hey guys, i should be upgrading my bottom end on my civic in a few weeks. it will be a 2.0 from a 1.8,B18. fully sleeved, 9:1 comp ratio, Je piston, crower rods.
now i want to upgrade my turbo to something a little more efficient, i see a lot of people using precision turbos, but i dont know which one would be the best for my application, right now i have just a normal T3/T4, and i am using RC440s, i would like to make as close to 400hp as possible, also my turbo manifold is for a T3.
so which ones could i use, i will not be revving over 8200.
I could only make 300whp safely on 440's. I made 325whp but the injector duty cycle was at 94%. That too high for me. Like john said an SC50 would be the turbo i would run. They are good up to 470hp. good luck with your project.
