I would like to fix this peice of mis-information
The JDM camshafts doesnt offer any gains of US DSM engines. why or how do I know this ? because its my job ! The JDM cams is the same on the intake as the 1990 US 4g63t only (1991& up are better) the exhuast cams on any JDM (this will get you going) is the same as any "NT" exhaust. shorter duration and lift than any turbo cam.
I guess you can say I spent a little time measuring...
