It's the stuff that came on the Japanese version of the Protege, called the Familia. Also goes by JDM (Japan Domestic Market).
JDM cams might be worth 5 hp or so, it comes at the top end and sacrifices a bit down low.
Isn't the JDM intake manifold the same as the USDM MP3 intake manifold?
The JDM pistons have a higher compression ratio but require custom engine management or the extremely-hard-to-get JDM ECU.
Someone (Linuxracr?) did the JDM swap and found it didn't do much w/o the proper engine management.
You can get the stuff at corksport or srmotorsports.
