fb 13b engine in s4
i have a streetport 13b that was pulled out of a 83 gsl. i've searched like crazy and cant find any info.i want to put it in my 87 gxl but im not sure what i need to adjust to make it work. it has a distributor in it right now but not sure if i can put the gxl ignition system. im not sure if its a gslse engine or a s4 engine. also do i need to change the counter weights from fb to fc

FB mounts are completely different, there is no oil injector bosses on the rotor housings and the center iron will not accept the FC lower fuel rail(GSL-SE only had 2 injectors). i also don't believe the FC lower intake manifold will bolt to an SE block.
so it would take alot of fabrication to make it work, not worth the effort IMO for a lower compression engine with heavier rotors, inferior chroming on the rotor housings and lack of nitriting on the iron faces. the only real pro to the engine is the coolant seals reside in the rotor housings versus the irons which have a tendency to fail in later 13B engines.

what do you mean by direct injection? never really paid much attention to where in the runners they were located as they would have to be further up the intake runners i would think(no one actually pays to fix FBs so my knowledge is limited). i also could have sworn the rotor housings did not have ports for the oil jets, are you sure it is a GSL-SE engine?

"The gasoline is highly pressurized, and injected via a common rail fuel line directly into the combustion chamber of each cylinder, as opposed to conventional multi-point fuel injection that happens in the intake tract, or cylinder port."
From http://en.wikipedia.org/wiki/Gasoline_direct_injection
I doubt a car that is 30 years old got common rail xD

no, it is port fuel injection if you compare it to piston engine terminology. they also referred to it as "the combustion chamber of each cylinder", durr there is no cylinders so i wouldn't even take most of what was said seriously. the injectors are in the intake manifold, not the rotor housing which would then be called direct injection which they are toying with on the 16X engine.
at any rate, i'm sure it is possible to make it work but the non turbo FC 13B engines aren't that difficult to find yet that an engine swap, modifying intake manifolds, replacing timing cover, water pump, etc, etc, etc. would all require.

If it has injectors located on the intake manifold, it's one of two things:
1) A complete S4 engine
2) An '84-'85 GSL-SE engine with a an S4+ intake manifold frankenstein'd on
The GSL-SE used only two 680cc injectors, and they were located on the top of the block. No injectors on the manifold.

I did this same exact thing in my car for a while. You have to fabricate some decent mounts, and not just throw something on there. I never solved this problem and had to keep fixing and re-welding them. It wasn't worth it in the long run. I'd try to trade the engine in for something that will be a better fit.

Take a picture of the engine, I have a GSL-SE keg in my shed and an S4 in the driveway.
The 1983 model did not come with a 13B, so it's definitely added in. Being that the GSL-SE is rarer in the scrapyard compared to the N/A S4, I'm leaning toward S4.
The bare keg of the S3 and S4 13B engines is not that different.
They both have the same compression ratio, but the rotor weight is lighter on the S4 by 1.5 lbs.
The S3 has 3mm apex seals, the S4 has 2mm.
They both share oil injection components according to Mazdatrix; Same OMP and same injectors on the rotor housings and intake manifold for 1984-1988.
I'd wager the engine will match what manifolds are on it.
Take a pic of the engine; Just get an overall view for now. I'll tell you if I need to see some detailed stuff.
