It does look like a small actuator ill prob have to buy a bigger 1 u think??

Yeah, well, you see those small can actuators were giving troubles to the owners - wouldn't hold boost, etc. Large can actuator is only available in 18 psi spec, but is better in keeping WG flapper shut.

Added: You should possibly do a lil bit of search about "big can", one of the results of that search would be this thread

i dunno but my guess is still on the AVO .73 housing..possibly being sold under a diffferent name..

As far as i know it is the only GT30 housing available that bolts up to the skyline dump pattern

That is the mtq sonic performance housing. Even they dont know what size it is.. They say .75 in one place and .76 in another on the same page..

I fear this will be another AVO job, and it probably comes from the same supplier.

Look here:

http://www.sonicperformance.com.au/739548_dash_RB20_dash_25/Nissan-RB20_or_25-Ball-Bearing-Upgrade/pd.php

803712-5001 is turbo part#,

112101-11 is the serial#,

That actuator is a Garrett number and is a GT28 1bar actuator (14.7psi), also looks like its missing a locking nut for the rod end.

Housings definately not garrett. Have had customers come back to me with stories of those type of housings being too small and causing boost creep, so we swapped them for garrett 771300-10 housings 0.82 int. gated 5 bolt outlet (same as XR6s) and that solved the issue. But obviously would of needed to mod dump pipe with matching flange to suit lol. Does look like an AVO housing but can't confirm, have you had a look on the inner edge of the housing inlet? the a/r size is sometimes stamped there. On garrett units they are.

just looked all over it and there is no numbers unfortunately :ermm:

so why dont these housings flow if they are supposedly bigger than the .63 but smaller than the .82 in theory wouldnt that be a good happy medium between power and response?????

Im lost :wacko:

basically because they were never really designed to have garretts 60mm turbine wheel stuffed in them, they have been modified to suit..

So while it does work it is not ideal...

what you stressing about anyway just put it on and enjoy, you can always change it later on down the track, hell i may even buy the housing off you if the price is right...lol

ARTZ why buy his housing when you already own the ultimate turbo :P HG has put 3576 cores in stock 2iu housings, how many times must I tell you the 2iu isn't even half your problem.

As for the avo or sonic comment, I think I pretty well covered that it looks the same and possibly could be from the same factory but rebranded (avo's rights must have expired and China found new places to sell its products)

The problem is exactly as said above, they are actually made for the stock turbo. They are ok when using a gt28 core or similar but the gt30 60mm is probably a little too big for their design.. Ive touched on it already, id probably prefer a 2iu or op6.

Ask mtq to swap it for the Garrett .82 and pay the difference if u have to, its still new.

Whats a garrett housing worth? and the labour costs involved in changing the housings?

garrett housings about 400-600$ and its only a few bolts you should be able to change it yourself if you can use a spanner..but you will also need a new dump, not sure how much they are..

GTScotT is right I dont want it, I have Kando power now..lol.. Dont worry just put it on your car and see how it goes, it will be great..chances are you will have other bigger problems than the housing anyway...just get it working first

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
