Is it a shell or have engine problems? The b18c1 is a great engine, personally I wouldn't swap unless the b18 had to come out anyway...but that's just me...
If it's a real DC2 then why swap to a engine with 30-45 less hp? The DC2 are a GSR or Type R. If you don't have them, then you have a DC4, which has the normal B18B in it non vtec, not the B18C1 or B18C5 which has vtec. Post a picture of the engine.
^ good point... When i read it, I kinda just assumed he meant swap blocks and stick with his current head, but that's a probly a bad assumption. Not to mention a fair amount of work for not all that much gain...
