Precision 6466 is big, I thought my gt35r was big on my sti. I put a little over 500 to the wheels with a 35r. That dart should fly if everything goes right.
A friend of mine put 908AWHP in his evo last summer with a 6466. They are a great turbo with minimal spool time. He was at full boost by 4300, so with a larger displacement engine I hope I can make full by 4-4100. Should make a fun launch with lots of useable top end!
