stock outlet of body is supposed to be 70mm but the opening in plenum is 75mm i think. do not get one bored out more then 75mm. it will either bind(thottle) or you will get disturbed airflow as it hits the plenum or you will need and adpter to prevent binding and it usually just knocks the bore back down again before entering plenum.

Got my new bluetooth OBD2 scanner today. Hooked it up after I got home, and noted stored codes. Deleted old codes, did a couple trips here and there, and when the SES light came on, pulled the codes. Only two remain: The EGR code (likely stuck open, and I have another waiting to get installed), and the Cam Sensor code. Gonna make sure all my wiring is good before I replace that.

The program on my phone to sync with the OBD scanner is friggin sweet.

swapped in my NBS master cylinder.

AWESOME!!!!! I recommend this to everyone with the squishy OBS brake pedal.

My pedal is now very firm.:peace:

You need an AGS BLF-26C brake line adapter from AutoZone and obviously a NBS 1500 series master cylinder.
