maximum hp you can get from stock gsr cams
Like the title says. I have a all motor build and I was wandering who has experience with stock gsr cams and the max HP u can get out of them. I'm getting a tune soon for this build need an estimate of power. Can I break 200 HP with out new cams and injectors?
My motor :
GSR Cams
11:1 comp 81.5mm CP pistons forged
Eagle Rods
Supertech Head Guard
3 angle valve job
Crower springs and retainers
R.e.v. valves
Skunk2 pro intake mani
N.O.S. Direct-port fogger Sport System
Wrapped greddy header 4-2-1 2.5" collector
I actually have plans to bump my direct port nitrous from 80 to 120 shot. and heard that gsr cams are great for NO2. I want my final output at roughly 300 HP

I can't speak for the NO2, but all motor, no you aren't likely to break 200 with stock cams and injectors.
I've seen higher compression B series, with cams, peak at like 190 cause of stock injectors.

I really didn't think it was possible but I thought it would be best to ask

200 is just hard in general for stock 240cc injectors, even prelude 310s peaked on me at around the 205 range on my JDM H22(stock internals, every bolt on imaginable)
I'd say keep your cams, get some DSM 450s and call it day(got my H22 to 220's after a quick retune, with room to go)

No, stock injectors out of a DSM(4G63 Eclipse/Talon)
You can find them in the classifieds here all day for like $40-75, I personally paid $40 for my last 2 sets that worked perfect.
You may/may not need a resistor box, the older sets were full impedance, newer are half impedance, or vice versa. Can't recall right now.
They use Bosch style plugs already so they plug right into a Honda harness.

You can push stock injectors plenty past 190whp.
And you can push 310s alot further than 205whp..
I've had SEVERAL all motor b-series ranging from stock ITR swaps to 12.5:1 LS motors to my current setup (I'm a turbo guy really).
Stock injectors held it down at 210 several times. My built LS motor had 310s and this B20vtec setup does too.
PRESSURE affects where the injector peaks at. Turn it up a little.
And OP. Put some cams in that fucking motor.
