Thread: S14 with SR20 or KA24

^^^yikes rough





ok i do agree that the ka will make a good drift engine cause of the torque

i dont agree that sr's are always hitting limiter to keep the wheels spinning, they hit limiter because they have enough power/torque to freely smash limiter when mashing the throttle. All my mates drift cars with 2jz's, rb26's etc all do the same. Put a 2jz into a s chassis and drift it...it will be hard to stay off limiter

ok there are still plenty of sr20's running in japan, kiwiland, Europe, here and even a few in formula d (there is always going to be less in formula d sue to the fact the engine wasn't released in your country, it's a wonder you have any at all)

also in regards to you 350z comment..you mean like chris forsbergs 350z?

also the 350z engine aint the best engine to use for a ka argument as they run overbore, where their bore is bigger than there stroke and rev beautifully!

Even though i was cranky earlier cause i was tired, and played devils advocate because the word "superior" was used, but i think i have gotten that point across, i dont think the ka24 is a bad engine and can produce some nice torque and power. Personally i am not a fan of huge power without any torque or huge torque without any power, but thats just me. The ka doest fit into either of these categories though

Also the reason they tough is because "i think" the bottom end in them was used in a turbo diesel truck in japan. I could be wrong on this though...wouldn't be the first and wont be the last



ok dude do mods in this order they are seriously soo cheap

1st alloy craddle bushes, or pineapples

2nd ohh i cant choose here, either coilovers heavier spring rates at the front for the rb and run some negative camber at the front, not a stupid amount but some. Or swaybars, they make a big improvement too.

3 castor rods...pump some castor

and if you dont already have them...i assume you do, some 17 inch rims

do all of these and the car will feel like a different car

I get everybodies point but the bottom line is a t-25 Ka24 is better than a stock sr20 ive seen both in action im not impressed with sr20,s in 240,s on street trim sorry, with 6,s and 8,s thats different story. And if you mod both the same with the exception of a ($10,000 stroker kit for the sr20) or whatever they cost the ka24 will always be faster,and with that price you better off saving yourself the money and time and do a LS?, these motors fit and look real good in S14,s damn it.

From your own link:

torque
   /tɔrk/ Show Spelled Pronunciation [tawrk] Show IPA Pronunciation ,
noun, verb, torqued, torqu⋅ing.
–noun
1. Mechanics. something that produces or tends to produce torsion or rotation; the moment of a force or system of forces tending to cause rotation.

(emphasis mine)


By the definition; torque can be applied, and yet no movement take place. Furthermore, when pure torque is applied, no acceleration can take place.

Call me an idiot [when I'm in the right] again, and I'll stop treating you with any amount of respect. This is the last straw.

I invite anyone who thinks I should be banned (on any forum I'm a member of) to start a poll. If it comes out in favor of my banning, I'll gladly leave where I'm not wanted.

When we compare these motors, do we compare them stock? Do we compare them modified with a certain budget? Do we compare them modified with a limitless budget?

At the end of the day we have the KA with a cast iron block, longer stroke, and lower flowing head. We have the SR with an aluminum block, shorter stroke, and higher flowing head. Everything else is easily changed about the motors. It's up to the builder to decide what platform they want to start with.

And we're brought back to the point that was (rightly) made early on in this thread. It's up to you to decide. No one else can make the decision for you. We can help by teaching you about each motor, but please think twice about opening Pandora's box next time and try to refrain from asking the "which engine is better in ____ chassis?" question. Instead, ask what the differences in the motors are, and how hard the swap is.

HA HA HA!!!!!!!!! BENNER FENNER IS RIGHT! Sorry I couldn't resist this thread, but I haven't checked on it in a few days. HP is all that matters. Period. Where you make the HP is what makes the car fast. If you aren't making enough torque on the bottom end then your HP is lower as well. HP is a measure of WORK BEING DONE.

Everyone says that "torque wins races" and they are wrong. It's all about HP. You have to make as much HP as early as possible and as much as possible. In drag racing you must keep the engine in its best RPM range to make the most power. A 1000lbft monster diesel engine revving to only 4K will make 762hp (if torque curve is flat or peaks at 4K). A 500lbft gas engine revving to 8K will make the same exact power. If both torque curves are flat, then gearing will determine the winner.

When deciding to go KA or SR I think it would depend on what you are doing with it. You won't be breaking any records with a KA, and you won't be making as much power without serious work. Has anyone seen the exhaust ports? They are absolutely horrible on design and need some reworking to flow really well. If you are building it, then parts for the SR are more abundant. The SR will make more power, with a broad powerband and loves to be boosted. The KA has a somewhat early powerband, causing power to peak early before piston speeds get over 4000ft/min and power drops off instantly. If I had a KA I would keep it because it is cheaper. But If I wanted a faster car I would go SR. The KA motor is great, and you can build them to be even greater. But they do have their weakness in aftermarket support and supply. And it will take more boost in a KA to make the same power as an SR.

Coheed like I told ARJAY I will put money on KA24DE-T VS SR20DET of the same power the ka will spank that SR, as a matter of fact there is a company ( I think they are a bunch of spanish guys) with a ka 240 whos running the same times as the MAZWORX S15 with the Ve head , thats not bad for a poor flowing truck engine.

Acceleration is purely HP. I can show you some all motor hondas with full interior running 11s making under 180lb ft of torque. HP and when you make it is all that matters. TQ numbers don't mean anything, they just give you an idea of twisting force, not acceleration. Diesel engines always make more torque than a gas engine, but they won't out-accelerate them because of HP. The HP curve from a dyno will show you exactly how the engine will accelerate because that's what it measures (on inertia dynos like dynojet).

Best HP curve will always win the race.

If they are making the same power, then the gearing and driver will determine the outcome. Gearing plays a big part when getting the engine in the sweet spot and keeping it there. if you do in fact get a KA to run as fast as a built VE engine, then it won't be nearly as driveable. I have a KA here on an engine stand, I like the motor they are very stout. But you can't say that equal power on both engines the KA will be faster. It depends on more than that. The KA has a big broad powerband, but when revving high that KA will get walked on by an SR. The KA simply cannot rev high enough to make power on the top end and this is where the SR shines in comparison.

You can't take a big stroke engine: put on huge turbo, big cams etc and expect it to be as efficient as a high revving big turbo engine. Cylinder filling at high rpms is horrible on the KA in comparison. That is what it is all about: cylinder filling. There is a reason why nissan never revved their KA race engines over 8k.

At the point of where the top end takes over the race is done,track or street unless your doing top end pulls and then we will be dealing with different motors.

The 11 sec hondas are all top end.
