thanks for the reply, 4-1 is a performance choice, i can't justify losing top end for low-mid end with my k24. already it makes wayy to much down low to control, i would rather have that power avail to me up top. secondly, looking at most of the k swaps/tuning company cars in Japan, seems like they all run 4-1's with their k24 packages for race reasons again, from what i have seen.

im really only putting this thread up to see what the "performance" differences between the 2 would be, there are many threads on this forum about the other differences.
