Tranny is good for turbo but bad for All Motor, this is in reference to the LS tranny. Well you could just put a vtec head on it. This question is a little vague. Could you also include what you want to accomplish in the end or give us the reasoning for this?? Do you want fast time slips, daily driver, all race, more tq down low, more top end, NA setup, etc..
If you narrow it down we can narrow a target area for you and recommend something.
