Only 5psi, And Hosed Direct To Actuator

[ClutchBurndout-:(]

hi guys, first things first, i have a psi guage, actualy in psi, and its the second one ive tried, and they both say psi.

now

my solonoid is out of the question, nothing runs to it at all nor is it plugged in, and i have the hose running straight to the actuator, im only getting 5 psi, i thought it might have been a leak in the system, but its a solid 5psi and dosent budge up or down when full throttling, if there was a leak the boost would drop slowly? or something

anyway, any ideas?

cheers

Standard turbo?

If so then yes, about 5psi is all you will get running straight off the actuator.

yea standard, i thought the actuator is 10 psi?

do i have to hook the solonoid back up to get 7-8psi?

r32 actuator is 10psi, rb25 uses the solenoid to go from 5psi below 4500rpm to 7psi above that

[Ultimategtr]

zebra is spot on.

[ClutchBurndout-:(]

alright so im gonna have to hook it back up and then, do the DIY for high boost all the time correct?

Could just buy an rb20 r32 actuator?

getting a little hard to find these days, I Think I have one in storage lol

i dont really want to run 10psi, im not into the whole "must go faster" thing anymore, just would like the standard boost! 10psi = screwy mixtures etc since i just have the standard ecu

5psi is standard boost for your car..

No you just have to reconnect the bleed line to the bov return pipe and play with the diameter of the restrictor until you get the desired boost - bigger diameter = more boost. If you have lost the restrictor you can just solder up that branch of the T and drill the hole progressively bigger till you get the desired result.

Get a $30 tap and set it to 0.7 bar (8psi) yourself like I did. Better than stock IMO, more torque down low (obviously) and spools a little sooner.

The turbotech one on ebay is the one I have, well documented on this forum as to how good they are.

if im not mistaken, the taps are quite unreliable, ive used them in the past and they cause boost creep issues...

to be clear

standard R33 GTST auto is 5psi

standard R33 GTST manual is 7psi

both have a boost scramble or "boost hi mode" which bleeds in another 2psi around 4500rpm from the standard solenoid

if you bypass the standard solenoid and do nothing else minimum boost for auto is 5psi and manual is 7psi

my car is manual and its 5psi, hosed to the actuator

[paulr33]

maybe your turbocharger failed and yours has been replaced with an auto turbocharger?

maybe your actuator has failed and your actuator has been replaced with an auto actuator?

maybe your car was auto and converted to manual?

unlikely but possible

[Munkyb0y]

just get a turbotech manual boost controller. they are very reliable. no creep. no dramas. set it once and forget it.

[lachlanw]

because this hasnt been covered a million times before

i vote any new topic with r33 and boost in it be rejected

[bubba]

+1 for the turbotech boost T, I used one for a couple of years before I got an EBC, no dramas.

You want the TurboTECH item, not a TurboSMART item.

is that set at 10 or 12psi? maybe that's the cause of my high boost
