Please DO NOT Post In The General Section

From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.


The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.


For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.


Everyone will get a couple of warnings from here on out, after that I just start deleting threads.

Again if you have any questions, PM me or one of the other mods.

    Fuel injector suggestion for small turbo

    I've seen a couple of fuel injector-related threads on here in the past few weeks so I thought I'd share something I've found while researching. The RDX injectors are commonly suggested as a decent injector for Honda applications because of their slightly increased fuel flow capabilities, as well as their relatively inexpensive price. What's also touted fairly often is their vastly improved spray pattern. I've even claimed as much myself. All of this is true. It does do all of these things well.

    However, I believe there is a better injector available now that edges out the RDX injectors in terms of its benefits. The '13-'14 Ford GT500 injectors are even higher capacity AND are Bosch EV14-based. EV14 is the platform that all of the Injector Dynamics, FIC, Deatschwerks, etc. injectors are based on which is a proven design for high HP applications. They are also very capable when operating in the lower range of their duty cycle, allowing them to idle better than many older injectors. Especially the Keihin injectors these cars came with.

    Here they are

    RockAuto seems to be the best place to find them as they have them for $31.79/each.


    They will still require hats to fit them into the OEM rail, as well as adapter harnesses or for you to modify your factory wiring harness to change to an USCAR-style clip. They are 57 LB/HR injectors which translates to 600cc/min.

    My Members' Ride Thread - It's a marathon build, not a sprint. But keep me honest on the update frequency!

    you can also get the light blue older wrx injectors and decap them. this will yield a 815cc injector that works great with our stock rail and intake ports
