Planning to use ITR cams, looks like the appropriate vtec engagment should happen at about 4.5k rpm w/ these cams.

Main concern is about the IAB stuff? Is there a way around this? WOuld there be any problems w/ running the gsr ecu if I tune the fuel w/ a fpr?

 

as far as the iab's, you'll be fine
i dunno, you gonna run lean, and if you up it up with the fpr; timing will still be off.
bigger bores need more timing/
ill say get it tunned

 

Any one else have experience with this setup?

I have a b20b currently running in my car, just rebuilt a gsr head completely stock. I have an obd1 p72 that I want to use until I get it tuned.

Will this blow up in my face?

Thanks,
