turbo fueling!

hi there!
when using the 450 or 550 cc injectors, do they fit in the original fuel rail, or do you have to build a custom rail?
also, what boost can a standard fuel pump handle?
is it better to by one large fuel pump or is it safe to run two standard fuel pumps?
thanx

Re:turbo fueling!

id say 10psi is the max safe daily driving limit of a stock pump in GOOD shape. Also depends on how your are controlling fuel. If you plan on a FMU GET A PUMP. but if u do the afc hack you should be ok.. but for 100 and your time its cheap insurance.

im not sure about 550cc (what car?) but DSM 450cc's just need to have a injector seal enlarged. Check out the tech projects page for a DSM 450 install.

DSM 550's are almost the same as the 450's I helped my buddy do the switch on his eclipse
