It is easily the most common pump upgrade for TII owners. I have one and know many others on here with it.

No, they will work in NAs. But there is no need for one in an NA. If an NA needed a bigger pump, a TII one is plenty big enough.

Its good..

the 255lph one is pretty much the 'standard' upgrade once you get more than a few mods (ie. full exhaust)

Not only not worth it.........it will cause you PROBLEMS. We don't need anymore problems. Don't do it. Nothing to be gained, everything to be lost. Just my opinion.

The stock injectors hit about 100%DC at 290rwhp? Ive heard it can cause injectors to crap out running them that high. Never experienced myself though

Remember you don't have a stock turbo or injectors so no one will really know(that is if you asked this question for your own setup purposes).

Yea I believe its about 330hp at 100% DC. Even with the injectors at 80% duty cycle it would be 260hp just that the ECU limits duty cycle.

Does the walbro plug right in or is there additional wiring that needs to be done?

Will it affect emmisions?
