It is true, you take two exhaust cams, or exhaust and intake from 91- 93 put them on the 95 and up and it will get a bit more top end and mid range but loose some low end.

It gets the gain because our KAs came with 232/232 cams the 91-93 has 240/248. To use both exhaust cams you rotate the exhaust cam that you are putting on your intake 4 teeth counter clockwise on the timing chain and they should bolt up.

Its worth it if you can get them for cheap. It should pass smog just fine too.

cool. cause my buddy's got 2 91 ka. 1's in his datsun 510, and the other is just sitting around. so he ask me if i wanted it i can get it for free. the only thing is that he and i dont know how to put it in. so if its worth doin it i gues i'll see if i could find somebody to help me. thanks alot.

its pretty easy if you have some mechanical knowledge, you just have to get the engine to TDC, and undo the bolt that holds the sprockets on the cams, zip tie the exhaust sprocket to the timing chain so it doesnt move, on the intake one move the sproket 4 teeth counter clockwise then zip tie it to the chain that way it stays at the right timing, then unbolt the old cams bolt in the new ones turn them so the sprokets will go on and ur pretty much done.

and make sure you oil the cams when you put them in.

i wouldnt do it, my car has them and i think its gay i dont like the range it pulls at compared to the normal KA, but thats my opinoun

i wouldnt do it if you have an auto, but a manuel you can keep in in the good range.

what does 2 exhaust cams do? does it perform better than if you do intake and exhaust?

duration of the valves stay open longer. meaning more air/fuel into the combustion chamber

sorry but not sure what that meant.
