Is there any sort of aftermarket fuel injection chip for a 78? I know there is one for the later models. Also, is there much of a choice for new injectors?........as it pertains to more power. Maybe a couple silly questions, but any advice would be great!

Eventually I would like to rebuild the stock L28 motor on my 78. There are some performance mods I would like to consider like a lighter flywheel, cams, maybe a bigger throtttle, headers, etc. However, I am trying to stay away from anything like throwing in a turbo, nitrous, or swapping out for a V8. Mind you, all those are exciting mods, but they are just not for me. My attempt is to get the most power out of that staight-six without going over the top. I am asking 4 things: 1. What upgrades are recommended from you guys? 2. Is it possible to get the car in the 5 second range (0-60) by doing it this way? 3. What is the calculated top speed? 4. What's the most horsepower I could get? Thanks!

I would suggest using a higher viscosity oil like 20W-50 since it's an older engine. If you can afford synthetic, even better. But for those of us that don't want to pay more than $20 for changing their own oil I would stick with Castrol, Valvoline, and even Quaker State to save a couple bucks. I use a Bosch oli filter. However, I'm not sure if it's any better than your typical Fram filter. Yeah, another great thing is to drive the car without the cap screwed onto the can cover. Did that once. hehehehe. j/k.

Yeah, that's where it seems to start. But even in the lower RPM's I can still hear it....sometimes. What do you think? Thanks!

I just had my garage install the MSA turbo muffler on my 78 280. Although it doesn't have the headers yet, and the catlyctic convertor is still on, the muffler sounds great. However I will sometimes hear a vibrating sound....Almost like a slight rattle. I checked their work and everything seems fine. I called up my trusted mecahnic (great guy) and he told me that this was a normal sound for the MSA muffler due to its "tinny" nature. However, he said in time that sound should go away. I'm not sure what is going on, but I sure hope that it does go away. I'm not sure if it is a resonance due to the construction of the muffler, or it IS rattling. Any thoughts?

Maybe I should find out how to submit some more Z sightings. For example, how about the red 280ZX in Boogie Nights? Or the gold 280Z in Annie Hall driven by the main character? I remember seeing Annie Hall in my film class and cheering to myself when she pulled out with the Z.

Hmmm....I had the same troubles from a full dashcap I purchased from Motorsport Auto. It was for my 78 280. Well, what I did was I took it back and exchanged it for a the half-cap cover. It may not look as authentic as the full-face version but it does a remarkable job in hiding those cracks and improving the look of your interior. It's so much easier to install and costs about half as much. Just be sure that your unscrewing the panel right in front of the windshield so that you can tuck the lip of the dashcap under it. This will help secure the cover. Hope this was helpful.
