Just trying to get some info before i install this kit. I would like to upgrade the injectors but i plan on getting a nice MSD ignition box or one of there other boxes to pull timing. Should my stock injectors be ok with 125 dry shot? What is a safe Fuel pressure w/125 dry shot?

Yes!!!!
Do you REALLY want to take a chance on building a motor compared to a $219.00 purchase?

Stock injectors lock CLOSED, SVO's lock OPEN.
BOOM or live, it's your $220 choice.

In that case I will run the 100 shot instead of the 125 until i get injectors. I dont think im runnning enough nitrous for my fuel pressure to peak enough to lock up my injectors. I mean what do they lock up at? I've always heard never go past 125 shot on stock injectors or you will chance FI lockup. Oh yea, where can I get those injectors for $220? Are they stock lbs/hr?

Summitracing.com for SVO 30lb injectors.
I really wouldn't risk blowing your motor over even a 75 shot...
I'm just careful though after spending $7K on a "cheap" stroker buildup.

Hmm. Im definetly gonna get some injectors. Especially since Im gonna do head/cam and will surely need new injectors then. And for $220 a cheap insurance that your engine is much safer is alot more easy on my head. I guess my next few mods will be, fuel injectors, ignition box, new intank FP to replace the stock pump. I may still keep the inline booster pump that came with my kit. It seems like a nice pump. Its made by Walbro also. Anyone else wanna chime in? I'd like to get more opinions. Thanks for the reply btw MTXpert. Seems like you know some about nitrous since you about to have a stroked 250shot engine.

Edit: Damn nice lookin Impala btw.

Thanks for the compliments.
I ran a dry 175 shot in my bolt on motor for 18 months before going to a stroker.

Here's my list of mods for the nitrous:

The only thing that's not listed is the injectors as they were done previously.
