KA-t VS. RB25 (or something that will beat a srt8 300c) - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

toast240sx · 07-31-2012, 01:41 PM

I need to know which of the 2 engines would be better to get and build to race a Chrysler 300 SRT-8... Obviously the RB would be better but would it be better to just build the KA i have now or just buy a RBx and build that??

DJ-of-E · 07-31-2012, 01:49 PM

My vote would be to buy a Mustang GT. Then again, I'm not a fan of using a 240sx as a drag car.

toast240sx · 07-31-2012, 01:52 PM

well not just drag race but like running them on the interstat

Ratpack_Chad · 07-31-2012, 01:52 PM

This should be interesting.

Highway Riding · 07-31-2012, 02:12 PM

So you got owned by a SRT-8 and wanna build something to romp on it? OP it's ok it was a V8 it happens...

toast240sx · 07-31-2012, 02:16 PM

no my buddy just got it and thinks its the best thing in the world and i want him to get stomped by a tuner. ive got a bone stock KA right ow that i can start building but i wanted to knowif it wuld just me money to go ahead and buy a RB

Im soooo happy this was posted haha my boy loves his srt-8 jeep and thinks its a rocket ship (it kinda is) but my ka will be boosted in about 2 weeks, just bought a full kit for it so i'll let you know how she does against him haha but if you have the dough rb all the way but they ain't cheap

starfire240 · 07-31-2012, 02:22 PM

You can build anything to beat a v8. Where there is money and will power, there is a way.

Sileighty_85 · 07-31-2012, 03:41 PM

hmm let see, an engine that can handle up to 500 stock or an engine that will blow up around 300...

But really depends on how poor you are.

Stock ka's can hold 500. How long though is a different story but it's been done numerous times. The stock block record is like 570 something.

if it blows up that means it cant hold it....

DJDANGER24 · 07-31-2012, 04:00 PM

^^What he said, a stock block RB with GT35, good EMS and supporting mods can walk on a lot of high powered cars.

You think this car can take an SRT8 ?

shiftdrift · 07-31-2012, 04:18 PM

i mean, a stock KA with a t28 at 10 lbs could probably walk an srt8 300....

said car, stock ka, t28 with cobra maf and JWT ecu.

alixander2012 · 07-31-2012, 04:37 PM

Bet that supra's like "Hey man you cheated, or hey man I didn't hook the 60 ft." lol

zerodameaon · 07-31-2012, 05:03 PM

What does it matter your racing on the streets, hopefully one of you will get pulled over and arrested before anyone gets hurt. Toast go read the forum rules and get back to us.

shiftdrift · 07-31-2012, 05:05 PM

oh no street racing, the thing that everyone does....but everyone acts like they don't do.

godsmack · 07-31-2012, 05:06 PM

^ beat me to it. just go buy yourself a damn honda and be done with it

booey13 · 07-31-2012, 05:11 PM

Exactly why I'm building a 240. To "stomp" jeeps and 300s. Smh

zerodameaon · 07-31-2012, 05:20 PM

Its more of the "Hey look at me I want to build my car to street race my buddy."

spooled240 · 07-31-2012, 05:38 PM

these american cars have what, almost 1000lb on our s-chassis's? lol Just match their 425hp and you'll smoke them

some dude in a jeep srt8 was revving at me today and I though of how I could beat an AWD V8 car like that.... I'm thinking a big turbo and playing catch up

booey13 · 07-31-2012, 06:35 PM

It's all in the tune. Not much you can do when you start bending rods. Stock ka's can hold 300 easy unlike you said.

Yes it is all in the tune. To an extent. You cant put a 500hp tune on an engine that can physically only handle 300.

Yes you can do something about, its call not being a cheap ass and doing it right by replacing the rods and pistons, Rather than slapping a $400 turbo kit on a 150,000+ mile engine.

godsmack · 07-31-2012, 06:41 PM

he's just saying that it's more effective to go rb25 than to build a ka and worry about it breaking. they will hold 300hp but once you start going above 400hp you need to start doing too much work to them in order to hold together for awhile.

stinky_180 · 07-31-2012, 06:46 PM

rofl... just put the engine from the Chrysler 300 SRT-8 into the 240sx

booey13 · 07-31-2012, 06:48 PM

I guess it all depends on your definition of effective. Obviously overall engine condition will play a major part and iirc op was worried about cost.

Not to get your panties in a bunch but you'd obviously want to do the same when doubling the horsepower on a stock rb25. If you want to do things "right" that is. And as I already said op mentioned cost being a factor.

lol the guy is talking about wanting to beat a Chrysler 300 SRT-8. Which is rated at 425 crank, so with the power of math we can see that there is no need to double the power capabilities of the RB seeing that it can handle over 500 stock and that a S-Chassis with have a better power to weight ratio.

So your argument is moot.

Thanks for playing.

Jeeps are even slower than that hahaha my buddies only has 411 and he has a full intake with the borla exhaust ( jeeps are slooooowwwww) even a ka with 350 should beat him trust me. my cousins z28 camaro has 310 to the wheels and beat this jeep twice on the taconic. if you want to beat a jeep and save money go ka aha

Well, heres the kicker about RB25s, I know enough folks in Okinawa who were pushing over 500-600hp on a fully stock RB25 bottom end. To get a KA to push over 300 reliably, good idea to change those pistons first correct?
