HI. I have a 92 240sx with a 95 KA24DE motor. I have an AEM short ram intake, hotshot header, NGK Iridium IX spark plugs and NGK wires. I have cleaned the MAF sensor, intake maifold, throttle body and all the other fun maintenance stuff. I also have the timing advanced 5 degrees. I was just wondering if there was any other tuning you can do for these motors. I don't get any power at all until about 3500 rpms. Then the motor pulls hard until about 5800 rpms and falls flat on its face. Is there anything out there parts or tuning that could help fix this problem? Any help or input would be appreciated.

There are tons of places you can get parts. You just need to look. Hit some other boards like NICO 240sx forums, et....

 

thats about the right range for the powerband of the DOHC engines as far as I know. you should have a good bit of power under 3500 RPM, and then it'll hit harder and fall off after 6000 RPM.

at least mine does anyway

PDMracing has some cams out for the DOHC engines that are supposed to be killer on the street.

yeah, those are the cams i am getting in a few months. by the way, does anybody here have cams? if so lemme know how they are if they are worth buying thanx.
