Blow Off Valves

[5150Neo]

I am planning to install a BOV on a 91 Esprit. Does anyone have suggestions on a model or manufacturer. I've been considering Greedy or Turbosmart. I am also looking for tech info such as; do's & don'ts with the install, what models have proper spring tension, what models have a base suitable for mounting on the left side of the intake plenum, etc. All comments welcome.
