So I just recently bought a 200sx with the non-turbo SR after having owned an S13 with an SR it in.
Aside from the same lifter tick my old 240 had, it runs like a champ.. Until it warms up. When its cold it feels great, it has power in all gears and can chirp second. But after it warms up it feels like it has limited power.. It feels like when I'm accelerating it is as if I was only partial throttling it, no matter how hard I mash the gas.
I have researched and found similar cases where people thought it was anywhere from the maf, knock sensor, or oxygen sensors. So before I go out and spend big bucks on the above mentioned I thought I'd post my own thread.

Had the same problem, i was even getting knock sensor malfunction CEL so i replaced it, got a good amount of power back. Clean the MAF with (maf cleaner lol). When your car warms up it changes how it runs on the ECU so maybe there could be something. Thats all i can think of.

Update:
I fixed the knock sensor and got some of the power back, especially when cold. I can really feel the difference when it warms up now. Its sending a cel now. It might be useful. I will be checking it out tonight.
