KA24 NA Stuff, u can ignore me Options

[sideways_s12]

The more and more I read this thread the more and more I want to ditch my ca18 build and go for a ka build instead...damn I'm soo torn

[200sxkitcar]

The KA can handle boost nicely, as long as you aren't looking for anything crazy, then internals need to be upgraded. But out of the box, .6L more displacement is nice. Not a high-revver, but with that torque....

i realize that OEM is the best fit on a rebuild kit

but, the aftermarket of the KA is prob vey high because of the 240.
are there any performance rebuild kits?

or would OEM be good enough?




fits a VG30E, thats cool

There are performance rebuild kits, can get pricey, but oem ones are good enough.... depending on what you want to do. The OEM stuff is good enough up to a certain point, and then you'll need to upgrade. You first have to decide what power level you need, and build accordingly.

The Cobra MAF can be adapted to any engine Jim Wolf works with, as they just reflash the ECU accordingly.

this thread is full of win! thanks sterling for gathering it all in one thread. now we need to start a ka-t part thread.

well im talking about just drifting, etc.

im prob gonna start with exaust intake and coil on my KA, will probally be basically it for awhile

but i want to be able to run hard, without failure, i dont need more then 200 HP in my range of fun.

i wanna stay around exactly 200


would OEM gaskets hold that?
or should i save more pennies?

Standard gasket kit+ metal head gasket (like Cometic), yes. Head studs probably good too.

For 200hp, you'll want a turbo setup, a simple one will do. 200hp turbo is very obtainable, stock pistons fine. 200hp on N/A? possible,.... but very expensive, and not very streetable. 200hp is a nice, obtainable, sane, non-parts-breaking, non-wallet-breaking, streetable goal. A basic turbo system will serve you well in this regard

Basic KA turbo system can be done for cheap if you hunt around, look for deals, listen to people, etc.

If you've got any questions regarding that, please start another thread. I've got no problem keeping up with a KA turbo thread if you want to have one

But for now, the KA's stock output of 160hp (maybe 140ish to the wheels) is good fun, and getting the engine in there and running will be enough of a challenge for you at this point (you're still learning) then you get to add boost and learn about that

agreed.
can you explain the standard/metal?

i realize i need nissan OEM gasket kit for a KA24DE

does the year matter for gasket kits?
and what else would i need for a rebuild?

[200sxkitcar]

A standard gasket is kindof this crush type material, softish, its metal tho. The MLS or mult-layered steel gaskets is what I was talking about, they are several thin layers of steel in an arrangement and locked together so that when everything is assembled its a stronger gasket. Its more rigid, if you want to think of it that way.

I'm still deciding on MLS or copper. MLS is really sufficient, but I like the idea of being able to reuse it in a teardown.

Go with whatever year the engine came out of. I haven't looked at my block, but on most engines there is a serial number, which you could go to Nissan with and have them look it up if you didn't know where the motor came from. Again, I don't know if this is true with Nissan.

A full rebuild kit is going to have the entire gasket kit, new piston rings, new rod and main bearings.

On top of this, you want a new water pump, thermostat (get the Nissan one), spark plugs, plug wires, cap and rotor, 5qts oil, new trans fluid, jug of new coolant.

New clutch/resurfaced flywheel.

Lots of chemicals including cleaners/degreasers, engine assembly lube, loctite (probably only need blue), pipe thread sealer (also called pipe joint compound, don't get teflon tape), other stuff I'm forgetting.

Clean surface large enough to work on.

A variety of engine rebuilding specialty tools, such as: Ring compressor, Plastigage, Micrometers, and other stuff I'm again forgetting. lol

Like I said, maybe not in this thread, but budget at least $500.

Again, not including any hotrod parts in there, all stock/necessary parts.

[frosti108]

that gauge and switch thing where the radio used to be is sweet. for my ka-t i just rock a boost gauge and wideband reader in the spot for the center vents along with a few swithes in the plastic thing around the shifter

[200sxkitcar]

Yeah, its pretty neat. Its on an S13, but its so pimp, I just had to share.

Oh and thanks Joe, its not done yet, but I definitely feel a KA-T parts thread being started, eventually.

Actually, a good deal of this info can go either way, really.

A more condensed/organized version could come a bit down the road, and be stickied.

I would have thought something like this in an organized form would have been done already on one of the Nissan/240sx forums, but I have yet to find one that is decent/comprehensive...

unless someone knows of one

a 500 dollar budget on rebuilding a 500 dollar engine is perfect
thanks for this,
this thread is BOOKMARKED,
and it means alot to me

[Arro]

I'm not trying to put down the club here, but the best KA-T info is ka-t.org.

Can it be better organized? I suppose so. And some of their info is a bit dated now too.

Since Sterling is manning the KA NA thread, I'll probably work on the KA-T thread myself. I need to since, well, he plans to stay NA and I plan to go turbo.

So it just makes sense.

Like Sterling said, much of the info in this thread can lean either way. But to keep things consistent I'll duplicate the info where applicable.

Sterling I still think you should play with ITB's and standalone at some point

[200sxkitcar]

Oh fuck, you bet. I've already been searching for ITBs, and have some leads.

Thats a ways down the road.

KA turbo info, definitely KA-t. We may not bother starting a thread, but its good for asking questions I suppose, or providing links. I'll not mess with that, leave it for one of you fellas.

what about carb setups? where are they to be found? iv'e sean them on mini trucks and 510's with the ka's, single slam or the duals, but i have yet to find a dual carb setup for my ka24de. who makes one? how much? as this is something i'm somewhat intrested in

[200sxkitcar]

Personally, to me... Carbs=evil. I don't know how to tune them, the can't compensate for atmospheric pressure changes (applicable to me, I'll be living near the mountains and you'd better believe I'll be up there), don't have a computer to tell me whats wrong, don't get as good gas mileage, etc.

Not that its not doable, its just totally not me.

If you were interested in that route (which would be hella cool and easy if you knew how to do it) I would go after the Datsun guys, who have done carbs on KA, and see what they say.

In other words, I would look to them, and copy their setups.

For midwest/east coasters, I picked up my Mishimoto rad SHIPPED for $225, that comes directly from the manufacturer, which is out of Georgia apparently. Just make sure you clarify whether you are getting a KA one or an SR one, because they had me set up for a SR one when I went to check the part # so just varify that its a model # MMRAD-240-89KA and you should be fine.

There are plenty on the east coast, but I would shop around for best price... this supplier was in the midwest section on the distributor page.

ive seen carb conversions on ka24e's. jwt is a rip, get something that you can tune the maps yourself. i was looking at daughterboard setups and bikirom looks pretty good, its just that it would be hard to find a local tuner. i know a few people myself but for the average guy its hard

[200sxkitcar]

Yeah, JWT is expensive, but their product is good. I'll look into those other two you mentioned, as I'll be living in socal shortly, and finding a tuner there shouldn't be too difficult.

[frosti108]

if your looking for a tuned ecu you need to get in touch with jason from e-mance. he hooks it up for CHEAP. socketed and tuned my KA ecu for 85 even!!! nothing jwt can do that e-mance cant
