You know it’s kind of hard to find parts when you don’t even know exact parts you want. There is no mystical “cheap but good quality parts”, and there are reasons why you won’t find exact matching parts for your application.
Seriously do you think everyone that has installed a turbo on their car, wrote up a poorly worded plea for help trying to find parts. Followed by the fact they have no idea what the car can handle.
Neonglh is pretty much a god when it comes to 1st gen neons, there is no magic single link with every part you need. No one is going to hold your hand and point everything out. And most of all you are not going to find every single part you need in an exact fit because those that turbo a SOHC have to put a lot of effort into custom parts/fitting.
There is a reason why kits cost $3k+, not because they are trying to rip you off necessarily. But because it’s not easy to piece everything together, some parts will be custom fitted, and it can’t just be done from one easy to find source. A well assembled kit eliminates all these steps because most of the work has been done already.
You can’t just arbitrarily go and by random parts with out even knowing what you want. If you don’t know what you want how and the heck do you even expect someone else to point out where you need to go.
We are not all trying to be dicks here, but you have to have at least some clue as to what parts you are looking for and go from there. You have posed a question that is impossible to answer at this point. Like everyone else that has done something similiar a lot of work goes into deciding what parts to buy in the first place. However it would seem that you fail to understand that.
