you can crush the MR bov also. i could be wrong but i believe that the stock EVO bov's are made by Tomei.


the loudest bov's will not necessarily work the best unless you have the HKS EIDS computer &/or a standalone ECU. FYI, the stock bov leaks. just buy a recirc kit until you've added some power. bigger turbo later, switch it to VTA.

but what do i know, i only have 2 evos...

 

i need help with getting a BOV as well. i have vishnu stage 1 ++. i need something that will hold up to 27 psi. any suggestion for me? i heard greddy type r were good. anyone have this BOV?

 

i think the RFL will hold 30PSI, however, at that level you will want an externally wastegated turbo anyway.

 

whatz everybody's take on the greddy RS BOV and the Agency adjustable BOV? i know their both new but these are the two that im somewhat interested in.
