Hi all. I’m in the process of converting my stock 1.7 to a big bore 1.9 and was looking to keep the stock fuel injection system if I can. I would just like to know if this is possible and how the original FI is tweaked, do I need to fit bigger injectors and mess with the throttle position etc etc. I’ve been told it’s possible but would like more detail so that I can continue. There must be quite a few out there that have done the big bore so hopefully someone will jump in. Thanks.

QUOTE(914_teener @ Jan 30 2020, 10:10 AM)  Time it.s all said and done for a 1911...might as well go to 2056. Just saying. I disagree, unless you have to spit your case for some other reason. If you suspect your bottom end to need work, then yes go get the 2L crank. If your bottom end is suspected to be good, don't split the case... don't touch it! That will open a larger can of worms that will add a few grand to the overall build price when you consider the new bearings, new cam, 2L crank, machine work, etc. Zach |
