But that doesn’t mean everyone wants to run the exact same engine.
FiTech Fuel Injection is probably most commonly known for their fuel-injected throttle bodies that allow car guys (and girls) to easily replace their carbureted setup with fuel injection. But the company has also developed a wide range of port fuel-injected intake setups for LS engines that never came with carbs. And it’s turned out to be a pretty comprehensive kit as well as a great way to improve performance.
In addition to the ECU and wiring harness, there are a number of options to choose from depending on what you need. For a stroker LS1 build we have going together, we went with a nearly complete kit that also includes a long-runner fabricated intake, big 102mm throttle body, fuel injectors, fuel rails, fuel pressure regulator, handheld controller, fuel pump, coils, and a ton of sensors, connectors, fittings, and everything else needed to get it all working. As a system, our kit is designed to be able to handle up to 750 hp.
What we really liked is all the components have already been scienced out as a package so you can be confident everything fits and works well together. That eliminates all the head-scratching that often comes from mixing and matching components from different manufacturers. Plus, that fabricated aluminum intake manifold just looks sweet. Obviously, looks are not a primary consideration when it comes to an engine build, but let’s not pretend that looks don’t matter at least a little bit. After all, everybody wants a little eye candy when they pop the hood with your friends standing around.
We’re sure you are ready to get to it, so we won’t waste more time yapping. Follow along as we assemble one of FiTech’s Ultimate LS kits on a big-inch stroker build and then put it to the test on an engine dyno.
