We get the k20a2/ k20z1/k20z3 here... but i am picking up a jdm k20a complete swap- identical motor as you have. I am looking to set the redline to 8800-9000 depending where it stops making power. After calculating the blower rpm at redline- i figure at max, 9000rpm redline, with a 3in blower pulley I'll be right at 17300rpm at the blower- which is about 3-400 rpm below what the blower porter recommends as max safe working rpm. Im not taking any chances this time around after the blower blew up the first time lol

only problem with the higher compression is needs good fuel and dont like loads of boost.. i only fuel up with 99 octane fuel as lower grade will knock.. ill have to see whats it like at 10psi might be the limit dont want the motor going bang..

lower k20a2 is better for boost
