ok i have a b16a2 in my 92 civic hb cx and i want more power. i was thinking b18 bottom end or b20. or b16 block sleeved. i want a turbo but i want it to be reliable too. i drive this car everyday so i cant afford to have it in the shop all the time. and if i swap the bottom end out what are the chances of the pistons hitting my valves or head at high rpms. and if thats an issue how high can i rev it b18 and b20 .. I NEED MORE POWER. and i just got a new credit card with a 4600 dollar limit no interest for a year.
