Here's the setup, 96 Teg GSR boosted with a Greddy Turbo kit TD05 stock motor with intercooler and FMU 310cc injectors.

Here's the question. how much boost can safely be ran on stock internals with an 18g TD05 turbo. The turbo is preset at 8.5 PSI.

 

your about maxed out with that set-up. Switch to something a little better (hondata etc) you could run closer to 12psi or so.
It's all in tuning.

 

Yeah i wouldn't go any higher than 8.5 i personally would run 7-8psi on a gsr until standalone/tuning.
