Whats the part number on those evo injectors? And who did you get them from? Someone's bullshitting you man.... Either they are 1000cc, or they arent Precisions... Precision doesn't market 1200cc injectors....

 

^Found a bunch of them with a quick search.
Precision 1200CC Evo Injectors | AMSPerfomance.dk

 

Precision does in fact sell a 1200cc injector. They have for years now. If you all see no differences in RC Engineering injectors and modified Bosch and/or Siemen injectors that just means you have not used enough of them all. I've had multiple sets of RC Engineering and Precision injectors fail or bad straight out of the box. Not one. Not two. But multiple. The last set was on Kirk's MKIV Supra. DSM injectors are like playing Russian Rullet. You don't know the flow variances on each injector, when the filters have been changed, how hard the drivers were driven, etc. I can't remember how many issues I have had with DSM injectors. And unless you've ran 30+ sets you wont. I've had mutliple injectors flow tested only to find variations between sets. I could go on and on. There is a reason I can idle an Injector Dynamic 2200cc injector like an 880cc injector. There is a reason that RC Engineering low impedance injectors like to run at a certain base pressure where a modified Bosch (Injector Dynamics) and/or modified Siemen can run at 100lbs base just as it can at 43.5lbs base. If I can find time I will try todo a back to back comparison between Honda OEM injectors, Injector Dynamics injectors and RC Engineering injectors. Will see

 

Thats weird... Precision doesnt list a 1200cc injector at all on their site.... Learn something new every day....

 

I heard the new Bosch injectors are the shit, but dont have any experience. I have RC 1000's and the only thing I have a problem with is a odd idle, but I knew it was gonna be a problem with big injectors anyway regardless of brand. Other then that DSM's always did me good.

 

A lot of manufactures dont. I don't have half of the stuff on my web-site I have tuned, built, sell, etc.
