Ooh bit of thread necromancy FTW today methinks... Why this isn't slathered across the sticky bit at the top I don't know, because if folk want to tune their DT and not try to learn about turbos then they may as well just keep a stock of K14's and keep running 30psi through to 5k till the turbine pops... (Hint-: with a big Xantia FMIC and cool-ish air intake, the stock K14 will shit it's guts out the downpipe after approximately 2.5 pulls at 25-27psi not even going over 4500rpm!)
I've looked briefly over compressor maps years ago when I had my Supra but never really took the time to understand the meaning of them since the standard CT26 could comfortably run 14psi and that meant about 340bhp which was fine by me at the time... Now though, having oversped one royally and had a nice little warning (the type without oil ingestion and broken rods), it's definitely time to look into the whys and wherefores of turbos...
Currently thinking a GT2052V is going to be the answer, I could've guessed from other big power projects but having looked, it's probably the closest to not whizzing it's guts out while still making decent numbers & it should be versatile being a VNT too. (currently going for more top end power than torque as it's a completely stock engine, but the map suggests it should be able to make good low end torque if needed too).
Sorry, rambled on long enough now but at least this thread is back at the top again...
