Injector size??

Hi all, just installed a s1 erl system in to my skyline and I'm trying to work out how many/ what size injectors to use and where to mount them?

Car has a 2.5 straight 6 and will be running upto 20psi.

I was thinking of one jet about 8" from the t/b and one in front of the turbo or after the turbo but before the intercooler.

Any advice would be grate!

The 1S system will only support up to a single 1.0 jet and 330cc of injection.

You would be best to on-sell your current system and use an HSF-3 system which will allow for a greater delivery of injectant.
The older ERL systems are limited to 330cc per minute and would not be enough for your engine.
Have a look around the Howerton Engineering or Aquamist sites there are flow calculation charts there to help you figure out how many cc per minute you would need.
My 2c worth.
