Ka24det FAQ

[upSLIDEdown]

I've never read about it here but I saw Greaser talking about it on KA-T.org. I think he's a member of FA also. He does it on all of his motors now. He drills a hole in the block, welds a AN fitting to the block and uses stainless lines. This alleviates fixing lines and checking them for leaks. It's also more resistant to heat, oil, etc. It also seals easier and it's definitely gonna be higher than the level of the oil in the pan.

[NismoSilvia270R]

it was in a magazine tech article. it had a silver mkiv on the cover. one of the more ricier mags

edit. modified mag around jan o4.

[nightwalker]

Thanks guys, I'll go bug Greaser at FA.

HKS Super blow. Great for open atmo. bov. seals nice and tite at idle no staling once in a blue moon a little flame (it is a push/pull design bov so T off one vacume line to the big nipple and the little nipple on the back side.) Thou most of the HKS bov you can run open atmo. with no problems

Blow by MAF had great throttle response, nothing negitive

Pull Thru MAF recomend 12-18" of pipe from maf to turbo, great idle, perfect fuel pressure reading

Recomend changing out the pvr valve, seen a few of those go up which in turn less lifespan on piston rings

Ka24de sick motor!

[SpdElemts]

I dont know if this has been asked already but can the 95-98 turbo kits fit the 91-93 s13?

[DRFT180]

What about the SSA manifold? It states it's for the 94+ kade, will this manfold work on 91-93 ka's??

[Jeff240sx]

It'll be another week or week and a half before I can commit a couple hours to these threads. Until then, keep adding info!
For the two above. 94 = s13 convertable = s13 engine. Now. SSA sucks, their SSAutoCrack manifolds suck, and if they don't realize '95 is the beginning of s14 with a different engine bay, or that by including '94 it infers fitment to '91+, they're retarded. I'm sure someone would have corrected them by now...

[TurboB15sentra]

Here's my ideal KA setup.. I'm actually building this right now..

S13 KA24DE motor
Arias 8.5:1 pistons
Pauter forged rods
JWT cams/springs
ARP studs
metal headgasket
Custom sheetmetal intake manifold
Garrett GT30R (.82 A/R)
Custom equal length stainless manifold (316L schedule 40 weld L's)
3" dp and exhaust
Enthalapy (formerly of Secret Services) tuned ECU
72lb injectors
Z32 MAF
Custom billet twin feed fuel rail
Twin Walbro pumps (just in case.. )

All the other mods... intercooler, piping, blah.. blah.. you know the rest..

Travis

[AlligatorBling]

a quick question.... besides upgrading the fuel pump, injectors, ect, is there any major change you have to make to the car after installing the turbo, such as ECU settings ect?

[kandyflip445]

Yes, along with what you said you should have a way to control the fuel. Such as an ECU (Enthalpy, JWT, etc.), S-AFC, stand alone (AEM, Tec3, etc.). The ecu and stand alone will also control advance and retard, along with higher resolution, so they'd be the better choice.

I don't realy think that Scott's tuning ability is above Clark's.. Seriously.. think about it. Clark has been tuning Nissan cars/trucks for 20 years. They do work for Nissan Motorsports and Nissan Corporate.. at least a few projects a year that no one even knows about. Clark's knowledge in camshaft development and engine tuning theory is phenominal. I talked to him last week about the big hoo-rah on Fresh Alloy about the JWT versus Enthalapy ECU comparision.. He laughed about it.. and said.. well I would hope that any competant tuner would be able to get more power out of a given setup if they sat there and tweaked on it. Also, not every setup is the same.. Different bends in piping affect flow over the MAF sensor... differences in fuel pressure.. timing.. etc.. All of this stuff adds up.. so Clark DOES tune conservatively. I don't blame them.. When you tune to the edge, and mass produce it.. things can go wrong in a hurry. We're not just talking about a few ECU's here and there... JWT turns out hundreds/thousands of these things. Liability is a big issue.. so, it pays to be conservative.

And I'm NOT taking away from Scott's tuning ability... He's very good at what he does. But, to say that he's better than Clark... just isn't true. Matter of fact.. Scott is going to help tune our newest 500whp Spec V project. Since our customer lives in Tampa.. this will be convenient. If I were closer to CA.. Clark would be helping. I trust BOTH of thier tuning ability.. But to say that one is better than the other.. just isn't fair.

[240SXS-14]

I was wondering if anyone knew what mods to do first on my engine. my car is 97. Someone told me that I need to get a timing chain guide update done and the valve adjusted. Is that normal for an engine with 64k on it?

please help

[240SXS-14]

AEM just came out with their new stand alone plug and play computer for the S-14. I have it on my list of things to get for my car. I plan on turbo charging the stock ka24de. I have seen them handle 300hp to the wheels no problem with high mileage.

I am not sure what size turbo I will go with yet but I want to run an external waste gate. What is a good turbo to start out with?

[Jeff240sx]

Oh my god. I didn't just read this shit on Tampa Racing. Now that you're on my forum, the FAQ will not turn into a debate. Make a different thread if that's what gets your rocks off.
Scott said there were only slight differences in a chip he'd ship out versus that ecu he dyno'd. 40hp is not "slight differences". 10-15.. maybe 20rwhp would be a margin of safety. 40rwhp gain over JWT is rediculous.
You brought up this camshaft design shit in TR too. Here, again, we're not talking about camshafts. Or who gives better blowjobs. Or who has the darker eyes. Wow. He can design a cam. But apparently can't or won't tune an ecu for power. 10.5:1 from the JWT ecu I got can be construed as "Safe Tuning." To me it's a waste. A waste of gas, a waste of power, and a sheer waste of money. JWT has no customer support, and charges to retune. Scott is readily available, remembers who he's talking to (as opposed to my "Hey I have a problem." "Ok. Open the ECU and tell me the numbers." "Ok. I got the numbers.. 46xcx20dcxz." "Who are you?"), and doesn't *afaik* charge to retune. I don't care about how many ECUs they sell. Maybe they forgot what customer service is, or maybe it's just another case of "Bigger isn't better."
How about the use of a Cobra MAF? It's a ploy for JWT to make money imo. There is no reason to use a shitty MAF like a cobra, which a) is hard to make piping for, and b) maxes at 350hp. How do they get it past 350hp? By using a splitter in the ecu. When a z32 maf is great to 545hp, and the ecu reads true, why write programs and only sell the cobra maf? $$$.
So here we have price. Scott wins. Customer service. Scott wins. Power. Scott wins. Fuel economy. Scott wins. About the only thing JWT can be thanked for is pioneering this.
And in a year, if someone bothers to seek out and tally the blown motors attributed to Scott and JWT, I will bet $5 that the two ecus will be within 10% of eachother. Most people blow their motors due to a corner cut. Not the ecu program. So losing so much power, so much gas mileage to prevent only a handfull of ecu-related motor deaths is not worth it.
How about this. If JWT is great, why don't they come out with a 2nd program? One oriented towards power and economy rather than safety. I didn't half-ass my setup. I don't want a program written for those who do, and I want my 40rwhp back.

I'm sorry what I posted upsets you so much... I thought it was rather positive for Scott and JWT both. I am not "up JWT's ass".. matter of fact.. Scott is going to be tuning a few ECU's for me.. and helping tune a turbo Spec V for me as well. I am simply saying that the tuning ability of each of these people.. is great. If that upsets you so much.. then you need to have your head examined..

And you don't need to play "big bad moderator".. There's no need to disrespect me just because you have those powers. I didn't attack you.. or your credibility.. so I don't appreciate you doing it to me. It makes you look ignorant, honestly.

[pr240sx]

I searched everywhere here on Zilvia and havent found this info.
I finally purchased a turbo (T3 from a volvo 740 AR 42 compressor and AR 63 exhaust) and now I am searching for manifolds

I just want to mount my turbo so I dont really care (dont know the advantages if any) if its top mount or bottom mount. Also I have read about all the SS auto crap manifolds and dont really want to throw my $$ away.
I checked with boost desings but their answers dont really tell me much about fitment.
The project is for a street driven car, no track use whatsoever, pump gas and a 7~10psi max (but looking more toward a max of 7 psi).
I plan to install 370cc injectors, walbro or 300zxTT fuel pump and tune them with either an SAFC or Emanage (even a Accel DFI or FAST computer)
Looking for a budget setup that tops 1500 or so.
What do you guys think?
thanks
193 DOHC soon to be turbo

[blazn240sx]

what u think i can make
bottom end: crower rods, 9-1 supertech pistons with swain coating, slight bore 90mm, and crank and everything balanced
head: ported intake manifold, supertech valves, supertech spring and retainer, altima intake cam and 91 240sx exhause cam, 72lbs msd injectors, jwt fuel rail, aeromotive fpr, cobra mafs, jwt ecu, also a cometic head gasket
turbo stuff: t3/to4e, jgs exhaust manifold, and apexi gt spec intercooler

[koukipurples14]

okays here my input im not saying that ka24det sucks cuz i was in the process of doing it myself but i sold it cuz all my friends that do it have it for about 2 weeks then the block blows up and not their not boosting its stock 6-7 psi of boost so im just wondering what do u need to do to have a reliable ka-t? that can put 220 hp out and can b daily driven?

[turboeic]

Tune it. Its all about the For me I don't think a AFC will do it. There's some guy on ka-t.org pushing I think 340 at 20psiwith no internals. So you want reliability get a tune.

Parts are probably going to fall apart. They do not even have KA stuff in the pictures.

eBay kit. wouldn't try it...

[JuniorsSr]

I have s14 turbo/manifold/370 injectors/ front mount/piping/255 walbro/z32 mafs still need safc/2 this is for kade I'm only planning on 230-250 rwhp do I need to change head gasket or will it hold up? Thanks

[wsmiteh]

Want to do some work on a ka24de valve cover (polish, paint, w.e.). Do any other vehices with KA's have the same valve cover as a 97 240sx? Of course I cant an s14 at pick and pull but thought I could potentially find a cover for the same engine! I know s13 ones are different, but I was thinking SUV's and shit....

[Jeff240sx]

Big bad moderator? Your lack of control (and others who kept up the arguement) sent Scotts harmless post down the shitter, and Scott locked it. I don't want this crapped up with bullshit until I get free time and can prune/add info.
I'm not upset, other than the fact I already brought this book-of-a-post up on Tamparacing, and it apparently didn't even make you think about it. You are simply posting the same stuff you had before. The only thing in my post that can be construed as "disrespect" is when I said "We aren't talking about camshafts.. or anything else. Simply ECU tuning here." Clark may be a great guy. That's well and fine. He may design badass cams. Hell, I'm running JWT cams and waiting for my cam gears. The cam gears could be a bit better, ala AEM with sliding adjustment, rather than tooth by tooth, but it's not a gigantic deal. What is, however, is the subject of the debate, and the 40hp gained by an ecu that "only has a couple changes over something I'd [Scott] would ship out." I feel that I provided enough first-hand knowledge and examples in my post. And since you're friends with Clark, why don't you ask him to make better tunes. Do you know how much money they would make by offering a "race tune" or something along those lines. Pick up 20hp, and still have a 20hp safety margin. Slightly more agressive timing. I understand that JWT was the first to write these programs. When the first SR swaps were being done, JWT KA ecu burn to the rescue. When the first turbos were blowing up KAs. JWT ecus to the rescue. But to have what seems to be a dinosaur of a program running these cars that are no longer shady-tree mechanic turbo kits. We now have 10 turbo kits. 3 or 4 equal length manifolds. Basic ways that are tried and true to make power. JWT could take a couple people's cars and write better programs. Put a warning on them that says "Should only be installed on well-working motors, not responsible for blown motors, ect" and sell them. If I didn't live in Tampa, and JWT came out with a new program, I'd be the first to pay $200 or $300 for a reburn that would net nearly 20hp.
I didn't mean to come out on the attack, and in my eyes, still don't see it that way. I was simply saying that this needs to be in a different thread if you'd like to debate the merits of JWT and Scott. And as you can see, I'm the first to debate someone.

Hey wassup guys, still new to this engine stuff but not to the whole 240 scene. I was going with a ca18det but a buddy of mine made me realize that the ka has better torque. And don't we all love more torque. So I start doing my research on what would be needed to be done to get 300whp. From what I found, I understand that I would be good with rods, pistons, turbo, ecu, standalone, fuel pump, catch can, injectors, z32 maf, and some cams. Please let me know if I missed something. Now I was wondering which z32 maf. The turbo model? Again I don't know much about this! I know it's the upper. Upper, plenum, turbo? or Upper, plenum, exc. turbo? Pipe or no pipe? I did a search on http://www.car-parts.com and got different options which I don't know much of. I also don't know which pistons and rod are good. I found some nismo pistons and rods don't know if those would be the ones I need. I know which turbo to go with I believe it's a t3. I'm a little confused with the whole standalone thing. Sounds like the standalone is like a workaround the ecu, am I correct?

Please only reply with helpful tips!

you need to research more before even thinking about putting a turbo on your car. You cant get a ecu AND a standalone....and stay away from standalones until you have some tuning experience

[woodysmom]

i was reading your stage information but wasn't sure whether stage 3 should require a build up.

i'll be running 50lb injectors/to4e turbo/z32 maf/enthalpy ecu - not sure whether my engine needs a build up for 10-12 psi. thanks

I wasn't trying to be disrespectful to anyone.. That was never my intent.. Go and read my post.. It's very neutral. Which is why I got upset about your post after what I posted. I wasn't trying to argue with anyone.. just having a discussion.

I agree, that JWT is very conservative. However, just keep in mind, that we are talking about 2 different flow meters.. which respond dramatically to bends in piping.. and airflow. The Cobra MAF is crappy.. I think the reason they chose to use it.. is because it's fairly cheap brand new.. Much cheaper than a Z32 MAF. However, they do have a Z32 MAF program out, and they push it hard.. versus the Cobra MAF program. Every car that I've ever used a Cobra MAF on.. sucked. It had idle issues, and lacked power. So, there may be some issue with that..

I talked to Clark about redoing some of the programs.. and he agrees. Matter of fact.. in the next few months, he will be using Kojima's turbo SE-R to redo the 50, 72 and test the 96lb program(s) out. I like thier 370cc 4-bar setup though.. bored out stock MAF sensor, with 58psi base pressure on the 370's. 300whp on 370's safely. That program does work realy well.. I realy do hope that they get these programs worked out.. I know for now.. I am letting Scott tune my ECU's for me.. 40whp is a lot..
