What Is A Easy Way To Gain Torque In A Ka24E Sohc Engine???

[Shift n Drift]

i wouldnt really bother rebuilding a motor unless you dont have good compression or if your burning oil, but thats me, do all your upgrades you have in mind and check compression atleast once a month or something like that, ill see if i can find more on the jwt cam and tune, but if i cant, im sure ill see that awesomely sounding single slammer again and ill ask him for you.

[LadyJdm]

hehe thanx =)

but yeah i wanna rebuild the WHOLE THING, everything will be done, and i'm going to do alot of research with this motor. but i know if i build the single cam it would seem to other people wasting money and time, but i REALLY LOVE my single cam, and i think it can be the little monster people look twice on<3

so if someone tells me again im wasting time on this single cam, this isnt the forum u should be posting on.

i know alot of people here love single cams, so i just wanted to start alittle something with single cams and see really how far they can go, then someone telling me its weak.

At this point of your ignition timing, you will have the maximum low end torque capable of being produced by your cute little SOHC KA in it's "as is" internal condition.

Awesome "tune up" the Hondas love it too.

That is dumb. A good way to damage your motor in the long run.

To be honest, why is this thread still alive? If this wasn't a girl and someone a few of you know, they would have been flamed into oblivion and told to search.

Do what you want, its your car, its your build, make it unique and your own. I've stayed single cam since 06 regardless of what everyone's told me. Its not a waste of money.

You answered your own question.

[keiglo]

just keep doing what you're doing. Like charlie said, its your car. Build it up however you want to, and keep rocking the single slammer! i know i will!

[stinky_180]

rebuilding it would be your best bet. and to the above comment about advancing/retarding the timing is the dumb and dated. dont advance/retard timing via distributor, run base timing and advance or retard via the ecu rom... probably an advance topic for you though.

[bones321]

quick question guys i just installed a cam in my car and wanted to know if you need to shim anything, like the vavles and such

[SoSideways]

...........

Most KA-Es are seen as "throw away motors" by all the fanbois and toolbags, so it shouldn't be more than like $50 to $100 to pick up a spare block to build up for turbo while you keep the motor in the car in NA form.

[LadyJdm]

oh well this forum hasnt been closed its a good place to ask random questions, because random questions can lead up to some smart ideas =)

but yeah timing is way off on my car also, because i have a 89 motor but i have a 93 pulley lol but im gonna install the 89 pulley i just bought and see how it goes.

[davirene]

Heres a lil Motivation for u....build your suspension first....then finish off with your motor....

[CrazyRob]

i read the first page. this thread is stupid. figure out your end goal. repost your thread with a more logical and well thought out goal. get on the track to figure your car out. end fucking thread. everyone just stfu.

[GripTerror]

nistune there.. easily 20-25whp with a tune on boltons.

[LadyJdm]

davirene

damn clean motor! i hope ill end up being turbo by this year, if not atleast all motor will be fine, =)
but well its hard to pick where to start and end honestly =/ i mean everything changes and theres always different and better ideas as u go on. and i think even 2-10 years from now ill still probally be working on my single cam lol<3

but i already have suspension and etc on my car, my car has all the stuts,sway,tow, etc bars u can think of, but all i need now is to build my motor ^__^

but im going to try out the bbp headers and see whats up and info on u guys on them<3

Nice motivation indeed. Although you may considering moving that maf further out of the turbo with a bend preferably. Better IC setup would compliment that Excessive IM. Check out my KA24E-T build here in Zilvia now sold to Charlie321.

[Shift n Drift]

here is the jwt cam i was talkin bout Jim Wolf S1 Billet Camshaft KA24e 89-90

hope it helps somebody

[LadyJdm]

ooo thanx! i was looking for some camshafts also, thanx!!! =)

any little bit helps guys, its hard to find single cam performance parts =p

[LadyJdm]

oo i got a question? if u buy pistons what is a good compression ratio for pistons with either building a motor or turbo???

i dont know alot about pistons >_<

[SoSideways]

High compression for all motor build, low compression for turbo build.

Make sure you talk to the engine builders too while you're building these engines, because if the compression is too high for the all motor build, then you won't be able to run pump gas on that motor, which could pose a problem.

is that the excessive intake plenum? if so, how do you like? what emissions equipment are you using? ease of install?

what are you running for engine management?

or you can run the flat top pistons that came out of the VERY EARLY single cams, 9.1:1 compression ratio. it'll be just as reliable as stock with that little extra juice.

[Hashiriya415]

You can run high comp pistons, when you go turbo you will have to use race gas, but it doesn't always mean like everyone says you have to run low comp pistons for turbo, many race cars have around 11:1. But if you are trying to make the most power you can then you want to lower the compression down

[Antihero983]

Remove KA-E, Install LS1, Enjoy Torque and reliability.

[LadyJdm]

hmm wow that was different the way i was thinking bout pistons lol

so lower comp. rate for turbo for the most power?

and higher comp. rate for all motor? got'cha!

and nah i cant be able to do the higher comp. with all motor.. lol my car is a daily driver. i cant spend 10$ on a gallon everyday lolz =p

and do they still sell the higher comp. rate pistons for the earlier single cams, 9.1:1 compression ratio?
i cant find any T__T

[keiglo]

Lower comp rate for turbo for most power is basically right, but i just want to clear it up a bit. The reason you need low comp pistons if you're going turbo is because its forcing more air into each cylinder, so there is more pressure being compressed, which automatically raises compression. So running low comp pistons means that its going to compensate for an increase of compression from having the turbo. If you run high comp pistons on turbo, then you will throw a rod or put holes in pistons because there will be too much pressure/air that is trying to be compressed

The exact opposite is true when you want to run an all motor setup. High compression is wanted because you wont be forcing the air in. This will give a faster and cleaner burn, which will make more power.

As for the pistons, im not to sure. I know that if bore your cylinders, that raises compression. But only VERY slightly. if you bore all cylinders .040", it'll add maybe 0.2 to your compression. With that you'll also increase displacement, but that is also very little, around 2.5L instead of 2.4L. Every little bit counts though if you're going all motor build.

[keiglo]

Actually, boring cylinders does increase compression. Compression ratio is the ratio of the cylinder volume with the piston at BDC divided by the cylinder volume with the piston at TDC. Boring a cylinder increases volume. The volume increases more with the piston at BDC as opposed to being at TDC. When the piston is at deck height, then the volume with the piston at the top of the bore does not increase, but when the piston is at BDC, the volume is larger. This makes compression ratio higher.

again. not by very much.

[sparkyS13]

very good discussion

Alright.

I retract my previous statement and post.

You are correct indeed.

However, just like you said, compression gained through boring a cylinder bigger will be minuscule, especially on a relatively low displacement 4 cylinder.

Even on something like SBCs, the compression increased through boring a cylinder is pretty small, compared to using heads with smaller combustion chambers instead, like putting the 5.3L truck motors on LS1 motors or something.

[keiglo]

^

exactly, and it costs money to bore cylinders, so unless you have access to the machines to do the work yourself (or just have enough money to spend), the compression wont raise a great amount, so most people dont do this. Its all about how much you want to do, and if you want that little bit more.

[LadyJdm]

damn that makes much more scene about pistons then, thanx for clearing it up for me keiglo ^__^ but hmm i might bore all cylinders and get that extra power, i mean at least ill be alittle ahead of the game lol

Extra power by boring 1mm? I would like to really see your dyno #s after.
Don't forget to calculate the extra weight of the piston, and the extra friction of the rings. And boring and honing is expensive?? I charge $60 for 4 cylinder $80 for 6 and $100 for 8.
