  • was one of the fuzes for the injectors toast?

  • The injectors weren't firing, but it was only because they haven't been used in a while. They were cleaned and flow checked months prior to the first start.

  • what year and car did that motor come out of??

  • 94 Lumina euro 3.4

  • The engine has almost no mods, I run an Emulator in place of the chip for the time being. The 94 engine don't play well with my 5 speed. The exhaust ports and manifolds are ported to make them symmetrical, they are no longer "D" ports, they are "square". Did this to flip a front manifold to use it on the rear. I will post more vids over time, I just have to figure out what the latest bad noise is and fix it.

  • The exhaust is all 2.5" stainless mandrel bent with an off the shelf high flow cat, finished off with a Flowmaster 80 Series. It is the same layout as a stock Fiero. Just bigger.

  • I had a bone stock fiero gt and I loved that car. Yours sounds awesome!

  • Why can't I find any videos on the 3.4 pushrod swap?

  • @adamberg666 That is exactly what I was thinking. Sounds like you can hear air leaking or getting sucked really hard.

  • The engine that you installed in ur fiero was going to be put into the 89/90's fiero if they actually did come out. It was supposed to be the Quad 4 & the LQ1 in those.

    Too bad the Corvette guys in GM lost it, and got the Fiero cancelled.

  • sounds like a vacuum leak

  • its runnin really rich.
