jessejames Posted May 30, 2021 Share Posted May 30, 2021 (edited) Hello, so I'm starting a new project. I'm pulling the Sr20det out and swapping in a Honda K24A2 turbo engine into my 1973 240Z. This is a list of the basics: 2006-2008 Honda k24a2 2.4L vtec Cd009 Nissan 370z transmission Efr8474 twinscroll turbo Haltech elite 1500 Ecu. This is my first attempt to do a build log.

Exposed Posted May 30, 2021 Share Posted May 30, 2021 Excited to follow the build! Any pictures? Quote Link to comment Share on other sites More sharing options...
jessejames Posted June 11, 2021 Author Share Posted June 11, 2021 Nothing to exciting to report. I've attached a picture of the new turbo, intake manifold and brake kit. The picture with the sr20det is how it sits. That motor should be out by the end of the weekend. Quote Link to comment Share on other sites More sharing options...
jessejames Posted July 6, 2021 Author Share Posted July 6, 2021 Not a alot of progress. Dry sump kit is missing pulley. Hopefully will here back from the vendor soon. Some pictures of assembled motor to make motor mounts. Quote Link to comment Share on other sites More sharing options...
jessejames Posted July 7, 2021 Author Share Posted July 7, 2021 Trying to mount engine and transmission. Using the apex engineered for the transmission mount. The dry sump pump is making contact with the cross member. The transmission is alittle lower than I like. Quote Link to comment Share on other sites More sharing options...
jessejames Posted July 10, 2021 Author Share Posted July 10, 2021 Engine mounts made, just need to adjust one. Need a spacer for the oil pump. Transmission is now sitting in better spot. Quote Link to comment Share on other sites More sharing options...
jessejames Posted July 21, 2021 Author Share Posted July 21, 2021 Quick update: U joint had to be added to steering shift to fit around motor mount. Turbo manifold is done. Bolt for the crank pulley is too long to fit the ati dampner. Quote Link to comment Share on other sites More sharing options...
heyitsrama Posted July 22, 2021 Share Posted July 22, 2021 I wonder if the frame will flex on load and cause the steering intermediate shaft to bind…. Quote Link to comment Share on other sites More sharing options...
AydinZ71 Posted July 22, 2021 Share Posted July 22, 2021 Looking good! I think the K24 setups in a Z is a great option honestly. Great power with light weight. @heyitsrama this specific section of the subframe does not flex a whole bunch under torque. The nearby tie rod mounting box is the thickest steel on a Z. If it does bind, if blame steeper angle on the steering linkage. Ask me how I know so much about the subframe 🤣😂. I have rebuilt this whole section of the car in new steel. you do make a good point though, the whole subframe should be reinforced and/or a roll cage added for rigidity. Looks like this setup will produce at least 300ft-lbs which is where I feel the stock frame starts to flex too much. Quote Link to comment Share on other sites More sharing options...
jessejames Posted July 22, 2021 Author Share Posted July 22, 2021 I will look into reinforcing it further. I have some done. I've got a welded rollbar at the rear, and brace on the front struts. I'm just waiting on the fuel rail, clutch, spacer for dry sump, and few other things. In terms of power. Similar engine with same turbo was making 600whp. I'm planning on running less. 1 Quote Link to comment Share on other sites More sharing options...
heyitsrama Posted July 23, 2021 Share Posted July 23, 2021 I've been eyeballing k24's as a potential swap if my current motor goes out the door. Seems like a great platform. Why the dry sump? Just because you can? or does it help with clearance? Quote Link to comment Share on other sites More sharing options...
heyitsrama Posted October 13, 2021 Share Posted October 13, 2021 http://www.speedhunters.com/2021/10/k-powered-party-front-party-back/ Saw this project online then was thinking about this Z, any progress? @jessejames Quote Link to comment Share on other sites More sharing options...
jessejames Posted October 24, 2021 Author Share Posted October 24, 2021 South Bend clutch and new injectors have arrived. The shop is a little swamped with cars, but I should back in very soon. I was hoping to get it done before winter, but I think the new goal is to be road ready before spring. Why the dry sump? Just because you can? or does it help with clearance? I went with the dry sump as the k24 is a very tall engine, and I was concerned about the oil pan hanging out of the bottom of the car. I thought about trying to make a custom oil pan, but went alittle blingy. Hopefully I'll have more updates in the next month. Quote Link to comment Share on other sites More sharing options...
A to Z Posted December 1, 2021 Share Posted December 1, 2021 It owuld be really nice if you can pull the engine one more time and take the time to paint and detail the engine compartment and the engine and then re-install. Quote Link to comment Share on other sites More sharing options...
artzm Posted January 23, 2022 Share Posted January 23, 2022 Hi can you send some info on the way you’ll be doing the wire harness and engine management, I’m doing exactly the same set up k24a2 with CD009 thanks Quote Link to comment Share on other sites More sharing options...
jessejames Posted October 1, 2022 Author Share Posted October 1, 2022 Sorry for the delay, life gets in the way of project cars. I ordered a custom wiring harness from rywire. I didn't want to mess about wiring. Everything is beautifully labeled. I had to add a spacer to the intake manifold to make the dry sump tank fit. It's a 2.3 gallon tank. 1 Quote Link to comment Share on other sites More sharing options...

The front Brake caliper brackets included with the kit, would not fit. I had to have a machine shop alter the brackets. I plan on having completely new brackets made once i finish moving.

jessejames Posted March 27, 2023 Author Share Posted March 27, 2023 Sorry for the delay. Between moving across the country and trying to finish this project, its been tough. Theres been alot done on the car. There's been some problems that we are still trying to sort out. We used the Collins K24 to CD009 adapter plate and flywheel. The flywheel bolts they suggested were too short. We end up ordering new bolts from ARP. We installed the adapter plate and flywheel with a ZSpeed Heavy Duty V2 CSC HD Concentric Clutch Slave Cylinder and a Southbend Street Clutch. Unfortunately the fingers on the center of the clutch are touching the outer body of the slave cylinder. The stack height is too tall even with the clutch adjusted. We might try to shave down the black bracket to make some space. We used a Serial Nine shifter relocator kit and that has worked wonderfully, and placed the shifter in the OEM hole in the transmission tunnel. We had new piping made for the intercooler and turbo and it turned out beautifully. The height of the OEM valve cover is a bit high. I might switch to the Skunk2 version for some extra clearance. The Tractuff water plate block off works well, however their alternator relocation bracket does not. The alternator twists under tension with the belt. I've noticed since I purchased the kit, Tractuff has changed their design and has a stronger bracket but they will not offer an exchange or warranty. I'll try to get some pictures of what I mean. We started the car and found we had 65 psi of oil pressure at 2000RPM, to we are going to switch to a thinner oil. I'll update when I can.
