Where To Take Car To Fix Boost Leak?

Think my car has either a boost/vacuum leak or a dodgy gasket. Sometimes when in the high rpms I get a loud high pitch whistle. My car also does not hold boost past about 4,500rpm. Holds fine until that point. This sound does not always occur, and occurs a lot less since turning boost down from 10psi to the standard 7psi.

My friend's step dad is a nissan mechanic, got him to have a look at it but he couldn't find the problem. He was just checking it out at his home, so didn't really have access to a lot of tools etc.

I wanna get the problem sorted out but not 100% sure where to take my car. The sound only occurs when boosting, so I'd preferably want to take it to a place locally that has a dyno so they can replicate the sound to help find where it is coming from. This is mainly to save myself the potential hundreds of dollars in time it could take a mechanic without a dyno to explore and eliminate the possible problem areas.

Can anyone suggest someone preferrably on the southside of Bris? Thanks.

hey mate take it to either of these places

- Mark - Godzilla motorsports Tingalpa ( great guy knows inside out about RB's)

- John - Brisbane Tunning and Turbo ( Good knowledge and cheap)

- Matt - Pits performance down the coast ( Awsome bit expensive)

expect to pay anywhere from 100-160 per hour dyno just to find the problem prolly another 150ish to solve it etc..

Do you still have the standard ECU in? 4500 is the point on R33 GTS-Ts where the dual stage boost gets ready to kick it into the second stage and if the boost is higher than normal or if it's already running 7psi at the lower rev range through the factory solenoid it freaks out and tries to cut the boost a bit. If this is the case you can fix it by bypassing the solenoid.

The standard solenoid is already bypassed - got a manual boost controller (turbotech).

This arvo's not too good for me. I've got to go to my girlfriend's dancing concert. Can do any time tomorrow though.

I've just got my car back from ABS, they've installed a Jim Berry clutch. Clutch is great. Apparently a piece of my old pressure plate had broken off haha. I've got a new problem now, my intercooler piping is hitting my fan, this was not happening this morning when I dropped it off at ABS :) ... sad panda. Hopefully be able to sort that one out this arvo.

Can help you carry the engine tomorrow :rofl: if that helps lol. If you fix my problem with the boost leak there's a carton in it for you or something of similar value!

its hitting the fan as the engine was shifted when they pulled the box out and they didnt put it back.

i can fix the piping issue. if u come to the bowling night tomorrow with the other sau members ill spend 5mins on it. and in that time i might be able to diagnose the boost leak.

my engine is out. prob keep it in the bottom garage

just let me knw so i knw if i need to bring tools :)

The piping issue is fixed for now. Had a play around with it yesterday afternoon. I think the engine may have just needed to be driven for a bit to get back into position..?

Can't make bowling tonight - got a mates 22nd bday celebrations on in the city. Haha, we're both pretty busy. I'm free Sunday though. I can hear a pretty loud sucking/hissing type noise from the front end of my intake plenum, around there, but can't pin point where it's coming from.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
