Default Fuel injector and Engine management questions...

Here's my current setup:
1994 Integra LS

B16 Shortblock:
Resurfaced Deck
Benson Sleeves
Micropolished/Chanfered crank
Balanced/Blue Printed
Crower Rods
Arias Pistons
New clearanced bearings with thrust washers


VTEC Head from a 95 Delsol:
Resurfaced
Deburred combustion chambers
New valve stem seals
3 angle valve job
Custom grind Web cams (setup for forced induction)
Completely ported/polished Del Sol head
Stainless Steel undercut and swirl polished (intake & exhaust) valves
Titanium retainers / highrev springs

Turbo setup is still undecided...

Basically, I'm shooting for 450hp-ish, and 11second time slips...

2 Things I'm sort of wondering about...

First, what am I going to need for injectors? I plan (hopefully) will be using the Hondata stage 4 for engine management, but I have no clue how well it will handle large injectors... I want to run big enough injectors to keep things safe (20-24psi at the track), but, I don't want to go soo big that the car won't start/idle. (Its an everyday driver, so I'll most likely be running 10-15 psi on the street, and around 23psi at the track (couple of times per year)) ... Driveability must stay decent, but I don't want to risk melting a piston just to keep it driveable..

Second concern... What TYPE of injector can I run? (peak and hold, or saturated) - and will I need to do any sort of weird wiring to make them work?)


Thanks!

I think that you would be good with some 550's saturated....

For 23psi/450+hp, I think you'll want a set of 720cc injectors as a minimum. The Hondata will be able to handle it just fine at idle and such, and I belive you're looking for Saturated injectors.

Will I be able to run saturated injectors without doing any special wiring? <I've heard some people mention something about a resistor box? Not sure if they were talking about needing it for peak and hold injectors, or saturated...> ...

Thanks!

The biggest saturated injectors that rc sells are 440cc anything bigger will be peak and hold. You will probably want to get 720 with your set up. If you have 95 or older you can use your factory injector clips. If you have 96 and newer you have to buy clips and a resistor box. You can get the clips from rc for $40 or so and you can the resistor box from a place called flyin miata in colorado, it cost $50 and it is very easy to hook up.

are you sure about that? http://www.rceng.com has 550's and 600-800 listed on the site, unless you meant 440's are the biggest that will fit on his car.

when I called rc about getting some saturated 720's they said they don't offer anything bigger than 440 saturated anymore. I talked to Wayne, he did'nt say why.
