How to increase Boost PSI.

[legacy319]

How do you increase the BOOST for Both of the Twin Turbos. Is it all electrically done from the ECU. or is there a manual setting.

Thanks for any HELP.

You definitely need to do some research. Just turning up the boost will make your car go boom.

Here's some stuff to look into:
-ECU Reflash
-Manual Boost Controller
-Larger/better intake

^^^ he is correct that you need to make sure you compensate for the extra air and heat

however to answer your question. You have to force an interrupt between the wastegate and boost supply to the wastegate for each turbo. This may be done electronically through solenoid manipulation or mechanically through manual valving. Are the turbos independant - consult the flow diagram for the engine. It will tell you.

The Legacy TT motor is really odd... You'd have better luck, and results, converting to a single turbo setup.

It is doable... I think the best route would be to see if you can get in contact with a JDM tuner, hopefully one who speaks english, or a pro tuning shop, like PDX tuning or B4R.

You can talk to anyone at www.clubsub.org.nz (http://www.clubsub.org.nz) or rexnet.co.nz for the single turbo conversion.

I would be very careful about turning up the boost on a TT motor - they are prone to eating themselves, and lunching the primary turbo.

A nice way to get a boost increase is to improve the downpipe on the 2ndary turbine IIRC.

I read somewhere that the primary turbo is ECU controlled you can only fidle with the secondary and for a stock turbo one of my friends in Jamaica blew his at 19 psi.
