GSR motor (w/ ls rods and crank), which tranny?
A few questions about this motor:
1) With LS crank and rods, cams and cam gears, intake, header, exhaust, what kind of hp and torque numbers will I be looking at?
2) What tranny would be more suiting for the motor after all that is done to it?
3) Should this beat a stock type r motor (I cant decide on these two motors)

1) Expect performance similar to an LS/VTEC with those mods, with better reliability, of course.
2) If you're building it as an N/A application, the GSR tranny should be fine. If you want factory LSD and shorter gearing, you can go with a 4.40 R tranny. If you want even shorter gearing, you can go with a 4.785 R tranny.
3) Theoretically, this setup should be stronger than a stock B18C5/R. If you figure 15% drivetrain loss, the 200hp JDM B18C-R puts out around 170whp, whereas the setup above puts out closer to 180whp. Of course all engines are different and some run stronger than others fromt he factory. Tuning is also a factor.
