Greetings from Washington, D.C.

I've been a long time lurker but I figure I should start participating.

I'm currently building my Civic project car with the following:

* D16Z6 block overbored +1mm (from a 1992-1995 Civic EX/Si for non-Honda folks)
* 9:1 pistons
* D15B8 8-valve head (from 1992-1995 Civic CX)
* T28 turbo, planning on running 5-7 PSI of boost
* CX/VX transmission

Feel free to give me grief. I probably deserve it

Well, at least you've got the idea right about going with the taller geared transmission. Adding a turbo for economy makes sense if you gear it up.

With the low compression it'll run decent at cruising but it's going to be very slow getting up to speed = more throttle = more fuel consumption.

I'm hoping that with the turbo assist it can get up to speed more quickly and use less gas. Then it can cruise out of boost.
