This isn't exactly a z, but it's a datsun at least.

This guy has a carbureted ka24. I didn't even know that could be done. Is doing something like this a simple bolt on thing or did this guy have to fab up some sort of an adapter to install weber carbs on his engine. I'm really interested, because this guy is able to drop in a more modern engine into his car without having to worry about installing a whole wiring harness and ecu. Right?

looks like he or someone fabbed those adapters up. the welds dont look that great. but hey, if it works . . . .

ya, I emailed the owner. He said he just cut the stock manifold and welded the carb flanges to the manifold He doesn't have a wiring hatness or ecu. He said he did it so he can easily tune the car without having to mess with the ecu and to be more original. He also sid he had to make a distributor for the engine.

I have no clue as to how someone would make a distributor for the engine though

One way is to take the electronics out of the stock distributor for the KA and installing an aftermarket kit like what Crane offers for the ZX. That way the Crane unit controls the ignition and you don't need a ecu to do it. That's how I would've done it. If he fabbed an entire distributor though, then dudes got skills.

Captain caveman

so that crane unit you're talking. Is that what people use when they convert their l28s to carbureted. Is there more that has to be done. Like the ignition or any other electrical, or does all of that stuff work indepedent from the ecu?

The only thing the ecu contols or receives a signal from are parts related to engine control )i.e. sensors, injectors, etc.). So you can just rip out all the wiring accociated with the ecu if switching to carburation. The only thing you would then need to wire up is the ignition which is a walk in the park on these older cars. You could just wire in the Crane unit running it from your existing ignition switch and voila! Carburated L28. I also beleive you will have to run an electric fuel pump, but not the FI one, way too much pressure for a carbureted vehicle!! Which would also be wired to your ignition switch.

Captain caveman

where do you find these crane units at?

Victoria British has them.

MSA has them as well. I've tried a couple local speedshops when I lived in Cali, but they both told me the same thing. That the manufacturer isn't producing them at the time and doesn't have any in stock. So maybe MSA and VB just have a bunch stockpiled or something? I don't know. I
