**This is a WORK IN PROGRESS**
--->VISIT HERE<--- for a document about some of the general basics and not so basics of turbocharging (somewhat dated material but still very informative)
Specific to turbocharging the ZX2:
Required parts:
turbo
manifold
charge piping (usually custom, 2,2.25,2.5in common depending on turbo and desired effects)
downpipe piping (usualy custom, 2.5,3in common depending on turbo and desired effects)
tuning!, megasquirt, sct or sniper
wastegate, internal or external
maf, draw thru or blow thru (not required but recommended, cant run much if any boost on factory maf)
injectors, larger (not required but recommended, cant run much if any boost on factory injectors)
intercooler (not required but recommended)
blow off valve (not required but recommended)
and many various other parts and fittings required to modify subsystems to the desired level of the builder (pcv, vacuum lines and fittings, etc...)
Turbo:
T28s, T3s, T3/T4s common
Manifold:
SPA Cast Manifold
TopSpeed Manifolds
Custom
Turbo size must match manifold (T28 to T28, T3 to T3 and so on).
Charge Piping:
Choose size depending on turbo outlet and desired effect of boost. Smaller piping = potentially faster boosting, larger piping = potentially slower spooling. As with all in life everything has its balance and smaller piping will restrict your max HP yet potentially build boost quicker, larger piping will support massive HP goals but potentially build boost slower, however this is more dependent on the sizing of your turbo itself.
Downpipe Piping:
Match to your turbine housing. Generally 2.5 or 3in. Make it connect to your exhaust, or just be your exhaust.
Tuning:
MegaSquirt
SCT
Sniper
Wastegate:
Internal or external depending on your turbo.
MAF:
When using SCT or Sniper there are values for most ford MAFs that you can just wire up and start from there. When using SCT or Sniper MAF transfer function tuning is generally your first main focus.
With MegaSquirt you can run so many different systems you can choose to use the MAF and tune for it or run Speed Density.
Injectors:
When using SCT or Sniper there are values for most ford injectors that fit. Start with those and tune from there if necessary
MegaSquirt will run basically everything depending on how your setup. Read the manuals, alot.
Intercooler:
Recommended to cool the heated and compressed air exiting your compressor housing. Cooler denser air is better.
Blow Off Valve:
While not technically necessary is recommended to vent excess pressure in the charge piping when the throttle is shut. Can aid in prevention of compressor surge, protecting your turbo from damage. Makes the iconic "woosh" turbo sound when vented to atmosphere.
Various:
PCV system (PCV valve should not see boost), Vacuum lines (secure them, add and run as as necessary), Check Valve for brake booster.
