Like Jordan said, it's harder to fit a front bar with an SR swap, but there are a few OTS solutions now such as MadDat and Futofab. I drove my NA SR car w/o a front bar at Thunderhill and it was a real handful. Entertaining, but felt like it was only a matter of time before I'd loop it, but never did. Fortunately, Michael was able to deliver a MadDat bar to me the next day at Shasta. I fit it in the parking lot, and was off to the races after that. That was 200hp. Personally, I would consider an SR20DET 510 with 250+ hp a road hazard w/o a front bar. Unfortunately there's too many running around out there like that. They handle great on the straights, though. I'm pretty sure those who prefer to tune with springs run at least front bar.

“The whole wrong motor discussion was exactly about this so long ago. If the swap doesn't drive better, it's wrong.”
Accurate! Also “drive better” is in the seat of the driver, not necessarily a widespread view. I have probably the most wrong motor 510 on this list, and while *I* love the car I am not under the delusion that most 510 guys would enjoy driving it, because it really doesn’t drive anything like a tossable, lightweight L-powered 510.
Putting a lot of time and money into your own vision of a 510 doesn’t guarantee you’ll get even 50% of that back when it’s time to sell. But also to Brock’s point I have no idea how people put so much tine/effort into a car only to sell it later, unless it’s one of those ‘enjoy the build” types who want the challenge of a build and don’t really want to own whatever the final product is.

“it may appear like an '80s period street 510 from 20 yards away”
Bingo. My latest changes had 2 primary goals
1. To a non-Datsun person, look like a fairly typical 510 (now featuring cartoon wheels). I think I’ve counted 12 things that a 510 person would notice that a non-car person wouldn’t blink at as different from stock (Schiwsow didn’t even notice the fender flares until I pointed them out, for example)
2. Have 100% of the daily driver features off a bone-stock 510. Wipers, heater, spare, rear seats, etc. because it will be driven in all seasons.
The 510 is an easy platform to work with, easier in some aspects that Carson’s NA Miata. If I had the space I’d have another 510 and keep it a 4-cylinder.
You have a build blog someplace on that build, Tom?
