White_33

I recently had a Nistune ECU (w/ Z32) tuned on my R33 S2. Mods are minor: 3" TB exhaust, FMIC and r32 actuator (11psi). From drive in to drive out I gained a measly 10kw atw. Does this sound about right to anyone who has similar mods? I'm not concerned with the overall power output as I understand every engine is different, but I thought the gain would've been closer to 20kw. Would it be worth chasing another tuner to look at it again or hope that Toshi comes down to Melbourne to have a look?

Removed the actuator off your R32 turbo and put it on the R33 turbo -> instant 10psi.

The wastegate arm is on a 45 o angle on the LHS which is as far as it goes. I've tried pulling up the actuator arm but it's not budging more than 2 or 3mm anyway so I don't think the whole arm would come off just by itself in day to day traffic. Will put on the replacement clips when they arrive but thanks to all for the info.

Thanks, just purchased a couple of clips on ebay as I'm bound to lose another one sooner or later... For anyone else who needs one: http://www.ebay.com.au/itm/181079578338?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

When swapping the actuator off my R33 yesterday, I popped off the c clip that hold the actuator arm in place and I bloody lost it!! I know I'm a d!ck..... Is this an issue/do I need it? When I put the other actuator on and bolted it in place, it didn't seem like the actuator arm could come off by itself anyway. Any advice/info? Cheers,

Alternator issues?

*sigh* Yep, as mentioned above it is another R33 actuator as it has the elbow on it. Thanks for everyones help and for the pics Not a Pulsar, great reference I'll use from here on lol.

Thanks KiwiRS4T and GTSBoy, you've given me a greater understanding of how it all works now. Seems like it's all pointing to me getting yet another R33 actuator rather than a R32. Just seems strange though as I saw it come off the turbo and It still had the pin on it which had to be removed to fit on my turbo. Would the diameter of the hose going from actuator to I/C pipping have any effect on the amount of boost it would let through? (Mine was a super tight fit). Cheers,

Isn't that basically a manual boost controller though?

I was referring to the R33 actuator. If it was off an R33, doesn't the solenoind control the boost level so bypassing it would cause unliimted/freeboosting? Hmmm not sure how it could be installed incorrectly -> removed old actuator, connected other one. Is there any way the spring could be stuck causing it not to boost more than 7psi? If so any way to loosen it? Will have a look 2nite to find out if it has the steel bend on it. Thanks for all the info and replies.

OK, tried blocking the BOV vac line and ran another from I/C nipple to actuator but still only hitting 7psi!! Dunno where to go from here. If it was an R33 actuator, shouldn't it be free boosting if I'm bypassing the solenoid altogether?? Were R32 gtst actuators ever rated at 7psi instead of 10psi? Maybe the series 1? If anyone can shed some light it would be much appreciated. Cheers,

Cheers for the followup, will be doing this 2mrw and let u know how it goes. I just don't understand why it isn't boosting more than 7psi even if I am running through the solenoid. If anything I thought it'd hit around 10-12psi.....

I've got 2 lines running into the solenoid, 1 from the BOV (top solenoid) and 1 from the intercooler pipping (bottom). So I go straight from the I/C pipping into the R32 actuator and am left with the BOV pipping still connected. On a side note I just swapped over the actuator with another R32 actuator and it's still only hitting 7psi. I'll try running from the I/C -> actuator and blocking off the other line.

S1 or S2 R33?

Will get it replaced, thanks for your help.

I'm after some advice if anyone can point me in the right direction please. I was running a MBC but was pulled over by the popo so $352 later I'm going down the route of an R32 actuator on my R33. I managed to find one from a reputable source, installed it (still via the solenoid) but it won't boost past 7psi. The solenoid is grounded so I thought it should be hitting more than that. I had a look on this forum and found some other posts describing the install process, basically running a tube from intercooler pipping straight to the actuator but I'm concerned it will overboost and do some possible damage. The only thing I did try was to run from the IC pipping to the actuator but I also kept the BOV connected to the solenoid but that made no difference. Even if I'm running through the solenoid, shouldn't it be boosting more that 7psi? Did I get a R33 actuator instead of a R32? Thanks.
