Default How much HP are stock LS injectors good for?

Building the LS motor(sorry, new to Hondas..) I was wondering when do I look at upping the size of the injectors and/or fuel pump?

I'm hoping for 150-160 WHP with my setup:

B18A1
PnP Head
Crane #12 cams
P30 pistions(around 11:1)
maybe PnP intake manifold
I/H/E

Sounds like Erik's Racing chip in the PR4 ECU... Hondata can't do it because its OBD0 :-(

Will the stock injectors be able to handle this with just maybe a FPR upgrade?

Thanks!

Yes your injectors will be fine for now...new injectors are need when you're getting ready to start adding boost. (200+hp) when you start adding fuel you need to make sure you have the oxygen to combust that fuel.

Thnx!

I'm going to have them cleaned and flow tested before reassembling the motor, to make sure they are in good shape.

Technically, the stock LS injectors will max out around 146-150hp, according to the industry stantard of 80% duty cycle and 50% BSFC. Stock LS has 240cc/min injectors. And, boosted engines may see 60%+ BSFC. So, all motor 150hp using stock injectors should be OK.
