Re: 99 Accord v6 Engine swap compatibility
J series engines have very similar blocks, its the change in the cylinder heads/intake/exhaust that increased the power.
98-02 J30 200HP
03-05 J30 240HP
06-07 J30 244HP
The other difference is the 98-02 had a 4spd AT while the later cars have a 5spd AT or 6spd manual.
Swap in a later J30(if you want to stay 3.0) with the appropriate transmission and wiring harness, but that would require modifications to make work with your older Accord.
Comptech did offer a supercharger for the 98-02 along with their headers net ~225HP to the wheels, so if Comptech still has this kit that may be the easier route rather than trying to swap in a later model engine/trans.

Re: 99 Accord v6 Engine swap compatibility
I have a 2005 Honda accord hybrid with 3.0l i-vtec, I swapped the engine for a 2007 Acura RL SHawd 3.5l vtec. I bolted all the hybrid components on to the 3.5l with no problems. And, it runs great for the first ten miles. Then I get a check engine light and it shuts down at 3500 rpms. I gives the PO 2648 which has something to do i-vtec solenoid wiring. The 3.5l is vtec, no i-vtec solenoid. Does anyone know what l have to do to the engine bay wiring harness to fool the computer, or in other words which wires do I change or cross to make it work?
