Hey guys,

I Went ahead and bought a turbosmart manual boost controller today. I turned the boost knob all the way to negative and the gauge reads 10 PSI. However, the car runs like a piece of poo and I cant get it back down to stock 7 PSI. Any ideas on how to fix this? I don't want to revert back to the standard boost solenoid :(

Thanks,

Probably R&R at 10psi (rich and retard), as for not getting 7psi you might have the hoses on the wrong way

Not worried about the car running like poo at 10 PSI since it needs a tune, just want it back at 7 PSI :( hoses seem to be in the right order.

I don't understand. You buy a boost controller to increade boost, so you buy one to run factory boost? Or am i reading it all wrong..

Don't bother increasing the boost on a rb25 unless you are getting a tune. Just stick with the factory solenoid until you get it tuned etc.

I bought a boost controller so I can tune the car at higher boost down the road. Isn't it possible to run stock boost on an aftermarket boost controller?

Is this right? I was planning on upping my boost to about 10psi. If i do that i'm gonna need to get it tuned? Are the stock computers even tuneable or do you need to get nistune?

I new to all this stuff.

On a rb20 upping the boost a little would be fine but on a rb25 they are shit and all of them do it. At around the 10psi mark if that some cars are different it hits R&R as Moodles2 said. No point doing it on a 25 as they run like shit and id probally say it would make more power on stock boost, if you are going to increase the boost get a tune.

And no factory 33 ecus aren't tuneable.

I am running 10psi which at first was using my fantastic twin boost solenoids trick but have since got me an R32 actuator.

I think I hit R&R once but cleaned the AFM and have had no problems since.

RB25det with R34 smic, RB20 actuator, Stock Turbo, Stock ECU (I think) and 3" Cat back exhaust.

^^^Looks like you have it hooked up right^^^

Try running a hose from the cooler pipe to the actuator to get back to 7psi and put the boost T in your glovebox til you need it.

So there's no need to plug all the hoses back to the boost solenoid? If not i'll run a hose from the IC pipe to the wastegate and see how that goes.

I actually kept the first little hose coming from the cooler pipe as it has the restrictor in it (dunno if it matters too much) and using a straight connector, joined another hose to it which goes to the actuator. No Worries.

As long as you have the other little hose blocked off like it looks like you do, it should be all good. Actuator pressure only. :thumbsup:

Thanks for the help mate, joined up the two hoses as you instructed, put my T-piece in the glove-box and now it's back to scratch :D

I'll have a 34 in a few days which is what i was gonna do it to... so no point?

R34 can be Nistuned - read the nistune website and the threads on Nistune

R33 cannot - see above

S1 Stagea is a major problem if auto - ref to the Stagea section.

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      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.
