Hi guys,

I dont know if anyone else has experienced a similar problem, but when i shift gears after the wastegate has opened, it wont close for a while again. Im using a turbo smart bleed valve, and it has a bit smaller fittings on the valve, would this be causing it or have i forgotten something? Any help would be appreciated!

I had the same problem with the turbosmart valve when i had it wound all the way down (to make standard boost) i found after i gave it a few clicks to the + positive it would close the gate properly. ive had a few funny problems with that valve, i ended up drilling out the tiny hole inside filling it and then re-drilling the hole diameter. it seems to be ok now, although i cant run anything less than 14psi.

Ive only wound it a few clicks but dont want to wind it much more. Fully closed it had 12psi... At the moment it spikes at around 13-4psi and drops off to 12-13 depends on the load. Will the spikes cause my exhaust wheel to fall off, or is it just long stints with 14+psi? Because if they are not too bad i'll just let it spike at 15 and run at 14..

Thanks!

well i was told that they do tend to break at anything more than 14psi. ive been running my standard turbo at 16psi for over a year now and havent had any probs, it spikes at 1.1bar - 1.2bar (i think thats about 17psi) and drops a little. i havent had it on the track yet, because im scared it may break...

so be careful at what u do set it at. i dunno if ive just been lucky or whether its ok to run that boost. i am however plannig to uprgade to an RB25 turbo soon.

Sounds like i aint th eonly one who can't run below 13psi? I am also running a single stage gated boost controller with in cabin switch and have the same problem... I put my new turbo in the other day and chucked the boost controller in, and like someone said earlier my wastegate stays open for friggen ages... i don't get it... like i'm talken it flutters for about 10+ secs if i want it to... but my maine problem is i wnat to run less boost but not sure what to do, whether its the boost controller or the way we are running them? I am going to go disconnect the boost controller and see what happens i think...

I had a 2 stage bleeder but it was a home made type jobbie with a restrictor. It turned out that I was spiking to around 17-17.5psi when I was running 14psi. The in car boost guage wasn't showing this up and I didn't notice it on the dyno however when I hooked up my Blitz SBC-iD that had a peak hold readout it would show that I was spiking that that level.

Removed the bleeder and slapped the solanoid in there and the car felt like it was slower.. But.. it wasn't spiking anymore only hitting 15psi and holding.

I'm running 16psi and have been for some time now with no problems.

Well i think i am going to just take out my turbosmart one... can someone please explain to me how a standard R32 turbo hooks up to the factory boost controller... as the turbo i have has a line off the compressor housing like and R32 aswell as the line on the wastegate actuator which normally i am told you connect to each other which is how i am running mine now with the boost controller t-pieced out of this, however with my stock R33 turbo there isn't a line off the compressor housing so the wastegate actuator so it hooks up different to the sotck boost controller as comapred to an R32.

The Standard R32 has a hose running from a nipple in front of the turbo air outlet to the wastegate actuator. You simply snip this hose and insert a T- piece then connect the bleeder to the T piece.

The R32 doesn't have the same 2 stage boost that the R33's have hence it doesn't require the solanoid that regulates the high and low 2 stage boost.

I think i have it... i got it down to about 10-11psi, by pluging up the nipple on the compressor housing then running the wastegate up to the nipple on the cooler piping and then the bottom line of the two lines on the OEM bc connects to the intake pipe where the BOV return line meets with the intake pipe.

I fixed the problem. I got rid of the spikes almost completley buy shortening the hose around 15-20cm. Its not possible to make it shorter now :). I also fixed the wastegate problem buy opening the bleed valve more. As i turned it more it didnt increase the boost but made the wastegate shut faster when i close the throttle. I have it on around 16clicks open and it sits perfectly on 14psi, doesnt go over, and holds there to the crappy rb20 turbo runs out of puff :D.

How do you know your wastegate stays open? If it stays open doesn't it mean you produce less boost?

My car idles high and when i clutch in and come to a stop the rev's don't drop for about 2-3 seconds.. it hangs at about 1500rpms before it drops to idle.. sometimes it jumps a little... is this a wastegate problem?

I don't have any boost mods.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
