Without a doubt, no. Time to pick up a fuel pump and hotwire kit. If you have any questions please just ask. Thanks.

As stated above the Stock pump will not hold a 125 shot with the mods that you have. The stock pump is only good to about 450rwhp.

We offer the Racetronix kit's which will net you fueling capable of supporting around 650rwhp.

The stock fuel pump would have worked if you had a stock car on a 125 shot.

With your mods, you will need to upgrade it.

Check out the Racetronix kit!

lol, I think you're going to hate me...seems like I'm saying no an awful lot in your thread.

You're going to be close on the injectors. We usually jump up to the 42's. If you haven't purchased them, I would just go straight to the 42's.

I have mostly the same mods, i also need a new pump. Whats up with the fuel pump wiring harness i always hear about on these ls-1's? Can't you JUST buy the 255lph pump and swap it right in? That what we always did with the old Gen 1's, lol. Whats wrong with the factory pump harness?

The hotwire kit increases the voltage to the pump

The 255 only is only good to about 500 rear wheel. So its not really that much of an increase in performance. The increase comes in with the combination of voltage and a higher flowing pump. There are ways of building your own hotwires to the pump but the racetronix makes for a drop in and plug up type of install. Fpr the cost it is really hard to beat. With the race tronix you are good for about 650 rear wheel hp.

36lb injectors should be fine. You only need enough injector to feed the motor, the nitrous adds fuel by itself.

Assuming, of course, that it is a wet shot.
