hi, I have searched this Forum and FOund nothing that gives helpfull information about the swap. INstead Ppl are arguing its a good motor, this swap is not worth it etc. LET ME CLEAR THIS UP. I AM ASKING FOR HELPfull Information about this Swap. " I DONT WANT this THread to Get into a Debate" SO Plz

1.) Dont lecture me about the v8 swaps, 20b,13b,12,13bt 13re Swaps, or any other sr20det, or ford 2.3 or nissan vg Swaps,

2.) I dont want you to tell me that this motor is not worth it. I dont want to get into the details about the advantage or Dissadvantes of this Motor.

3.) If you have nothing smart to say plz Dont Contribute.

4.) Again no debate about the other Swaps.

5.) all i want to know is Hows the clearance at the Bottom, wut do i have to cut, xmember ete, hows the tranny sits, Coustom brackets, and Stuff.


PLZ LET ME know about the technicall difficulties in this swap and it would be of great help if the actually owners of ka24de in a FC3s or 2ndgen give me some pointers.

thankx.

ka-t?

Well, youd most likely need a standalone ECM (megasquirt would be my reccomendation) and some way to connect it to the rest of the drivetrain - a nissan tranny would most likely be able to be bolted to the underside of the car with a crossmember just fine. And of course a custom Driveshaft.

And, of course, you'd have to run all the lines, hoses, etc to the radiator, fuel lines, wiring, blah blah blah.

Custom mounts would be a matter of fact for such a swap, and youd also probably need custom exhaust, dunno about an intake. FCs have a ton of underhood area but I dont know how the geometry of a KA24's manifolds would fit in there.

Also, just as a statement, the KA24D and DE are great turbo motors with simple mods.... IVe seen buttloads of power on them with holset and hybrid garret turbos - dont let anyone give ya **** over it.

Keep us posted about the progress

Bigzgvr4

ya i am going Ka-t, The whole setup including custom turbo kit/motor/tranny would run me about $1100-$1200.

Bigzgvr4

why would i need to Run a Standalone, can'nt i just Use the Ka ecu, and use Greddy EMange as a piggy back, I am seriously looking into Mega Squirt. Wut about the Oil Pan will it clear the underneath Frame. inthe Engine bay.

omg.. I just typed all this out and it didn't post and deleted it all.... try number 2...

ok... wiring...
You don't need a standalone...
You will need to give the ecu, fuel pump, etc power. On the KA harness it is out near the pass. side headlight. There are 2 harnesses there that would need to be spliced into the rx7 harness. Now you need to go under the dash on the KA harness near the ecu plug, there is a plug there that has the gauges signals, you will need to splice them in to get the rx7's gauges working with the ka's harness. I'm not sure if the ka's gauges get the same type of voltage that the rx7's does, but that is the last thing you need to worry about. You will also need to splice in the ka's lower haness (alternator, oil pressure sensor, battery, tranny) check out www.heavythrottle.com for the wirirng pinouts for the ka's harness under "sr install faq".

Exhaust:
the exhaust is on the left side near the steering shaft. You will need a custom exhaust since it is opposite of the rx7.

Intake:
The throttle body is on the same side as a n/a s5 rx7 (right), but facing straight ahead, which makes intercooler piping easy.

Intercooler:
A 240sx intercooler would most likley fit since they are pretty close in sizing. You will need to make some cuts to make the intercooler piping fit.

Engine mounts:
You have some options... either make some engine mount bracket adapters, or make the 240sx subframe fit (would most likley need some cutting/welding/drilling). If you use the subframe, then you could mount it right up and hopefully the tie rods from the 240's rack fit, or you could use the rx7's steering rack on the 240's subframe, which would probably be the best option. I have measured for the sr20 before and it would fit, so hopefully the ka would also, but I dont have any ka's at the garage to measure off of. We were going to do the sr swap before, but the customer backed out. The KA has an iron block, so it is heavier than the 13b, you will need some beefy suspension and take off all of the emissions, a/c, etc, and relocate the battery to make up for the weight up front.

Tranny:
You will need a custom tranny mount bracket and a custom driveshaft. Make sure the shifter ends up in a good spot. Other than that it should fit. The rx7's tranny and ka's tranny are pretty close in size.

Power steering:
I think the pump is on the same side, but I'm not sure. I can check. You would probably need custom lines either way.

240sx

damn where are you finding a motor/trans and turbo kit for 1100? my s13 needs new motor and turbo power.. anyways check out how people put sr20-s in fc's if an sr will fit a ka will be the same. ka-t's are real nice motors, good luck

FCdemon

I know you specifically asked not to get this kind of advice, but I can't help myself:

do yourself a huge favor and just buy a cheap 240SX. they are fun cars, and look good too.. not much reason to swap into an FC.

Bigzgvr4

thankx Alot for the info, I really appreciate it. as for the gauges, iam going to use autometer every thing, I got a good hook up from Keystone. oh and i am not going to Use A/c/Cruise and other Bullshit, i do need a power steering though.

wut would u recommend Using the 240sx subframe or making coustom brackets for th engine.

agian thankx for the help.

Bigzgvr4

the motor tranny and harness, ecu are cheap, you can get almost anywhere for like no more the$500.00 for the complete setup.

and turbo t25, for $100.00, manifold $125-$175.00 Interecooler Front mount $100-200 or side mount for $50.00 pipping extra $150.00 and ur done.

Bigzgvr4

why dont you buy my Fc for $500.00 with a 13b and tranny in the Car. I have been trying to sell it for the longest. buy my car so i can buy the 240, if not then I should Say STFU but i am Not going to Be Rude.

so never mind.

Hmm.. kinda a neat swap. At first i was thinking, 'oh god'; but your putting a turbo on it so it should be pretty cool. I use to have an altima with a ka24de, and i thought that was a pretty good engine. I drove mine to 200,000miles, and it was running strong when I get rid of the car (which was in a accident and was totaled). I beat the crap out of that engine, too. I ran that car at Gingerman raceway with 160,000 or so miles on it, bouncing it off the fuel cut off and the thing never skipped a beat. The only thing I ever had to replace was the ignition coil, and the valve cover gasket.

I wrote about some of my problems swaping in my s2000 engine, you can read about that by clicking the link in my sig. The biggest problem with swapping in inline 4's is that they are so much taller then the rotary...

FCdemon

If you can't sell a FC with motor for at least $500, it must be a real pile of ****. Have fun making your POS slower than stock!

good choice of motor. small and tq happy!

RX7ROTOR

Great motor. The record for the motor now is 718whp.
I have the KA24DE motor in my car. The valve cover gasket crapped out on me too but it only cost $28 from the dealer to fix it. The stock ignition coil should hold up to 400-500hp. Gets great gas mileage unless you floor it, passes smog without a problem.

If you get the motor off the 240sx it should be around 160hp. The stock motor can handle a 75 shot of nitrous as long as you got the fuel covered. If you're going to boost it get rid of the crappy pistons.

They guy's 240 your are talking about with 718whp is IVAN of AMS (reputable company in Chi-town) he actually will have more power very soon, he got the wrong turbo combo, so hes switching turbos and going for 800whp.

Also the stock coil on a 240 is acutally only good to about 350hp...then people usually switch over to an msd coil...which is good to about 450hp without a ignition booster like a MSD SCI box...btw...just a question...does your RX have a KA in it, or your 240?

And BTW...a stock ka (brand new) was 160 crank hp..which is between 120-140whp...depending if your motors a freak or not.

RX7ROTOR

I got the hp info from the same website as you. You're a member there.
I used to have a MSD system. I had an internal coil so I had to have my distributor cap modified to work off a MSD blaster SS coil instead of my stock coil. At 2750rpm to 4000rpm it felt like the car was more responsive. No I don't have a RX. My car came from the factory with a KA motor. The 240 also shares the motor with the altima from 93-01. The compression is a little bit higher on a 240 motor than the altima motor. On the altima it was 150hp.

Bigzgvr4

Its not a Pile of ****, with ALmost Evey thing Converted to T2. ITs Cheap Ppl like you with No money, but dreams. Keep on dreaming for you 20b,13bre, and when you finally get it enjoy it for like 3 weeks and then Its Broke again, Oh i know the water seal blow,no wait Apex, nowait Rotor seized, no Wait iam Getting 8mpg, and ca'nt drive it Daily cuz i voted For Bush, and look at the Gas Price. HOT DAMn. *** HOLES LIKE YOU. ROCK ON "DUDE" ROCK ON


I avoided this type of Conforntal Conversation, but I guess SOme PPl Have Bigger ******* then Other and want to SHow OFF.

Drift King i saw your Build on kat.org By any chance Can you or some one u know make mOunts For the FC, I like the FB. hows the GroundClearance.

driftking777

iTrader: (1)

oil pan sits exactly even with the FB steering arms...And unless i had an FC laying around, and a spare KA they couldnt make the mounts...however...If your willing to pay, I might have a friend with an FC that would possibly loan his FC to me to get some mounts made...but it isnt cheap.

driftking777

iTrader: (1)

lol didnt quite have to explain all that to me...i know...and i thought you had an RX with a KA, thats what i was wondering, since you have a 240...well of course it came stock with a ka...lol

RX7ROTOR

I don't know why people are complaining. The KA24DE is a good motor for boost or NA. Just have to get the crappy pistons out.

I'd rather be rocking a FC with a KA that gets high 20's mpg and whoops *** than a FC that breaks down, gets horrible gas mileage and can't pass smog at all.

Bigzgvr4

PM me More INfor Plz. On how much its going to Cost. I really Like ur MOunt Setup.

The mounts that i had made were $750, that was motor and tranny mounts. Everything is very solid, but is made with poly bushings so the motor wont rattle your teeth out. I had my motor specially fitted in there to sit a certain way for my likings...centering the motor would be easier and quicker to do.

However problems that you would run into for having me make you the mounts. #1 me finding an FC
#2 would have to find a way to have someone Weld the mounts to your car (mine are welded to my frame, but can be taken out...if needed i can take more percise pictures of how they come apart.
#3 Money...i would honestly not go through all this trouble for free, becuase i would have to use my motor for the mock up. along with my friend doing it for free...but thats another subject all togather..

your best bet is to find a fabricator and just use my design and have them build it for you..it'll be cheaper.

if you have any other questions dont hesitate to ask

blwnrtr93

you're doing the exact opposite of the swap that i am considering. first off even though rotary engines are a little tempermental i'd still rather have a 13b turbo than a ka24. so my swap is going to be a 13b turbo from a 2nd gen into a 1990 240sx... my $2000 total project. my fd ate all my money so the 240 will be seeing alot less than originally planned. good luck with your swap.

mmjb

Hey nice to see someone else wants to be a pioneer also. I am also putting a ka24de in my 2nd gen rx7 TII. Here is what i have encounter and done so far.

1. before you think about engine mounts you want to use a lift to test fit the motor. The motor will fit fine with a good amount of room. I put the motor as far back as it would go, and as low as i could w/o getting the oil pan to close to the ground. This will help weight distro and handling.

2. Now the oil pan is tricky. if you put the motor up front close enough the oil pan will fit w/o modifications. Otherwise you're gonna need to make your own oil pan and pickup.

3. The ka24de tranny fits nice inside the rx7 housing. By setting the engine back as far as it could go the shifter fit right inside the rx7 shifter hole.

4. As far as the driveshaft goes, the ka24de driveshaft its smalller than the rx7. Your going to have to make a custom driveshaft or use a 240 differential.

5. With wiring your basically going to need a standalone. I'm using megasquirt. Your going to need to get a 240 gauge set, and your gonna need to have some knowledge in wiring to do this.

----------------------------------------------------------------------------------------------------

Know for what i have done so far.

1. Engine wise as i said b4 i set it back and low. While it was still on the lift i used cardboard to template some engine mounts. I am going with solid mounts. I will post pictures when i take some for you.

2. For the tranny i was able to fabricate some mounts that bolt to the stock rx7 tranny mount holes.

3. Wiring, i'm using megasquirt as my standalone. I actually pulled all the wiring out of my 7, and rewiried everything in wanted to keep (including lights, power windows, mirrors, etc.). I made a custom dash also, so the 240 guage pod would fit.

4. With the engine way back there is a **** ton of room to v-mount so look foward to that.

---------------------------------------------------------------------------------------------------

now for what i still have to do.

1. I still need to make a custom oil pan.

2. I still need to get a custom driveshaft built.

3. I need to finish wiring

4. I need to finish the turbo setup

So right now i have not been able to run the car and see if everthing is butter, but hopefully it will be in the near future. If there is any other questions you wanna ask or pics you want me to take just ask. Also let me know how your custom job is coming tell me, cause im still not finished yet :P
