All motor 240 ideas.

[sillyvia13]

I would say a na ka...
when you push HARD for power...you usally lose alot of life! in motor.
IMO and exp.

a hardcore ka would be fun....like a rip around a track in the sohc race cars...110 octane...fun funfun

[sav180]

i think sooon as a couple of people build a na ka set-up that puts out over 200hp with out goin too over board then all the nay sayers will fall back..you guys are talkin the same way as when people 1st starting to turbo the ka's,sayin all this negative shhht and now they got ka-t puttin out over 700 hp...so let's cut da sh*@ and work together to make this happen...

[wannabe_drifter]

About ITBs. gsx-r 1000, they are 42 mm at the smallest point.

The hayabusas 1300 are supposed to be 46 mm.

Who says our stock runners are big enough to support a high HP N/A set up in the first place? I would think somewhere around 50mm is more what you would want personally. I'm going to check the SCCA rule book that I have at home to see what the KA's throttlebodies are restricted to.

Why wouldn't a moderately built and well tuned KA be reliable? KA's are known to be pretty bulletproof!

Well I meant enough as far as comparing them to the stock Intake runners which I agree, for our 2389cc's 42 and even 46 are kind of small. But I'm sure if you bore the ITB's to 50mm and the Intake Runners because those things are beefy, I have an Excel program that does ITB's calculation for an engine I just have to find it.

[Matej]

What are the most popular ITB's among Corolla owners to run on 4AG's, are the GSXR the commonly used ones?
Is there a good website where I can read up on how ITB's work and learn more about them?

ls1 swap. then drive really really fast.

Wow! Spectacular insight! {sarcasm} Seriously what does this have to do with an all motor KA?

it has nothing to do with it, an ls1 is better than all motor ka

[KA240SX808]

Yeah, NO!

As for MateJ:

Here's some Specs on some Cycle ITB's:

There is always someone that has to come in a NA KA thread and say the Ls1 is better, for what reason, it has more power? Too bad it has 4 more cylinders to make that power. I myself would rather spend less than half the money towards a 200whp na ka setup while still keeping the stock motor.

[Signum Temporis]

well... as the thread is called "all motor 240 ideas." i posted a reply "ls1 swap. then drive really really fast." then someone wants to get on my case about it and give me -13 rep.

Dude THIS thread is about all motor KA's! An LS1 has nothing at all to do with this thread. We all know that the LS1 is an all around better motor, shit I want one myself! But that's not the point here. A well built, ITB, all motor KA is badass and anyone who says different is a moron!

[haz-e]

Sure would be swell if the KA's were square motors. You can purchase the higher revving valvetrain stuff from Rebello. Last time I had checked their site I could sworn they had complete engines listed. I thought Rebello also slightly destroked the KA? DeviousKA on here has done alot of work to the NA SOHC KA, suprised he hasn't chimed in; His car ran mid/low 14's I think. Devious was looking into destroking but no sure if he got there, or found it feasible v cost.

[racepar1]

Meh, I want the BC 2.65 litre stroker kit! I want TORQUE! GOBS of brute force torque! High revs are cool and all, but just not what I want from my KA.

[KA240SX808]

Plus the BC Crank is Fully-CW so I'm sure you could still take it upto 7k, thast enough for me.

[240cracker]

id say VQ swap..

UGH! Not AGAIN! THIS thread is about all motor KA's what does a VQ swap have to do with that at all? Please keep this crap outta here.

The title of the thread was misleading. I originally thought he wanted any NA motor in a 240, but if you actually read the first post you find out that he really wants to build a KA-E NA motor.

Reading comprehension? What's that?

[MikeisNissan]

yeah if everyone played by the rules here I would like this thread.

[Tulok]

the destroking kit sounds like the way to got for ultimate power.
when you destroke a motor the average piston speed goes down, allowing you to safely rev higher.
That, combined with a super aggressive cam, oversized valves, 14-15:1 pistons and individual throttle bodies would definitely give the flow and revs needed to make all that power.
not to mention underdrive pulleys, race tuned headers, electric fans etc.
any flaws i am missing here?

EDIT: I did a quick calculation and the numbers I came up with make me more suspicious.

2400cc x 7500rpm is 18million cc/min
1000cc x 15,000rpm is only 15million cc/min

According to those numbers the bore size of the gsxr throttlebodie is almost certainly not quite sufficient to support 2.4 litres of displacement. I don't know the redline of the gsxr off of the top of my head though so if it's higher than 15,000 rpm's then the numbers will get closer. Basically these numbers are just to compare approximately the maximim airflow that the throttlebodies were designed for to the maximum airflow needed for the extra displacement. These are just a tool to compare, not actual real numbers.

what about itbs off of a 1300cc?
or boring out the itbs?

My neon is the drag/corner car. on street tires it will hit some 12's and look bone stock... all the way down to the exhuast. the 240 is about the style and i wouldn't mind playing around with drifting. nothing serious cause nothing like that is around wichita, ks.

My setup for now will hopefully be like this:
4.6 gears if i can find them
1.5 or 2 way diff
cam
intake
header back exhaust and a computer tune.

If i feel like that wont cut it i will go with a factory rb20 swap and be good.

To really go mid 13s in an S13 without extensive weight reduction, you're going to need somewhere in the 215-230 rwhp range. I don't think a streetable NA KA is going to get you there.

You might crack off a high 13 second pass in a 2500 lb car when you spend a lot of time chasing a little power here and there. In a car with full interior and AC, I'd say you'd be good hitting low 14s.

[Tulok]

I bet you could find some that are bigger than the busas, and retrofit them to the KA.
At what point would an NA need upgraded injectors?

same weight
same power
not boosted
half the cost
hmmm
ls1 ftmfw!!!!!!!




okokok fine!
so to make 250+whp on a ka u need itbs, tuning, stroker, big cams, custom headers, headwork up the wazooo, oh man you better have deep pockets!!! no thanks there are much better/simpler ways to be as fast.

Your info is WRONG! The LS1 has:

More power

The ka is not boosted either.

A well done LS1 swap will cost just as much as building a badass all motor KA, more if you cannot do your own fabrication as the bolt-in kits generally suck.

You felt the need to bump this thread with wrong info that has nothing to do with this thread at all, you FAIL! If you think a proper LS1 swap is ANY simpler or cheaper than a well done all motor KA then you need to pull your head out of your ass. You don't want an all motor KA, cool.......good for you! But if you are not interested in an all motor KA then what the hell are you doing posting in this thread?

[300hp owen]

wow you got your panties all in a bunch over what, wow dude chill the eFF out, thanks for the neg. rep, thats so cool. you rock.

many people mentioned the GT2/3 cars running 300HP all motor KAs and THAT IS WHAT I WAS REFERRING TO you fucking douchebag.

an all motor KA that is comparable in power to an LS1 will cost MORE than the LS1, imho.

lol you are messed up in the head man, or you think the LS1 swaps are hard as hell and uber expensive... Ive done LS1 swaps so I have a bit of knowledge on the subject, but you, are you being a bitter dreamer or just a douche today. posts like yours with hysterical negativity and no room for humor are just another reason the intArweb sucks.

lol. you fail.
