Broke my 9 1/2", said the turbine is broke. Place I sent it won't touch it. Originally a Tci, and I may send it back to them eventually. Looking for what everyone else uses.

All the companies I called we're very helpful. But there are a lot of opinions.

Background on the car

69 runner 3760# + my 240#
511 10.5:1 with standard port SR's ported by MCH
260/266 @.050 on 110 in at 106
Six pack or sometimes a tm6 with a 1050 annular
4.10 gear 28" tire.
Shift 6200-6300

It's been 10.92 @ 123.4 through 3" mufflers


ATI recommended a tight 8". Sounds a little wild for the car??
Coan recommends 9" sounds about right
PTC 9 1/2, really like what he had to say.
Turbo Action actually recommended a J. Although they no longer make them.
Dynamic I have absolutely no interest in

I actually have a J on the shelf and am going to try it, I do feel like It may be a bit loose though and give up some ET given the low shift points.

Thoughts, opinions, experience ??
