  1. what exhast setup do you have?

    try a dyno run with the exhaust dropped

    it sounds like its a restriction and causing too much backpressure

    3inch dump into high Flow cat then splits into 2x2inch pipes into a little muffler then out the back.

    it had no cat first and was doing the same thing and i got told to put one in because it didn't have enough back pressure.

    it is a pain in the a$$

    Does it by any chance have overboost protection similar to blitz units where the duty cycle is dropped by a preset amount when x psi is reached?

    from you description of the response your gain is set very high as well which could also be contributing.

    could not say my tuner sets it up.

    their is also a r33 with the same turbo and same problem and he is using a blitz dsbc spec r

  2. Hi guys I have a R34 with a Trust TD05 18g turbo kit on it.

    The problem is that it isn’t holding boost above 12psi. when we try to put the boost up to 17psi the boost curve spikes at 17 then drops to 12 then up to 14 then back down to 12 and stays their. One of the guys form Trust Japan was over visiting Australia and he said to put a cat in and I will fix it. I did this Tuesday and is still the same but making less power.

    Has any one else had any experiences with this or has any ideas?

    thanks

  3. hi guys looking at getting a new turbo again. this time i am going for power but still without huge amounts lag. <_< just wanted to no if anyone has used a K5 660R turbo before on an rb25? things i want to no r, what is the response like, what power can you get out of them (rwkw) and you general opinion.

    thanx :O
