I have been thinking that I want to upgrade my turbo. I am currently running a BNR stage 1 which is a stock turbo with To4b wheel and clipped turbine. The Rtek 2.0 has worked great with this turbo and after pulling some timing from the high load area there is still room with fuel. I'm running 4x720's.


I was thinking of trying out a to4e 57trim with a .84 A/R. Its on the small side but I want to keep some response and I'm only looking for around 350 horsepower at the most. If anything I can upgrade the secondaries to 890's if I need more fuel.


I wanted to see soome thoughts on this and hopefully there are some people with some experience running a full turbo upgrade with the RTEK 2.0


I'm making 295 horse to the wheels now with the hybrid.


Edit: The engine is on stock ports.

 

the default map is crazy advanced on max load.. im planning on upgrading to bnr stage 3 after the new revision to 2.0 comes out, so i can control the timing better

what injector d/c are you getting on that turbo with 720's at full boost?

 

Just a quick look at different logs the highest I could find was injector D/C 50.02 and that was at 11.0 psi.
