150HP with Blitz?

Through a lot of collaborative efforts with Scott and my tuner we have actually been able to determine a LOT about what you can expect from the stock fuel system and 1zz injectors. Just installing the injectors alone will give you a little more fuel, but also bumping up the FP will make a big difference too. I would not go any larger than 1zz injectors for a reliable build as you will just be wasting a lot of fuel and money. You have to decide which mentality you are going to take:

1) all I care about is numbers
2) all I care about is getting to whatever speeds I want in the shortest time
3) I really want to have the most fun that I can for the least amount of cash for the longest time

One thing to remember is that the 1zz injectors aren't really that much larger than stock. There are tons of folks out there that think throwing bigger injectors are the cure for adding more power. No matter how you slice it for every pound of boost you should be going up 1psi of fuel pressure. With a stock regulator at a static 43/44 you leave power on the table as well as lose longevity of the motor. Sure, some may argue that 6psi of SC boost isn't enough to really matter, but it does. It is kind of like having a turbo with no additional fuel management and running 3-5psi. Sure, you can do it, but if you are going to make the investment why leave so much on the table and yet deal with the possible risks.


P.S. > I get asked all of the time what numbers I am putting down. Honestly I could care less as long as I get the results I want to the pavement, have fun, and at least have some semblance of not sitting in a gas station every other day. Numbers are numbers...just that. Have you been in a 150hp Yaris yet? if you haven't really how do you know what you truly want. You could very well be happy with a 130hp build or 150 may not give you the effect you are looking for. Lastly, different dyno chassis provide different numbers as well as different results depending on environmental variables. Just food for thought.
