Nice! What is the bore size of the gsxr throttlebodies though? I'm not convinced that it is big enough to really support 2.4 litres of displacement. After all they were designed for 1000cc motors, that's less than 1/2 the displacement.

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?

Tulok · 05-17-2008, 10:02 PM

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?

imperial562 · 04-08-2008, 11:51 PM

this is sad... you guys expect to low from a KA motor.
If any of u guys know abot these Honda Motors, then you know how much further we can take a NA KA.

Yeah but look at the Honda's VE compared to ours, there in the very High 80's low 90's, were probably in the low 70's. I mean they can run 11:1 C/R and still be on pump gas before pinging, w/ 10.5:1 KA's have to actually watch them selves before they start pinging. So I dont think our motors should be compared to an Honda one atleast. I might be missing the point here but thats what I'm seeing. D-Series SOHC FTW

bo2o · 04-09-2008, 12:14 AM

wouldnt you want a shorter gear? so you can smash thru your gears reallie quick

with a NA build i would start about by sending the block and head to machien shop.

get 90mm bore pistons h beam rods or cyro treat your stock
90 mm with 11 or 12 to 1. then square port with port, and polish and get new valve train new head studs nismo cam, and get a 5 angle valve job.
custom intake mani or port match your stock and put q45 tb.
jack knife your crank new crank pulley i think ati one would b good. hotshot headers 555cc injectors kould be found on rx7 not shure what they have exactly but there pretty high fpr and walbro.
ecu tuning. or emanage. wideband o2
that should be what your looking for should be good up to 200 whp

ive heard on a fresh block with juss mods to the head can get your 180hp.

Yes that's why we Opt for the Nismo 4.364, Xterra 4.6 & 4.9

KA240SX808 · 04-09-2008, 01:14 AM

I believe the GSXR-1000 02'+ ITB Dia. is ~42.5mm IIRC, I'm sure you can get someone to bore them out to 44mm.

I did some research and it seems the 98-99 GSX-R750 ITB's would be more Ideal w/ the Butterfly dia at 46mm

Our intake runners are ~44mm: So I think the 98-99 750 ITBs are more then enough

Matej · 04-09-2008, 02:40 AM

How reliable are built n/a motors?
If we were to compare a crazy built KA vs. a mild KA-T, which one would be most likely to blow first if they're both driven hard?

sillyvia13 · 04-09-2008, 02:48 AM

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 · 04-09-2008, 07:25 AM

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 · 04-09-2008, 10:17 AM

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

The hayabusas 1300 are supposed to be 46 mm.

Matej · 04-10-2008, 11:50 PM

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?

Signum Temporis · 04-11-2008, 12:15 AM

ls1 swap. then drive really really fast.

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.

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?

Ive done LS1 swaps so I have a bit of knowledge on the subject

You are both right. V8 swaps can be cheap, but it's not going to be quality. I've seen just about every LS1 mount kit on the market and they're all crap.

owen, peep my posts in the V8 thread.

The only proper way to do any motor swap is to shove the motor as far back as possible. My firewall was moved back at least 6" and the motor shoved as far back as possible for better weight distribution.

My carb sits much lower than the intake plenum on comparable LSx mount kits due to the way their mounts sit on the subframe. Mine sit extremely low and requires no mod to the subframe.

The conclusion is that both people are right. Move on.

This thread is about NA KA-E single cam. If you want to argue other motors, please start your own thread or post in the thousands of other threads arguing the same thing.

KA240SX808 · 04-11-2008, 02:29 AM

Yeah, NO!

As for MateJ:

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

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 · 04-13-2008, 10:26 PM

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 · 04-13-2008, 11:11 PM

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 · 04-14-2008, 12:10 AM

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