I had the same hopes and dreams for my car and then realized that it takes forever and I don't really have much technical know how.

I would firstly take that crap D-series out of there and throw in a B18C. Rebuild the internals for turbo and then turbo it. There is so much to possibly do but you got to realize that it will take a ton of time and you have to determine if you want your car to be your money pit for the next few years.

But by the sound of your post, you need to research your options and determine which ones would be best because you can't just slap a bunch of expensive aftermarket parts onto an engine and expect it to go fast.

Good luck though.
