So I’ve just about ordered every part for my up and coming build but I have a quick question about the fuel injector sizing…

Here is a basic run down of what my B18C5 build consists of (from my previous post CHANGES):

Head:
- Fully port and polished by Gord Busch Performance (in Mississauga)
- Port matched intake manifold
- Skunk2 Pro1 cams
- Skunk2 Pro cam gears
- Ferrea +1mm intake valves
- Ferrea exhaust valves
- Ferrea valve springs
- Ferrea Ti retainers
- Ferrea Seat locators
- Ferrea Valve locks
- ARP head studs

Bottome end:
- Weseco Pistons (81.5mm 5cc)
- Carrillo Rods

Other:
- RC 440 injectors
- Honda Bearings
- Honda Valve seals
- Honda head gasket

Parts I already have:
- Mugen intake
- Mugen twin loop
- High-flow cat
- Spoon header
- Hondata S300
- PLX R-500


I tried to get RC 370 injectors but my supplier didn’t have them available so I opted to order the RC 440s. The guys at Skunk2 tell me I’ll have no problem tuning the Pro1 cams with these injectors (a la Honda S300) but I want to get some second opinions. My main concern is being able to get the engine to idle smoothly with these large injectors. On the positive side I know I wont max them out

My guess is that running these injectors at 50psi will likely result in a maximum duty cycle of 50-60%.

Any thoughts?

Oh, parts should be arriving over the next month or so…

 

You will be absolutely fine... Yes they are a bit large for your setup however with a decent tuner you will be good. For example I just tuned a b16a on 6psi with 750cc injectors using crome pro and it is flawless

 

I ran 440's on a very similar build with the same cams and it idled fine-after much tuning.

 

Tuning is the key.

yes it is. 440 is fine especially if your going to be tunning it with hondata

 

Thanks alot guys!

This definitly makes me feel alot better about choosing them. My other option was to get 310s but I figured that might be getting a little tight.
