Whats a good size injector to run on a streetported 13bt on the stock ecu? Can i run like a 750 or 880 with any problems?

 

plenty of info just search..... if you haven't upgraded your fuel pump yet, don't even bother upgrading the injectors, the walbro fuel pump seems to be very popular. ( that's what I've got ) I don't think you'd have any problem running 720cc or 800cc secondaries, but if you don't have an AFC, you may run pretty rich.

 

i agree you should search injector sizes have been discussed millions of time. Although i would try some kind of upgrade in management if i were to change the fuel system. you could probably pick up a rtek ecu for cheap. search...
