Thanks Fella’s to take this off topic and to elaborate a bit more. I have an rb25/30 going into a r32 GTST.. expected to make around 600-700hp. Would you? A) R34 GTT box B) CD00#? I’ve seen a few posts about the CD swap and sounds fairly involved with making it fit etc but if it’s worth the work then I’ll go that way -

Lower at the hubs. Funny I forgot to mention that part. Do this pull here I turned the camera off too soon but the graph shows a drop at the top and that was because the pipe from the turbo blew off. The tuner said we could’ve made possibly another 15 whp. He also added if I switched to ethanol we could up the boost some more as well. I was comfortable capping it at the most of 20 pounds. Turns out the turbo pipe just needed a new worm clamp. Got home replaced that then did a third gear pull from 3k to 7200 rpm and the power was great to the top. I just got an ecu mounting bracket from IEE that I need to try and get everything to fit well. It’s a PITA to get the harness and ecu fit properly behind that kick plate -
He means "as opposed to mechanical cable drive". Older cars (R32 for ex.) had cable drive. Later cars with essentially the same gearbox, ie R34 GT (NA RB25) used essentially the same box as the R32 GTSt, but instead of a cable drive, had an electronic speed sender plugged into the same hole in the box, running from the same little gear that would have run the cable. Some of the shittier later cars use a speed sender on the nose of the diff, or the ABS sensors. -
Lower than engine, or lower than it should at the hubs? Either way, that is a nice power figure and I'm not surprised you say it rips now. What stopped you from turning it up any more? Injectors? Or did it just stop responding to boost?

Got my 34 gtt tuned last week. Car made 362 wheel horsepower at 19 psi. Turbo was the ATR43SS. Only other upgrades were haltech 2000 series. 650cc injectors, walbro 250, fmic. Pro hub dyno reads 6% lower than actual figure according to my tuner. Car is a real ripper now. IMG_7261.mov
