if my kouki only had 42k miles i would most likely fuck spending 5 grand on a nice swap and spend 4 grand on a nice kat project… but if your not happy with the ka i would go rb26 with rb25 tranny… but thats a wack of money…
if your looking for speed and power i would go kat, but if you want a swap to be like everyone else or have that “stand out 240” save and go rb26:p haha i donno it all depends on what your looking for out of your motor…
think about it this way, if you only spend 4 grand going ka-t… you would have approx 1.5 to 2grand left for other things, suspension, brakes etc
