2quick Posted February 4, 2020 Report Share Posted February 4, 2020 so I picked up a 71 521 last weekend for $500. I had a 71 in highschool and always regretted selling it but I saw this on facebook and had to get it. Didn't get really any info the kid I got it from got it the same way and didn't do anything to it. kid said the guy before him was putting a chevy 350 in it but I think a v8 would be a little much for one of these and I wanna keep it Nissan so Im gonna do a ka24de swap. it has a fairly good looking napz motor and trans just sitting in it but im gonna pull it and sell it so if anyone needs a napz motor and trans in nor cal i'll have one cheap! haha. the firewall and trans tunnel are cut up im guessing for the 350 so I gotta weld those back in no big, prolly gonna wait until I source a ka and get it mounted. I favorited the DIY ka in 521 post so i'll use that for most of my info seems like that guy has it down. Also I found a guy named beebani on ebay that sells brackets for disc brakes and coilovers for these 521's but I wanted to see what you guys thought? 2 Quote Link to comment

mrbigtanker Posted February 4, 2020 Report Share Posted February 4, 2020 KA swap would be so cool, I don’t think any are out there. You would be the first. 1 1 Quote Link to comment
datzenmike Posted February 4, 2020 Report Share Posted February 4, 2020 D21 HB KA24DE would be easiest. See ]2eDeYe for the engine/trans mounts. Make aluminum plate for Weber carb and L20B matchbox and you can forget the EFI swap electronics. I think the KA24E looks nicer. 2 Quote Link to comment

4perrev Posted February 8, 2020 Report Share Posted February 8, 2020 Sweet project. Good luck with the front window as I had to order one from Pilkington which comes out of the UK. $620 for that baby. Quote Link to comment
2quick Posted February 8, 2020 Author Report Share Posted February 8, 2020 I was actually lucky the guy had the front windshield. I just gotta get new seals and put it in 1 Quote Link to comment
