need help building a n/a ka24de

[240sx9406]

Trying to fix it up for a grocery getter a dd once in a while take it to the track here in there
im going to need some adivice on a few parts here and there
what do you guys think about this set up? how much horsepower will i make?
Wiseco Pistons and Eagle Rod 89.00mm (Standard Bore) 10.5:1
ARP main studs
ARP 11mm head studs
Cometic Head gasket
New Nissan front end(oil pump, chain, guides, etc..)
Head work: valve job, new exhaust guides?
is this a good set up?

[Irresistible]

N/A KA builds are pointless and expensive.

[wh0aitznic0]

want an n/a rwd setup, get a corolla.

[rb25_s13*CHUKI]

If your gonna do a build like that just build it for boost, Na ka are trashy and not worth the money your gonna put into it. Your gonna fully build that ka and Still get taken out by bolt on b18s and other stock honda engines

Honestly? You've listed nothing but supporting mods as your parts list. Not one of those things you listed will actually make more power over stock. They will handle more power but will not make more. You'd probably be lucky to see a couple hp over stock. Do what everyone else is suggesting, build for boost. Even if you only have the money for the build but not the turbo and tune. If you have a built motor you can simply buy the turbo and tune whenever.

[racepar1]

There is nothing wrong with an N/A KA. I see no reason for you guys to bash.

Honestly though nobody is going to give you any reliable answer on how much power you'll make. First off almost nobody has enough experience to give you a qualified opinion. Most here take the easy way out and slap a turbo on. IMO that's boring. I dis-like turbocharged engines. Second, you have not given enough information. Camshafts are where the power is and without that info even someone qualified can't give you any kind of answer.

I'm planning on building a N/A KA myself. First-off when you get the head ported, DON'T PORT THE INTAKE SIDE. The KADE intake ports are among the best flowing intake ports on ANY head. The problem is the exhaust side. The exhaust ports are dinky and flow like a bendy straw. Simply clean-up the intake ports and port the piss shit out of the exhaust side. Second, you'll need to do some work inside the intake mani. I am planning on extrude-honing mine. Third, if you're going to do this you ought to make sure that it can pass smog. What's the point of a smog legal engine if you've still gotta clean-pipe it? This means that you've gotta keep the compression reasonable and the camshafts mild. This is going to limit the power output, but I think that 200whp is definitely possible. SCCA GT3 SOHC KA's put out significantly more than that and they're restricted.

I've seen a lot of N/A KA builds that are going for 200hp and fall short. IMO this is because the builder always cheaps out somewhere or misses something. To build a N/A engine takes much more skill and knowledge then the average member here posesses. Every single part and piece has to be perfect. It must be thoroughly planned and precisely executed.

[slowvia]

You can certainly build a decent NA KA, but as previously mentioned you'll make gobs more power just by throwing a small turbo on it, and all of the mods you have listed won't really net you any power gains.
A good place to start is with a a full header back exhaust. Delete your emissions junk (unless you live in a place where smog is a concern). That and a cold air intake (don't buy some junk that runs over the radiator, relocate your battery and build an intake that runs over to the battery tray).
After you've finished those simple mods, nothing else will be easy. You'll have to tear into the motor and port your head, bore out the cylinders, bigger cams, higher comp. pistons etc.
And once you're all done inside the motor and out, you'll still probably need to tune it anyway.
My advise? Just do a small turbo build. It's actually not that expensive if you just buy used parts and keep your power goals low. Don't go overboard with a top mount setup with a crazy amount of boost. Keep it simple with a BB S14 turbo on stock boost. I guarantee you'll be pleased with the results.

I'd rather get a b20 honda engine for $300 bucks, Rebuild it throw a Gsr head on it and make 200whp with simple bolt ons on a stock rebuild. Stock intake manifold,stock gsr cams,stock injectors not tuned. Building a Na ka is pointless unless you have gobs and gobs of money to throw around then sure why not.

The moral of the story is if your going to build an all motor car build a honda or a s20ve sentra

Your poor little ka will never make anywhere near 220rwhp all motor.

I would rather not own a honda, thanks anyways...

And how exactly do you know that? what experience do you have to draw from? Stop bashing, you don't know what you're talking about.

[s13chuck]

alex timmons on Houston240sx made 200+ on an NA KA... high compression, definitely good numbers

[Shift n Drift]

people are funny, read the title... he wants opinions on an N/A build. hes not asking if he should go turbo or not.

[rwtf]

if you want a N/a, do high comp pistons, custom headers, ITBs, cams, and a GOOD ass tune.

BUT, by the time you do all that you could boost and make way more power easier.

[Tempo]

all the money spent on building a n/a ka vs. turbo being a better quicker route is whats the problem here.

id personally go with the turbo but that isn't everyone's cup of tea, i think its a cool idea but unless
im balling and got nothing else to do but making a n/a engine super built with supporting mods rather than
just putting on a turbo i wouldn't do it.

[pancakes562]

I totally agree with racepar1. Absolutely nothing wrong with a n/a KA. Those engines are really strong and reliable

This topic has been done a lot before. Few KA's make it past the 200 mark simply because they run out of money or reliability. You do know that if you get your ka to 220whp its probably not gonna be very DD friendly...

Be realistic. If you wish to stay N/A, why not consider a stronger powerplant? VQ, VH, LS, etc etc etc

[nomoremk2]

Turbos aren't the conversation at hand though. N/A motors are fun and clearly that's what the OP wants. Everyone knows its easier to make power with a turbo setup but that wasn't what the dude was asking to hear.

[project-D180]

omg so much hate on n/a builds...anyway i would run je 11.0.1 compression piston which are .20 or wossner 11.5.1 pistons 90.0 over bore. and buy things that will complement your power needs like 3 or 5 angle vavle job,valve spring kit,cams is a big part(pdm sells n/a cams:check them out)4-1 header/4-2-1 ect..tuning is goin to be your biggest thing as with any build,be it turbo or not..they have rom tune,standalone,piggy back(i wouldnt go this route though;not for the ka its jst me).its definitly possible to hit that 200 mark just everyone is to lazy to try n want the easy way out..ooh you could also go the stroker route which would be f'in siick

[project-D180]

xcessive intake mani would be a nice add on or itb's into a plenum would be sick also.thats what the rb26 has n i think 2j also runs itb's in a plenum and you already kno how mean thier accel is,i can picture that on a n/a ka ..whoo

$10,000 is actually quite cheap for a fully built race engine like that. The formula atlantic engines that are dropped into 86's cost double that new...

if you want a N/a, do high comp pistons, custom headers, ITBs, cams, and a GOOD ass tune.

BUT, by the time you do all that you could boost and make way more power easier.

Actually there are plenty of headers to choose from. No need for custom. They've even got 4-1 long tube headers now.

$$$ per HP is whats wrong lol. :coold:

Doing a KA-T setup CORRECTLY isn't cheap either. Most KA-T's are half-assed and end up grenading.

This topic has been done a lot before. Few KA's make it past the 200 mark simply because they run out of money or reliability. You do know that if you get your ka to 220whp its probably not gonna be very DD friendly...

The VQ is step 2, the KA is step 1. I've been planning a VQ swap since 2004. I've even had the engine a couple times.

I plan on building a 200whp KADE that passes the CA smog sniffer test, runs on pump gas, and is completely reliable. Not only that but I'm going to do it on a shoestring budget. All it takes is knowledge and resourcefulness. I know for a FACT that you could make over 300hp out of a KA on race gas with no restrictions or budget. All this naysaying is doing is encouraging me more.

Turbochargers are inherently un-reliable. They create LOTS of heat, which is any engine's worst enemy. They add a LOT of complication to the plumbing, which is just more to fail. The tuning is also very touchy. If your tune is off, you're going to blow it up. They add lots of weight to the front end of the car, which is not good. They are not nearly as responsive as a N/A engine either. A N/A engine with 3/4 the power will keep up with the turbo engine just fine. By the time you hit boost I'll already be on the cam and gone. You'll catch up by the end of the straight, but then it'll start all over again.

The problem that most of you have with a N/A build is that it's too hard. You don't posess the knowledge or resourcefulness to pull it off yourselves so nobody else can.

[e1_griego]

Greaser's n/a ka made what, 210whp?

I'm sure you could do it cheaper that he did, but generally when people talk about building 200whp n/a ka I roll my eyes and tell them to not try.

It's another case of "if you have to ask, it's probably not going to happen."

[racepar1]

It's another case of "if you have to ask, it's probably not going to happen."

I DEFINITELY agree with that statement...

[nismoracingsx]

someone link me to this 300whp ka...i've love to see some video

[shift_down]

You need I/H/E, aggressive cams, port and polish, and a tune. You will only get about 180hp out of it, but you will be hanging with the ls/vtecs. If you throw a t28 turbo on there, you will be at 220hp with VERY LITTLE lag.

[e1_griego]

Prob 300 crank -- either way, look up SCCA GT3 class s13. Rebello built ka's for those cars make great power. Sidedrafts and 13.5:1 compression. We're talking like 24-48 hr motors here, not something you could drive on the street. Also, decidedly not cheap.

Rebello claims about 275hp at the crank. DEFINITELY not an engine to run on the street though...



Keep in mind that the engine internals and the venturis are restricted though. I'm sure he could find another 25hp with no restrictions. And that's out of a single cam!

[e1_griego]

Yup, exactly. I think that's through 34mm restrictors, iirc.

Really fun couple days of street driving, I suspect ;)

[drscooper]

so is he going to go along with this? I would be really interested in seeing if someone actually did this correctly would be neat

OP is not gonna hit 275 or even 225, unless he's got deep pockets and endless curiosity, this will be another thread buried in the zilvia sewers..

Yesssssssee
+2.4

[ReEducation]

Here's some food for thought:

Machined block and head
SOHC pistons in DOHC (11.1:1 CR IIRC)
248/248 cams
Port and polish
Header/ downpipe
High flow cat
2.5" exhaust
Felpro head gasket (Seem to be favored over Cometic on KA's)
Intake
EGT gauge
Iridium plugs
GOOD TUNING (I remember reading something about DIY chip tuning on ka-t.org or you could pay to have it chipped and tuned, but tuning is very important)

Optional:
ARP's (definitely a good idea if you're tearing the motor apart anyway)
Wideband (I never had one in my high comp MX6 but some people want one)
370cc SR injectors
255lph fuel pump ( look at this www.ka-t.org :: View topic - Where to buy "Walbro 255" locally for < $70 (http://www.ka-t.org/forums/viewtopic.php?t=56231))
Aftermarket intake mani and throtle body or ITB's
MAF upgrade

With the SOHC pistons you save money which you could use towards a good tune. Most of the stuff on here is fairly inexpensive except for the machine/head work and intake mani/itb's
