Hi, I am new to this forum. I've done a quick search but didnt find the answers I'm looking for.
I know SR swapping you're car is the norm, however I really like the idea of doing a mid-high power single turbo KA.
What all would I need in order to pull about 700 WHP from one?
I already know I'm going to have to tear into the engine and build the bottom end, but has anyone here done it and have a good idea of what needs done? I'm trying to get a decent idea before I start

Thanks in advance!

I'm at low 400s on pump gas alone. Without running methanol injection or E85 that's going to be about your limit, maybe into mid-upper 400s if you go V3 Crower cams and Xcessive intake manifold but you're shifting your powerband an awful lot to the right. I like low-end response for track use. I'd sit down and seriously consider what you plan to do with the car. You'd be about the millionth person to daydream up a big HP KA. Consider at this output, I'd have over 800Hp from similar output V8. You're really pushing the motor (not that it isn't capable of it) and the drivetrain WAY beyond what it was designed to achieve. The parts you're going to need to upgrade that aren't engine related to support that power level border on plain silly vs. just doing a swap for a different drivetrain that'll be more manageable at that power level, and a lot less insolent (reading V8 or RB/JZ swap here, since you're going to be replacing all of the same parts/transmission/fuel system etc to achieve the same goal anyhow.) Once I eventually convert to E85 and install the swirl-pot and in-line fuel pump I have, 500s shouldn't be a big push but I won't take it past there on this car. Besides, mid-to-high 300s is about perfect on this chassis. At around 410Hp this thing is exponentially faster and more fun than my 6.2L Camaro making about 15 hp more but with 1100lb more to lug around. And it's still streetable and reliable.

Now I've put my 2-cents in, your question has already been answered. I recommend you check out the KA-T forums or our own subform on the KA-T platform here.

Best of luck.

Welcome to NICO.
700hp is up in the range where you almost need to start inspecting the block metallurgically to ensure it won't grenade on you. Ivan at AMS did a 1000hp KA build back in the day and the first one had block failure.

I'm assuming you're talking about putting this KA in a 240sx. 700hp is a pretty stupid amount of power for an S-chassis.

Exactly. 700 hp on paper looks cool. Look up someone running a 1400hp v8. I sure don't know of anyone in person. Cleetus mcfarland has a pretty entertaining youtube channel. He broke into the 1000s in his red corvette. Look into the engines and crazyness he's gone through to get there. On his second or third block at this point. And it's a specialty piece from Texas Speed and Performance.

OP, I'd see if you can find someone with a 300 to 400hp 240 to give you a ride. They aren't that hard to come by. See if that doesn't change your mind about how much you 'need'.

And SR swapping isnt the norm anymore. It was for Import Tuner back in the 00's. Most swaps nowdays are RB, 2JZ, or SBC.

Not that hard to come by. Still a silly amount of power for an S chassis and a lot of money to get there.

What would your recommendation be? Just build the KA to 300-400 hp, LS swap, SR, or what?
I'm pretty new to the S Chassis

What are you trying to use it for? Daily driver cruiser, the KA is perfectly potent enough to make a very fun 240. Id even argue light track duty like I'll be using it for.

Trailer queen drag car? That's a different story. 2JZ or RB would make for a good fit. High revving and billet block options with stout transmissions.

The drift community has embraced the LS. Torque at idle and a broad powerband makes for a pretty tough to argue against powerplant. And parts are cheap while pulling 500-600hp NA it'll stand up to that kind of abuse well.

There's no right answer, like I said, try to find someone with a built 240 to give a ride. These chassis are light and tossable and don't need gobs of power to be very fun and very competitive.

Awesome thank you! I plan on cruising with it and once I figure out where I'll be located, hopefully theres a good track so I can drift it. I think LS would be my best bet.

Now I'm sure I could go search and try to find a good answer, which I will, but any idea how difficult an LS swap is in an s13 or s14? I'm sure by now there are kits for it

Cant speak to the drift thing much but 700whp is more than you'd need for drifting even. That's pro level, sponsors pay for stuff level there.

Id leave the car as is for now and enjoy it. Replace the bushings with energy suspension or something comparable. Look for a good r200v diff and j30 axles, clean up all of the stuff that may need replacing on the car regardless of your final powerplant. I had tons of fun in my 90' hatch with a stock KA24DE swapped in and freshened up chassis/drivetrain.
