1991 injector question

[mgbrv8]

On the secondary injectors is it okay to run 24lb instead of 22lb or will it run too rich and need a tune? Also some one told me that some horse power can be freed up by cam phasing the cams with some offset keys is this true?

special degreeing the cams can yeild about 10 maybe on the outside 15 hp . on the injectors y you will run way aft unless you get a special tune the 22lb injectors can support alot more power

I was given a set of 24lb injectors and the ones on my car seem too have a little ethanol damage so I was wondering if it would be okay to use the 24lbs. Were do I find more information on cam phasing?

I'm only speculating, but I would guess that putting in larger injectors in stock engine might cause emissions issues, especially if your part of Texas is run by the same SMOG nazis as we have here in NorCal.
I'm sure they'd probably work in your car, but might cause it to run richer. You might be able to compensate for some of it by having a custom tune done on the engine PROM, but that would add yet another layer of complexity in an already complex motor.

Everything you need to know about cam timing.
