What cams should I change my Ka with to produce more power affordably? 95 240SX SE

I have been tipped off that you can take the cams from the Altima KA and put them in the 240 KA. The duration is longer on the Altima cams than the 240. An easy 22Hp gain with direct bolt on. Find a wrecked Altima to get them from.

Sorry guys if I was miss leading before, Take the Intake cam from a Altima which is 248 Degrees and a exhaust cam from a 93 240SX which is 248 Degrees and replace the cams of the 95-96 240Sx SE wich are 232 degrees. This can be done with no more mods depending on the milage of your motor.

Is there any factory cams that provide a power increase to the ka24de engines?

I looked up the cam specs for a 91 240 sx in the factory service manual.The intake duration is 240 degrees, the exhaust duration is 248 degrees. The intake cam from the altima should provide a slight power increase.

CAM CHOICE FOR 89' 240SX

I HAVE COMPLETED THE FIRST ROUND OF TESTING ON THE SHADBOLT RACE CAM(NOTE RACE CAM VERSION).
IDLE (DRAGSTER) ,YOU CAN HEAR AND FEEL THE CAM ROLLING. SO ROUGH THAT HAD TO WELD THE ENGINE SOLID TO THE FRAME OR EXHAUST SYSTEM WOULD HAVE BEEN DAMAGED. THIS HELPED ALOT AND SUPRISINGLY DOES NOT TRANSMIT THAT MUCH VIBRATION INTO THE CAR.
POWER BAND, NO POWER FROM IDLE TO 3500RPM, POWER COMES ON AT 4000RPM AND PULLS EASILY TO 7000RPM+ , WILL NEED NEW PISTONS AND RODS TO EXTRACT FULL POWER POTENTIAL, SINCE RPM RANGE I GUESS WILL GO INTO 8000RPM RANGE.
MY APPLICATION: SOLO 1 TRACK RACING, NOT FOR STREET USE
IMPRESSIONS: AWESOME POWER IF KEPT IN THE POWER BAND 4000RPM+, MY GUESS WOULD BE 15HP+ JUST FOR THE CAM.
I WILL HAVE MORE INFO WHEN I COMPLETE SOME DRAG RUNS, AND TRACK RUNS, AND USE WITH MY NOS SYSTEM.
