I am in the process of installing a cc306, afr 190cc street port heads, 1.6 rockers, and I may run a 100 or 150 shot of N2o down the road. My question is, do I need to upgrade the fuel pump, and injectors? If so, what size and brands do you reccomend? Thanks in advance, Tom.

 

I would uprgrade your fuel injectors to SV0 30 lber and go with an intank Walbro 255lph.

 

where can I find the Walbro 255 at a good price. Thanks again, Tom.

 

And would it hurt or help any to upgrade to like a 26 lb or 30 lb fuel injector withour any major engine mods??

 

The only reason I recommended going with 30 lbers is because he is getting his heads ported and running an aftermarket cam. He will benefit from this. If you are running a relatively stock car and want to upgrade to 30 lbers you will be wasting your money.
