Hey guys fitted a turbosmart boost to my 32 this arvo.

Car has a Hypergear hiflowed 33 turbo on it but even with the tee turned all the way down the cars hit 17-18 psi no matter what ive tried it just boosts to what ever it feels like. Also after the install as soon as its around 10-13psi it whistles really badly which im guess in a leak somewhere????

Any help would be awesome thanks

The turbosmart controller uses a ball and spring gated system that can cause boost spikes, its designed to bring on boost faster for more response. It says in the instruction manual that you can remove the gate system for more direct boost control.

Unscrew the nipple on the side leading to the boost source (i.e. the nipple that DOESN'T go to the wastegate, and piss off that ball and spring thingo.

Did the trick for my mate who I installed one for...

Or bin it and get the turbotech boost controller of ebay for about $30.

I borrowed my mates turbo smart manual boost controller (an older desing) and that had cronic boost spike (up to 15psi then back to 10psi)

ive brought the turotech boost controller and it is awsome. doesn't spike at all since ive had it and is very easy to use and you dont have to wind it mush to see a diffrence about 1/4 turn for 1psi.

would sugest it mate.

rb20s are bad for cracking ex manifolds... check for turbos cracks and the mailfold

mmm first i've heard of a R32 cast manifold being a soft spot on a RB20...

Infact i cannot even recall a post on this forum about anyone ever breaking one!

im over 6ft tall and have dropped one onto concrete at a wreckers when I was picking it up for a mate, didnt phase it....i think it is still on the car that is making ~300rwkws..that was 3 or so years ago....and no cracks

      R34 GTR Speedo Drive , sensor type ?

      By Butters · Posted

      Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
