Don't skimp on injectors. Get the biggest you can find. There is NO problem tuning any size injector down to 1.3ms if the tuner is worth his salt

I recomend the Lucas/Delphi 42lb. injectors. I have them in my car and they work great. They are very easy to tune. I got them from Harris speed for $289 which was the best price I could find at the time.

55lbs Siemens I like. If you want bigger than 60 then you will need to run a driver box, then I would run the 83lbs Siemens.

Siemens 60's get the job done at a reasonable price. Plus if you decide you want more power in the future then you are covered.

RC Eng do 73lb highZ injectors.

And there are other brands now, up to 96lb in highZ if you are that keen...

But 60lb Siemens/Mototrons will handle lot of power, and work superbly.
