Worried about torque

[Neejay]

Ive been debating on what to do engine-wise, and I thought I was sure about ca18.

The only thing Im kinda worried about is torque. I know its a 1.8 vs. 2.4 (sohc, what I have currently), and that it has more torque than a ka24e, but can you actually feel the 1.8 vs. 2.4? I daily drive, so torque is what I want.

Im not going rb or ka-t, just dont have the resources/time.

[themadscientist]

torque is fine, it just comes in a little higher on the tach.

But what about daily driving? I wont be redlining or getting to 4.5-6k from just daily driving

[themadscientist]

I think you may be freking out a little man, it's not a lawnmower engine. The ex's 180 kicks out the *** if you drive it like that, you will have to learn not to wind it out

[btustison]

The torque feels better than my KA did. I am running a T28 on an otherwise stock engine so it take a little more time to spool but it is still fine for a daily driver, in fact the mid range feels really good and the torque curve looks pretty good on the dyno.~my .02~

You'll just have to learn to keep it a LITTLE higher in the RPM's that's all. The torque on the CA is just fine for daily driving in stock form.

Now if you do like I have an lighten the entire reciprocating mass, it's a little harder, but still definatly driveable.

Thats gonna be hard...because I need to practice driving a manual...lol...

I hope by the time I get a ca, they wont be too old and hard to find parts for. Im itchin to get one, I want one so bad, just cant afford it right now.

Thanks guys, guess I will still stick with a ca.

[biosehnsucht]

torque is fine as long as you have the variable intake gizmos workin'

once i was running on 4 cyl again I could finally power over.. 3 cyl don't cut it tho

[sdtouge]

3 cylinders? **** i was running on 2 except when WOT lol.

[slownslurious]

my ka24E was a torque machine and sucked anywhere above 3kmy rebuilt ka24DE with upgraded mafs and injectors and removed emissions was a ****ing powerhouse, I prolly coulda pulled stumps out with that one. Till it blew up. The ca just keeps pulling till the turbo gets tired, and you have to launch at like 3k to get a good launch, and I shift at 7000 when I'm spanking it. The ka I would launch around 2200 rpm's at most, and shift at like 5300 rpm or so.

So you're basically saying that they each have their own torque specs, or that the ca18 was overall better?

[slownslurious]

I think the CA was faster than the DE but I'm not sure... my DE was far from stock and very fast...and it blew up rather quickly... the DE defintely wins the torque war, I mean **** with open diff I was getting wheel spin shifting into third gear...the CA I suspect is probably faster, the power band with the turbo is so much wider... the DE would probably beat it off the line but once you started switching gears I'm sure the CA would take over... and the CA defintely has a higher top speed and better highway passing power, though it helps if you bump it down a gear.

I kinda relate it to driving a sport bike. Don't expect a lot of low end grunt. But once it gets wound up, it just pulls and pulls till the turbo runs out of air, or you hit redline. It's sooo much more fun to drive. Just don't expect to get rolling from a stop w/o revving the motor a little. I remember that I used to be able to just barely slip the clutch in the KA and then take off w/o touching the throttle. NOT gonna happen in the CA.

[tyrannix]

its kinda funny you mention that, because i *could* just let out the clutch, no throttle at idle and then start accelerating (not for a launch of course, but out of a parking lot or something) just like a bike, without stalling ... not sure exactly what everything was set at at the time tho, but weel see if its still that way when i get my engine in .. (still waiting on oil pump)

Thats what I dont really like....like I said, I'll be daily driving only, so I WANT low end....but then again I guess I still dont need to take off fast if Im not racing...

Im running GT28R on a bone stock CA motor, torque comes in around 3500 and pull strong. You'll be very happy with the CA, like I am.

[r34 gtr]

ive got a gt28r on mine too and the torque is plenty for daily driving. when i had my car dynoed (waaay back when it was running really badly and was stock as balls) i made 151whp and 164ft.lbs of torque at 3800rpm. not a bad number if you ask me and it *was* plenty for driving around town.

with 10psi on the gt28 and proper fuelling ive got gobs of torque. way more so than the t04r powered fc i rode in the other day, if youll allow me to brag....

by the way, my car looks exactly like yours neejay. if youre ever down near auburn let me know and ill be happy to show it to you (im not too sure where in georgia stockbridge is...)

[JDMSIL80]

^ Tim: What was the peak number you hit from the dyno with GT28R? What other mods have you done after?

I really like the response that this turbine gives and the way it pulls all the way to redline. My next mods would be FMIC, manifold, dump, and downpipe. Hopefully I can see some decent gains out of them.

[slownslurious]

its not about the peak torque, its about the powerband... the ka is way easier to start off up hill and stuff...

[Neejay]

Yeah, like I said, daily driving only.

Now, would the ka SOHC be that much different than the ka DOHC compared to the CA?

[N053B133D]

I am by no means trying to be rude... But you keep saying "daily driving only" why not just get a daily driver? or keep your stock engine? you don't seem very interested in high performance, so why mess with it? The stock KA motor is fine for daily driving if that's all you plan to do with it.

I was just going to say this? What kind of power DO you have in mind or hope for? I mean, if this is strickly going to be a daily driver, why not stick with the KA? It's a great motor in that aspect and has plenty of it's own merits. For a daily driver, I'd LOVE to have an S14 Zenki w/ a lightly modded NA KA24DE.

Good point. My point is that I dont need a HIGH performance engine (i.e. different setups for autox, for drag, etc.)

It just like people buying high performance cars and they hardly see the road. Granted, I might get into autox or something once I have more horsepower/manual.

Also, you know how some people would be like "rebuild it and get forged pistons, greddy manifold, etc. etc." thats why I push daily driving..lol Granted, I know that would be a badass engine if I did rebuild it, but its not necessary.

Well...its like this:

Im not too sure of the condition of my sohc. And if I gonna swap, I want to go beyond just a dohc (hence the reason Im not going sr/rb). So where as I COULD just get a s14 DOHC, that would be boring to me

[slownslurious]

I'm pretty sure a completely stock CA with intake and exhaust versus a ka24DE with mild upgradeage (header, intake, exhaust, ecu retune, maybe some cams) would be nearly even (I'd imagine the ka24DE would probably win), and that stuff would probably cost less, be more reliable, etc...BUT if you aren't going to be satisfied with that then the CA is turbo and you just start adding boltons and cranking the boost and you have more power. with the KA you are gonna hit a wall.

[themadscientist]

My CA18DE would have given a KA a poke in the nose and I didn't even have a turbo, just header, muffler intake and fuel. The CA18DET would kick a KADE square in the jubblies.

[slownslurious]

yeah that 10 hp is really gonna smother it.... *rolls eyes*

[WeldingHank]

intake, exhaust, and boost controller will make 180WHP.

[WeldingHank]

check out that torque curve, its a hella fun car to drive around on city streets. this was just intake, exhaust, boost controller, SAFC and FMIC. the SAFC and FMIC would be optional. you could probably make this on a SMIC without an SAFC.

[Neejay]

Nice, nice.
