Modern FI is definitely the way to go. Unfortunately it's not smog legal in most places. If it is legal, a good modern FI is the best solution.

Begin rant...Non-directional flaming imminent...Please take no offense....

I'm no smog expert, but what's the logic in making an updated FI system smog-illegal? Up-to-date FI is cleaner-burning than original, and puts out lower emissions, not to mention better power!!!

Here in NC, one can put in replacement engines, provided they are "newer" than the body...One could then put a 280ZX engine in a 280Z with no problems, so where's the difference between that and swapping out the 25-year L-jetronic and replacing it with a more modern system????

Of course, since 1972 and older 240s are 35+ years, the state emissions and inspections don't care to see 'em in the inspection stations anymore so we can do with them as we please...in a few years the 280Zs will be there too...

I know, I know...it's a rhetorical question. No flaming intended. Just makes me mad when states make it illegal to update our old cars to be cleaner, more efficient sytems....

End rant.

I'd be willing to badmouth the factory FI. Let's see...

That's fair. You're 'bad mouthing' it for the right reasons.

For a brief write-up on a 3.0 litre with FI check out http://www.tizcc.ca/tech2.htm and http://www.cardomain.com/ride/566675/1

What isn't explained is the work he put into building the fuel injection system, and that he chose to build the FI after dealing with 3 webers. He's since gone to the V8 side (another lost...)

So if I was to swap my l26 for an l28 and use my roundtops would this run better and have more power then if i kept the EFI?
