2JZGE TIG Billet Intake manifold W/ fuel rail & Throttle Body Supra SC300 IS300 | eBayThe 2JZ-GTE and 2JZ-GE fuel rails and mounts/spacing/etc are very different so they don't interchange.
You'll need a rail to match the GE that comes with the intake manifold you use, or you can just use the stock GE rail.
On a 2JZ-GE (VVTi or non VVTi) fuel rail, you'll need 60mm long, 11mm inlet 'import' pattern top feed injectors. Preferably high impedance, but you can add a resistor pack if you really want to for some reason.
The stock rail is ugly but works just fine - You can use metric to AN adapters to replace the stock banjos and hard lines. Depending on your intake manifold setup there's lots of ways to mount an AFPR to the rail itself (not my favorite method) or run a small section of hose from the return side of the rail to mount the AFPR somewhere else. You can always run a 6-AN 90* off of the stock return line port, run that line back to the firewall, and have the AFPR mounted there with the return line going down from that. Nice and tidy if done with some due diligence.
If you're running an Ebay FFIM like the Deepmotor or similar, it should come with its own fuel rail and you can just use that. Most of them are set up for the 60mm long/14mm inlet 'domestic' pattern injectors, so you'll want ID injectors sized accordingly. Radium does not offer a GE rail AFAIK, and the mounting patterns/injector spacing is very different between the GE and GTE heads on the JZ's.
You can often re-use the stock injector -> manifold runner seals on your aftermarket injectors, just use lithium grease or similar to make them slide in nicely. Some fuel rail kits will come with weld-in injector bungs to perfectly suit a given injector, and that's an ideal solution if possible and tends to prevent boost leaks and other issues.
That's more common with the GTE's because of the factory side feed GTE injectors having some goofy injector seals as well.
Planning on the one you suggested to me a while back. Yes it comes with a fuel rail, but I dont know how it mounts to the manifold. Or if it has a fuel pulse dampener port (Doesn't look like it)
And isn't the IS300 Fuel rail the returnless one? And are you suggesting doing the AFPR on the return side of the fuel rail, as opposed to controlling the pressure of the feed side?
I'm going to assume 60mm injector is considered "full length"?
