Need to know what gets eliminated and doesnt swap over from stock IM to the Blox IM. Since there are less vacuum nipples on the Blox IM. I found a couple write-ups but didnt really show what gets hooked up to where. They were more removing stock IM and reinstalling Blox IM.

Also, would I need to get a different ecu? I heard that but wasnt sure if it was necessary. could I just get my P72 chipped to deal with the lack of butterflies in the Blox IM?

 

I'm also wondering about the ECU situation. I have a 94 GSR; I plan to get either the Blox or Skunk2 intake but I want to know what's up with it. As far as I know, VTEC engages at 4400 with the first butterfly valve, and then at 5800 the secondary engages. Does that mean that if you put another IM on, VTEC will simply kick in fully at 4400?

I read this and got all the info I needed, except for the ECU issue.

 

Id like to know tonight so I can order the ECU tomorrow morning. my car is going back together this weekend

 

as far as the blox I.M. goes sorry i have a skunk 2 manifold and everything was pretty simple. for the ECU its better if u get a hondata s300 chipped. u dont even touch the p72. it worked for me and tuning helps alot more. u install it and they program it for u
