slower (until a turbo gets thrown on)....probably. but having the peace of mind that you can actually use the upper half of your rev range without wondering if "this will be it"......can you say p r i c e l e s s ? ?

belated congrats on the swap, now buy a turbo and let the fun begin

wondering if this will be it when using the upper half of your rev range on a 13b? seriously?

Im all for piston swaps dont get it wrong and i know a few guys with turbo ka-t's but they aren't faster than a boosted rotary...

Imo you have a sports car when make it go slower cause a motor hasnt been done before

yep, blown 2 13bs in the last few years......both done between 5500 and 7000 rpms....

who said they were....?

....i dont understand your language sir.

if you're blowing engines that quickly it sounds more like an owner issue. There isn't a time i drive my car and DON'T go over 6k rpms, still runs excellently.

no, that just means you're not running enough boost haha.

Learn to tune. Then learn how to turn the knob on the boost controller.

You were obviously doing things backwards.

Slower...? If the engine he pulled was an NA engine, then chances are the car is going to be a little faster. The stock KA has 155 hp and 160 lbs of tq. An djust minor bolt-ons wake that engine up rather well...? Not to mention for drifting like I said, that Ka is a much better choice due to the tq it carries. He pulled an S4 engine out, aren't those abotu 140 hp??

doesnt matter how good the tune is, if you say that you dont have at least a little fear in the back of your mind when your boosting over like 14psi on a 13b, you're either lying or have watermelon sized balls. or youre running some sort of AI or fuel other than pump gas haha. either way, my comment was a hyperbole and was meant not to bash rotaries, i love them to death (obviously or i wouldnt have one any longer) but was more of a credit to the KA. its seriously a bulletproof engine.

agreed, but at the same time i dunno what the weight differential between a KA24 and a 13B is but im sure the 13B is lighter by a fair margin. in any case, an fc with a stock KA24DE may be slower than a stock NA fc, but like i (and you) have already said, if you threw a couple bolt-ons or a turbo) its way it would easily surpass a stock NA fc (or Tii for that matter) AND have the added benefit of being able to take a crap ton more abuse. PLUS, the low end would be much improved (at the loss of some of the high end of the 13B).

Really? With a turbo? Seems doubtful when running correctly...

I never said it was to bash rotaries. And everyone makes mistakes with tuning, it's all about learning.

I will agree with you on KA's though. The stock bottom end is bulletproof to about 400hp. Even then, all you need to do is get bearings and rods and its clear sailing from there.

And a N/A rotary doesn't have anywhere near the power of a KA. N/A's only had like 140 from the factory 20 years ago. Assuming he even had a rebuild and power mods (header and safc), the most hes looking at is like 145, maybe 150. The KA does that stock exhaust, stock computer. Slap on a cheap ebay T4 or a S14 T25. He's easily looking at at least 250.

Don't get me wrong, I love the rotary. But the KA is a perfect power plant for what it costs.

Yeah, the Ka is a pretty heavy bitch.

yea, thats why i said that although it may make more power and tq, its doubtful that an fc with a *stock* KA will be faster than a stock NA fc (because of extra weight).

but yea, KA-T is an awesome selection for an fc. good, reliable power, easily and CHEAPLY upgradeable, simple design, etc etc. id do a KA-T fc over an SR20 fc any day just for the cost differential. now an rb26 is another story haha. something magical about having those extra 2 cylinders haha

The Ka is only about another 100 pounds MAYBE. At a difference of about 20 hp i'm sure a ka powered FC will take off on a 13B powered fc ( na of course). So once agian, I don't see the aurgument here. The Nissan 240sx weighs around 2700 where the fc weighs about the same. I've races NA fc's before and I get away from them. SO I mean. unless the gearing is that much different I don't think it will be slower. Not to mention the extra weight of the Ps/ tower and such. all that extra metal adds up adds up fast.

true, true. i wasnt really sure of the weight difference, just knew that 13B had to be lighter.

My S5 n/a will straight walk KA24DE All day any day I've got plenty of 240 friends that will vouch for it, its not about the peak power its about power band

The KA24E is 140 hp The DE is 155 hp, S4 is 140 hp and the S5 is 160 hp

OmgitsRAZ n/a vs n/a yes a rotary will walk a KA

I can appreciate the level of work going in to a swap like this But just IMO Putting a KA24 into your car because its cheap is the wrong way to go

*TOUCH* I know plenty of FD's up here running more than 14psi and going to the track every weekend (Circuit) And not blowing up


If i was to be cheap and put a piston motor in my car id go with the 1uz and an R154 trans Otherwise it would be a 1jz all day

Good luck with the swap I hope it turns out good for ya man Post pics when done

That's actually the direction I'm going. I got a 1UZ for cheap from a friend when he crashed his moms LS400. Planning on picking up a bw s466 later in the month for it.

just keep it in the 240sx

I've been looking at 00-04 S2000 shells. Give the corvette guys a hell of a scare when they hear the V8 rumble from it. :lol:

My FC is WAY too far away to make anything happen with it right now. It's getting put on the backburner for a few years while I save up cash for a real build.

ya man they go for around $400 up here

that bellhousing + an R154 trans and you are laughing Super reliable

Did you guys fail to realize the torque curve of the ka? Have you seen what they can do turbocharged? 300whp reliably just with an mls gasket and some arps.

Fully built, 400+capable. They are a good motor and cheap if you do happen to grenade one. Nobody ever says "damn, i can't find a ka block anywhere and the ones i do find people want an arm and a leg for".

People are giving the things away for FREE.

That's enough reason to swap one.

dude so do I, but that doesnt mean that the fear isnt there. i didnt say that rotaries blow up every time you boost them, i was saying that with a rotary there is always at least SOME fear when your pushing any significant amount of boost (although admittedly its a little different of a story with an REW)

AGREED. altho i do think that the KA is probably the best 4 cyl swap (and myabe the smartest) for an FC, the jz is my favorite piston swap option, and the 1uz sounds bad ass. i have a buddy that has a 1uz mkiii supra and its bad as hell, it would be a hell of a good choice for an fc too.

my point exactly. nissan ppl literally just junk KA's for SR20s, you literally can get one for free.

:awesome:


One of the few engine swaps I'd actually do in a FC. Those motors are kickass swapped into MKIII/IV supras too.

Banter like this is the reason this section grows at a snails pace. Rx7club ftmfl.

NO ROTORS!!!!!

Haters gonna hate.

hate hate hate hate hate

Ofcourse. You're my biggest fan.

Lol. I can see you saying shit in your sleep after viewing my build thread.

"you're doing it wrong"

"you're doing it wrong"

"you're doing it wrong"

Haha. It's all good. I take it with a grain of salt. There's some people who will chew your throat out over some of the shit i have done and will do to my car and i just laugh because those are the people who are going to die of a heart attack at 30-45 years old because of a car.

"they" hate you as much as they hate me though. You drift too!!!!!
