Yup, just used the solstice as an example for the power output partI've done my research on that AR5 when I was going to use it in a Firebird build up in our shop. The truck versions also use a different gear ratio in 3rd than the Sky and Solstice versions. The truck versions also have a different shifter position and the "GM" AR5's use a 26 spline input, where as the Isuzu one is 24. The diameter is 1 1/8 instead of 1" but they use a smaller clutch disc than the Trooper AR5 setup. Also their bellhousing bolt pattern is different on an Ecotec engine, similar to like a 60 degree V6 but not quite, it's special. And BigSwede, what kinda clutch are you running in yours? I know my MUA5 held up nice on just 33's in the Rodeo and my random trips for over a year but nothing like what you put yours through
