Thank you both! I didn't even know yahoo auctions were a thing.

I speak and read some Japanese. Any suggestions on where the Nissan people in Japan hang out online? It sure isn't craigslist. I know I'm unlikely to find a fuel injected manifold, but hey it's worth trying.

Oh, this is a side note: I'd been looking for a set of motorcycle throttle bodies for a while, to stick on my A series, but there's not a lot in the 1500 CC range. Then a friend pointed out that 1500CC's at 5000 RPM is the same as 750CC's at 10,000 RPM. Duh. So, my next major project will probably be putting a hayabusa or similar set of throttle bodies on the A.

The vortec 2200 sure does look attractive, now that I check it out. I'll look around at the junkyard next time I'm there.
(It's a huge drag fitting any sort of large transmission in this car. There's no transmission tunnel, which is nice, but the frame is really narrow, getting down to only maybe 20cm between the frame rails just in front of the differential. The 63 series transmission fits beautifully, though.)

I feel like I'm keeping it Triumph with the Datsun engine, since Datsun licenced the A-series from Triumph originally, apparently. So I figure I'm using the engine Triumph engineers would have designed if they had the time and money.
I'm still looking into the L-series, trying to find one locally that I can do some measurements on, but that Chevy inline 4 sounds cool. A crossflow would really help me with size constraints.

I appreciate the advice. Putting a turbo on is a huge challenge because of space. (The engine compartment is really tiny.) If I put the alternator over on the intake/exhaust side and use an EDIS for ignition, I can just fit a small supercharger on the non-intake side.
Presumably like the Z head, the NA head bolts onto (with some modifications like a swapped cam belt cover plate) the L-series block?
3.5mm deck height isn't the problem: it's the head and valve cover.
From pictures, it looks like I could possibly use a jackshaft with the larger pulley that drives the cam on it, and then a small pulley on the end of the cam, so that would allow a custom valve cover, but ugh that's a lot of work and reduced reliability.

I have an A14 in a Triumph Spitfire. It's been a great engine. I'd like a bit more power, for around-town driving, and after reading a bunch about heavily modifying the a14 or putting a supercharger on it (which I still might do) I started reading about the L18. It appears the block is only 4mm or so taller than the tall-deck A. A Spitfire is really, really small. There is about, maybe, 10mm of space between the hood and the oil fill cap on the valve cover, and I cut out and welded up an absolutely minimalist oil pan to get more clearance on the bottom.
So: what's the height of an L16/18, from the bottom of the oil pan to the top of the valve cover? Anyone know? I'm thinking from the higher part of the oil pan, not the sump, because if I were going to do this, the oil pan has to sit over part of the frame but I can make sure it's the highest point on the oil pan.
Any advice or numbers appreciated. I have another A14 sitting in the basement so I have measurements for it.
Thanks!

Keep looking on craigslist or in local scrapyards for B210's. It took me two years, but I found a guy selling a trashed B210 for $1800. I drove it home and pulled out the engine and transmission, and sold the rest to a scrapyard for $200. That's not cheap, but for my situation it worked really well. (I needed the whole emissions and carburetion system intact.)
My plan had been to swap my four-speed into the B210 but it was in such bad shape I didn't feel right selling it as a driving car.

Okay, that's really cool too. What ITB is that? It looks like all it needed was holes redrilled to make it fit onto a stock intake manifold? That would make my life a lot easier.

So how do people manage fuel flow through a single injector? Make it four times as large, or have it operate at four times the duty cycle?

That is sweet. What ITB's are those?
I'm partly interested in a plenum because I may boost the engine at some point, at which point I know volume doesn't matter so much because the pressure makes up for it. But that's a huge project so getting it driving with FI first seems like a good idea.
