They have 91 hp(hehe) and you can make a bit more power by intake, headers, ect. If you want you can put the si motor (d16) in and it would be really easy to do. Brad and I did it in about 3-4 hours. Then you could do I/H/E.

The D16 is very similar to the D15- different head and crankshaft and multi port fuel injection (MPFI) if I have my stuff right. NON Vtec. You need a PM6(?) ecu (not sure if there are any others that will work) and either a complete MPFI harness to swap or you need to do the MPFI wiring conversion. DX,STD (DPFI) -> Si,HX (MPFI) wiring
If you have a brand new D15B2 I would recommend getting a header and exhaust system, and upgrading to MPFI. This way you can swap in an engine much easier when the time comes because your wiring will be "up to date" in a way. But I beat the living hell out of my D15 for 3 years and loved every minute of it.

I only had my mpfi swapped d15 running for about 3 days, but it definitely seemed to have more go. And as far as I know it helps to have the swap done if you want to do a full engine swap later on.

the mpfi is better because of the injectors you can always upgrade them and its just less hassle than having a carb. and go with the si swap its worth it and i mite have the pm6 ecu layin around ill look and those motors are easy to come by.
