I am a standard transmission specialist and I make my living by building and selling standard gearboxes on a full-time basis. If you can not make every shift at wide open throttle, you have ALREADY LOST THE RACE!
Do any of you know about or remember Ronnie Sox of Sox & Martin Racing Team with their red, white, and blue Plymouth drag cars from the 1960's? They were sponsored by Mopar. Ronnie was known as "Mr. 4-speed" because he drove a stick car which was pro-shifted, and it sounded like an automatic as it went down the drag strip. He never let up on the throttle to shift.
Ask yourself what happens to the spool of the turbo every time you let off on the throttle to shift, and then floor it again.
With the stick, it needs to be modified for face plate engagement such as provided by Jericho, Liberty Gears, Swaar Automotive, and others. Now one can shift at wide open throttle and never miss a shift. Just don't try to drive this combination on the street because it sucks big time without synchro blocking rings. That is why they are known as crash boxes.
Don't waste your time and money on a standard shift for your turbo car. I gurantee you will go slower.
