Hmmm... I'll have to look for that L20B reference I'd seen earlier. It made it seem a bolt-in. Of course, I'm unwilling to modify the frame, and if the U20 is as rare as it sounds, I'll either need to treat it more gently (hard to do -- it's so fun getting wild on the track with it!) or take the performance hit, if necessary, of an engine it wouldn't be devestating to destroy. I have a question that likely isn't directly relevant to this thread, but as the operator of a couple of message boards myself, I don't like creating new threads for too granular of subjects so I'll just ask here. http://cars.talkzilla.com/boards/read_msg.aspx?message_id=23115 Mine is certainly an omelet since it's a 1600 with all the appropriate pieces from a 2000. But note the frame rail and the font. Can anyone confirm whether that's the font Datsun used for stamping VINs on frames? And whether they dented the frame rail like this in the stamping process? In a way, too bad it's an omelet as it appears to be way up the list of last ones built (within last 2000 of them, so maybe within last few hundred still operational?), but if it wasn't a mutt, I couldn't stand to have the fun with it I do. And if you see all the verbiage I've written about the car on my site, you'll see how much I adore it especially when seriously driving the wheels off of it.

Sweet car, Jason. Here's mine. Yours is the first I've seen the same color as mine. I need to get a set of stock wheels though. When I was prepping it for a track day, I put smaller tires on it, probably a little smaller than yours, to lower the overall effective gearing and gain some contact patch, and noticed the wire-basket wheels on it are HEAVY! Do you know if the U-20 is at all rare these days? I believe it was also their truck engine, so perhaps not very rare. Still, I've considered taking out the U-20 and storing it and, what the heck, while I'm at it and do occasionally use it at track days, see what else I can stuff under the bonnet that's less valuable but more powerful. I was initially thinking about building an L20B for it, since I have a lot of experience with that one, but in snooping around the net for a posi diff for it (or, dare I hope, a posi IRS rear that fits right under it?) I ran across a lot of references to later and larger motors being bolt-in replacements for the U20. Thoughts?
