I am about to buy some new injectors soon and wondering what you guys run and which are the best. Thanks

 

Depends what you're trying to accomplish. There is no "best injector". You need to figure out what your needs are, then match the injector to meet those needs. If the car is stock, you don't need 800 cc primaries and 1300 cc secondaries, now do you? Running "Blowzilla"? You can't go with the stockers. Figure out what your needs are, how you plan to control them, and go from there.

 

rx7.com has a calculator for how much hp certain injector combos are good for.. that may help with what $100T2 was saying.. theyll also tell you side effects of running too large and how to correct it..gonna need something to tune the fuel too

 

550 and 720 just trying to find what brand is the best

 

ohh i understand.. venom and rc engineering seem to be very reputable brands.. and rtek1.7 will handle your ecu situation for very reasonable price

 

Yea i was planning on the rtek 1.7 550 and 720 injectors for my s5 hybrid turbo. Plan on like 10psi may need a better fuel pump not sure yet though.

 

sorry

 

you may also need something to tune the secondaries still if youre going to boost more than stock.. and yea a better fuel pump couldnt hurt and with your plans of just upgrading secondaries and not boosting tooooo much.. you can really pick from a few different pumps FD, cosmo, walbro etc but i still say youll need something to tune those secondaries to keep your afr's where you want them under the above-stock load

ps whats hybrid about your turbo?

 

Its a bored out stock s5 housing with a 60-1 turbine. Was done at some turbo shop kinda like a bnr stage 1 or something picked it up for $300.00 was going to use it for my 10th anni build up but i will find another one.

 

what do you mean you will find another one.. that sounds like its gonna be a really good turbo setup you got going on.. youre gonna get nice power outta that but with a 60-1 compressor youre gonna need to tune the fuel up beyond rteks set up.. aaaactually id prolly be better to get rtek2.0 as it has standalone ish capabilities to tune fuel and spark and will give you a nice stock map for 550/720 injectors at the check of a box
