The KA is not a fast motor in stock form, however if you build it, it can be one fast ****. The SR is also slow in stock form (I don't think a mid to high 14 is a fast car)...the SR is faster than the KA in stock form, but the KA dollar to dollar will beat the SR in performance up to about 500 rwhp...after that, the KA hasn't really been taken much higher, yet some SR's (after sleeving, stroking, etc...) have reached 7-800hp. If you're looking for a respectible 1/4 time with something that is reliable and doesn't require a lot of money to build...then play with your KA (especially since the mileage is so low)...you'll be happy. If not, sell your turbo parts and go with another engine. As said before, whatever makes you happy is what to ultimately go with...I am very sure that the KA will make you happy, but then again, so can the SR...I just don't see justification in $3000 for a 2L motor when you have a 2.4L that can be built up internally and with the head for $3000.

Ok have a KA 97. How much i'll be spending to make it turbo?..
Minimum budget.
Bottom price = ?
HP = ?

Thanks.

 

Depends on if you want a full build or just to run 7 psi...

i thought you couldnt get much from the ka. but from what you guys are saying it looks like that it does have potential. is it hard to turbo the ka. i dont wanna go crazy on horse power. but i wanna run atleast high 13s on the 1/4 is it better with the ka or the sr. the miles on my ka are really low

 

Turboing doesnt cost that much..it will cost just about the same as a SR with a couple upgrades, and have even more HP then it. Search around the net for some pricing..its been covered before.

 

and will my stock internals handle it? if i run lets say 5-6psi?

 

you can run 7psi on the stock internals..and get around 230 at the wheels. Thats what I have heard at least.

 

im starting to think about turboing my on ka than. if its not so hard then why do so many people do the swap?

 

Yea, turboing the KA isnt that hard. Just gatta know what ur doing. And people go for swaps because thats what everyone always talks about, usually the first question that a person asks you "Do you have a SR in there man?" Blah blah..over hyped. Its in all the magazines..go SR you will never go back. Look beyond the media and you will see the true potential of the 240

 

230 rwhp on the KA means that you will run a low 13 1/4 with street tires and a LSD... It doesn't take much at all to get a 13 second car with the KA...it can even be done NA...of which I will be building soon, but I have to say I'll miss the sound of the turbo behind the power...

The SR is lighter. And for 6000, you can have 250 RWHP very easily going with the SR. That's including labor, an electronic boost controller, and most bolt ons. That will get you into the very low 13's. Now the KA can also be built up, but the turbo's for it are a little more costly. So yeah it'll be a little less, but not quite as quick, and you'll pretty much be at potential. The KA is a truck motor... where the SR is truely a race motor. If you bought a new turbo for the SR, you would dominate, low 12's or high 11's.

 

The SR is a daily driver economy engine in Japan...it's not a Race engine. The RB (Race Breed) is the only true race engine made by Nissan. The SR weighs maybe 30 or so pounds lighter (not sure about the amount, but it's nothing to go gaga over). Turbos aren't more costly for the KA than they are with any other engine...it just all depends on where you buy your turbos and how you build the kit...if you go with XS or Greddy, you'll pay out the ***, if you build your own kit, you'll spend very little The SR also loses most of it's hp at the same time that the KA does, so revability is not really an issue...even the KA with new internals can be balanced to run 10,000 RPM's if you wanted to, but there's really no point. The KA with 250 RWHP will beat a SR with 250RWHP because the KA produces quite a bit more torque than the SR due to its long stroke. The KA is a truck motor that has been built over 500rwhp on stock headgasket... Just as well, a full rebuild of the engine runs about $2000 with new pistons, rods, headgasket, ARP bolts, valves, springs, retainers etc... then you boost to your heart's content. Also...250RWHP is enough to hit a mid to high 12 1/4 mile if you know how to drive. Lastly, you can build a N/A KA over 300 RWHP for less than $6,0000....

Preach on night, If you use that 6k towards boosting the KA, bye bye to the SR. The KA has much more torque then the SR.

 

LoL, and God Said, let there be torque....and he created Nissan, and IT WAS GOOD!!! But, there was evil in the heavens, I tell ya, PURE EVIL....and God shunned it to earth and called it Honda and gave it no *****. God vowed that forever and always Honda would be stomped into the ground by his great creation Nissan...and so it is written, so it is done. Torque beats all!

Then God said, let there be two different masses for the 180SX, so he created the SR and the KA. The SR was like the water and covered 75% of the 180/240 population, and the KA was like the land with 25% of people building it, yet the KA had more torque, but just like the darkness, the light cannot understand it. So those who build in the darkness (haha, NIGHT) build the engine of torque, and those who build in the light and follow the majority build with HP and low displacement.

On the 7th day...God rested and watched fools like us argue out each engine online....and it was GOOD!!!!!
