just put a vacume hose from that niple to the shiny gold thing on the other side of the turbo.

you want it to run from the nipple to the waste gate actuator, this should give you 6 psi.

not having the wastegate connected will give you the max boost the turbo can give. and probly blow it.

The factorty actuator is only 4psi...
by the time you factor in all the losses (restrictions) you'll probably only get 2psi if your lucky..


What do you mean?

Oops!! sorry didnt see that u connected the wastegate actuator up to the manifold... I thought you had it hooked upto the turbine housing :oops:

But yes the factory actuator is only 4psi

I used to have it running off a nipple on the intake manifold, now it is coming off the nipple on the turbo. Is this the right way to do it? How is it done in the XR6T?

On the xr6t's it goes from the nipple on the turbo to the boost control soliniod then to the actuator.

thats correct.

from the turbo to the control solonoid then off to the wastegate actuator.


even with a 4 psi actuator you will make 5 psi. best bet is to get a bleed valve to control the boost level till u get a proper electronic controler.

using a bleed valve is a nice smooth way of holding boost as it slowly opens the wastegate as boost rises not slamming open the gate when boost is achived causing spike.



just a nother note, dont make your exhaust too big, too much flow will cause boost control problems as the stock turbos wastegate is too small.

Hey,

Was surfing for info' last nite and found an article on Autospeed for boost control, and no electronics required, looked ok. Unless you want a high and low setting then an EBC is the way to go.

http://autospeed.com/cms/article.html?&A=0670
http://autospeed.com/cms/A_0685/article.html

Was good reading.

Cheers

Well, its running! We tried the T map sensor, and it spluttered as wasn't too happy. So, we changed it back, fired up. Had problems with the oil return line, the friendly exhaust guys fixed that for us.

So, it's running on the NA MAP and ECU. Capa custom tune in the near future, bigger exhaust, boost controller (we only hit 4psi).

Also, we unbolted the steering column from the spline, and now can't get it back with the steering wheel and the wheels both in the right spot. Does anyone have a good way to get this right?

I'll get some photos up soon.
