5&dime720 Posted May 26, 2008 Report Share Posted May 26, 2008 Hi all! I have a 240 SX KA24E head that I would like to trade for a truck KA24E Cylinder head. If you have what I need please let me know. The head will com complete with rocker arm assy, cam, valves, basically fully assembled. The reason I am looking to trade is because my side draft manifold is for the truck cylinder heads! Thank you! Link to comment
yello620 Posted May 26, 2008 Report Share Posted May 26, 2008 I thought that they were both the same head. What is different about them? Arent people using the 240 intake system on the truck heads? Jason Link to comment
5&dime720 Posted May 26, 2008 Author Report Share Posted May 26, 2008 Visually they are different. Stock intakes may swap but I got a old school BC Gerolamy intake for Mikunis that is only compatible with the truck engine cylinder head. Link to comment
kiznook Posted May 26, 2008 Report Share Posted May 26, 2008 you shouldn't have any problems making the manifold fit on the 240 head. Sounds like maybe your manifold is for a Z24 head? Link to comment
datzenmike Posted May 26, 2008 Report Share Posted May 26, 2008 I think they are the same. The FWD are different for sure. Link to comment
5&dime720 Posted May 26, 2008 Author Report Share Posted May 26, 2008 No, my manifold is for the KA. The intake ports between the two heads that I have are very different. Maybe difference in years. the blocks are different too. Basket / dampener crank shaft journal assy and the truck has independent journals. So any one want to trade me? Link to comment
datzenmike Posted May 26, 2008 Report Share Posted May 26, 2008 Pictures???????? Is it a DE rather than an E head??? Link to comment
kiznook Posted May 26, 2008 Report Share Posted May 26, 2008 The blocks ARE different. Do you have any pictures of the Head/Manifold? Ony persistent to help because it's always better if you can make due with what you have. And it might be somewhat difficult finding someone with a truck head. The only person I can think of with a truck KA is icehouse, and I don't see him takingit apart any time soon. If you do find a head that works, save the 240 cam, unless you have something else in mind. Link to comment
5&dime720 Posted May 26, 2008 Author Report Share Posted May 26, 2008 It's an E head. Not DE for Dual OHC I have had a running truck motor with my set up before.. Blew that engine up. It was built by Rebello Racing. I have a 240 SX head. I am assembling one engine right now with the truck head. I got another to build missing the head that I want and need. Can't take any pictures because of the compatibility of my Camera's software/ card with windows vista. Thanks for your replies all. Link to comment
5&dime720 Posted May 27, 2008 Author Report Share Posted May 27, 2008 Ok, I got it now. The top of the intake where the fuel injectors protrude, they are different between the two heads. The 240 SX head has a wider indentation than the truck head. The oval it's itself is the same. Now the 240 SX cam, is it different ? Link to comment
datzenmike Posted May 27, 2008 Report Share Posted May 27, 2008 Just get one of these and make them the same. I carved these injector notches in my Z24 head in about 15 seconds each. Easy Ratsun fix. :D:D Link to comment
kiznook Posted May 27, 2008 Report Share Posted May 27, 2008 Yeah the 240s have a slightly bigger cam. 89-90 240sx STOCK cam intake: 240 degrees duration, .409 in valve lift exhaust: 248 degrees duration, .409 in valve lift 90-97 Hardbody STOCK cam intake: 232 degrees duration, .382 in valve lift exhaust: 232 degrees duration, .382 in valve lift source: http://nissancustoms.com/showthread.php?t=4510 Since you're using carburetors, the best thing to do would be to fill the injector "notches" anyway since they wont be needed and will only impede flow.
