K, i’ll tell you exactly what you need.
For turbos, choose between a t28 (s15 preferably), GT28RS, GT2871r, etc
Stock cams will be fine
550cc injectors is good for over 300whp
Z32 Maf
You dont need an EBC, a MBC will be fine.
A FMIC is not really necessary if you can get an upgraded SMIC.
3" downpipe and exhaust is an upgrade anyone should do when going Turbo anyways.
Stock manifold is fine.
And Engine management. You can go with an SAFC but I wouldn’t.
It’s up to you whether you want to waste all the extra money but in my opinion, if you really don’t know how to get there, i wouldn’t do it at the moment.
It’s like wanting to buy something that you know nothing about or have no experience with.
Eventually you will learn, but when you do learn, it’s not something that you might want to do. (Buy all those parts)
