yea i give u props for tuneing a KA but the the fact is they r really hard to get good power out of them the best i have seen in 449whp with turbo. I prefer SRs because they r the orginal heart of a silvia, and have hella good balance and power output. plus u can tune them to be drag, race, drift. its a good all around engin. but anywayz so who will be showing up for sure. based on that i am gonna get snacks.
