Hondata tested the DC5R intake manifold and only got a few horses out of it in the 7500rpm range. It has 3mm larger diameter in the runners over our A3 and A2 IM's. The A2 head is worth at least 20whp over a stock EP. *(untunned)

Things that would also need to be done with the A2 head include relocating the vtec engagement (~4500rpm) and revamping the timing/cam angles to get full effect with the lower compression. I plan to use the A2 hondata map provided with the programmable ECU and tune from there.
