A KA24DE-T'ers california dream manifold

Post by motoman399 »

hey so recently i got a pm from a guy asking me to do a custom manifold for him. im always up for some fab work so i agreed to the challenge. what he wanted done was take a stock sr20det manifold and cut the head flanges off, then weld on KADE manifold flanges.

so he ended up cutting the stock flanges from the KA and sent me the complete SR manifold and the KA flanges. then when i got it i cut the SR flanges. i beveled the edges of the manifold and the flanges then i bolted the flanges on to a spare KA head. got to welding.

here are the results of matty's sr24det (as he calls it lol)

here you can see where i cut the flanges and the bevel i put on the 3 and 4 runners
Image

we used s13 KA flanges and they needed some work to be used
Image

the result
Image

how flat the welds are

i would like to see a california highway patrol catch on to that car being modified! NOT GOING TO HAPPEN!!!

lol T2 VS. T4
Image
there is another guy that got a hold of me after i made this manifold and wants me to do another, and possibly one for a KA24E with a CA18DET manifold. should be fun



Thanks for choosing BADASS INC.

I approve of this post.

Does this wind up with a similar scenario to the ebay t25 manifolds where you have to lengthen the DP to clear the bottom of the car?

Are you running the VC vent to the airbox or the turbo intake elbow?

Yes, you still would have to lengthen the elbow or the downpipe. The KA sits almost 2 inches higher at the exhaust ports than an SR does.

Hope that helps.

did the same thing... 8)

sr20 mani modded to be used on a ka

using a ca18 turbo, with stock exhaust elbow

and

stock sr20 downpipe wich bolts up to my cat, and then to my catback exhaust.

all perfect fit :D

now if i could get that dam heatshield....:lol:

all this on a 95 s14 :wink:

looks good man. did you port match the inside? the one that i did, the ports were really bad and i had to add weld in there and then grind it smooth.

how long have you been running it, and do you live in cali?

yeah, i live in cali.

been running it for a month now.

and yeah, the ka flanges are bigger than the sr20 inlets, so i grinded the inlets first, then threw some artistic welds lol, and grinded them down.



on a side note...

how much for the zenki hud system?

it look nice on my rhd s14 :wink:

We need to be friends!! lol where do you live in cali?

im asking around 400 for it. i have the cluster, the module on the back of the cluster, the hud unit, and the bezel for it. i might have the right pig tails for the module too. i just havent tried them yet. i trade for rhd parts too. pm me

Thats a great way to get into a turbo'd KA for dirt cheap. If I could go back in time and do it all over again, I DEF would have done a simple setup like this at first, then progessed into something bigger and badder. Nice work here man....I'll keep this in mind if someday I want to build a daily booster.

ya this is an easy/cheap way to get in the game and learn about the turbo system. also would make a fun daily driver or autocross car with the fast spool.

How slow did u have to weld it? I was always told that with cast iron you had to weld really small sections at a time. Also heard of heating up 2 buckets of sand in the oven, putting the piece in one bucket and pouring the other over it to allow slower cooling. Though with a piece like that it'd be hard to weld quick enough for the sand to be used. What filler did u use? Very stock looking man, looks good.

I'm not sure what rod he used.

But.. I did some research on some 'DIY' welding on cast iron, and some people have used 70S2, and/or 309L. I haven't had much luck on finding solid information. Also, some say weld fast, and don't let it get hot. Others say to weld slow, and cool it over a long period of time. So I have no idea.

Yea, if you weld fast i think it would have to be very fast, almost in a continuous stream, kinda impractical to weld that fast imo. Yea i heard you could use normal steel filler just wondering what he used. Thanks for the info! I plan on trying to weld a vband to a turbine housing, so just seein what the consensus is.

silicon bronze filler, then put it in the oven and step it down in heat slowly.

well the cool thing about these manifolds and a lot of the import "cast iron" is that they are really cast steel. so i used my mig. this isnt my first time welding or welding cast steel. and i have never had it break. if you are welding cast iron you would use either nickel (nickle?) rod or you would braze it.

to weld the cast steel, i preheat the metal with a propane torch for a while, then lay a weld down on the hottest my little welder will go, then heat more with the torch to cool it down. i am fully confident that this technique works great and holds perfect. i havnt done much cast iron, but i know that after you weld it, you should take a sharp pointed object (punch or slag hammer) and "ping" the weld as you are heating with a torch cooling it down. let me know if that doesnt make any sense and ill try to clear it up a little.

I have heard that a lot of the import stuff is cast steel. As is our steering knuckles that I have been doing some research on, and people don't want to share info on... And that was the conclusion about normal steel filler, or the 309L that has a bit more carbon in it to help (something like that) And the heating up of the cast steel definitely helps. I did some stock intake manifolds back in the day for some domestics, and used this method.

I think that manifold is still bad ass. I was worried that you may have had the turbo flange 'plane' off a little, and throw off the elbow and downpipe angles, but it looks like it came out great.

I weld on cast iron at work. Preheat the item to 200* and get welding. Try not to let it drop past 200*. If it doesjust re-apply preheat. You want to check your interpass temps often. Try not to go too far over 300* interpass. It'll take time. When you have welded it all toss it in the oven at 200* and slowly step down the temp over 4-5 hours.

You can do this many different ways, getting the same initial result. Doing the right process the best you can will let yours last waaaay longer than the other guys before cracking.

Not saying I know all, but that's what I would do based on what I've learned at work.

nice if i knew about this in the first place i would done mine the same too instead of going with a t3/t4 top mount looks clean.

Just had a manifold done by Alex and his workmanship is good. I do acknowledge the issue with the spacing on the turbo outlet but having used other bottom mount before none of them really lined up right and require some custom work on the downpipe regardless. This manifold will require some work on the turbo elbow and downpipe but its minor issue to have a clean stock looking KA-T setup. Some pics of my on going project..
