I dont care if this was posted in the past or a cut & paste. The point is it is a great guide for those unsure of what to do first before simply upgrading their turbo and potentially blowing their engine without the proper preparations.
I've found this useful and thankfully have already done most of the required upgrades previously. I've currently got a Dual Stage Blitz Electronic Boost Controller and mite sell mine for an Actuator so i cant possibly get defected for that.
Got everything required for Stage 1 - 2 (Blitz Intercooler, Full 3" exhaust without Cat, made a huge difference, Pod Filter, except for computer tune/ecu, Some Japanese Fuel pump system & Extensive Suspension work)
I think I will work on the head gasket next.
