Direct port nozzle sizing?

forcefed86 · 04-24-2008

Shooting for 30lbs on 91 octane with a 62mm turbo. (850cfm) On my 3.0 NA-T sc300 lexus. What size nozzles would I need to run?

Also with the additional strain of 5 extra nozzles is a pump upgrade necessary?

Thanks!

Great kit BTW...

The intakes are actually pretty good for air flow for those engines, Have you ever though about just doing dual nozzles like the red circles below.

I've heard they atomise well. What size nozzles would U suggest for my goals usinf a dual setup.

I was trying to use the methanol inj. not only for antidetonation but also for the required fuel to get me to my goals. I'm maxed out on my 525 injectors at around 450hp. So I was thinking of upgrading to a 67mm turbo and using the direct port setup instead of upgrading my petrol system....

I"m at 422 rwhp right now and I'm shooting for 550+

Thanks...

Dual M5 nozzles would be what you want to use for that set up, And a Stage 2 kit with 3bar controller.
