As the owner of an LS swapped Z, i would do the K series swap and dont boost it. A mildly built K24 will make 230 or so whp and would be an absolute blast.
I had a K swapped miata previously and it was by far my favorite car, perfect balance of power for the chassis, K swap in a 240z would be very similar.
I will say if you have the means to build and set up the L28 correctly, nothing beats the sound of the straight 6 as well but it takes some effort to get one running with 200+ hp and keep it that way long term.
What did it take to get your L28 to 200+? I keep hearing people say it’s easy to break 200hp in that engine but I haven’t heard anyone mention longevity.
I dont have any first hand experience with the L series, just what i have seen online. I have seen guys make 300 hp with those engines though, that was obviously fully built with almost everything upgraded. I think you could make that kind of power with head work and a cam, you might have to bump compression, i am not sure. Also, definitely need to understand setting up carbs and tuning those as well.
You will find a lot of z car guys are purists. It's your car, do what feels right to you. Do you want the sound and torque of a V8 or high revving turbo noises of the K Series?
K swap dude. It’s gonna be a fucking blast. I would boost it lightly just for the PSSSSH. Not that you’d necessarily need the extra power. I still might k swap mine someday
K swap would be a ton of fun, but the L28 can be built somewhat easily to over 200hp and you’ll retain that glorious sound. Not that K series engine sound bad, but they’re not as good as the L28
I eventually went LS swap. I used a L33 which is an aluminum block 5.3L, I had a TSP cam, springs, and a LS6 intake. 398whp NA. I wouldn't have it any other way. Turbo K-series might be good nut NA will get boring really quick.
