I doubt a mildly boosted KAT will ever hit the limiter on anything but maybe an oval. But you can remove it by swapping to a JWT ECU upgrade or some kind of stand alone engine management. Greddy lists a Speed limiter removal device in their new catalog that says it works on most Toyotas and Nissans. Not sure if it will work on any KA's. It's universal and has DIP switches which I am guessing is set according to the application.

ok thanks my friend runs the greddy e-manage and he got the speed limiter off of His SR. i was just wondering becase he hit 140 mph in the back streights at VIR. and i was wanting to make my 240 a track car also but i want to boost the KA. but manly would the KA take the high speeds?thanks

what would cause a KA to not be able to handle high speeds? are you talking about the gear ratios? i think 5th gear hits red line at about 140 mph

Maybe he means engine speeds? (rpm)

if you could theoretically actually reach that speed, what would 5th gear redline at in a car with a stock rear end?just curious...

you could easily reach that speed in a boosted 240. and you have to specify which car youre talking about with a stock rear end.

people can reach that without boost jsut not on a track. even at 8psi i can pull up to 120 pretty damn fast. i havent gone much faster sincei start leaning out then. my new fuel system will be in very soon. i would love to get into road racing. englishtown jstu built a road race track right?

thats for the 240 with a stock rear end. i calculated it awhile back and it was either a few mph below or above 140

but that would depend on your red line too...guys with ca18det and 9k redline claim 160 mph + top speeds....

There is no reason the KA can't handle high speeds. It's just a matter of will the KA have enough power to get it to a high speed. The more power you make, the higher speed you can reach, given the limited amount of room on a race track and the limited gearing as was already discussed.

It sounds like you don't have much experience with track racing though. You may consider starting with suspension and brake upgrades and getting out on the track before you start boosting. Too much power and too little experience on a track can make for a bad combination. Once you get confortable with driving on a track, you'll probably have a better idea of what kind of modifications and power levels you want. There are several techniques you will want to get confortable with when driving on a race course. Learning to use them is a lot easier and safer when things happen more slowly. As you make your car faster, you can start to grow into your car and road racing.

im sure i can handle the power of a kat. cuz im not going for a lot of HP im aiming at 250whp or close on stock bottom end. and befor i sold my GST i made 350 with stock bottom end but it was front wheel drive. but i had to sell it to pay some things off. but i love my stock 240 way more then the GST.yeah i dont know alot about track racing i was just looking into it. i think that it would be pretty sweet.thanks guys for the replys

Driving on a race track takes driving to a whole new level. Regardless of how well you think you can drive on the street, everything changes on the track. Few people havce such reserve as to humble themselves before they get out onto a track. Track racing puts more stress on the car than any other racing I know of. Consider that everytime you are doing anything, you are trying to use the car's full potential. The motor, brakes, and suspension(especially tires) are truly put to the test. All you need is for your brakes to fade and you not to realize they are fading to put yourself into a wall. And with a turbo, you car will hit higher speeds, particularly in long straights. This will require you to brake more before entering a turn. OEM brakes are barely adequate for even some slower tracks. A turbo will considerably make things worse. Consider it a way to work out any bugs in the suspension and brakes to ensure that your car will be in good working order to handle the strees of having more power. These are the more important things on a track anyways. And even without a turbo, road racing is quite fun.

I've heard several stories of people rolling or destroying their cars their first time out on a track. To name two, there was a WRX that I heard some kid rolled. I guess he though AWD meant he can go as fast as he wanted through a turn. The second was a Acura CL. This one was a kid who basically ran off the end of the back straight on the streets of willow. The turn entering this straight is a banked increasing radius turn that basically allows you to slingshot your car down the straight. It leads into a blind downhill chicane. Well, he launched the car about 20 feet in the air and when he landed in the dirt, all 4 tires blew, the suspension bottomed out and not one panel was left straight. Keep in mind none of the panels hit the ground, which means all the bending was because the frame bent so badly.

The point is, you can't get into any kind of racing with the mentality that you can handle a certain amount of power, regardless of what you've driven before. Driving something on the street and on the track are very different experiences. It's a lot of fun. Unless you wreck your car. And keep in mind, most insurance policies do exclude damage that occurs on a race track.

My compliments midnight. You have a good attitude. You hang on to that. Driving is a finesse game that takes a clear head to excel and progress. If you listen to these guys (well, some of them) they might be able to give some good tips. A few guys at my home site http://www.240sxforums.com use the ka for track and drift, and they say they have wiped the floor with other sr's at the track. So any things possible with $$$$

you also may want to look at my site under the "race" section i have lots of times posted road racing against a variety of other cars on some large and small road courses...suffice to say the KAT can keep up/beat with many of the best cars produced

C-Kwik makes a good point. Turbos are very finicky to drive at the limit. Especially if you're running a turbo setup with some lag. You need to get on the gas differently in a turbo than an NA car when it comes to things like hitting the apex.

To kind of expand upon what C-Kwik has said, definitely get your suspension and braking points dialed in for the track you drive at. Keep the car at some non-laggy, low boost setting. Once you're comfortable with a more or less, lag-free NAesque driving experience... then start cranking up the boost, and dealing with all the dynamics of boost curves, snap oversteer, and the other joys of turbocharged automobiles.

any idea what the top speed should be with that 5th gear? kinda sucks to run out of revs instead of power

Could also bolt up a S15 SR transmission ther a six speed but also maybe weaker from what i have heard

Congrats on the good results. The fact that you were within .500 of guys running Hoosiers says something. Is there some reason you're not running slicks?

the alternate 5th gear set they offer is a higher ratio than stock. that means its got an even lower top speed than stock
