I hear alot about the numbers on both the ka and sr. SR=205hp KA=155
With that said, for people who have driven 240s with both motors, is the extra 50hp that the sr has very noticable? I realize that the sr is trubo so it has lag, but in general what is the feel of sr. I am considering putting one in if i can do some fund raising/work. |

i personally felt a difference between the 2 when i had my swap done. the turbo lag isan't that bad, it spools fairly good. just to compare the two i did a rolling start in second gear with a friend with his Ka 240 and i pulled away instantly with no problems.
i don't know the 0-60 times for both, but i feel the turbo lag isn't a big deal.

I dunnow about the lag on the t25s, but i couldn't feel any on a t28 sr and that turbo is a bit bigger.
50hp is very feelable. However, if you plan to run no more than the stock boost (although it's kinda hard to do once you get addicted), turboing the KA will be way cheaper (ofcourse assuming u are a do it yerself). I'm right now in the middle of building a 215hp/220tq KA for well under $2000 and from what i understand a descent s13 sr would cost like $2500 (is that right? w/ shipping ofcourse...) |

I'm sure your car is very capable of doing solid times. And I was just recycling numbers from old men who think they're race car drivers <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/hehe.gif" border="0" valign="absmiddle" alt=':hehe:'> You're running a slushbox with a turbo (200hp), your time should be pretty solid. Watch the tree for green and step on it. The first gear on an S15 sucks, when driving one you have to shift to second almost immediately. The stock KA automatic tranny has much taller gears than that of the 6-spd. Also of note, is your 200hp rating. Is this at the wheels? Because, from the factory, Nissan rates its S15 250PS (or 247hp or 1PS/.99hp) at the flywheel. Doing the conversion for 15% hp loss to the wheels 247 x .85 = 209.95hp which is only 10hp more than your KA-T -- not 50hp. Just an observation, not trying to start anything. Regardless, that is an amazing time, especially for your p/w ratio. What kind of setup do you have? Wheels/tires etc. I haven't been able to test my 0-60 as my car has some gremlins who don't seem to go away. -ty |

My setup is just a basic, bare-bone system cuz college came entirely too soon. Anyway, I am running 4.35psi on a stock engine, exhaust, fuel system, and auto tranny. Also, it is technically 195hp *calculated* at the wheels. That is based on my 1/4 mile time and weight of my car.
Also, since you have inquired about wheels/tires. Stock SE alloy rims and Zrated Dayton Daytonas *(And I fuckin hate them!<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=' ![]() -Jeff

Ugh... that last post... I'll just forget I read it, as hard as that may be <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/music.gif" border="0" valign="absmiddle" alt=':music:'>
The problem w/ comparing the KA and the SR stock for stock is that they never stay that way. If you were going to swap just to have a stock SR, it would be 100% not worth it. You could do $1000 worth of easy mods to the KA and be really close to a stock s13 SR in terms of performance... for $1500 and hours of work less. The reason for doing the swap is b/c of what you can do from there. While a stock swap will net you under 200 whp, $1000 worth of bolt ons can take you over 200 and $1500-2000 in mods will have you running w/ Mustanks. In short, the swap (or a KA+T) isn't for someone who is looking for 200 whp and an end, but rather as a beginning. |

I havent talked to nissan on this one but i really doupt there car was designed for anything other than to sell alot to people who want a cheeper sports car. Drift, drag, show or what ever thats all about the owner and what he/she wants to do with it. its like saying a civic is a natural drag car, its not its and econobox that hapens to have potential just like the 240. A few years back none of us would have thought a a cheap ass civic would ever run 8's-12's. I cant even count the number of owners i personally know that have hondas running in the sub 12's its just to many. point is its all about what you wanna do with your car. Im gonna try get a bit of drifting out of mine and some autoX and when that track is closed im gonna hit up the drag strip, and when the weathers to cold for that ill be as the show and shine. Have fun guys, do what ya want with your ride, just no rice

Hippo speaks the truth again! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>
When I first got my SR put in it was bone stock (and I mean stock) I had the stock airbox for goodness sake. But the difference was huge from the butt dyno. And my KA was bone stock also. Defininately faster but not nearly fast enough. So yes it is a good starting point to build and yes I can kill stock and slightly modded moosestangs all day. FYI I raced a SVT Cobra the other day and it was pretty close but the top end of the SVT suprised the hell out of me

drifting is not the fastest way around a corner... thats why the "drift king lost his race on the curcuit"
grip driving is fastest.. but not as "cool" |
