Well, the owner is RAREW66 on the forum. But GM designed this, its a concept car he bought at auction from a museum.

Pricey at $2400 but curious how this would integrate? I'm kicking around the idea of an SD4 or some bolt on SD4 pieces, still researching and learning about the engine.

I'd do a MSII or III before I handed over 2400.oo for tbi

I know a member of the Michigan Fiero Club who has a 3.0 liter 2 valve Super Duty engine in his car and he has had port injection on it for at least the past 20 years (as long as I've known him). His engine had a carb intake that was cast with bosses for port injection which he had to have machined so that he could install injectors. Where the carb would mount there was a 90° elbow that was made for the intake and that elbow had a mounting flange for a twin butterfly TPI style throttle body. The throttle body was in a horizontal position. |

Sounds like this one...

Nice! I like it.
I ended up owning the SD4 Automoda that was posted above, for a few months.
The carbs (Dellortos... not Webers) were whacked (probably from 20+ years of sitting, and seldom being driven.)
I ended up removing them and installing a 2 barrel Holley carb. The plan was to rebuild the Dellortos, but I ended up selling the car.
With that said, I recently bought an 88 coupe with a Duke. I wouldn't mind bolting on an iron SD head (don't really need the "maximum effort" aluminum head) and adapting a 5.0 or 5.7 2 barrel TBI, and seeing what happens. (Would have liked to do that with the Automoda/SD4, but every vestige of computer control had been eliminated. Would have had to reinvent the wheel, to make it happen. Just wasn't worth the effort to me.)
This car was bought with a swap in mind, anyway. If the Duke self-destructs, I'd just sell the head and continue on with my swap plans.[This message has been edited by Raydar (edited 05-28-2016).]

Your car has been an ongoing source of inspiration for me. You made all of this stuff work, and apparently it works well.
With that said, I ended up receiving an offer that I couldn't refuse for a 96-97 LQ1 that's damned near ready to bolt in. Unless something changes, that's what's going to take up residence in my coupe.
(But I still miss that SD4.)[This message has been edited by Raydar (edited 04-26-2020).]

Indirectly, these two are the same post.
Triggering is always the big deal with EFI. Throttle bodies and injector mounting are typically straightforward.
The Fiero 2.5 distributor has the pickup coil & HEI module (isn't it HEI?) that produces a 1 trigger pulse per ignition event signal to the ECU of your choice. The Quad 4 and later 2.4 engines use the same 6+1 crank wheel as the 60 degree V6's. A more modern crank sensor setup from the later '90's/early '00's 2.2 pushrod engine MAY be quicker to adapt to the SD4 than anything else except the EFI Duke distributor.

Thank you!
It is very driveable in city/highway driving and gets 30 mpg on the highway.  [This message has been edited by fierosound (edited 04-28-2020).]
