recently i broke the 5th 6th shift fork and my car is in the shop now. car is stock now, but my future plans include pullies and eventually a kb. with that being said i want to upgrade the tranny now to handle 600ish rwhp. my ideas are spec 3+ clutch 26 spline, fidanza alum. flywheel, liberty 26 spline input shaft, hardened TOB retainer (which one is best???). looking for suggestions, are there better parts? anything else i need to upgrade, or any other problems i may come accross. thanks!!
