Can it really be that much faster?
Um, no. Go ahead dump your oil and coolant, go drive your car, and report back how "fine" it did.
(No, please don't actually do this. Although here's a guy who did, for the clicks. The Honda did impressively well, but it wasn't "fine". https://www.youtube.com/watch?v=zyejT4VPzlE)
Oil not so much.
Any word on how much the Nismo head will be, the OS Giken one is absolutely eye-watering.
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 :(
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.

I’ll probably be doing my own windshield on my Tesla to avoid this. Safelight has decent prices but whacks you with a huge fee for pressing “calibrate” in the service menu, which is user accessible.
