Fuel Supply for 5.3 Liter with 11:1 Compression

[Lextreme II]

Hey Guys,

I am just thinking these in my head. Want to do a high cubic, high compression motor. Stroking the 4.7 to 5.3 with 11:1 compression ratio along with mild cams and high flow hearders. These combo should bring the 250 bhp around mid 400 bhp. I wonder what size of injectors would be ok to use with 1uzfe heads. I know the Tundra (4.7) uses 275 cc. Perhaps I should consider the Supra MKIII yellow top (295 cc). What about computer. Stock computer?

330cc. Without some extra pressure, Don't go below that. (Those are actually a great match for what I think you're wanting to do. They're definately more than you need, but not huge - so the tuning is easy.)

as long as the resistor pack is included it shouldnt be more than 8 wires to splice to add i t or if you want to run high impedence or low impedence injectors... stock computer should be fine, just get a piggy back SAFC-II

Actually I was thinking of without piggyback. Just plane stock ecu with either 295 or 315 lime green top with walbro fuel pump.

I'd still be on the 330's. Between some minor fuel trim corrections & some things you can do to keep the fiel trim corrections small, I think that would still be better!

These walbro fuel pump ,what HP are they good for?

With the larger 255,it can feed a turbocharged 2.0 liter engine that makes over 500hp at the drive wheels. I built the engine and watched it dyno.

Thanks,so should be good enough for same in a V8 application then..
