Here is my recommendation:
1. Nippo Supra TT pump (a straight drop in)
2. SX or aeroquip Fuel pressure regulator
3. Bosch 160lb top feed fuel injectors
4. KgParts secondary fuel rail
5. 4-6ohm injector resistors

This setup worked very well for me and will give you enough capacity for at least 400rwhp.

With those mods,if you plan on running 360-380 hp you definitely want to upgrade your ecu.

Which ones are the 160lb ones? The 1000cc or the 1600cc?

CMonakar

160lb/hr =1680cc/min which are often referred to as 1600cc injectors, because some people believe they only flow 1600cc and other people don't realize the conversion factor is 10.5 not 10 . . .

You would definitely need a programmable ecu to use them. I assume you already have one with the mods you listed.

Right Chris, but there are also 150lb injectors out there that are passed off as "1600cc" even though they flow 1575cc.... if you ever doubt an injector you can send them to us to flowtest. For a set of 2 injectors, the cost (including return shipping for rotary applications) is an entire $12. Fair price for some peace of mind....

He won't be able to pass smog with those injectors. His only option to pass smog is to run bored-out secondaries.

Aside from all this, with those mods, you shouldn't boost more than 10 psi. If you have an aftermarket ecu with those mods, you shouldn't boost more than 12 psi anyway. So no fuel upgrades are required. You need a better intercooler and ecu first!
