Hey, I'm Chad. I have an EM1. just did the header (ebay Toda replica 4-2-1) also test pipe from them (click2buyhere). Of course it was PITA but got it on. Anyway, also did the SRI (HPS from TH motorsports), this was not too bad. (read instructions to get bracket rubber on correctly helped. What else? OH! did the clutch and passenger drive axle. Exeedy stage 1. SOooo now I have O2 codes to fix but the air flow in and out of the B16A2 seems to be a good move on my part. I'll get a P28 with basemap, and the conversion harness so I can dial in the mods and get rid of 02 sensor codes. Anyway, let me know if I can help. thanks
