Default Fuel pump and injectors question?

So I'm building a LQ4 for a wet plate 250 shot but will probably just run a 150 most of the time.
The question is, will my walbro 255 and fast 36lb injectors will be fine for my set up.
Thanks!

IMO, I would run a standalone for the nitrous. Let the walbro feed the engine.

But my question is that am I not using big enough injectors and fuel pump?
Ill look into the stand alone system. Thanks!

Agreed, I have the same setup but just 200 shot. No problem with getting enough fuel.

All of the lines you have now are fine. There are guys running 600+hp setups using the stock lines, just upgrade the pump and a hotwire kit.

Hmmm 700? on a dynojet? what are you making now on motor?

Agreed on line also, no need unless your trying to go way bigger.

Stand alone is awsome and worth the time if you have the space, my car is a driver and power tour type car so I am not looking for pure race.



That said, i could still put a stand alone in but i dont want to make space for it. i made 486/556 on a 150 shot NX. My haeds are killing my HP but the TQ is awsome!!!!

Don't know what it will put out since its not built yet but I've seen a guy with the same cam and set up but with a 92/92 tsp 5.3 heads and he put down 500 whp also he had a 9" and a steal drive shaft. I'm going to run a 150 shot most of the time but will throw the 250 shot in it once in a while.
