Speedtek Close Ratio Gearset for Nissan Skyline GT-R

Speedtek close ratio gearset for R32 GT-R

I have noticed the guys from Speedtek for several years. They had a well priced close ratio gearset for the RB series transmissions. RB26 and RB25 FS5r30a.  I wanted to try out a set, and recently I was in contact with them.  The OS88 transmission I had in Nismo #500, went into/is going into Big Bird 2 so the trans in the Nismo was just a stock R33 transmission.  In theory a stock trans, making near stock power with a sprung hub clutch should be ok, but too stock is too boring.    I also have a Getrag V160 from an R34 GT-R, but I will keep that for another project, or another demo car here at Toprank Importers.
