Guys. If you ever obtain a JWT POP, the 2000 SR20 motors use the same MAF that the 2003 SE-R uses. I installed the POP in about 15 minutes, it was very easy, and no engine temp sensors to deal with!!! I thought it would be too big next to the battery, but it fit fine and there is very good play in the stock plastic rubber piping to allow it to move freely. The sound is very good with the throttle hammered. I still have the stock exhaust and no other mods. The sound is fairly loud from the engine bay. I really don't feel any more power from it, but maybe the ECU must adjust to the new airflow readings. Anybody Dyno the POP on the QR25 with no other mods?
Thanks Chris 92,03 SE-R

I would not expect many gains from just a POP chager, maybe 2-3 whp. As for the MAF being the same, not quite true, the adaptor plate for the WAI on the MAF uses the same bolt pattern for most Nissans (at least in my experaince). The actualy MAF itself is most likely a diffrent part number. Check NPM mag in the early days I think the first porject specv had a JTW POP chager.
