Hi guys,

This may have been covered numerous times, but i remember reading it in a HPI magazine some time ago.

Please, don't give me grief, just answer the question. :)

So i'm thinking of putting a RB20det standard actuator on R34 Rb25det standard turbo on my R34.

Will this hold 10psi flat without spiking and how would i go about the boost solenoid? remover lines, straight bleed?

Thanks

the R32 actuator is rated at 12psi

so the minimum you can run, is, 12psi

it should be fine and is a good upgrade

no need for a boost controller or bleed valve etc

just actuator and away you go

If you want proper electronic boost control, the cheapest option is try the Gizzmo MS-IBC, overkill for what you want though it's pretty good for $300 (sometimes I see it down to $250)

What other input do you need?

It wont effect anything, it will just work and be good. No need to wire up boost controllers etc and set them up.

It is pretty much the limit boost wise you'd want to run anyway, without having to upgrade the ECU/AFM.

THIS was the very first mod i did on my RB25.

Holds boost at 10psi from around 3000rpm all the way to the redline.

10PSI . rock solid, not 12, not 10.1, not 9.9. 10psi.

as for the 2 stage boost solenoid.

cut the ground wire, strip 10mm off and ground it by screwing it under the solenoid mounting nut, done.

drop the bonnet and go for a quick drive.

make sure you put back any and all hoses that you undo. (you do not want to boost 2bar)

oh yea, for the r32 actuator vacuum hose, you're going to need something about 100mm longer.

less than $5.00 from any performance shop.

you'll love yourself for doing this mod, your tyres and petrol tank won't :D

have fun out there.

what mods do you have? fmic, full exhaust?

a lot of people report a slight boost increase (2-3psi) when fitting a free flowing exhaust and a front mount, without touching their actuator or installing a boost controller of any sort.

from memory my last dyno run with stock actuator/smic/dump i hit about 9psi :D

interested in how accurate the 32 actuator really is.

i have FMIC, trust cat back and hks pod.

i also have Power FC but it's not in yet because it's like $650 to tune.

I think, boost is creeping slightly atm 8-9 psi... but i thought it may have something to do with the .8 gap spark plugs...

But quite possible due to the upgrades.

I use my car a fair bit for drifting... and the power bug has really hit me :D

I'm hoping to whack the rb20 actuator on, run 12psi and make around 200rwkws (hopefully this will be enough to keep me slide happy)

I will keep you posted, but atleast i now know i need to ground the boost solenoid wire.

Couldn't i just rip the whole boost solenoid out and run a direct line from actuator to intercooler pipe?

Cheers guys

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.
