Where's My Actuator Pipe?

I need to disconnect the actuator pipe to run open boost .. I dont have a boost controller yet so apparently this is a good way to see how the car will behave if I did have one installed..

Only thing that controls the boost at the moment is the wastegate spring.. can anyone point me to the right pipe / hose to disconnect to achieve this? Thanks in advance

engine bay pics are as follows:

Find the actuator and pull the vac hose off it? There is only one...

And is the car "stock"? AS it wont behave much at all once it hits boost cut, or the turbo explodes

Its got a few mods, and yeah ill be watching the boost like a hawk.. I dont produce full boost until around 4k, so this test could be interesting to try out

whats the actuator look like? hence why i posted the pics .. cheers

had me confused as hell here sorry, so basically since the external wastegate does what the actuator used to do I'd be right in saying yank that hose of that since the stock actuator / turbo setup is long gone

It will probably BLOW UP judging by the amount oil coming out of you rocker cover vapour hoses

yeah thanks for noticing but its not like I'm gonna be driving it around everywhere like this, I doubt ill go over 3k its just to see if the boost will build quicker since my lag is shocking

just took the hose off and went for a drive, made stuff all difference car is still laggy as hell.. was at about 14psi at 3800ish rpm .. so im highly doubting a new boost controller will make it any better.

I was really hoping to produce my 19 pounds (current spring setup) at a lot lower revs with this td05 but hey, im not really sure what to expect running open boost like that.

Yeah made a bad call. For some reason i overlooked the external :)

I suppose i should mention that its a knock off chinese td05, probably explains a few things.. Although from my experience this turbo produced more hp than a genuine mitsi turbo on my last dyno run @ same boost but they generally dont last as long.

ummm removing the VAC line to an actuator wont do anything (if you still had one)

You need to wire the gate/actuator shut if you want to test if the turbo gate is opening prematurely causing poor response (if you still had one)

And i say - "if you still had one" because fk me...

You have an EXTERNAL WASTEGATE - you do not have an actuator... The gate is the actuator.

So no idea what anyone in this thread has been talking about... look @ the fluro poofter pink thing in the pictures!!!

So... as before - removing the hose, same in this instance, isnt going to do a thing.

If you want to test the GATE spring being the cause, just take the gate off and put a blanking plate on it, you'll soon see if its gate creep causing the problem or not

And get rid of that silly filter thats blowing oil over your engine bay. I kid you not when i say this... that filter will give you a fire in your engine bay when it spits oil when things are hot. I've seen 3 cars catch fire because of those retarded filters that server no purpose other than getting an insurance payout for a burnout car.

Oh, btw - insurance wont payout because that's your own fault for a illegal, and dumb mod :(

wow thanks, kinda.. :thumbsup:

Just so were clear, this is New Zealand .. and its perfectly legal..

I didnt even install the filter thing, it magically appeared after mechanic installed the turbo, if its a stupid mod fine, but I just left it on cos i assumed it did something. Im not a mechanic!!, hence why I use this place to obtain answers, so enough with the flameing.. purple poofter thing??? come on, does it need to be black or something.

but thanks, for your insightful answer I do appreciate it..

btw - the oil all over the place is from a crack in one of those pipes, yes it needs replacing..

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
