You'll have trouble with the tranny. The D16s supposed to be good for 160lbsft. This is sorta a rumour but it's seam to work out well. You can always put in a D20 (good for 200lbsft) but if your going all out it might be worth building the D16 up, It's probably lighter. Also I sell clutch kits that can handle up to 700whp so no problems thereOriginally Posted by fabricatorx
