Will a D15B VTEC long block just drop into a eg hatch that has the d15b7 in it? Will the ac components hook up and everything? How would gas mileage be? Thanks

drop in yes, although youll need a vtec ecu to run it. mpg will depend on driving style, transmission and city vs highway but id imagine at low rpms itd be the same as the b7...

Im thinking about ordering this from hmo and should i just buy the long block with the p08 ecu? And will my tranny work with it? Or should i get the 5 speed hydro tranny? And what site is best for just eg hatchbacks? Thanks.

Your stock transmission will work with it. If you want a little more acceleration, the D15B transmission would be the better choice (or one from a D16Z6 or D16Y8). But if you care more about mpg, the stock one will be better.

You should get the P08, unless you have to do emissions testing (then get a USDM P28). One thing with the P08 is that it looks for a 1-wire O2 sensor, rather than the standard 4-wire one.

It should just drop right into the car. You will need to wire VTEC though, unless it comes with a harness.

How do you wire for vtec? Or where can i buy a harness?

search the forum for a writeup. Its pretty simple. I know how to do it but I dont feel like explaining it here since its already been posted before. Its really just about 3 wires.

You'll want the D15b, D16z6 or Y8 transmission. Fuel economy will still be good. And honestly, gearing isn't everything. How you drive affects it a LOT.
