Hi 97r33gtst-typeM,

When you dyno'ed, were you running at stock boost or above? This may make an impact on differences in output.

Like I've said before, I havent figures to compare before and after new cooler, but I could definately tell the difference (Im not just talking about the greater induction noise; with the 34'cooler in, it is feeling stronger). Like you said its not 20kw stronger like a FMIC - this goes without saying, but seeing that I could feel a significant difference I would say we must be talking about a 5% improvement at least.

That would be about the 8-10rwkw area which kinda sounds like the improvement sdm33 got. This may be felt more so with boost levels above stock where the lower volume and efficiency(?) of the stock cooler being less able to support higher boost and power levels. From what Ive read, the 34's cooler has 50% more volume than the 33's and is more efficient(how much more Im not sure).

      Took a little trip  went to nismo hoping the get my fuel tank hoses and unfortunately they told me they didn’t have stock luckily I was able to go to a Nissan parts store and they were able to order them in for me  then can home and cleaned the tank with some degreaser and fitted the new hoses before putting it back in the car

      100% I’ll hack into the 33. Strap a turbo onto the RB25DE and/or put the 25 head on a 30 block. 33 passed in cos the reserve was too high. I’ll try lowballing it again and negotiate. Aim is to have it landed and on the road for under 15k, then spend the same amount on top in mods.

      It's generally best practise to run 1x run without VCT enabled, then 1x run enabled till redline. Overlay the two torque graphs and you'll find the desired RPM to turn off VCT. Sometimes, it might be even worthwhile turning off VCT earlier control torque/cylinder pressure and using VCT purely to spool the turbo.

      First time I ever have issues with Amazon, but my wife often tells me to keep an eye out for fakes. It finally got me. I wrapped up the conversation with Gates. The gentlemen I was talking to seemed to hate his job but the response time on their technical support is outstanding. He stated that the hose is marked with some variation of "SAE J30R10" but that if you only purchase a 1 foot length like I did, it is possible to get a cut between markings and have a blank hose. To no ones surprise, he stated the swelling and "gummyness" isn't normal and to replace/buy from somewhere else (He mentioned NAPA). I'll toss a small end of the new one in gas for a few days before pulling the hanger out again, just to be safe.  Hose should arrive Monday. For those running multiple pump in tank hangers, you know the joys of getting them out and back in. I'm surprised I haven't destroyed my level float yet.  Lastly once I wrap all of this up, I'm planning on hitting the dyno again in 2 weeks while I'm on vacation. I realized recently that my VCT is set to turn off at 5000RPM. I'm surprised it wasn't increased while I was on the dyno last. I'm expecting I can increase it to ~6500RPM, if not more. Should hopefully get another 15-20kw out of it. I also want him to revisit my knock thresholds. I'm occasionally getting false knock around 3000rpm.
