Ive destroyed to many 1st gen dsm turbo manifolds from diy porting. Tolerances are just to tight for diy porting (my opinion). After the 4th or 5th manifold i took it to a pro. Took me awhile to find one who would let me get my hands dirty with em. But found one and learned a lot. Flow testing is a must for max gains. I recomend light porting for the diy. Just port to match up to your gaskets. For big n/a gains displacement is key. Stroking is slways nice for the low end torque. Stroked my 4g63 to 2.3 and turbo reached full boost 2500 rpms sooner. You even thinking about trying to keep up with the F/I cobra? If so i believe custom work is gonna be needed. And your gonna need to buy a trailor to tow it to the track.
