Blow off valve

If I'm going to by a blow off valve for my 92 trubo gsx, what do you guys reccomend?

Read the faqs. Many people run many different kinds and most of them are great. It all depends on your budget and what you are looking for

For everything up to say a 60-1, I still think the 1g BOV with the Gus Mod is the best option. If there is no need to recirculate because you run speed density or a MAFT, then the Tial and Sard are hands down the best BOVs I've ever had the pleasure of working with.
