Injector Option(Hey they're Free)
 
Ford 35# 350cc Brown Top Fuel Injectors from a 1988 Thunderbird TurboCoupe
Friend has these and will give them to me, his dad just wrecked his car and the still work great and they very clean!!! Read somewhere theat they might work.
I know they are only 350cc but eventully will go to 450cc, but for know has anybody heard of using them?

Hahaha I just put that same set into my car this past friday. They were also free because I had them laying around from my parts car 86 Thunderbird turbo coupe (I also owned an 88)

Anyways I'm not a honda but they work well for me...its as large as I can go with my stock pcm well actually they are a lil too large but thats ok by me I just run rich until WOT.

Mine are brown tops as well, excetp one is a gray I'm guessing it was a replacement injector....

62 psi fuel pressure at the nozzle will give you 420cc/min of fuel delivery, if you need it.. 71psi will give you 450, but 70psi is pushing it (remember, rail pressure goes up 1:1 with boost. if your base pressure is 70 psi, and your'e running 10psi of boost, even though the pressure at the nozzle is still 70, the pressure in the rail is 80psi. most injectors are rated to about 70psi, and stomization is actually better at higher pressures (my old FSAE team has dyno charts to prove this). if you hardwire the fuel pump, it should help out the flow at the higher pressure..

Thanks guys. I'll give them a try, I will have to rewrite a program for the ECU but I sould be able to get them right!

i've never heard of boost raising fuel pressure unless u use a boost dependant regulator.. what car are u referring to?

I have to agree with crx88si I haven';t heard of it before either

Much like engine vacuum lowers fuel pressure from the base 41 psig, throwing boost at the regulator raises fuel pressure.
