Still in "safe" mode (boost below 2 bar) Very Happy.

..and still GT3071..? Any decisions for new turbo set up? Something big and ugly.. Twisted Evil Try some Holset or Schwitzer.. Razz Those turbos are really "bang for the buck".. Very Happy

Yeah, still "old" nice GT3071r Smile. Still not decided, I like the response of 3071, with it the engine have boost very soon (0,1 bar at 1800 rpm) and wide power range (from 3500 to 7500 rpm), which is great for a DD car. Going with much bigger turbo I'll loose DD ability I'm afraid.

Well Holset HX35 with 54mm or 56mm compressor and #12 divided turbine housing could be a nice step in terms of DD. Holsets usually beats any turbo in spool times in same turbo size category..

Pulls really nicely, how much was max boost in that video? Do you still limit the boost or let it rise to max boost when its possible? Razz

Thanks Smile. Yes, boost limit is active, especially in first two gears. Max. boost is 1,9 bar at around 7k rpm.

Will see.. it's never too late for a turbo upgrade Very Happy.

Garret GT3076R or something from GT35R family would do fine.. Very Happy

The GT3076R is too small step up (capable around 50HP more than GT3071R), but GT35R sounds much better Very Happy. Still, it will be very hard decision to move on because I really like this abbility of a GT3071R:
