Me and my bro's have been working on an is300 turbo build the last three week. Items installed are : CX Racing gt-35 turbo and intercooler kit
Brian Crowler 264 cams
New water pump and timing belt
new seals
And a AMS EMS Standalone piggy

550 Injectors and a walbro 225

My Question is do i need a return fuel system as i will only be running 8-10 boost initially?

 

You can probably get away without a fuel return for low boost (8psi and less).

Also, whats "AMS EMS Standalone piggy" ? lol

 

agreed.

in the long run though, you will want a return style system. There is just no way to cope with a relatively low base fuel pressure when trying to run 30 psi

 

Which ams system are you running?

 

I have been running AEM V2, has been amazing thus far. It is for sale now though, I am moving to AEM Infinity, which is more advanced.

 

Have you already installed the infinity I was thinking about it too but I am not good with the whole wiring

 

Installed and running. It is pretty wiring intensive.
