Turbo'ing my 2002 civic ex

[thermal]

First off, which turbo kit are you planning on getting. Having a 7th gen civic, you really dont have so many options. The HP gain and torque that you have calculated is achievable depending on your set-up: fuel management (tuned) being the most important that will go along with the turbo size. However I doubt that you will gain that much power without a high flow exhaust system. That 3 inch" system may get you close.

As far as the boost controller, will never go back to manual after using both the GReddy profec-B spec1 and profec-B spec2. It is more expensive but it does make a difference. I think any electronic boost controller is better than any manual. A manual boost controller relies on spring tension (and its setting) to control boost, therefore will gradually open the wastegate as the compressor signal overcomes the spring tension. On electronic boost controllers, the head unit receives the signal from compressor and waits until the demanded set point is reached, then will send the signal for the solenoid/pump to open the wastegate in one full signal vice gradual (like what manual boost controllers do). This reduces lag.
