they work ok...i heard anything over 310 and the engine gets flooded, but sgt told me to get 440's...i have 81.5mm high compression...will the 440's work ok with this setup...doing hondata real soon as well...

 

i have 440's in my R

 

i am going all motor though...you are turbo right...what is your fuel psi at

 

I have a set of 440's in my car...stock compression, without a FPR, although I do have a programable computer(A'PEXi PowerFC)

I'm running Toyota 440's with Toda 81.5mm pistons, Spec B's, lots of other goodies, and a Hondata ECU. With the Hondata you can go much bigger than 440's on a n/a set-up and you won't be using too much fuel. That's the whole point of a programmable ECU, you tell the software how big your injectors are and it's very easy to get the fuel maps sorted out from there. Duty cycle with the 440's is fine, no worries there either. If you went too big (say 720cc +), the software might not be able to compensate fully but anything smaller is easily dealt with by the Hondata unit.

 

great thats what i wanted to here

 

So I guess the most important thing with bigger injector like 440cc on a N/A car is that you will need a programmable ECU to make it work well?

 

yup. stock ecu can't compensate for anything bigger than 310's.... you could chip it though...

and for those thinking of running toyota 440 injectors, do a search; many have had problems with them. Better to get something off a turbo dsm or from rc engineering...
