*Sticky* Ultimate KA24DE

[keepingthe240]

The stock rocker arm ratio is 1.422:1 I'm guessing longer rocker arms( a higher ratio) bigger valves <--go with some lighter valves for that matter and u can use softer springs. I've always said redesign the crank..but i've been too lazy to track down the guy that could tell me how and lastly is cryogenics.. Aries...anything were missing?? Aries should be able to tell us if a roller rocker would work!!

Oh...longer connecting rods for a higher rpm.

OH God, your serious about the roller rockers? On a DOHC motor? seriously

I'm looking at trading in my DSM and buying a 89-94 240sx...

but I have to say this thread is really gay, not because of the fact that even if you're crazy enough to spend the money required to do all these mods you will still be slower than your average KA-T, but because just listing every single mod you could possible do to a car for no reason is gay.

^ first off, i have doubts that this thread likes other boy threads, also, why not list everything? it will make a decent reference list, maybe some helpful advice will sneak its way in. also, ppl are bored, why not make this not so lively forums more interesting??-Enzo

Here's another one: Intake manifold gasket...

Supposedly, they're supposed to block the heat from going from the head to the intake manifold, and thus keeping the air cooler for a more dense charge. I was thinking of making a teflon one, which is incredibly heat resistant, since my dad owns a company that makes teflon gaskets...

Maybe you're right Enzo, its just the way this thread came off to me when i read through. Only third time reading this forum, guess I'm still thinking "out of the box"

[EnzoRWD]

no worries,

btw- if you get one of those teflon gaskets made, be sure to tell us all about it...:P-Enzo

i read somewhere that one of the manufactures is using a plastic type i/m gasket. plastic conduts little heat supposedly. sounds pretty cool. wouldn't be that hard to make up if you could find the right material in the right thickness.

i would add titanium anything you could find. particularly in the valve train.

No point in bothering with roller rockers in the DE, they are already an 80% mechanical valvetrain.The E however is a different story; even then, custom ones would have to be made.

Yeah. Teflon is similar to plastic.. and it would be very easy to mass produce it too. Does anyone make it for the ka yet?

why not bore a KA engine?

MustangManV6, you can. The cylinder walls are not extra thick in the first place but most blocks do have some boring room (in a non-boost lower heat NA setup). I have and currently run a ka24e 240sx block bored to 91.1mm (.080" over) with high compression. This gives a 2502cc displacement with stock ka stroke. It has proven to be a bulletproof setup so far.

The mexico cast ka blocks that i have checked (ka24e truck), have slightly thicker cylinder walls. Im not sure if the mexico cast ka24de blocks are similar.
