I have no choice now, I knew the RB26 was getting tired but she droped a valve today when giving her some:( spewing; I guess the build will deffs speed up now.
I all ready had the 25 head from a 33 s1 and I bought a rb30 whole motor for $100...go ebay:P I want to run the std manifold due to SAPOL giving me a nice defect label if I dont run factory manifolds.
I dont want to run because the 30/25 has more tourque, and less strain overall on the motor. aiming for 280-300 at the wheels on safe tune, and very safe boost as it is my only car.
Hey to all, I am new on here and fairly new to the rb motors; I am starting to build my 30/25, and I was wondering how much power can the std rb25 exhaust maifold flow? I wil be running a gt3540 turbo, and a haltec ecu.
Any input will be great
