Yup Yup. The '07SL55 has a 80mm TB and it sells for $250. Then, we have to take the housing and shave the mouth to match and may as well polish the interior while it is off. The bulk of the project is labor. Even I can swap out the TB, since it is just 4 bolts, but you gotta take the SC out to get the housing off. Then, the machine shop charges to do the shaving and polishing, and then install it all.
Jrocket: it ain't dead. It is coming up.
I want to have a good plan for all the mods before I begin. I'm just deciding on pulley and ECU tune sources for now. We have everything else and I'm hoping not to pay more than about $5K for 100hp gains.
