sohc to dohc cams question

[undesiredshoe]

ok, im swapping in a 95 ka into my 90 240sx. I have the 91-94 parts needed to swap the engine. Im using the 91-94 ecu and such. Now, ive searched and found out that the 91-94 ka has better cams but a less aggressive tune. The 95 has the 232 cams but a more aggressive tune.

So im swapping a 95 with the 232 cams and using the less aggressive 91-94 ecu. How much would that affect power?? Is it even true that the 91-94 have a different tune than 95+??

The ECU isn't tuned for the cams, whatever it sees as air and fuel inputs is what makes it compensate for timing and ignition.

The cams in question are 91-early93. It won't matter which one you use.

ohh alright...so the "aggressive" tune ecu is just jibberjabber?? Then how come the hp rating is the same for s13s and s14s when the s14s have different cams?

S13s with 240/248 cams also have the SCVs. S14s do not.
