ka-t fc
 

k so few months back bought my 3rd car 88gxl 75k og miles after owning an ae86 as my first car then going to an s13 i wanted a car that was a true sports car and wasnt a sloppy feeling pos so i got the fc, with the intentions of swapping a ka or sr

so i pulled the perfect running 13b an trans out only 75k sold the set for 400 had 600 saved bought a ka24de with all accessories and sr trans for 1k

thats where im at so far should have enough the 18th for fab work and wiring

note you are going to get flamed for this thread. but i say ROCK ON!!!!!

i have a KA24DE high comp N/A biuld in my old 240SX hatch before i sold it.

i've always liked the thought of KA20DE+T get some of those revs back but keep the superior KA head.

sounds bad ass to me you should definatlty post some pictures when you get it done
and if you need any parts pm me, like a 50 trim turbo, and anything else for a ka
my friend chris's 240 made 247 rwhp and tore it down to make more than 450 rwhp. got tons of extra parts

Was always a fan of the Ka-t, i like anything thats somewhat different than the norm. But, i dont think i like the idea of buying an Fc because of the fact its a "true sportscar" and then throwing a diff motor in it. Not bashing by any means, i love the originality factor i just dont agree with the motor you chose.

But anyways throw some pics up, its still an interesting swap :icon_tup:

would u happen to have 550cc injectors?bov? im going with a t28 set up just mild for now with fmic an run about 10 psi i drift not drag ka is a great motor and will do with the pics

thanks and yes i love ka buddy has one pushing 230hp at the wheels and higher tq plenty for me

thanks. kat is great man sr is too but ka for the budget builder is ideal for great power and good dd capable an dope mpg

ka-t ftw!!...:icon_tup:

goodluck on the project.

thanks thursday fab starts an wiring

im not neccesarily 'in favor' of piston swaps but i dont hate on them either (i tinkered with several different motor ideas when i blew my 3rd 13b :facepalm1: ) but this one sounds like a good idea! ka's are solid ass motors and like everyone has mentioned, their friggin truck motors (lots of tq). i think that a swap for a stock ka wouldnt be worth the trouble obviously but since you plan or turboing it dwn the line, i couldnt agree more with your choice. your adding weight, and its chain driven (i just have a mental block against chain driven motors, i know, its weird)but other than that i cant see any negatives; more tq, more reliable power, great aftermarket, LOTS of CHEAP replacement parts (unlike SR motors, people always getting rid of KA's). im actually excited to see how this turns out, gl man

THANKS MAN
ka trans uber strong too i ended up trading my sr trans for ka
an yes it will be boosted but not just bolt on an go good tuning full rebuild moderate power gunna shoot for 250 at the wheels and maybe later on up the mmotor build bottom end up build for more power but for now 250 is the goal

sweet, can't wait to see how this turns out.

BTW, the KA trans and SR trans are the same internally. Both are reliable up to 300-350whp...once you hit around 350, they're on borrowed time depending on how you drive it.

I like the KA, great torque and very reliable...plus there's HUGE parts availability and parts are super cheap.

Good luck with the project!

going in this sunday to begin the finish the swap

should be running friday if driveshaft is done on time

pics or it didnt happen

Pics for sure.

Succeed where i epically had no choice but to fail.....

If my town wasn't so damn gay i'd have my stock body n/a ka up and running right now....

I'm so glad i didn't do it.

I couldn't live with myself staring at an ugly ass stock body s4 sitting in my driveway for another year.

ugh.
still not done havent drove in two months
this really sucks should have been done an getting exhaust today but driveshaft shop is fuckking gay

I guess i'll be seeing more of you in this section, haha!

wow wtf didnt know you were a member so crazy

http://i82.photobucket.com/albums/j2...0323001609.jpg ran drove wont idle font know whats up

Looks good. Wont idle? Adjust the tps and check for vac leaks.


Check your pm box.

you have any more pics of this build?

what motor mounts,driveshaft did u use?

I've had three S13's all of which held up great, two o fthe cars went 250k before I needed to change motors. Did alot of drifting on the pair. For drifting the KA is about the best route IMO. Cheap to find and fix, relaible and tried and tested. If I ever swapped a motor other then another rotary i'd do a CA18DET. Small, lightweight and high revs. Mainly for track racing of course. I'd like to keep the vehicles balance. Good luck on the biuld and lets see some running footage when you get her straightened out.
The KA isn't known for TPS failures. Poor idling as in, it surges then shuts off, or does it just low idle and shut down. If it's low, i'd check your IAC which is on the back of the intake manifold. You'll need a flathead to adjust it. If it is surging then like dude said above. Check for leaks. Those rubber gromets for the fuel injectors suck. lol, so unless they are new they might be a problem.

KA-T's are beasts. I had a buddy that put one together with wiseco 9:1's, a S15 T-28, and crower turbo cams. Ended up putting down over 300 on pump gas @ 10 psi on a really safe tune.

I'm actually considering going the same route. Did you have any issues with the oil pan or subframe? Any problems besides the mounts and driveshaft?

KA's are a dime a dozen....

Me and my buddy built his KA-T for his S13 coupe for around $3k total.

$75 for a high mileage dual cam KA
$450 brand new for a JE/Eagle piston/rod combo someone was selling on houston240 who decided to go SR. Pistons were 9.5:1 CR .020 over
$120 for a full nissan gasket set from a group buy off of zilvia.net
$500 for maching/cleaning/clearancing of block, head and crank.
around $500 for dual valve springs, TI retainers, and some Crower Stage 1 cams (package deal someone was getting rid of, also going SR)

the rest was getting ARP hardware, bearings, and getting a t4 turbo mani and misc/small items. We also got a great deal on a full fuel system kit. Denso Supra pump(new), 750cc injectors(used, cleaned by RC), used FPR, used rail and -6 lines and an fittings for $350 shipped.
We went with a 2871R($750 used) and were able to get 280hp/3xxtq at 8psi on a Jim Wolf reflash(only cost us $250 on a group buy which had 500 people and we waited nearly 2months to get the ecu back from JWT), and at 20psi we did 380hp/365tq.

But it wasnt easy..... it took us nearly 6months to look for great deals on all the parts we got, and we also had friends who lived in areas with a high 240 population back when drifting was the best thing since sliced bread.

This was years ago tho.

Since then the motor made 420hp/410tq on e85 at 20psi on really aggressive timing 2 years ago and went with 1000cc injectors. since then the motor has held up to drifting and highway pulls.


But my friend wanted some more power potential and wanted more of a highway car, so he ditched the KA-T in favor of a RB25 with a large 35R 1.15 a/r pushing somewhere around 550hp on stock block @ 25psi on e85. Only engine mods are ARP headstuds and headgasket.
Just simple fuel mods, turbo mani, turbo, FMIC, DP and a Mines Reflash with SAFC(i said WTF too but it works) and MBC

Amazing!! you made your car Slower than an N/a rx7 grats

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

http://cgi.ebay.ca/1uz-1uzfe-toyota-...ts_Accessories

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!!!!!
