As we all know the stock K series transmission is the weak link in any boosted K series car .I have always wanted to build a transmission for my boosted K as the stock trans has limited me on the size of the turbo I can/will run and kept me from competing at the drag strip for fear or breaking the transmission all the time .I must admit I know very little when it comes to this topic of built transmissions .I have installed a quaife in two transmissions now so I am somewhat familiar with the inside of the K Transmission but am looking for my best options for a street car that will also see the drag strip on occasion .What are the choices ? ppg ? mfactory ? I know their are helical and straight cut gears and helical are best for a street driven car as the straight cut gears are noisy .I want some advice from people who have actual first hand experience and knowledge on the topic .Please help me / us out. What will work best ? What are the different gears rated at hp wise ? Is a different/heavy duty final drive also necessary ? I am full of questions and looking for answers so please chime in lets hear it form those who know and can help !
