datsun 160J SSS Posted September 29, 2014 Report Share Posted September 29, 2014 Hi. I have looked all over the internet for what has been used to convert the KA24DE head to Datsun L20B block .I know it's been done but when it comes down to the detail it's never divulge what chain and gears are used .please can someone let in on the black magic .Anyone make the crank gear that fits the Datsun crank ??? Thanks Guy's Quote Link to comment
flatcat19 Posted September 29, 2014 Report Share Posted September 29, 2014 Im not sure the DOHC head will work. Single on a Z block...Sure. Believable. Why wouldn't you just the full KA? I think also knowing which way you go will change how successful this will be. Truck or car? Ignition system using? Crank angle sensor? Carbed? FI? OE or MegaSquirt? Lots of homework to do when doing anything custom with the DE. Quote Link to comment
datsun 160J SSS Posted September 29, 2014 Author Report Share Posted September 29, 2014 no it's been done . Datsun block lighter . L motor will rev. and you don't have to change everything but the color of the car for fitment . anyone know what timing kit will fit ? Thanks Quote Link to comment
flatcat19 Posted September 29, 2014 Report Share Posted September 29, 2014 What's the gain of doing this versus just doing the KA swap? Quote Link to comment
datzenmike Posted September 29, 2014 Report Share Posted September 29, 2014 I don't think there is a timing chain 'kit' for this as it's a jig saw of unrelated parts. You will have to maybe get a longer Z24 chain and shorten it to fit the KA24E. The DE was done in Oz I think, probably using the single link chain. The KA-E could probably use the dual link chain and L or Z cam sprockets. This is very interesting. Gain? Well on a 2 liter L20B it would be the ultimate breathing head on the cheap. Also on the LZ hybrid engines. Lighter blocks and crank and the L20B can rev. I suppose if you can figure this out on an L20B it would fit the smaller L16/18 as well. True the KA is already there and has lots of support but perhaps in a racing event that limits engine size? Quote Link to comment
flatcat19 Posted September 29, 2014 Report Share Posted September 29, 2014 Seems like so much work for negligible benefit. If, IF, this were to be the magic combination of parts it would be more documented and heavily copied. Quote Link to comment
datsun 160J SSS Posted September 29, 2014 Author Report Share Posted September 29, 2014 completed a ka24d setup that was bolt on hardest part was getting the LZ18 timing cover motor ran good . what am looking to do is a ka24de Quote Link to comment
flatcat19 Posted September 29, 2014 Report Share Posted September 29, 2014 Provide a link. If you keep saying its been done then there would be an answer to your question. Again, is the effort worth the reward? 1 Quote Link to comment
EastBay521 Posted September 29, 2014 Report Share Posted September 29, 2014 Provide a link no it's been done yes i too would like to see something supporting this Quote Link to comment
Draynor Posted September 29, 2014 Report Share Posted September 29, 2014 Its been done. But the cost is not worth it. http://m.youtube.com/watch?v=LLOEO3xkN4c 1 Quote Link to comment
datsun 160J SSS Posted September 29, 2014 Author Report Share Posted September 29, 2014 it's been done and am going to do it Quote Link to comment
datzenmike Posted September 29, 2014 Report Share Posted September 29, 2014 Wanting to put a KA head on is no different than wanting to put an L head on a Z22 or Z24. Is that worth it? Surely the KA head (DE or even the E) has superior breathing. It's cross flow design and multi valve and ideal for a turbo. I like the idea and win or loose would like to see the results.

Stoffregen Motorsports Posted September 29, 2014 Report Share Posted September 29, 2014 Found this: http://lescollinsracing.com/ It looks like they are using a single row chain. http://lescollinsracing.com/engine/projects-engine/l-series-4v Quote Link to comment

datzenmike Posted September 29, 2014 Report Share Posted September 29, 2014 300 horse L18? Not bad. But needs custom pistons and injection. Begs the question what would an L20B do? In theory 333 hp. Damn now what would it do with boost? Quote Link to comment
datsun 160J SSS Posted September 29, 2014 Author Report Share Posted September 29, 2014 That's what am talking about 300+ with boost . keep in mind am looking to build a motor with off the shelf parts maybe not 300 hp but I would like to find what will fit does not need to be a big valve head or one off crank Quote Link to comment
datzenmike Posted September 30, 2014 Report Share Posted September 30, 2014 The general rule is, the more air you can move through an engine the more power you make. The easiest way to increase the air flow (other than displacement) is to simply rev it higher. If you have unlimited air flow doubling the RPMs will double the H. P.. The problem then becomes the bottom end and how to keep the engine alive above 6 and 7K. Quote Link to comment

bananahamuck Posted September 30, 2014 Report Share Posted September 30, 2014 The machine shop that built that probably weighs the $100. dollar bills it would cost to recreate that thing,, as counting them would take to long.. Please,, this is like saying i wanna top fuel dragster motor for my 55 ford pickup,,, do you know who sells the oil pans... Oh and i've got a cost limit of $173.64 :rofl: . Pistons that were made just for that engine Custom billet crankshaft made just for that engine 1 Quote Link to comment
thisismatt Posted September 30, 2014 Report Share Posted September 30, 2014 Yeah, and what gas is any of this running. You can get 300/300 na out of the ka24e...not on pump gas, though. Quote Link to comment

The only thing anyone will see will be that fat KA head. All romance aside the L is stout, but it's not the best platform to make a budget high horsepower motor with. If you are the only one who will know what's under the head... what's the point? Quote Link to comment
datzenmike Posted September 30, 2014 Report Share Posted September 30, 2014 Working backwards... if the KA24E makes about 150 then a 2 liter which is 20% smaller displacement should make 30 HP less Quote Link to comment
paradime Posted September 30, 2014 Report Share Posted September 30, 2014 At 120 hp you might as well boar and stroke a Ford Cortina TL20 to 2.2L. It would be easier and cheaper than mating a KA head to an L20. Quote Link to comment
