Decided to go a different route. Brand new G-series transmission reinforcement plate. Bought it during the last GP. Comes with instructions on how to machine the case.
$275 shipped.
What is the main purpose for this and also is there any other part needed or suggested to complete the install? I remember going through the gb but not paying much attention since my car is not making much power but now I'm considering turbocharging and might want to be safe.
The plate reinforces the input/output bearings, prevents the shafts from deflecting and stops 3rd gear from shearing. If you plan on going turbo, it's a good idea to use this. I have personally sheared 4 sets of 3rd gear over the last 8 years.
