I plan on doing some power upgrades in the near future and upgrading the fuel system is something I'll e starting with.
I'll do a top feed conversion for my 2005 STi, then install 1200cc injectors. I already have a Walbro fuel pump which should help. Also, I've heard mixed comments on whether stock fuel rails can handle anything over 400+ hp. Comments on that?
Here's the question. In Minnesota, it gets down to below zero in the winter. Has anybody had any cold starting issues with the larger injectors in really cold weather?
Thanks
