Hi all,
I'm new to this forum and I've been on CalaisTurbo and R31skylineclub forums for a while and have had RB30E and RB30ET setups on my R31's I owned. I have now recently purchased an R31 with an RB25DET NEO motor, RB20 box with Extreme racing button clutch, R31 silhouette 3.9 LSD, 3 inch turbo back exhaust, AM front mount cooler, and dual stage boost controller (8psi on low and 13 psi on high). Currently the power I'm getting is 187rwkw @ 8psi and 212kwrw @ 13 psi with the stock R34 GTt ECU, stock injectors and bosch 040 pump
with my current setup my questions are:
*What turbo does the RB25DET Neo have and how much boost can it be wound to?
*How much boost (safely) can I run on the stock internals of an RB25DET Neo with stock ECU & A/M ECU?
*What is the limit on the stock injectors (power/boost)?
*What is the best aftermarket injectors with my setup without changing the fuel rail?
*What is a good suggestion for an aftermarket ECU to run higher boost?
*How much power can my drive line possibly take (RB20 box/extreme racing clutch [rated at 1600 kg's..so I've been told by previous owner], and R31 silhouette 3.9 LSD)?
*I've heard of KKR turbo's being a decent/cheap upgrade; are they reliable and substantial in comparison to power output/price wise on other turbo types?
Sorry I'm still pretty noob with all this
What I'm basically after is a high power output....maybe somewhere between 250-300rwkw without having to change internals (if that's even possible) and most of the current setup; yet at the same time be on the safe side. Maybe looking towards upgrading ECU, injectors and Turbo, most likely ECU if anything.
The usage of this car is basically a mixture of street/drag/weekend use. Trying to keep costs at minimum (if that's even possible LOL) and to increase a power output on my setup safely. Any suggestions?
