when you upgrade the turbo, do you absolutely need an electronic boost controller? how does this apply? like, i get that you use it to control the boost, but doesn't the tune do that for you? i know the boost controller is adjustable, so are you able to get an Ecutek tune (what i currently have) and use the boost controller so i can use a higher boost level when i feel like being spirited or at the track or something and then turn it down if i want to be a bit more economic with petrol? or will adjusting it ruin the tuning and potentially the car?
I'll mspaint you up a diagram or 3 after dinner to explain boost controllers
The EBC for dummies version (so my understanding) is that with the bigger turbo's and higher boost the stock 2 port boost controller will struggle to control the boost (through vacuum bleed manipulation), where a 3 port EBC will allow the tune greater control over the wastegate actuator and hence the boost level.
Some people put a "pill" into the vacuum line (welding rod normally), this has been known to be a bandaid fix for the 2 port. Or you can swap to manual boost controllers. I personally find that a 3 port EBC (like the grimmspeed) enables a greater control of boost, as well as a greater ability to delay when boost comes on, and taper boost off at higher RPM.
3 ways of controlling boost, doing something other than this could cause your boost to spike, and/or be uncontrollable :
EBC Set Ups (controlled by ECU/Tuning)
2-Port (stock set up):
Attachment 14124
3-Port (Interrupt):
Attachment 14125
Manual Boost controller: (Controlled by turning a dial on MBC)Attachment 14126

awesome thread, thanks tons for this info. helped lots
if i were to go buy a bnrS3 what would my shopping list need to be?
wouldnt need to go internals as well?
Yes internals as well
already have hpfp internals...im meaning forged pistons and so on
Some good info here on stock block limits. http://www.mazdaspeedforums.org/foru...d.php?t=187770
