To anyone that may still read this, I sent an email off to Thomas Knight about his superchargers, and this was his reply (sorry for the all caps, its how he sent it to me)
THE COMPLETE KA24DE SC KIT IS NO LONGER IN PRODUCTION, HOWEVER, WE STILL HAVE THE CNC DRAWINGS TO MACHINE THE PARTS FOR THE NISSAN FRONTIER AND XTERRA SUPERCHARGER TO FIT THE KA24DE. THE INSTALLATION KIT SELLS FOR $795 + $25 SHIPPING (TO THE MAIN 48 STATES).
THE $795 KIT INCLUDES THE SC TO MANIFOLD ADAPTER, THROTTLE BODY ADAPTER PLATE, SUPERCHARGER TO THROTTLE BODY ADAPTER PLATE, IDLER PULLEY BRACKET, IDLE AIR AND AIR CONDITIONER IDLE AIR ADAPTER (AIC AND AAC), AND INSTRUCTIONS. YOU NEED TO SUPPLY THE NISSAN FRONTIER/XTERRA EATON SUPERCHARGER, DRIVE BELT ($20 AT AUTO PARTS STORE), IDLER PULLEY ($25 AT AUTO PARTS STORE), GAUGES, AND FUEL CONTROL.
PLEASE NOTE THAT THE ABS BRAKE OPTION REQUIRES EXTENSIVE MODS TO THE BRAKE LINES AND ABS BRACKET IN ORDER FOR THIS KIT TO FIT S13 & S14 ABS MODELS.
WE RECOMMEND YOU ELIMINATE THE SECONDARY BUTTERFLY SHAFT AND WELD THE HOLES SHUT AND PORT THE LOWER MANIFOLD. THIS GIVES AN EXTRA 5 WHEEL HP/TQ. WE ALSO SUGGEST LARGER INJECTORS, LARGER MAF, 65MM TBODY, AND 9PSI. THIS WILL GIVE 225/240 WHEEL HP/TQ. ADDING WATER INJECTION WILL ADD ANOTHER 10-15HP.
THESE FOLLOWING NUMBERS ARE ON STOCK ENGINES (135 HP/150TQ BASELINE ON DYNO) WITH HEADERS & 2.25" EXHAUST @ 7-8 PSI.

Please keep this sort of thing in it's own thread, I split it from the other one (the turbocharged one).
I think the price isn't bad at all... actually it's pretty damn good for what you get.

So could you hit around 250whp with this setup if you ran the supercharger at say.... 10-11 psi.
S-NationS12
Sep 29 2008, 03:49 AM
Sorry about that Arro, and thank you.
I didnt think it was that bad either till I started looking at the prices for Eaton Super Chargers. I think Ebay had them at like 800 or something along those lines. If you could find one of the SC's at a yard for cheap, this is a great way to go...but for a total price of 1600+ and machine work, a turbo might be better.
Still though I would love to see someone supercharged...I'd do it if I thought I could get 350 HP on it

What do you expect for that price? Turbocharging a stock KA24DE costs around that or more. For those not wanting more than the stock longblock can *reliably* handle, this is priced right IMO. That's also quoted TO THE WHEELS, so really that's closer to 280-300 for $800 reliable, lag-free horsepower.
Again, I say it's not a bad deal. I might even consider it now that I think more about it.

its all the time torque, and it would make it go and feel much much faster than a ka-de
not a bad price and setup, i wish the vg33er had a lower profile, id just drop that in my car...
S-NationS12
Sep 30 2008, 01:14 AM
Now someone be honest with me here. What does 300 hp feel like in these cars? Arro does have quite a good point. For semi cheap fairly reliable non lag boost it is a fairly good option. 300 crank HP in S13's seem to drift quite well, and since we really dont have all that many choices for rear tire width, I think 250 HP would do very well going through 2 235 size tires. Also think that the S14's came with a little bit more power, and you can still squeeze more performance out of this option with porting and cams.
Original plan was KA24E-T...looks like I'll be the guinea pig on this. Anyone want to buy a KA-E head and block? haha
Only one question though. In the email, he says that the supercharger wont clear ABS brake lines and Bracket...I know my car isnt ABS, but can anyone see any other problems with the supercharger being mounted on the lower passenger side?

Sep 30 2008, 01:42 AM
i feel that 160 or so is pretty quick for a stock s12... being a v6 car that is....
i feel that doubling it would make for some real fun though, my hp goal is 350 whp on pump gas

i thought the s/c was on the 3.3l engine only?

WHOA! I think I'm sold..sure I may never hit the same horsepower the turbo guys do, but I dont want to really.
I'm with you CarAudio in wanting the 350HP, that was the original goal, but I like being different where I can, so I think this may be the new option for now. Still though, should talk when I pick that stuff up this weekend or something (gimme a ride in the whip, lol)
I'm more turbo guy and I know how to regulate boost on turbos..but what about superchargers? I think i remember something about changing pulleys. How much boost do you think you can run on one of these systems?
I'm at work not doing much so I'll probably research this quite well for the next few hours, lol

Sean supercharged a VG in his S12, I remember because his car had a home depot spec hood vent to plug the hole after it was removed.
I don't know why noone has hooked up an old MR2 supercharger. It would make even a CA20 peppy. I wouldnt even fauck with the ECU just plug it up and enjoy the 6-7 psi.
and by plug it up I mean fab the mounting and rig a pulley. Or use the a/c pulley.

This is what your paying hella money for btw.
Anyone can fab that plate.

, That plate and those studs cost at best $30 from the right place.
Arro
Sep 30 2008, 09:09 PM
Um you're getting a lot more than a plate, you're getting a couple different throttle body adapters. an idler pulley bracket, an IAA and AC adapter... could you make all that? MAYBE with the right tools or the inns with a good local shop, but you'd end up spending a great deal more trial and error with some of the brackets and shit... what you're paying for here is the R&D. You've heard this before in other situations, the real question is are you skilled enough (or funded enough if you have a shop do it) to reproduce that R&D yourself.
And the other question is, how much can you get the superchasrger for?

Been doing research on this all day (I have no life, so sue me, lol)
For one, I'm good at fabricating some things, but I honestly dont trust myself with fabbing up all this. If I had a good friend that knew all this, or maybe if Bart lived close by (Barts the man, give it up, lol) I'd pay him to do it.
As it is this kit has been installed and ran on 240's before.
As far as the supercharger, one website quoted 800 new, 450 remanufactured...I lost the website and still searching for it desperatly.
Superchargerpros.com quotes 685 + 200 core...still curious bout this though because if I wanted a supercharger, I wouldnt normally have a core.
Arro
Sep 30 2008, 10:54 PM
I'd pay 450 for a reman w/ a warranty from an experienced vendor. That's still around $1300 for a correctly-fitted supercharger setup. You'd still need and AFC and some injectors, but that's not a big deal.
S-NationS12
Sep 30 2008, 11:16 PM
Yea, I'm really starting to come around on this idea. I keep thinking that "its ONLY 240hp they made"...
But our cars can be VERY decent with that power. And that was basically a stock motor, you can still do numerous things to bring that power up a bit or make the engine more lively (I.E. light flywheel and pulleys, head porting, 2.5 exhaust instead of 2.25, cams)

I have only seen this kit on one car which was on Nico once.
There's a section on ka-t.org for the SC'ed guys and they run M60 or M62's not sure but there's a guy that had a dyno sheet of his setup if you want to look, go check it out at ka-t.org/forums. =)
I put a lot of thought into this a while back when I was going to buy a S13 but I decided TURBO is the way I want to go.
rage
Oct 1 2008, 05:45 AM
i also wouldnt trust an AFC when running an n/a motor on boost, any kind of boost that is, unless youre just drag racing a little bit.
the fuel/engine management will be where the money will need to be spent, if you want your engine to last. the thing about AFC's is that they cant control timing, and timing is critical when boosting an n/a engine. its the main reason why peoples engines blow
IMO, its about the same money for a turbo setup sans engine/fuel management, if youre frugal and look around
Arro
Oct 1 2008, 06:00 AM
Don't be so defeated by the fuel issue and the AFC concerns... just run a rising rate FPR and a Walboro 255lph pump and I'm sure that will handle things.
That's how the Honda engines dealt with the JR roots blowers.
My only question is how close to 100% duty cycle you'd end up on the KA24DE's 270cc injectors. If they max out, you could run S13/S14 SR20DET injectors (370cc), 95-96 Z32 Turbo injectors (370cc), or S15 SR20DET injectors (480cc). All those injectors are the same kind of side feed as the KA24DE injectors, and you could use an AFC to correct it back to stock flow, then the RRFPR to pump up the fuel as the boost rises.
It could work.
rage
Oct 1 2008, 05:04 PM
the stock 270cc KA injectors will get you to 190bhp not whp and thats at 100% duty cycle mind you. the 370cc's will get you to 260bhp and 480cc's 330bhp.
you can also use FD injectors(550cc primary, 850cc secondary) and STi injectors(565cc's) just be sure to grab the injector clips
Arro
Oct 1 2008, 05:38 PM
Or 93-02 Supra turbo injectors.
S-NationS12
Oct 1 2008, 06:11 PM
I'd build the motor to be reliable (I know its not really needed, but I wouldnt trust a 100k engine and tossing boost at it and expecting it to run as hard as I'll run it)
Can anyone check on something for me though? I would run Walbro no doubt, but S13 guys lately are picking up Q45 fuel pumps, I dont remember how much more they push, but I remember people throwing them in with RB swaps so...
As far as injectors, I'm sure you wouldnt need more then 480cc on the supercharged KA...even fully built
Arro
Oct 1 2008, 09:20 PM
You don't need anything more than a Walboro 255lhp pump, trust me... Supras and DSM's running 10's and 11's in the 1/4 use them with 20+psi. I think you'll be way under that

Besides, the Walboro is cheap.
SCPOW
Oct 2 2008, 03:48 AM
Anything above 550CC's and the S-AFC won't be able to compensate your fuel issues for you, keep that in mind.
If you do decide to go this way, keep us updated. =)
Arro
Oct 3 2008, 09:52 AM
That's not true, DSM's consider 550cc's an introductory upgrade, and 460's w/ Super AFC's are routine. It might mean he'll need a different *airflow meter* at that point but that's no big deal, if you go with one that the AFC already knows about, like a Z31.

Oct 3 2008, 04:02 PM

I will be going with a bit of a different style color choice, lol

Oct 3 2008, 06:10 PM
There are pros and cons to sc vs turbos. With sc, you have power all the time. Which does hell for gas mileage if you are just putting around town. Turbos tend to be better IMO for regular street driving. You can also pretty much adjust your boost on the fly. With superchargers this requires changing a pulley. If the build is for a track car only, I would probably go with the sc setup. But when you are just driving around town, the sc will steal your gas. Well, more so than a turbo.
I'm not saying either one is bad, its just that you need to consider what you will be doing with the car once it is built.
Arro
Oct 3 2008, 06:20 PM
That's true, you can lazy-drive a turbo and keep it out of boost.

EBAY - 240sx SuperchargerI DO have the money for this, I DO plan on buying this but let it be known that if anyone else will want the machine work diagrams and anything else, I will let them go for little to nothing..
PLEASE dont try to undercut me on this and pick up the kit yourself, as I said IF I do get this kit more then likely we can have them made for less then I will end up paying...
Since my first build I want to go NA, and the only local KA S12 guy around here is Arro...I wonder if he would mind being the guinea pig on this (no offense)...I will throw this on a KA at some point and throw THAT into my car, but it may be a while. I'd rather someone drive it and enjoy it first, lol

Basically..Yea
I'll pay for everything as long as there is the understanding that when my engine is ready, it goes on mine...before we throw it on we'll have a machine shop duplicate at least 1 of all the components incase anyone else wants to do the same..I think it may be a good idea for Henry too.
After the kit, we have to buy a supercharger...then its install and probably small stuff.

S-NationS12
Oct 23 2008, 08:48 PM
Depends...turbo depends on boost..if your not boosting your technically NA - Supercharger is ALWAYS boosting and uses the engines own power to boost..
HOWEVER, from what I've heard, its not that bad at all. 350z's with like Vortechs get -1 or -2 tops on gas mileage from what I remember. Best way to find out would be to find a review on a supercharged Xterra or Frontier since it is the same supercharger. I'll look that up in a little bit.
Arro
Oct 23 2008, 09:04 PM
Well that's fine, I'm not gonna be doing anything with it turbowise until the suspension, wheels, brakes, and exterior crap is finished, so you can have free reign on the engine. If I like what you do, I'll just do the same thing. But I'm pretty sure after that I'd rather go turbo.
S-NationS12
Oct 23 2008, 09:23 PM
Same here, but then at least I know I'll have tried everything, you know. IF the supercharger has the power for drifting that I want, I wont change - I may try some other method of supercharging though...who knows what the hell we can come up with, lol
Or hell, even trying to fit an intercooler to the supercharger, a cooler charge = more condensed air = more air in the cylinders during combustion = more power.
ITB supercharger maybe?
There are a ton of ideas running through my head, but finding one that may work, have gains, and be affordable is the hard part
Arro
Oct 23 2008, 09:26 PM
You can rule out ITB's then, they aren't affordable, because they'll pretty much require a stand-alone EMS.
I just started up my car today, I think I need a new water pump, it's got a very tiny bit of clatter coming from there. But otherwise my engine is sound. Whenever you're ready, PM me and we'll plan things out.

Oct 23 2008, 09:36 PM
sure, let me win this ebay bid first, lol
and kinda bad news...the Xterra's V6 is rated 16.7 MPG, and the V6 SC is rated 13.5 MPG back in 02.
and I'm a couple weeks away from buying megasquirt for my car anyway - and if you have ITB's connected to a Plenum, all the air still needs to go through a air intake which is still measured by a MAF sensor, so you MAY be able to get away with no Standalone...though it would be a smart idea.
Arro

If I were supercharging a KA24E - ITB's would be a smart idea, Ive heard cylinder 4 tends to not get as much oxygen as the rest of the pistons and blows when boosting...
But your right, ITB supercharging is kind of a dumb idea...

Thats what everyone keeps saying, but for some reason everyone still wants a turbo. I got a place to get cheap fender flares so eventually I'll have 15x8's out back - but I dont think 220hp and what-ever-amount-of-torque from the supercharger will hold traction with the 245 size tires. If the KA NA is fine, why does everyone hate on the supercharger? Why isnt everyone happy with bigger cams, and a few bolt ons? Why is everyone insisting on a Turbo and 300+ hp? I'm not flaming, but I'm somewhat confused now, lol
Guess thats kind of why I wanted a ride...to see peoples point of view on this
Arro
Oct 23 2008, 10:17 PM
If more people understood that powertrain isn't everything when it comes to speed, they'd spend more time on other components.
But the reason why I want to turbocharge it is because as nice as the KA24DE is, it's not 250hp.
