JayD Posted December 11, 2010 Share Posted December 11, 2010 I was wondering if there were any heads off of any other engines that would mate up to the Z24 block, and if so, any that are preferably FI? I may have asked before... not sure if I did though... I don't nescessarily want to change out engines, because I want to see what kind of potential the Z24 bottom end has. Another reason I want Fuel injection, is so that I can boost it, using MS standalone. I could fab a mani for whatever trim turbo I wanted, but I need some helpful words of encouragement and a point in the proper direction before I go tearing stuff up and trying to rewire everything. I'll do a google search, and see if I can find something in the meantime, but I figured I'd ask the gurus first. Cheers! Link to comment Share on other sites More sharing options...
JayD Posted December 11, 2010 Author Share Posted December 11, 2010 (edited) I see the KA... anyone elaborate on it? I'll keep digging. I see the one I want... KA24DE (T in the future...) Edited December 11, 2010 by JayD Link to comment Share on other sites More sharing options...
Kingman Posted December 11, 2010 Share Posted December 11, 2010 Well you'd be pretty hard pressed to blow the bottom end of the Z24 out. The Z24 and KA are basically an L-series with a different head, and L-series bottom ends don't blow up. I have one in my '76 pickup that's got 400K miles on it and has had a very hard life towing stuff that was intended for a 3/4 ton pickup. You could probably build a KA24DE to make decent power if boosted but they aren't that torquey of a motor which is what an SUV needs. I'm fairly sure the bell housing is the same between the KA and Z24, and the KA head *I think* bolts on to the Z24 block. Link to comment Share on other sites More sharing options...
nunya Posted December 11, 2010 Share Posted December 11, 2010 and the KA head *I think* bolts on to the Z24 block. if someone got a z head layin around I can measure/compare measurements to a ka head for them (have one of them) Link to comment Share on other sites More sharing options...
JayD Posted December 12, 2010 Author Share Posted December 12, 2010 I would love to find out, See fabricating things isn't gonna be tough for me... I'm a mad scientist. Bwhahahaha, Whats the Compression ratio on the stock TBI Z24? If possible, and I know it'll need it anyways, is to deck the new head, and see where I'm at from there and see what I'm looking at as far as boost. I wonder if... I'd have to get the whole thing rewired, but how much room is under the hood with JUST the plenum? I wouldn't mind tinkering with a 3800 supercharger idea... I know someone that fabbed one for a mazda protege, so if that's possible, then there is no reason, that with EFI, that I can't do a similar setup. It would require me to do a LOT of research on air flow in the KA/Z head, possibly fab up some custom intake runners with butterfly valves that open up more at about 4k.... Damn at the ideas!!!!! If it were possible for me to make a supercharger plenum with all the hardware.... Wait... I'd have to figure out the I/C setup as if it gets mud between the fins, it'll decrease performance. I'll do a bit of research and see if I can make sufficient boost without needing an I/C... Probably not enough to make a noticeable difference. I guess I'll have to do my homework, take some measurements... and get to mocking a setup up so that it will be road ready by at LEAST spring 2012.

JayD Posted December 12, 2010 Author Share Posted December 12, 2010 Ok, so rated stock Hp/Tq for the Z24 TBI is 103hp/134Tq... The KA24DE is rated at 155hp/160tq. Still researching if anyone makes a S/C kit for the KA24DE.... Link to comment Share on other sites More sharing options...
