300 hp ka

Im building up a 240sx to race for the scca and i was thinking about 300 horsepower will be more than that little ka will ever need to smoke down the track. Now im still trying to learn and i dont want to swap the engine i like it as is. It's a ka24e so far everything is stock but i dont know where to look or what internals are best for what i need. Any sugestion on what company or what mods i should be looking towards.

I plan on buying a megasquirt ecu, Cams and valve springs (i dont know what kind or what to look for), maybe a stroker kit, and lighter race pistons, and lots of head work. maybe you guys can help me a little more as to were i should look for these parts and what i should look for.

300 hp NA?

You better do a LOT of homework.

Some of the GT3 KA24E's where pretty hot, but I believe they had a very large amount of cash to throw at them... Rebello Racing use to build them...

You might start there: http://www.rebelloracing.com/

They are the ones that build them...

These guys build a 231hp KA24E/KA24DE as well: www.paeco.com

Stage 4 - 231hp = $8400 for a complete engine + $800 core charge


Stage Four: These are high rpm engines designed for SCCA or drag racing where maximum power is paramount. They use 13 or 14:1 pistons, all-out racing cams, fully modified heads, Paecolloy knife-edged cranks, chrome-moly rods with titanium wristpins and valve spring retainers, oversized valves, copper head gaskets, and a number of other trick items.

yeah bro its gunna take a lot of money but so does swapping an sr or an rb and finding parts for an rb ill pass but josh i think you know what car this is and what type of racing im gunna do lol.

but the reason im not swapping an ls1 in there is cause the class i race in doesnt allow it an that engine would be just way to much for such a little car (I like to turn, straight at that even) but i like the Ka because it has the torque that the smaller 4 bangers dont have like all those honda guys out there.

What? I can't agree with this, an SR swap is dirt cheap now. I've seen people get pushed into a 300hp SR for just over 3k, that's installed, running and with the shop saying "if it messes up, we'll fix it at no charge".

What type of racing are you doing? You still haven't answered this question. . .

Oh and "all those Honda guys" out there, are running very fast low displacement cars.

In autocross, it's not about power, it's all in the driver. How fast your car is doesn't really matter if you don't know where your braking zones are.

In road racing, those same Honda guys, that you just tried to diss, are out there setting records in B18's with intake and header back exhaust in IT or ITC.

So I ask again, which type of racing are you planning on doing with the "SCCA" and what class do you plan on participating in? You've got several SCCA members on this site that can help you if you let them know this little factoid and you've got me, a former SCCA member and current NASA member, that would be more than willing to help class you. But so far nothing you've talked about makes any sense.

Yeah honda's are actually REALLY good cars. my brother has a teggy with a b18a, header, intake, aem fpr, aem fuel rail, crower cams and lifters and valve springs and retainers, aria forged pistons, bigger injectors, hes about to boost it and he already runs like low 12's. ****s a beast car. but yeah 300 n/a kaE? thats not gonna happen. I just kind of build a kade thinking, cam swap, intake, header, and a few little things would have me at atleast like 170 or something but im lucky if its even that..haha. your looking for almost double that..
