brought a r32 actuator and swap it with my existing one. went for a little squirt and i manage to only reach 7 pounds.

the only thing that i see is different is, it is 7 pounds even when it is below 4.5k rpm where it used to be 5 pounds then 7 pound after 4.5krpm.

any one have this problem? pretty much stuck at the moment

i have a er34 gtt

weird

sorry to hijack your thread but thats exactly what happens with my gt-t... does that mean its already got a r32 actuator thats not hooked on properly? :cheers:

how could i check to make sure which actuator i've got?

i don't have a boost controller.

i did a search and there a few ppl that has this problem. but doesn't really tell me how to fix the problem....

all i did was replace the 34 actuator with the r32 one so the hoses are in the same location..

how do i get rid of the stock solenoid ? pictures will help alot

with the exeption of the gtr, all r32 i'e gtst gts4 turbo cefiro and turbo laurel actuators are all set a 7 psi from factory, this is assuming it is directly connected to the turbo.

you will need to A bend the actuator arm

B (if you have a threaded rod) adjust the length of the rod

C install a boost controller

D pin hole the actuator housing

E change it to a aftermarket unit

F T piece the actuator hose(bleeding off the boost to the actuator taking longer to open the wastegate.

i put a R33 turbo and actuator on my r32, boosting 11-12 psi from my expeirence the 33 is a better option.

nah. r32 actuator is 10psi. r33 one is 7 psi.

i have em both and checked it out against pressure gauge.

i think what you need to do is get a boost/vac feed from the compressor housing (on r33 turbo you ll have to drill n tap a hole, meaning you ll have to take the housing off - too much hassle and you ll get less boost, i.e. your boost gauge will see less than 10psi due to pressure drop thru i/c etc) or get a feed off J pipe (would be easier and can crank up a lil more boost this way)

Edited by sonoramicommando

in my old 33 i ran a 32 actuator at 10psi. they straight swap into the 33 and the only thing i did was ground out my standard solenoid to have it run consistently at 10psi. if the solenoid was still connected ran 7 then 10 after 4.5k rpm.

in my 34 now i have the 32 actuator and same situation a the 33 i am running 10psi

What you actually want, is your pressure source from POST intercooler, how it is on an R32.

The R33 takes pressure pre intercooler.

Then you get a pressure drop when "cooling" it all down.

R32 go post intercooler, and you'll get a "cooled" 10PSi. What your boost guage is reading is a 10PSi charge that has been cooled, and hence, you're getting 3PSi...

My pressure source is straight off the manifold. Much better...

yes i have. is it that what is causing the issue?

The solenoid controls boost, is comes before the actuator. Replace it with a turbotech boost contoller off ebay (about $30).

Here's how to fit it:

i agree with you that you should get post intercooler, somewhere before throttle body (assuming turbo can handle a bit more than 10psi - most probably) but that's not how R32 actuator works.

it gets pressure feed off turbo compressor housing - i.e. pre-cooler.

just you gotta make sure turbo is not seeing too much boost and blow off its wheels if you are going way over stock 10psi.

im curious. why wouldnt getting a pressure feed straight off either compressor housing or j pipe work? i don't know if that affects the fuel/ignition side of it but the wastegate would progressively open to achieve 10psi (if using R32 actuator). it is independent of ECU or anything else that way - purely pneumatic the way it works.

I'll hook up the actuator bypassing the boost solenoid and i only see 5 pound. connected the boost solenoid to the actuator n i get 7. does that mean the r32 actuator is either broken/or not a r32 actuator? or something in my car that restricting the boost. cause when i compare my actuator to it the nipple you connect the hose to is a bit different

i have a front pipe,cat,cat back exhaust and a pod filter.

Standard R33 actuator is 5psi, not 7psi (don't know if same as R34)

Just that when you hit the 4.5k revs, the solenoid bleeds kicks in allowing the turbo to reach the 7psi, in the same way a bleeder works.

If you wre to install an R32 on an R33, you 'should' have a 10psi before 4.5k and 12psi after...

Make sense? (agian for 34 i'm not 100%)

So your R32 Actuator should see 10psi if no solenoid is invlolved.

Are you looking on an aftermarket guage using psi? or the standard guage that does Hoolymologenus'esssss thingos? (not psi)

aftermarket gauge. i have two(one built into my blitz turbo timer and a auto meter one)

hmmm r32 skylines the actuator's pressure feed comes from the housing just before the 3 bolt flange into the intercooler piping. the hose is around 150ml's long......this is pre-intercooler. not ideal in most situations.

because as soon as the turbo hits 10 psi it opens the actuator....giving you probably 7 or 8 psi at the throttle body once the air had travelled via the intercooler.

the ideal way would be to run a hose from the just before the manifold /plenum chamber i.e J pipe (idle control feed) down to the actuator. and plug the hose from the turbo housing.

this way the wastegate wont open till 10psi is reached at the manifold.

    • Doing a refresh of my 33 and can see a few websites stating they sell the entire main carpet for our cars, but they all have generic photos which is fine, i understand they are custom made to order.  Just seeing if anyone has got it done or had any experience with this, as i would only want to do it if the fit and finish was as good as oem https://carmatsdirect.com.au/products/moulded-carpet-or-vinyl-for-nissan-skyline-r33-1993-1998-coupe https://knoxautocarpets.com.au/moulded-carpets/nissan/skyline/skyline-r-33-1993-1998/
    • Any plans for E85? If so, add flex fuel sensor.   I'd probably add in the sensors I mentioned above if the Link will support using them for engine protection. With water pressure, you need to be able to effectively set it that "If temp > X, and pressure = atmospheric, shutdown" as at running temp, you should be able to read pressure in the cooling system. If pressure suddenly disappears, it means the water went some where, and this is a quicker reaction than waiting on water temp to go up (Which, can take a little longer than you'd like, considering it now has to wait for hot air to heat it up) Oil pressure, Oil temp, both would be on my list too if you're looking to add sensors. Wideband O2. And at least one EGT sensor. If you're feeling deluxe, put in individual runner EGTs. Single EGT sensor is more so forget about a specific number, get used to "What is normal EGTs", and then keep an eye on it, if it starts going away from "normal" it's a sign something is wrong (Also, things like the tune can still start going out of spec, but EGTs may not show it, for example one injector starts running leaning, so ECU richens everything up, now 5 out of 6 cylinders are rich, and running cool, with one cylinder lean and running hotter, so it's not perfect) Then there is your other things to look at non sensor related, but you may have already done, or have underway, and that would be things like building a sump for more oil, and better oil control under high G-Forces (Cornering, brakes, acceleration). Basically, the above is worth looking/thinking about, if the ECU can do protective stuff with it, and you continue to use it how you are (Drive it to the track, thrash it, drive home, repeat once every 3 to 4 months)
    • Can also confirm these work a treat for most balljoints and bushes. If you have access to a big rattle gun, they make the job so much easier and quicker, compared to using a socket wrench or shifter on the c-clamp 👍
    • Its sort of street but got used for circuit sprints on account of I never drive it on the road because I dont have the time to spare. So it usage was sits around for months at a time then gets driven either 50 or 250 kms to the track followed by 20 laps followed by 50 or 250kms home followed by stuck in the shed until next time. So yeah neither fish nor fowl. Just dont want to break it on the track as a preference. Hence the fairly short sensor/mod list. Probably more worried about it pinging itself to destruction more so than anything oil related.
    • My thing I'd be doing, is pulling it out, and just getting the tune cleaned up for now. Before that even happens, checking over everything, like vac hoses, fuel hoses, etc. No point dropping thousands on sensors if the moment you start it back up all the oil leaks out, or it has massive vacuum leaks etc.   But really, to know what to do, depends on what your use case is. Hard core track car? Throw most sensors available at it. Street car, I'd probably just run oil pressure, oil temps, water pressure, water temp, probably fuel pressure too. I don't know exactly what the Link can handle and do with those though. And if it's mainly just to cruise the streets, rather than mountain runs, you can probably skip most of the above if you've already got them in as gauges and warning lights.   PS, inb4 "sell it and buy a modern sportscar"
