This includes a new Toyota oil pump. We then take that and modify to increase pressure and prevent the front main seal from blowing out.
What is done to it?
We shim the main pressure spring
Drill a larger return hole
Drill and tap 3 set screws to hold front main seal in
Shorten (tighten) main seal spring
New internal micro-finish comes standard. This is highly recommended. The new out-of-the-box Toyota pumps are now of extremely poor quality and this is the absolute best way to guarantee optimal performance from your oil pump to supply the life blood of your motor.
