I searched, but there is about 16 pages of hondata, injector and fuel pressure stuff...
so my question is, at 7-10p psi, with hondata and 440s, would I want an intank and a FPR, or will the stock pieces be adaquate..

Not entirely sure. But you can get a walbro intank fuel pump for no more then $120.

I had a walbro intank, and 450's...ran great at 10psi on they dyno....

Have piece of mind....get the walbro.

for 7-10 psi you can be just fine with stock. i have tuned a few hondata units with that kind of setup and it was perfectly ok.

I think you would want to get atleast an intank pump, like the Walbro as suggested. I run a Walbro GSS342 and 1:1 FPR at 6.5psi on my setup, works great. Personally I wouldn't settle for stock stuff when doing these kind of mods to the motor, but that's just me

I would say the engine is worth a $120 fuel pump.

brandon, going boost. you can always trade me for my 99 boosted gsr for your itr so you wouldn't have to worry about fuel problems. currently running some 850's and an aeromotive.

but yes, even with hondata, upgrade the pump.

If I boost the ITR it will be because I'm bored and I need a project. I like working on my car as much as I like driving it. so with the walbro, stock fuel pressure will be adaquate?

for some reason i havent been able to back the fuel pressure down with the walbro pump, I have tried a 255 and two high pressure 255's and the lowest i could back any of them down was to 50 psi with the vac. hose on. I am using a stock pump with some rc 500 and a hondata and it is working fine so far.
