| Can I build a bigger engine like a 1776cc or 1904cc and still use the the stock fuel injection system? |

Consensus:
1776: yes, though you will run out of air above about 4500rpm due to the intake runner size. You will have to at least bump your pressure a couple of psi, and may consider using larger capacity injectors. In either case I recommend you get a wideband O2 kit and install the bung in the resonator right at the exit from the muffler, then adjust all three MPS settings. I did this and it works well.
1904: not feasible from a breathing standpoint; you won't see the better power. since it can't breath.
Stick with a stock or very near-stock cam profile, or the MPS will not be able to figure out what's happening, even with adjustments. |
