The main ones are the fuel pressure regulator, map sensor, boost controller/wastegate.
The oil injector lines go to a y piece then they go pre-turbo.
You also have the oil breather system but your better off ditching that and going for a catch tank.

Im at this stage also..

The oil injectors require plumbing into pre turbo?  You mean between the air filter and the turbo?

How about the purge control solenoid?

Cheers,

James

Yeah that\'s correct.

I ditched that too and left the chacoal canister to vent to atmosphere.

Also i\'ve forgotten that if you still have the double throttle you\'ll need that hooked up aswell. (although your better off spending the time to remove it now).

the double throttle is always open, so it can just be de piped, other than that same just junk the lot, if your going for an after market fpr get rid of the standard mazda item.

the double throttle butterflys are always open and only close when the solanoid allows vacume to the actuator, so you can just pull the pipe/ solanoid. have a look on my thread in the members rides section, i removed the butterflyes with extreem agresion ;)
