Sema vg30det???????
 

any of u guys heard of a sema motor or sena motor its supposed to be the same exterior dimensions as the vg30de(tt) but a much stronger block, a different intake plenum, and an exhaust manifold for a single turbo instead of a twin turbo.....apparently the cylinders can be bored out up to 80-100 over to give about a 3.4-3.5 displacement. My overall question is should i go with that motor if it exists and this guy isnt tryin to rip me off, or should i swap a vg30dett and that motor up.... any and all advice would help greatly!!!!!!
