I was thinking the dsm blow off would probably be best but anyone have any other suggestions.

This is not for a honda but rather a turbo intercooled 740 I am daily driving... hence why I dont mind putting a cheap blow off on it. This t25 is as weak as I thought I must say... although only @7.1 psi it pulls hard once it hits full boost.

 

my friend uses DSM bypass valves on most of the kits he puts together, you should be fine. if youre not making too much boost just look on ebay, you find odd stuff like old porsche and saab BOVs for real cheap, and they work too.
