DESCRIPTION

Direct Injection fuel system upgrades for the B58 Gen 1 is here! Precision Raceworks Stage 1 and Stage 2 injectors are for those looking to push their B58 Gen 1 to the next level without the need for port injection!

Inside the box, you will find everything you need to get your new injectors installed quickly, including detailed installation instructions. When you are ready to tune, we have injector tuning data available for your tuner. Being that everything is installed like a factory part, there’s no need to worry about secondary injection controllers, filling meth tanks, clogged meth injectors, or any of the other complex solutions people use to squeeze more power out of these vehicles. Additionally, these injectors are operating with all the OEM ECU’s engine management system diagnostics and safety functions – resulting in a much happier and responsive system!

This product is backed by a limited lifetime warranty. Our products are comprehensive solutions that come complete with everything you need inside the box, including detailed installation instructions. Tuning guides are also available for your tuner. We have customer service on staff to provide you with any support that you may need, from installation to tuning.

FAQ's

Will these work in a Gen 2 B58?

The Gen 1 injectors are intended for use only with the Gen 1 B58.  The Gen 2 B58 (like found in the SUPRA), uses a 450 bar high pressure fuel system from the factory, where as the Gen 1 engine uses a 250 bar system.

I see a lot of mentions about OEM equivalent spray patterns. What does that mean and why is it important?

While increasing flow rate is critical to making more horsepower, there are other factors to consider when choosing fuel system upgrades. A bigger injector isn’t always a better injector! It can flow a large volume of fuel at WOT, but if the spray pattern is poor, you can expect poor idle quality, poor drivability, increased knock propensity, soot, NVH (noise vibration harshness,) and tuning difficulty. Additionally, the wrong spray pattern can result in liquid fuel impinging in the cylinder walls, causing oil dilution, which increases mechanical wear to internal engine components.

Precision Raceworks is committed to providing only quality products, and has developed partnerships to deliver an OEM level of quality on our injectors.
