How do I know which BOV to get?

 

I found a good article on the "math" of BOV to Turbo size and capabilities in a previous unrelated search but I cant find it agiain

From the general definition and some articles and videos it seems the BOV has no "Specs" i.e. there appears to be no BOV to Turbo ratio.

 

It looks like its a matter of where the "lag" ends up in your setup. It seems to be more a fine tuning game with different spring types.

 

Am I right?

Greddy RS is plenty.

 

I also agree that the Greddy RS is more than enough for a street car.

I had one on my '88 Rx7 with a hybrid T04 turbo and it was more than enough for that car.

 

I'm sure that the Greddy S type is even good enough for any factory nissan turbocharged car.

 

Find a Greddy S or RS or an equivalent and you'll be set. They are adjustable of course as well as the RS can be recirculated back into the intake to get rid of the lag between shifts and the slight rich mixture that is the cause of the lag.
