lopen.
ik hoor het graag

I took the time to convert the word document over into a post so everybody can see what has been done. I for one think this is an awesome idea and effort. How about we as a community stop criticizing and try to offer suggestions. Maybe we have finally found a cheap way to upgrade our cars into the computer era. Thank You Ksis.
This is a brief over view of what I did. I will rip the system out, take pics and do a new install. That is how easy this was…
Let me begin by having you click this link
http://en.wikipedia.org/wiki/Digifant to get an understanding of how the Digi system works.
The below pic shows what sensor input is required to make the Digi system work.
-The distributor will be the unit from your donor car. The only modification you will need to make is to swap out the gear.
- The mass air sensor will come from you donor car. The only modification will be to purchase an adaptor from your local FAP to mount a conical air filter. Remember to include the plastic pipe from the donor car.
-The throttle body will be from the donor car. This is nice because it is a direct bolt on and the only modification is swapping out the cable linkage.
- The knock sensor will be from the donor car. The verdict is still out on the mounting location. I have not seen any difference in performance. I believe this is due to the low compression of the 2.0.
-The O2 is from your donor car and a direct bolt in. If you do not have a sensor, as I didn’t, a bung will need to be welded into the exhaust. I have not done this as of yet.
-The coolant sensor will again come from the donor vehicle. There are two options for the placement. I chose the latter, as I wanted to retain all of my original CIS components if I ever chose to sell the vehicle or replace it. The first option is to replace the sensor with that from a Subaru, any year or make as they are the same. They operate in the same range and will thread right into the location of the thermotime switch. The second option is to disconnect the bypass hose and insert the sensor directly in the hose and clamp. The only modification is to grind a small channel in the rim of the hose to accept the wires. I would say this is an unorthodox move, but if you think of a universal temp gauge, this is what they do.
-Idle air control valve. This will come from you donor car and will slip right into place with the use of 3/8 hose and a small brass adaptor on the throttle body hose where you cold air vale was.
- Fuel injectors are from the donor car and will use the o-rings from your old injectors. You will retain the original plastic inserts that are threaded into the head. I am currently looking into changes to get the injector farther into the head but this seems to work just fine. The fuel rail is you choice. I commited sin and used copper fittings. I did cannibalize a 98 SAAB turbo rail for the injector cups. There were easy to remove, as the SAAB rail was made of “COPPER” and had “BRASS” fitting brazed on….
-Fuel relay. Any four prong relay will work. This will be hooked to the only three wires that you will route into the cockpit. I will list the color coding and mounting later.
You can see the red/white, red and black/yellow wires from the harness.
-Hall control unit is from the donor car and will mount with the ECU on the driver’s side of the engine compartment by the windshield wiper motor.
Complete install. O
