Don't sell it. Save and get another. And even so, what's the sentimental connection you have to that particular car? If it's a POS, as all SOHC powered 240's are, get rid of it and get what you want.

Why get rid of it when I can just get a DE?

keep the sohc we just took the dohc out of my buddys car and converted to sohc holds more boost and is way cooler to beat on mustangs with the single slammer

but if you wanna swap just do a ca or something because by the time you build the bottom end and turbo it you could have a real swap

im in the process of getting the last couple parts for my swap and then the rb20 is going in

Maybe I will keep the SOHC. As you said, it holds more boost, which is the one thing I really need. I just need to find a website that has the parts I need at reasonable prices. What I'm looking for right now is maybe a short shifter. If I got a short shifter for the DE would it fit the E?

keep the single till it blows then swap it out for whatever but imo the dohc swap isnt really worth the swap either

Let's see here...daily drive a boosted SOHC or spend $3k on an SR? I would stick with the single cam, they can be had very cheap (You could get 20 of them with $3k) Rebuild it, boost it, take care of it and have alot of fun with a motor that holds boost well and is cheap to rebuild. With the $3k you would spend on an SR you could rebuild your motor, boost it, and get coilovers....Unless you plan on going with insane 500whp monster build I would stick with the SOHC

Sohc ftw. That's what I plan on doing. A nice reliable fmu setup and I'll be making around 200HP. Plenty for me until I get some experience under my belt.

Maybe not as bad as others but in comparison to any other motor possibility they most definitely are.

Say you paid $3k for for the piggy you have. A DE powered Chuki can be had for not much more. Say $3500. Sell the piggy, get a chuki for $500ish more. $500 Nissan installed everything working > 15 year old done DE swap. That's why.

Or I can just keep the E, save up for an RB, buy RB, wait till E blows, then have RB swapped in?

If you are gonna do all that you might as well buy another shell and work on it in the meantime. If that was the intention all along why didn't you put that in the poll?

Well it was one of the couple ideas I had for my car. I've been deciding what I am going to do motor wise for the past few months. At first, I thought SR. Then I stopped thinking about it for awhile. Then I finally came on Nico and started learning about the car. I finally thought about the RB. And then I had the KA DE idea. Now I'm just torn between ideas. Some of you guys are telling me to keep the E. My friend Carlos told me to just keep the E and save up for an RB and then buy the RB when I have the money and just study it until the E blows. I would love an RB, but I don't have a job. I am, however, gonna look into a job at maybe Burger King. I just really don't wanna put my hair in a pony tail...but at the same time I don't wanna freak customers out by making them thinking I'm some sort of metal-head psycho path that would cum in their food.

check my build out search for true pig build
I haven't dynoed it yet but I'm guessing i'm at the 250rwhp range.

you're fifteen and money is tight, I know exactly how you feel. Stick with the sohc with a low boost setup (200rwhp) with an fmu, cheap and reliable. At your age and income, you'll be thankful for any kind of boost. I would rock the ka24e-t and drive it to the ground then when you're a little older and making more money you can consider other options like the DE or possibly a rb, sr, etc.

Plus if you blow the sohc, it was just a high mileage POS and you could get another probably for freeeeeee!

well I dont see how the sohc-t is inferior to other engines, except most definatly ls1, or rb25-26, or 2jz. But yeah others like sr, ca, de, if built right will out perform all of them except the de, ie same engine just improved.

does it say on the block "THIS ENGINE IS A GIANT PIECE OF ****! DONT MODIFY ME!

unless there is some hard evidence that im missing that makes the sohc so horrible try to keep them to yourself. all of the choices can be fun depending how far you go with them

the sohc will do fine and keep up with a stock rb25/sr pretty easily. The single cam from what I hear loves the boost just as much as the DE and you can put some good numbers down with minimal boost on stock internals. A t-25 off an essar with the stock 7 psi wg setting should give 200rwhp on a sohc easily.
