carbed ka?

[seth240sx]

has anyone carbed their ka and ran individual throttle bodies?i think that would be really damn cool.How hard would it be to do.I think it would make a lot of power.

[deviousKA]

The highest hp naturally aspirated ka runs sidedraft carbs, as do most that run over 200hp. BTW, the highest hp NA ka (that i know of) puts out 298hp and 260ftlb torque.

OMG lies evaryone knoews that u can't mak a gud n/a ka!!1111 you gots to be all jdm tyte with a mad turbo n ****.

HAH, Insanity is right, its all a big conspiracy, High HP ka's do not exist, well at least not without a bling plenum manifold thas all you need bro.

All i gotta say is, learn your internal combustion engine physics, the human mind is easily capable of such a simple feat.

Harmonics and rotating efficiency is where it lies, THINK, THINK, THINK!!, It is history now, surely you can learn what has been thought and proven before. No need to dwell in time. If you want results you need to act with what you know and/or want to learn, it is all there at your fingertips considering your level of interpretation (only thing seperating those who do, and those who dont).

Ok, Im done

Oh wait, no im not. Spy shots courtesy of Art Schmitt, Art Schmitt racing team. 298hp (8200rpm) ka24



Gotta love the oil tank

Ok now im done, people are scared

hey whered you get the pictures of my engine

[InsanityInc]

That engine has ITB's... intake manifold physics don't really come into play when you..don't have an intake manifold.

Also, how did he get a KA to rev to 8200 without the crankshaft snapping? Is it destroked or fully counterbalanced or what?

[250sx]

Anyone know where to get that kind of manifold for the twincam?

[deviousKA]

Custom only, either using stock manifold as a base, or fabricating from the ground up using new flange and runners. That is, of course, if you dont know anyone with a foundry that could cast you one Ill try get in touch with Art Schmitt or someone on his crew and ask, but all other carbbed de's i have seen have been all custom.

[AN89HATCH]

Where can you get the itb adapterplate for the sohc? or must this be custom also?

[250sx]

the sohc has a nismo manifold for throttlebodies or carbs. I would rather have one for the dohc but It has to be custom. I wish I could weld. Maybe I could make a steel one...but that would suck!

[ilsha]

i would make your own before buying a nismo one, the piece is so simple to make

[sleepyRPS13]

im skeerd

[Guam_Guy]

Dont be it's easy

The most time consuming part of this was welding the carb flanges onto the manifold.

[250sx]

nice work on the manifold...is that a 12v or twincam manifold? looks like a sohc but I havent looked at one in awhile.

[Guam_Guy]

Thanks, it's for a twin cam

[PandaS14]

Guam Guy:

how well did the carb flange ports match up to the intake mani ports? that looks like the stock intake mani, right? I'm assuming you cut the runners off right where the carb ports match up? Which carb flanges are they? thanks in advance!

[j-z]

post pics and results when youre done. looks clean

[Guam_Guy]

The ports matched up almost perfectly. I had the flanges made at a local machine shop my buddy owns and TIG welded them on. The stock manifold was cut six inches from the mounting flange. I used my carb spacer as a template. Here are some shots of the motor I am building right now. It is a Z24 block with a KA24DE head. It is in it's mock up stage right now.

[j-z]

this interests me alot. whered you get the carbs from? what did you go by on how to do this? what parts did you need? also, whats the diff between a z block and ka block? please give some more info. thanks

[PandaS14]

I'm also very interested to know which carbs you are running. Is the port spacing unique to that carb kit or is it somewhat standard. DCOE? please forgive me, I know hardly nothing about carbs. Also, why did you have to make a flange? wouldn't the carb manufacturer make one that you could just weld on? THANKS!

[Guam_Guy]

There is not really that much difference between the Z block and the KA24E block. The big change was made with the KA24DE motors, witrh the De blocks they added a crank giridle and oil squirters. The reason I am using the Z block is because I have about three sitting around here.

As for how I learned, I have been working on old school nissans for a while. From the A series motors to an RB I did for a buddy of mine. I have toyed around with my share of motors.

I was gonna use this KA24DE motor I have but I would have to spend more money trying to get it in. You see my truck is a Nissan 720 pre-hardbody. The KA24DE motor I have is from a 1991 240Sx my old car. The front sump design of the KA24DE motor interfears with the steering the the 720.

I have a guy in NY that supplies me with Mikuni PHH side draft carbs. They are getting harder and harder to find nowa days. If anyone in here needs any I can get you a set of 44mm about $750.00 new and about 600.00 used but rebuilt. The mounting flange is pretty much the same between the Mikuni PHH, Weber DCO/DCOE and Dellorto DHLA . Stay away from the Solex ADDHE, you will have a hell of a time trying to find the rebuild kits for those. Also be aware that if you buy Solex carbs from italy, you will be buying junk. Unless it says Mikuni/Solex don't even waste your money.
