Were you in Melbourne Angelo? I have about a dozen wastegate springs laying around for Tial/Turbosmart gates, I even had some heavy springs custom made when Turbosmart refused to come to the party with a decent seat pressure.

Otherwise, just ring Turbosmart. They got mine to me pretty quick. Just remember the springs will soften over a few heat cycles, and the psi rating was nowhere near what I needed. (Higher manifold pressure will blow the gate open earlier.)

The other option is to use the top port to hold the gate shut, using a 4 or 5 port MAC valve, should help hold the boost flat with what you have now.

do they actually soften with a few heat cycles? I just put a new wastegate and spring in mine. supposedly 1Bar spring in an aftermarket actuator (internally gated). It worked around 12.5psi when I first used it yesterday, now its about 11 psi. I loved the extra response it gave but now I can't keep the damn thing shut

Edited by Blackkers

If it is internally gated, the spring is far enough away from the heat I would think.

I am running all 3 Turbosmart springs, and the heaviest they will sell for the new 45mm compact gate. It was apparently good for 26psi, it only ever held 24psi for the tune. Since then it has dropped to 19psi on gate pressure so I needed to run boost to the top port.

I had quite the argument with Turbosmart over it, as I wanted to run 30psi off the gate originally, they said their gates aren't up to the task of running that much seat pressure, and they couldn't make me stiffer springs.

My suggestion to anyone about to buy a new gate is to run the 44mm Tial with water cooling. Tial gates hold 4 springs as a bonus, not sure what the maximum pressure is though.

can you explain a little more on the second option !

the second option is for external gate, your turbosmart actuator is a IWG75? they take same springs as 38 ultragate etc

turbosmart does a range of high psi gates now, come standard at 35 & 40 psi

Really? Perhaps my whinging paid off. :P

    • 9" wheels are a little too wide for a RWD 32. They can fit. People have put R33 GTR wheels on 32s for years and years. But they are a very tight squeeze. This has been known for about 30 years. As I said - there is no difference between a 17 and an 18 in terms of what will fit. The rolling diameter needs to stay about the same as stock - not very much larger. If you increase that, you will start to have problems. If you increae rolling diamater at the same time as yo increase width, you will have problems earlier. as 9" wheels are pushing the boundaries already, you would need to be careful with tyre choice. I would put 8.5s on the front of mine, but would expect problems with 9s.

    • Diagnostic flow for a code 21 says check signal at the ECU pins, on a voltmeter of some kind it should read 0.1V at idle, 0.12V cranking, 0.15-0.25V at 2000 rpm. Check each coil such that +1, -3 is infinite or very high resistance, -3, +2 should do the same. (-1, +3), (+3, -2), (+1, -2), and (-1, +2) should all be somewhere between 0 ohms and high resistance. If you trace the path from the coil pin all the way back to the ECU in the diagram the resistance you measure at the coil vs connected to the harness should be pretty much the same. 
    • I have an elite 2500 running an adapter harness on an rb25de neo r34. I took the butterfly out and removed all that junk. But I also went Plus+t at the same time. The butterfly thing works in reverse to the boost solenoid on the Gtt if that makes sense
    • yeh they are 235/45/17 up front and 255/40/17 in the rears. I still didn't get my answer if i can fit a 18x9 up front. I want to get 4 of this and see if they will fit before committing as they didn't see an 18x8 as an option but there is a 18x9.5 also.   Enkei RS05-RR 18x9 35mm ET 5x114.3 75.0 Bore Matte Gunmetal Wheel
