ok i got the twin 57's and thought i would like the idea of having a 6 speed with this setup but not really liking the coming in and out of boost in between gear changes and not really wanting to get it it put on me by a kb or whipple car cause of this so i've decided to go with a fully built turbo 400 with a trans brake and need some input on ideas for shifters and shifter location and also what converter would be best for this setup and any other input u have would be greatly appreciated....thanks in advance
