1100 D Station Wagon I posted a description and some photos at "Member's Rides". Post title: Subwat

I've had some requests for pics of my ride, I'll describe it and attach photos. The body is a 65 Fiat 1100D station wagon. I got it with the engine out but put it together. When the Fiat engine got tired, I didn't want to rebuild it so I bought a VW Squareback cheap. I tore out the whole Fiat drive train (front engine rear wheel drive) and put the VW subframe, transaxle and engine under the rear of the Fiat. I built a gas tank and put it in the ex engine compartment. I ran the car that way for quite a while but I didn't like the VW engines. I heard that some of the VW guys were putting Subie engines in their cars/vans. I bought a used 83 GL wagon with a 1.8 EA-81 engine, bought an engine adapter kit from KEP, and did the swap. That Subie engine is tough, I pulled it (still running strong) when it had over 300,000. Current engine is an 84 1.8 EA-81 Turbo. I got it used from an engine dealer. The engine was complete (all accessories etc) but no wiring harness or computer. I couldn't locate a computer so I went with a MegaSquirt computer kit. This car is my daily driver (except when I'm swapping engines lol). I'm currently fine tuning the engine (done with a laptop computer.)

Ok Gang, Here's what's going on. There are 2 types of injectors (any car) high impedance (Hi Z) or low impedance (Lo Z). Hi Z injectors will measure about 12 to 16 ohms, Lo Z injectors measure about 2.5 ohms or less. Measure this with your ohm meter. Hi Z injectors don't need resistors, Lo Z need resistors or a circuit called peak and hold (full current to open injector, then less current to hold it open). My injectors are Lo Z (2.4 ohms) and needed 10 ohms to limit the current. The resistors go on the power (plus) side and the ECU switches the ground. If you fire more than one injector at a time, you need one resistor for each of the injectors that fire together. I believe the EA-81T was bank fire and fired the injectors in pairs. I'm running sequential fire (each injector separate). I don't know what the factory was doing at any particular year or model, but my injectors are Lo Z. I bought the engine used (it was complete) but I never saw the car it came from (engine might have been pulled from a car in Japan). I never saw the wiring harness or computer and couldn't locate a computer for the engine. I built a computer from a kit (MegaSquirt) and I drive this engine daily (it's in a 65 Fiat). i'm still working on getting the best tune for the engine.

To set the record straight: My injectors did require resistors. 10 ohms 25 watts does the job (don't know if this is factory specs but it works fine in my application).

Turbosubarubrat, Many thanks! just what I need to know.

Thanks Crazyeights, The injectors are rebuilt, but the rebuilder says it's off company policy to give out injector info. I'll check with Dr injector and see if I can learn anything.

I need to know the injector size for an 84 EA-81 MPFI turbo engine. This is in cc's and is needed to set my fuel tables. Anyone know this or how to find out? Bob

Thanks Naru!!

I've got an 84 EA-81 1.8L MPFI turbo engine. My manual shows a dropping resistor that the injectors connect to. I need: either a service-able dropping resistor, or the resistance (and wattage) so I can put something together to run the injectors without frying them. Thanks, Bob

Hi to the USMB gang. You can consider me an old school hot rodder. I've been running an 83 EA-81 1.8 pushrod engine in a 65 Fiat 1100 station wagon. The engine is in the rear mated to a VW Squareback transaxle and rear suspension. Recently, I bought a used 84 MPFI turbo engine, which is replacing the 83 (the 83 while still running strong, was getting a bit tired after well over 300,000). I'll be looking for info and maybe a few parts. Bob
