I'm building a first gen 12a turbo car and will be right around 400rwhp... Does anyone have suggestions for which tranny to use and or what mods i can make to my 12a gsl tranny? Will a TII tranny hold up? if so will it bolt up to a 12a and will i need to get a new clutch? i have a new centerforce dual friction now for the 12a tranny....

Thanks
Josh
