Trophy24 Posted October 31, 2021 Report Share Posted October 31, 2021 What is the future engine swap of choice for our Datsun’s? Hmm let’s contemplate that for a minute or more. The prices for some of the go to engines have gone up significantly recently. Supply is dwindling for the imported SR that is so popular. What will we do in a year? How about 5? What if you are racing in an endurance format that will push your engine enough to have to plan for it’s demise at some point? We will be exploring an option here that others have found great success with. The Honda K24. Some of you will find that a terrible idea for (insert reason)! That’s ok for you and your car. This thread will follow the journey that will hopefully end with a successful install into one or more of our local cars here. Follow along with us as we solve the problems associated with integration into the 510 chassis! 1 Quote Link to comment
Trophy24 Posted October 31, 2021 Author Report Share Posted October 31, 2021 The K24 is available at your local junkyard for a reasonable amount of money. Show up on a 25% off day and it gets even better. When you cut the front of the car off the engine comes out much easier LOL Look at Jeff go with the sawzall! Quote Link to comment
Trophy24 Posted October 31, 2021 Author Report Share Posted October 31, 2021 Our buddy Dave helped us get it out in less than 2 hours. This is an Accord engine set up for fuel economy. We chose this one because it was cheap. Mocking up and fabricating will come with risk of metal contamination. Better to start with this one and not worry about it. Quote Link to comment

Trophy24 Posted October 31, 2021 Author Report Share Posted October 31, 2021 (edited) Removed all the things not needed for mock up and fabrication. Purple power should clean this up nicely Edited October 31, 2021 by Trophy24 Added text Quote Link to comment
Trophy24 Posted October 31, 2021 Author Report Share Posted October 31, 2021 After pressure washing. Can’t sneak it into work for the 3D scan if it will leave grease and oil everywhere Quote Link to comment
datzenmike Posted October 31, 2021 Report Share Posted October 31, 2021 Converting to RWD? What transmission will you use??? Quote Link to comment
Trophy24 Posted October 31, 2021 Author Report Share Posted October 31, 2021 Yes converting to RWD. Our goal is to use the 71C 5 speed. We could use the adapters available right now to install a different transmission, but the cost factor is driving this in another direction. Quote Link to comment
Stoffregen Motorsports Posted October 31, 2021 Report Share Posted October 31, 2021 Is there an adapter available, or do you plan on machining one yourself? Quote Link to comment
Trophy24 Posted October 31, 2021 Author Report Share Posted October 31, 2021 We haven’t found an adapter for the 71C. Other transmission adaptations are available if you can spend enough. Since we Have the transmissions and capability of creating an adapter, this is our current route to follow 1 Quote Link to comment
Trophy24 Posted October 31, 2021 Author Report Share Posted October 31, 2021 Scanned! 1 Quote Link to comment
carterb Posted November 1, 2021 Report Share Posted November 1, 2021 Looking forward to getting the scan into Solidworks! 1 Quote Link to comment
Stoffregen Motorsports Posted November 1, 2021 Report Share Posted November 1, 2021 Are you planning on making a simple plate? Or a bellhousing? Quote Link to comment
Stoffregen Motorsports Posted November 1, 2021 Report Share Posted November 1, 2021 (edited) I found this A series diagram while poking around the web the other day. Makes me wonder if someone has an L/Z/KA motor diagram - http://datsun1200.com/modules/mediawiki/index.php?title=Bellhousing Edited November 1, 2021 by Stoffregen Motorsports Quote Link to comment
Stoffregen Motorsports Posted November 1, 2021 Report Share Posted November 1, 2021 FYI - the 1983 280ZX Turbo had a T5 transmission with completely removable bellhousing (as opposed to the removable but integrated bellhousing on the 71 series trans). Might be worth looking at as a starting point. Quote Link to comment

carterb Posted November 3, 2021 Report Share Posted November 3, 2021 Collins has Honda K-series to KA24DE, isn't that the FS5W71C? https://collinsadapters.com/adapter-plates/honda-k-series-to-toyota-gt86-scion-frs-subaru-brz-ka24de-adapter-plate.html 1 Quote Link to comment
Trophy24 Posted November 3, 2021 Author Report Share Posted November 3, 2021 That looks interesting. We will have to consider this Quote Link to comment
JacobBieg Posted November 3, 2021 Report Share Posted November 3, 2021 So I have recently purchased a 1979 datsun 210 and after changing the sparks I've noticed oil in the spark well, which normally is a pretty easy job, however I cant find spark well gaskets for my model anywhere. Any ideas? Quote Link to comment
Stoffregen Motorsports Posted November 5, 2021 Report Share Posted November 5, 2021 This is what you call a thread jack. Try posting a new thread in the 210 section.

Trophy24 Posted November 7, 2021 Author Report Share Posted November 7, 2021 The adapter to the transmission is available for several different options. The 71C that we have most abundantly is for the 240SX with a KA24DE. Think we will go with that one. Grassroots racing sometimes means you build it yourself to save some money. Time to scan the front half of the transmission case 1 Quote Link to comment
Trophy24 Posted November 7, 2021 Author Report Share Posted November 7, 2021 Time to confirm angles for installation. Found a nice reference on the bottom of the front case. 2 Quote Link to comment
Trophy24 Posted November 7, 2021 Author Report Share Posted November 7, 2021 Work in progress. Should be done soon with the expert help of Jeff and Carter. 2 Quote Link to comment
