Hi Guys,
I am in the process of putting together my first Rb30det, and have spent hours reading the threads. I would like to here some of your thoughts on the setup I am planing to run.
Currently I have a
- r32 Rb25DE Head, which has been cleaned up, new valve stem seals, and equivalent GTR valve springs.
- 2x RB30 Blocks
- ACL rebuild kit (cast pistons over-sized, rings, bearings ect)
- All new gaskets
- Rb26 Oil pump
- Crank collar
Support mods include
- Rb25 GCG High-flow 14psi actuator (min psi it can run)
- Sard 650cc injectors
- Splitfires
- FMIC, 3" turbo back (no cat)
- z32
- Sard FPR
Drive train
- RB25 Box with 5 puck button Exceedy.
Tuned Via Nisstune ECU.
I am doing this on a budget, and can do alot of the work myself, I have all the support mods from my current RB20 set up (hence the RB25DE head). But I have heard the NA heads have bad flow and can be restrictive.
This engine will be used for hill climbs and drift, mostly drift, so I want a reliable motor.
Concerns:
- My power goal would be around the 250rwkw (please let me no if you think this is un-achievable), and would love 700nm + torque.
- Could my goals be achieved on a standard Rb30 bottom end? Or should I rebuild it with my cast pistons and new bearings?
- Also for my goal and intended use, is standard pistons ok? Or should I really consider forged?
- The small RB25 high flow turbo could also see as a restriction, choking up the exhaust side. Or power-band could be peaky to early, maybe unusable? Thoughts?
If you have any other thoughts or suggestions on my planed build please let me no your thoughts.
