So I'm trying to come up with a list of what I'll need. I'm creating an excel to just input the items, what I've bought, what I need to find, and their prices.
Goals: just around 250 whp. Stock h23a1. with around 140k miles.
Here's what I have so far, keep in mind it's all on stock internals:
F1 stage 2 clutch, 11lb flywheel-bought
RC 440cc or 550cc injectors - missing
TiAL 38 mm wastegate-missing
Walbro 255lph fuel pump-missing
BOV -TBD
Turbo charger- attached is the one I want, but it's subject to change. any thoughts?

IC&Piping by go-autoworks.com - missing
Downpipe go-autoworks.com -missing
Dumptube (Suggestions?) -missing
Oil Feed Line fast-turbos.com - missing
Log manifold (suggestions?) - missing
Anything else I'm missing? I heard of a catch can but I'm not sure exactly what that is. Or it's purpose.
Any input is appreciated.
