Hey man. Yeah all went perfect.

Just unlug and un-bolt the solenoid. Have the Actuator vac line running straight to the Intercooler pipe (where it is factory) and the line that comes of the intake pipe, either get a blank for it or put a bolt in it. Whallah!

Hey all, sorry to bring up an old thread but it seemed like the best place to ask for help.

I'm wanting to get an R32 actuator and stick it in my R33... question is, how do I actually replace the actuator?

Is it a simple matter of say, removing my intercooler piping and then I'll be able to get to it? Or is more work than that needed to expose what I need to get to?

You can get at it with the intercooler piping on.. at a pinch.

Take the circplip off the end of the rod that connects to the wastegate flapper, pull of the VAC line, then remove the two bolts holding the actuator to the turbo.

Reverse to put the R32 on :P But, only running a single vac line from the intercooler piping to the actuator. Blocking off the hose that went to the intake tube. And removing the boost solenoid.

I picked up the 32 actuator last weekend and popped it in, easy as pie. It was exactly as gotrice said... just circlip off, remove bolts and vacuum line... done!

I'm only hitting 9psi or so though... and that's reading from the stock spot on the back of the plenum.

Has anyone had that happen? I'm gonna hook up the solenoid again this weekend and see if I can get to about 12 or if it'll only get 10-11, so confused.

Does anyone have a picture of the stock R32 actuator available, and where it's located in the engine bay. Hope I don't appear too stupid, but is the actuator and solenoid two different things? or do people refer to the same thing by different names. I've read the thread about grounding the stock R33 solenoid wire too achieve a permanent high boost mode. Just wondering about the actuator side of things, especially this thread here. I like the idea of 10psi and am nearing all my stage 1 mods being completed.

Yep they are two different things :)

The solenoid:

The acutator:

Obviously the bit on the right :P

If it was me, id find an r32 actuator and ditch the solenoid all together :) Thats what i did.

Thank's for those :)

I'm weighing up a few things when it comes to upping the boost. But had another question.

Will installing a FMIC increase my boost pressure? I've read a few things where this might happen due to the increased airflow. Currently I have the stock SMIC installed.

I was aware of the "increased" lag when mounting a FMIC. Was curious as I have read folks also had more boost showing on their gauges after mounting a FMIC too.

My goal is to get the FMIC installed, then be running at 10psi. So am working out whether I should do the R32 actuator, or go with a t-piece. I quite like the R32 actuator idea though. Seems like a nice efficient way of getting to 10psi without splicing in t-pieces and so on. Also I'm more likely to eliminate boost creep due to having no t-piece setup right?

Will see if I can wrangle up a R32 actuator. As far as the solenoid goes, that only gets disconnected if I go with the R32 actuator right? otherwise I can ground it now to get 7psi I believe. That's where I read about the increased psi from installing a FMIC I think. Guys would ground the solenoid which should give 7psi, but in actuality they were getting 10psi due to the higher flow.

It works out pretty similar.

Grounding the wire will indeed give you 10 or so PSI if you have a turbo back exhaust etc, and so will the R32 actuator.

I just used it for cleanliness.

I guess it depends on the FMIC you choose. I didnt notice any change in throttle response personally.

I bought my FMIC a few months back but have been preoccupied with other facets of the car. Now that I'm close to finishing all of those, it's FMIC time. I have a return flow ARC one. I don't know the model, but it's more of a square shaped unit than say a stock GTR FMIC one which is not as high, but wider. I'm told it is a very good unit however as it's Japanese made and ARC is a good brand. It also looks to be in great condition.

I have a turbo back exhaust. 3" to the cat, and slightly larger from the cat back. So hmmm, what would you do in my position then rice? Would there be any difference in the way I get 10 psi? R32 actuator vs grounding solenoid?

And if I get 10psi through grounding the solenoid due to having a turbo back exhaust, wouldn't I then get more than 10 with the r32 actuator?

every cars different, you might get 9psi, you might get 11psi. at the end of the day it doesnt make much difference, try it without the solenoid plumbed in and if its not enough you can use the solenoid to give you a little more at higher rpms. if that isnt good enough buy a turbotech mbc.

dont do that. think, if the sloenoid takes the boost from 5psi (stock r33 actuator set level) to 7/8psi. add that to your 10 psi r32 actuator, and you are spiking to 12/13psi. unless you want to

sorry to hi jack, recently installed a rb20 actuator and now its overboosting to about 16+psi !. I've been reading and believe i hooked up everything correctly. I'm puzzled now :S. Current mods, 3'' bellmouth and zorst, turbotech boost T set to ~12psi and a nistune remap.

Prior to this problem I had another 1, my boost would drop from 12psi to about 10psi only in high revs (5500-redline), the actuator was suspected so i replaced with rb20 1 and now this :)

Any ideas guys?, only thing i changed during isntalltion was extending the vac line from actuator to boost T to cooler pipe to reach. :S

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
