Is this a Swap or a direct Bolt In?
 

Forgive me if this is a stupid question but I need to know.
I have a Civic DX '94 edition with a D15B7 @ 102 hp with stock parts.
Now my engine is not stock but I have only modded the throttle body, intake, exhaust, and spark wires and plugs. Sure it is pretty peppy on the road but I was interested in the D15B w/ VTEC and 130hp.
First question is, and yes it may be stupid, but will the D15B replace the current engine I have just by direct bolt-in or will I need to put in extras in order for this engine to work in my current car? I know this might be a dumb question because they are both D15 size engines BUT they are from two different markets in the world and I don't know if I need a new ECU, wiring harness, mounts, or anything else I am not thinking of. Its a good increase in horsepower and I saw an engine for sale with low mileage locally and my engine is blown, repairable but blown, and now I am considering a new/used engine instead of rebuilding the block. The block is getting incredibly high in mileage and I think its best to get a not so worn engine. ANY help is very much appreciated!

It is a direct swap, will bolt right in. Youll need a P08 ECU to run it to its potential, but you can run it off a P28, thats what i did, and was not dissapointed. Whichever ECU you go with, you will have to wire up the VTEC pressure switch and manifold, but this is easier then it sounds and you can find wiring diagrams to do this all over the place.
