    A:  Yes they will by increasing the amount of time the valves will be open, which in turn leads to more top end, which in turn leads to more HP!

• Q: AVCS Head   Lucas Mullins4 years ago

  These cams should work with my 2012 WRX correct it is a AVCS head and the Tomei Pon Cams and GSC Cams are the same part numbers. So that being said will these work with the stock cam gears?

• Q: b25 vs w25  FrankF5 years ago

  I bought b25 heads for my motor build. I have a 2011 sti with davcs. The heads i bought(b25) have these cams installed. if I swapped parts over from my oem heads(w25) will I be able to run the B25 heads with these cams installed and be able to use the DAVCS in my car or will I need completely new heads/cams,

    A:  These cams are designed for the single AVCS motors only and would not be able to work with DAVCS motors as there is no prevision for the oiling ports for the DAVCS.

• Q: How long does it take to install these and is a engine retune needed right away  jim.springer032765 years ago

  I'm looking at dropping a set of these in my 05 STI, about how long is the install for a person with above average mechanical skills and can the car be driven for a short while before being returned or is a return needed at all? Thanks, -Jim

    A:  The motor needs to be pulled to do the install, so I would expect a better part of a day. You will also need to check your cam to bucket clearance and if your buckets are worn you will need to purchase new ones. A tune is a absolute MUST and needs to be done right after install.
