I was wondering if a 66mm throttle body is a good size for a turbo application. If it is, will it make a difference if i decide to non-turbo the car and use a aftermarket intake instead. I have a JDM Vti Engine in my 91 hatchie(D15B).The stock size for a D-series is 62 mm. Let me know what you think and thanx.

First off, as I stated in the other thread, your stock tb is NOT 62mm. You should measure the opening on the IM and see how big it is, and get a tb that is as close to that size as possible. While you're at it, measure the butterfly in your stock tb to find out the real size. Getting an upgraded tb, that is bigger than stock, and only running an intake; you're going to lose power. So if you upgrade it with a turbo, and decide to take the turbo off; replace the tb with your stock one for best results.
