i have a b18c1 with these parts being installed
eagle rods
je 9.5 to 1 comp pistons
ef-1 springs, retainers
-its not sleeved
i plan on running revhard2c or drag kit.
How much boost can i run with a hondata and new injectors for fuel management.
and how high should i rev with boost with my setup. (the springs are rated for 10k)

 

I would stay under 10psi. on that setup.

 

It's possible to run more than 10PSI, BUT you would need some really good SAFE tuning, so you don't blow up your motor. I would say no more than 12PSI at the track and say 7 or 8 PSI while running around on the streets.

 

k thanks whats the most i should rev wit boost 9k too much
