I am curious, and interested in building my own custom turbo setup, mainly because of cost factors. i want to run a t25 turbo. What other parts do i need? What custom work would need to be done?

 

You would need a manifold for the turbo...

 

you will need the turbo, a manifold, some decent plumbing, upgraded injectors if you plan on running some decent boost, fuel management, and gauges to moniter the activity

 

i am only looking to run around 6-8 PSI for the time being, as i don't want to have to build up my internals. I found out i can modify a HF Manifold to work, but it has to be ported to match my ZC motor, and custom work done to be able to mount the turbo. How much would this cost?

Also how much would my plumbing end up costing me?
