I’ve been restoring a 240z in my garage, it’s on a rotisserie…
Got a l28 turbo waiting to be refreshed as well.
I should stop working on this refactor and go work on it.
Nismo is coming out with a new DOHC head for the car... https://japanesenostalgiccar.com/nismo-dohc-nissan-datsun-l-...
There was also this gent who made his own DOHC off of a Honda head.

Don't forget the OS Giken TC24-B1 from 1976: https://japanesenostalgiccar.com/sema-2009-os-giken-tc24-b1-...
ISTR that Speedhunters made a gear-driven DOHC head for it.
I'm disappointed you went with FI, the L28 is wonderful, if I was you I'd be tempted to swap the EFI for carbs, I expect the carbs for the L's 24 and 26 would suit?
Any word on how much the Nismo head will be, the OS Giken one is absolutely eye-watering.
The estimation for the Nismo head is ~$25k for just the head, not sure if that price included the valve train as well... Derrick's head is ballpark the same cost.
There is one more company in japan JMC,that is making heads as well, they have a recast of the N42 heads w/ better machining. https://party-k.co.jp/used/index-3536.html
I have a 260z with round-top SUs from my 240z with L26, its not bad, it's a single click to get that engine running, even after sitting for a long time.
On the carb setup, I find the fuel smell to be a bit overwhelming, to the point where I don't want to drive the car as much because the passengers reek of fuel when they get out. I cant even run a shitty CAT on the exhaust because it would get destroyed by the carb. This is probably also due to leaks in the body gaskets...
I think it's really just the turbo that I want, I cant get smoked by these civics :(
if you already have a carbed zed then why not! the block is bulletproof I bet it takes the turbo like a champ.
I was gobsmacked when they announced for DOHC head, is there some context I am missing as to why this makes sense for them to make as a heritage part?
I absolutely love the heritage program. It's a love letter to its past and current enthusiasts and I hope it also makes business sense, so that it continues.
